1 The concept of visual speed indication
The visual speed indication and thereby the attempt to influence the driver's speed is quite a
new field in the common road and traffic technology, although the well known traffic lights are
established since decades. Nowadays public authorities start to install luminary speed indication
signs above highways for the same purpose and additionally to manage the traffic flow. Besides
avoiding traffic jams, these systems also shall decrease the drivers speed in order to reduce the
rate of accidents and the heaviness of their consequences.
Our system of a mobile, autonomous and numerical speed indication display fulfils this aim
especially in communal and urban areas, speed limit zones, living areas and in front of schools
and nursery schools.
If we look to the effects of such a speed display, we can state three main effects:
The driver gets the speed of his car publicly displayed and realizes his „over speeding“.
Therefore the most drivers will be set under psychological pressure and reduce their actual
speed.
The inhabitants of living areas with low speed zones can prove the driving speed of passing
vehicles objectively and as far as local source and target traffic is concerned speak with well
known „fast drivers“ personally.
The communal authorities, often quite helpless with complaints of angry citizens about over
speeding, get an appropriate tool to react. With this tool they delegate in a psychological way
the control function to the concerned citizens.
The police are and was never able to observe the mentioned low speed zones and living areas
in a repressive manner effectively and the expenses for repressive supervision there are not
covered by fines for over speeding drivers. By the way, whether repressive supervision of
speed limitations in living areas is politically suitable is another question.
Up to now the only possibilities of local administrations are road reconstructions to lower
drivers speeding. But such steps are quite costly and under the aspect of the economic situation of the communities, with low funds not longer practicable.
The systems for visual speed indication however make sense in a wide area covering action.
This wide area covering action just can be run by easy installable and transportable units,
working completely independent for an appropriate time.
Since 1994 via traffic controlling has delivered the speed measurement systems viasis with integrated display. The viasis 3003 is an actual version of this system with low energy
consumption, integrated battery buffered memory for speed and time data, serial data interface
and a couple of different operating modes.
The possibility not only to measure and to display speed data, but also to collect and herewith
to analyze the collected values statistically grants a control of the effectiveness of the viasis
systems in a certain traffic situation.
In common speed data can be collected (with or without ‘publicly’ displayed speed on the
board) and later on processed statistically permitting the system user profound statements
about the car drivers speeding behavior on a certain road. This makes decisions for or against
further measures, like road reconstruction, repressive speed controls and so on, much easier.

Measured and stored data from a viasis can be read with a personal computer, a notebook or
laptop with serial RS232 interface and the delivered viagraph software working with Windows
XP/Vista/7/8 and Windows 10.
If you want to use the serial RS232 interface of the viasis, but your computer offers only a
USB interface, you can obtain a serial USB-RS232 adapter from us, see annex chapter 10.1 –
list of viasis equipment.
4 System description
The viasis 3003 measures and displays vehicle speeds of one drive lane and direction. The
viasis is an accumulator supplied, mobile measurement system, particularly designed for lowest
power consumption. Measured speeds are shown on a 300 mm high, seven-segment LED
board with 2 ½ digits. The used high brightness LED are mounted behind a rigid “phantom
light” mask to avoid seemingly display of speeds due to sun or vehicle light reflection.
Alternating with the numeric speed display, several warning and speed limit sign symbols with
a circle diameter of 300 mm can be shown. Optionally the viasis 3003 is equipped with two
LED display colors, with the possibility to change the displayed color according the comparison result of measured vehicle speed and a set speed threshold.
Measured vehicle speeds are stored in the viasis, marked with time and date of the measurement and can be later transferred by means of a serial communication interface like RS232,
USB or other optional radio data interfaces, like Bluetooth or GSM/GPRS mobile phone. The
viasis can be set to measure data of both driving directions of a two lane road and to store the
data for later evaluation.
Typically the viasis measures periodically every 1.5 seconds and shows the result. In case of a
new vehicle measurement the display is refreshed after 1.5 seconds, otherwise the display is
hold for maximal 3 seconds.
The measuring unit consists of a continuous wave „Doppler Radar“, a permanent sending high
frequency radio wave emitting and receiving unit, whose antenna is not visible through the
front window pane. This measuring unit delivers the received signals by an amplifier and digital
processing electronic to a microprocessor unit that evaluates the signals.
The viasis 3003 is delivered with numerous options, see also chapter 6.3.6, in several variants
like viasis COMPACT, MINI, PLUS, PLUS SMILE, etc. for various different applications.

5 Start-up with the viasis
5.1 Mounting and Fixation
The viasis must be mounted orthogonal to the road and stable in a height of 2 meters till 4
meters below the housing edge, see . First mount the system and finally insert the battery.
Illustration 1: Vertical orientation
Following items must be observed:
Another mounting height or a strong inclination of the housing (exceeding 90° ± 8°) may
influence the distance range of the vehicle detection and the accuracy of the displayed speed
values.
The radar detector in the viasis needs „free sight“ on the measured vehicles. Avoid a mounting behind trees, poles, high parking vehicles and so on.
The system shall not be used in the range of road turns and bends. Otherwise too low measured speeds can be the result.
For the fixation of the viasis at pole clamps use the delivered M6 slide nuts. Pull two slide nuts
in each C-profile rail at the backside of the viasis housing. With 2 x 2 M6 screws (not delivered) the pole clamp is fixed at the slide nuts, respectively the profile rails.
We offer a solid and lockable pole fixation kit for the viasis, see annex list of equipment chapter 10.1 and our website www.viatraffic.de.
If there is no possibility to mount to already existing poles or if the system is used only in short
mobile campaigns, we also deliver a mobile tripod, see annex list of equipment, with a telescope pole. If you use a mobile tripod you should be aware that you need to guard the system!

5.2 Horizontal orientation
Direct the system horizontally through turning the system board around the mounting pole.
The ideal orientation to reach a maximum distance range depends on the local circumstances.
Illustration 2: viasis display directed to the road with a measurement angle
= 5°
For the first the system should be straightened parallel the roadway and can be turned until a
measurement angle of 5 to the lane (see illustration 2) until the vehicles are detected from
the unit at the maximum distance range.
If leaving traffic reduces the distance range remarkably, the system board can also be turned
away from the roadway up to a measurement angle of 5 (see illustration 3).
Illustration 3: viasis display directed away from the road with a measurement angle
= 5°
A measurement angle of more than 5 lead to the display of too small speed values and may
cause measurement errors outside the specified accuracy.
5.2.1 Leaving traffic
The system is adjusted to approaching objects (toward the front side of the board). Leaving
objects are also detected but filtered out.
Practically also leaving traffic can cause a distance range reduction. Because the object with
the highest reflection amplitude, under certain circumstances the leaving traffic can be dominant for a short time and therefore „blinding“ the detector, although this detection is filtered
out and is not displayed.
If necessary the display board can be turned away from the leaving traffic lane within certain
limits to get an undisturbed detection, see also chapter 5.2.

viasis 3003 user manual
5.2.2 Crossing traffic
Diagonal crossing traffic passing the radar beam can lead to a disturbing speed value display.
By following measures you can reduce the detection distance range of the radar:
Decline the viasis housing vertically (see illustration 1) up to 8° towards ground.
Reduce the sensitivity of the radar receiver, see also chapter 6.3.7.
If both measures show no satisfying results there is nothing to do as to get away from the
crossing traffic.
5.3 Viasis MINI text panel
During the mounting the fixed text of the viasis MINI is folded in the visible upright position
by means of a movable flap board, see illustration 5.
If the flap board is open and upright both hinges are
fixed with rotatable hooks in this position, see also red
arrow in illustration 4.
Illustration 5: Open flap board
The fixation hook is hanged into the slot
at the hinge and secured by tightening
the knurled nut above.
Illustration 4: Fixation hook
The closed flap board is attached to the housing
during transport by two hidden magnetic holders.
Attention: Don’t forget to tighten the
knurled nuts before you transport the
viasis MINI. Otherwise they may get
loose and lost together with the hooks.

5.4 Electrical preparation
Illustration 7: viasis control panel
Untighten the knurled nut of the battery attachment,
turn the fixation bolt aside and insert the battery into the box. Secure the battery in its position
with the turn bolt and by tightening the knurled nut, see also illustration 7 and illustration 8.
Warning: Hold the battery always and as long as possible with both hands.
Secure the battery immediately after insertion with the turn bolt. Falling down
batteries can cause severe injuries.
Plug the connector of the battery cable into the
socket of the control panel labelled Akku
12VDC, see also illustration 7. The 5 ampere
system fuse should already be placed into the
fuse holder on the control panel. Press the
On/Off toggle switch (labeled 1/0) in position 1
so that the viasis is turned on.
Illustration 7 shows the viasis control panel in
the open battery box with USB connectors. Only
if optional USB interfaces are equipped the
green function control LED (USB-Link) can be
found, which is lit during the viasis power on
initialization time.
Directly after power on, during initialization the
viasis shows “188” on the numeric LED display
for about 3 seconds. Further 3 seconds the battery voltage is shown, for example 13.2 representing a viasis supply voltage of 13.2 Volt.
Hereafter the system is ready for operation and
the display is empty until the first vehicle is deIllustration 8: Battery box and control panel
tected.

viasis 3003 user manual
Later in cyclic offline measurement mode the green function control LED is lit during the radar
measurement, what means typically all 1,5 seconds for 50 to 100 milliseconds.
The lead acid accumulator batteries are only partly charged after delivery. Before you start a
longer measurement campaign charge the battery to its full capacity. Otherwise the operating
time will be reduced. In order to power the system on, the battery voltage level must be above
11,3 Volt.
Attention: Wait 5 seconds or more to repower the viasis after you powered it
off before. Otherwise malfunctions and error messages of viasis components,
which did not reach the off state completely, can be caused.
Take care not to press or damage the battery wires, when you close the box cover.
The battery box can be protected against unauthorized access with a padlock through the foreseen holes in battery box body and cover, see illustration 8.
The Viasis is configured for permanent operation after delivery (see also chapter 6.3) and is
ready for operation.

6.2.2 Using an USB-RS232 serial adapter
Connect the USB-RS232 serial adapter to a free USB port of your computer. Depending on
which Windows operating system you use, the presence of the USB-RS232 adapter is recognized by Windows as soon the adapter is plugged in. A message like “new hardware detected”
is shown and you will be asked to install a driver for the USB device.
For the installation of the USB device driver please refer to the instructions of the USB adapter package. The adapter package in common includes a CD-ROM with the needed device
drivers and installation instructions.
If the USB-RS232 interface adapter has been correctly installed as a serial COM port, you may
check it in the windows “Device manager”. Unfortunately the way to, respectively the placement of the device manager varies with the different Windows operation systems. In the
Windows 7 desktop click “„Start – Control Panel – System and Security – Device Manager”. Under Windows XP/Vista the “Device manager” is found in the “System properties”
register “Hardware”, see illustration 12.
Illustration 12: System properties
Open the „Device manager“ and expand the line
„Ports (COM & LPT). The USB-RS232 adapter
must be listed here below.
Hint: In case you use several different
USB sockets to connect the adapter
you may have to reinstall the USB driver.
Illustration 13: Device Manager
Now connect the USB-RS232 adapter to the viasis with the delivered RS232 cable, connect
the battery and proceed as described in chapter 6.2.1.

6.2.3 USB host interface connection (optional)
If the viasis 3003 is delivered with USB interfaces the USB sockets USB-A (for memory
sticks) and USB-B (PC connection) are placed on the control panel, located in the battery box,
see also illustration 14.
Before you can establish a USB
data connection with your computer you need to install an
USB device driver, see chapters
6.2.3.1, 6.2.3.2 and 6.2.3.3.
The used driver is a Windows
standard

driver
Illustration 14: Control panel with USB sockets
“usbser.sys” for a so called CDC
(Communication Device Class)
device, which also sets up a virtual COM port (a virtual serial interface), which can be used by
terminal programs.
The USB driver installation should preferably done with administrator user rights.
The USB-Link LED is lit continuously as soon you plugged the cable in the viasis USB-B
socket and a USB-A socket of your computer.
For a proper operation be aware of:
The viasis cannot be supplied by the USB interface, therefore the viasis
must by powered e. g. by a charged 12Volt battery for establishing a
data connection.
The internal viasis microcontroller has physically only one USB
host/client interface, which can be configured either as a host or client
USB interface, so either a PC connection can be made or else a USB
memory stick shall be plugged in, but both will not work the same
time.
During power on initialization (USB-Link LED lit) no USB connection shall exist or shall be established. As soon the viasis completed
initialization and the LED begins to flash shortly make a USB connection.
In case the USB connection to your computer is made by means of a
USB hub, the data transmission speed can be reduced remarkably.
Always close the data connection before you unplug the cable. In
viagraph this is done by closing the main window, e. g. in the terminal
program HyperTerminal exists a connect/disconnect button to separate and close the connection. Otherwise the programs may hang up or
do not recognize a reconnected viasis.

USB flash drives or memory sticks can be plugged in the USB-A socket of the control panel
located in the battery box, see also illustration 14.
Following points shall be recognized for a trouble free operation:
As long as a USB memory stick is plugged into the viasis control
panel no other data connection between the viasis and a computer,
particularly no USB host connection shall be established.
The USB interfaces of the control panel fulfills the USB 2.0 specification. According a USB client interface need to deliver maximal 100
mA for „low power“ mass storage devices.
The USB memory stick shall only be plugged for the time of a data
transfer and be removed afterwards. As long as the USB memory
stick is plugged in the viasis does operate in measurement mode
After connection of a USB memory stick the viasis executes in sequence following tasks:
If not found in the USB stick root directory a folder “VIASIS” is created
Download of stored measurement data in a file (*.VTF) in the “VIASIS” folder. Stored
measurement data in the viasis are deleted afterwards.
If a firmware file1 (*.BIN) is found in the “VIASIS” folder it is loaded and a firmware update is started.
In case a parameter file (file extension *.PAR) is found in the “VIASIS” folder it is loaded
into the viasis and the viasis is reconfigured.
If not already created before a new the log file “USBINFO.TXT” is placed in the
“VIASIS” folder. All up- and download actions are logged herein.

For the operation of USB memory sticks at your computer in common no customer
installed device driver is needed, because they can be operated with already installed
Windows standard mass storage device drivers
6.2.4.1 Parameter transfer from and to the viasis using a USB memory stick
The viagraph software allows it to modify viasis settings offline and to store the settings in a
parameter file on a USB stick. When the USB stick is plugged the next time in the viasis the
parameter settings are read and the viasis is reconfigured.
With viagraph created parameter files (file ending *.par) are named with the unique serial number of the viasis (e. g. 15SC4321.PAR) and are only loaded by the viasis with the same serial
number. So several parameter files can be placed in the “VIASIS” folder of a USB memory
stick for several viasis systems.
The precondition for the modification of the viasis system parameter settings offline is that the
viasis type and version is already known to the viagraph program:
Either you connect the viasis directly to your computer and click on the “Settings“ button in
viagraph, see also chapters 6.2.1, 6.2.3 and 6.2.5, resp. illustration 10 and illustration 11.
Else plug an USB stick into the powered viasis to retrieve a VTF file, see also chapter 6.2.4.
Afterwards plug the USB Sticks into an USB port of your computer and „evaluate“ the VTF
file with the viagraph software.
The actions of first possibility are already described before in the manual. For the second possibility start viagraph by the viagraph button on your desktop. In the viagraph program
selection, see also illustration 10, choose Read evaluation file.
Plug in the USB stick and
open the VTF file in the
VIASIS folder of the
viasis system, whose setting you want to modify
later, see illustration 31.
The VTF file probably
may contains no measure
data, therefore you are
prompted with a viagraph
error message, which you
can ignore.
Close
and

6.2.5 Bluetooth modem connection
Check whether you computer is equipped with a Bluetooth radio interface ready for operation.
If not you may obtain e. g. a USB Bluetooth dongle and install the device driver and operating
software delivered by the manufacturer.
Depending on the operating system of your computer and the installed Bluetooth interface,
either internal or external modem, the way to establish a Bluetooth data connection will vary.
Therefore for internal Bluetooth modems please check the online help system of your computer and for external Bluetooth modems solution check the installation and operation manual of
the manufacturer, delivered with the modem.
If standard (generic) Windows Bluetooth interface drivers are used for the Bluetooth modem
operation, the initial configuration of the Bluetooth connection is shown for Windows 7 below:
Open Devices and Printers by the
Windows Start menu or the Control
Panel. In the Devices and Printers
window, see also illustration 21, click
to Add a device in the menu bar.
The viasis Bluetooth module is ready
for operation ex factory and reported
e. g. with the device name
VIASIS_15SC9991, where 15SC9991
is the 8 character long viasis serial
number.
During the connection setup you are
further asked for a pairing code or pin
number. Enter here the default in the
viasis set four digit pin number 1234.
Illustration 34: Reported found new device(s)
Illustration 36: Pairing code, pin number
Illustration 35: Bluetooth device added
If the Bluetooth connection is established successfully the later started viagraph software
can find the viasis, otherwise not.

viasis 3003 user manual
If you use other terminal software or make a manual terminal connection with
viagraph you need to know which virtual COM port number was assigned to the
Bluetooth device and set the COM port in the terminal program accordingly. This
COM port number can be either found in the Windows Device manager, see chapters 6.2.2 and 6.2.3.1 or else with a right mouse click to the device, which was added in Devices and Printers, menu item Properties in the Services tab, see also illustration 37 below:
Illustration 37: COM port number of the serial Bluetooth device
The radiation of the Bluetooth antenna and therefore the zone where radio connections are
possible is similar to the radar in front of the display. Directly aside, below and behind the
viasis a connection is only possible if reflectors (buildings, fences or vehicles) are nearby.
Internal Bluetooth modems of laptops, notebooks and mini computers are in
common designed for the connection of peripheral Bluetooth devices like keyboards, mouse, mobile phones, which are placed close by your computer.
Therefore their radio transmission strength and reception sensitivity is often quite
bad. In such a case turn off the internal modem and invest a few Euro for an external class 2 or
better class 1 USB Bluetooth dongle, with which you can have a much better and stable distant
Bluetooth connection.
If you have already established some Bluetooth data connections to different viasis or more
generally to via devices in the past and these devices are still reachable while you try to connect in viagraph with Connect to device you may experience the fact that viagraph
automatically connects to the first found via device and not to the device you wanted viagraph
to connect to. In this case you have choose the connection and the device manually, please see
chapter 6.2.7.

6.2.6 Data connection by GSM radio modem, Email and SMS transfer
If you like to transfer data or parameter of the viasis by GSM radio link you need
in common to obtain a second GSM radio modem for the communication with your
remote computer1. The radio modem must support CSD2 protocol data communication. Further on you need two SIM cards of a provider, whose radio network
supports explicitly CSD data transfer with 9600 Baud data transfer speed.
For the use of E-mail data transfer and automatic viasis SMS alarm messages you need SIM
cards and contracts which include GPRS and SMS services. You may ask if the provider offers
contracts with data transfer only (without voice) services for business customers.
Before you obtain the SIM cards ask the provider if he covers the needed radio services
(CSD, GPRS, SMS) at the viasis measurement place(s) himself. Roaming service, the radio
service by a contractor of your radio service provider might be paid with high charges later on.
Regarding the questions „How to connect, install drivers and setup your radio modem at your computer”,
please refer to the information given by the radio modem manufacturer. Finally a virtual COM port must
have been created in the Windows Device manager,
typical either in the device class COM&LPT or Modems – Properties – Extended, see also chapters 6.2.2
and 6.2.3.
Before you can connect with viagraph3 or another
minal software, check that the viasis is powered and the
radio modem is switched on by its related time
ule and (if needed) the PIN number of the SIM card is
set in the viasis, refer also to chapters 6.4.2.1 and
6.4.2.2.
In order to establish a connection with viagraph click
the button Connect to device see illustration 10 in the
viagraph start window.
After the modem was found the Modem screen is
shown, see also illustration 38. Enter the dialing number of the SIM card inserted in the viasis in the field
Number. In the Comment field enter a unique description for the viasis.
Illustration 38: Viagraph radio modem support
Laptop or notebook integrated radio modems or “surf sticks” often offer an integrated modem with a virtual COM port for
various radio link protocols. But in almost all cases they do not provide CSD protocol capability . Therefore check if CSD
explicitly listed in the modem features in the provided manufacturer information.
CSD – circuit switched data
Viagraph expects a radio modem inserted SIM card with switched off PIN number request. This can be done by inserting
the SIM card in a mobile phone. Please follow the mobile phone manual, how to do it.

6.2.7 Manual selection of the viagraph communication (COM) port
The manual selection of the communication (COM) port might be necessary, in case of:
- multiple connections to different via devices are possible, but with the Connect to device
search only the first found device is automatically connected.
- several modems with virtual COM ports are installed at your computer. Viagraph always
offers only the first found modem, which is the inappropriate one for a GSM connection to the
viasis device.
- several Bluetooth connections were established in the past, each with a COM port number,
some viasis with Bluetooth modem are in reach, but only the first found device is automatically
connected by viagraph.
In this cases or a combination of them, please have a look in the Windows Device manager
(see chapters 6.2.2 and 6.2.3), particularly in the device classes COM&LPT, Bluetooth devices and Modem to find the COM port number of the wished viasis device or modem.
Illustration 40: Viagraph terminal connection
Start viagraph and select Terminal from the Tools menu, see also illustration 32. The initially
empty terminal window appears. In the COM port selection field select the COM port of the
wished viasis device or modem. The data transfer rate must be always 115200 Baud. as shown
in Illustration 40. Now click the Connect button.
As soon you are connected the Disconnect button is shown. Now, you can use the Tools button, to force viagraph to show the defined extended functions for a recognized viasis or radio
modem, like Read data, Settings or Dial number, see also illustration 11 and illustration 38.

way.
The settings for Bidirectional detection, Optimizing display and Radar sensitivity are the
same for all parameter sets and times.
6.3.1 Parameter set
A parameter set is the collection of all display parameters of the submenus Speed display options and Extensions thresholds and its submenus for the times defined in the submenu Time
Schedule.
Up to 5 complementary parameter sets for different periods can be used for a variable measurement and display behavior. This can be used for example during school hours in order to set
a different display behavior in case of a temporary speed restriction, as to the other times of the
day off school and weekends, for example at 30 km/h, from Monday till Friday, from 7:30 to
13:30 o’clock only.

6.3.2 Time schedule
Each parameter set, see chapter 6.3.1, owns a time schedule, which determines during which
times the settings of the parameter set are used by the viasis for the measurement, display and
possible extensions
Time schedule:
1. LED display: on
2. Operation weekdays: Su,Mo,Tu,We,Th,Fr,Sa
3. Daily start time: 00:00
4. Daily stop time: 00:00
5. Back
Your choice 1...5?
The values of the time schedule shown above are the default values for parameter set 1 ex factory. All weekdays are operation weekdays and the daily operation time is the whole day in
case daily start and stop time are set to equal values. So parameter set 1 is valid the whole
week for each day. For the other parameter sets is by default no operation day defined, therefore they are deactivated.
In time periods not covered by the
time schedules, no measurements
and self evident no display operation will happen. The viasis is in a
low power energy saving mode,
without active radar and the viasis
will be “awaked” only at the next
valid time schedule time entry.
If the operation time of two or more
parameter sets overlap, always the
parameters of the lowest number
parameter set get valid.
In viagraph the time schedules of all
parameter sets are concentrated in
the input windows „Scheduling“,
which gets visible by activation of
the menus Tools – Parameter sets –

Your choice 1...7? _
The chosen day of the week is added to the list of operation days in the Time schedule menu,
if it was not listed before, respectively removed from the list, if it was listed.
6.3.2.3 Time schedule – Daily start and daily stop time
The daily start and stop time determine the daily time of the measurement and display operation at the chosen operation weekdays (chapter 6.3.2.2).
If the Daily start time and the Daily stop time is set to the same time values, these times are
ignored by the system and the task is performed at the whole selected operation weekdays.
You have to insert the time values in the format hh:mm. Valid are time values between 00:00
and 23:59.
Examples:
1. You intend to measure in front of a school only during school visiting times. Only at
schooldays from Monday till Friday, in the time from 07:30 till 13:30 the viasis shall measure
and display the vehicle driver’s speed.
Following settings must be made in parameter set 1 in the time schedule menu:
- Set LED display to „on“.
- Change the operation weekdays to „Mo,Tu,We,Th,Fr“.
- Set the daily start time to „07:30“ and the daily stop time to „13:30“

- If set, the operation weekdays of the other parameter sets must be discarded.
2. You want to measure at a road construction site by night from 19:00 till 06:00 display the
vehicle driver’s speed. But you want to measure the whole day around the clock.
Following settings must be made in parameter set 1 in the time schedule menu:
- Set LED display to „on“.
- Change the operation weekdays to „ Su,Mo,Tu,We,Th,Fr,Sa “.
- Set the daily start time to „19:00“ and the daily stop time to „06:00“
Additionally following settings need to be done in parameter set 2 in the time schedule menu:
- Set LED display to „off“.
- Change the operation weekdays to „ Su,Mo,Tu,We,Th,Fr,Sa “.
- Set the daily start time to „6:00“and the daily stop time to „19:00“
In the second example with the time schedule of parameter set 1 a measurement with numeric
speed display is made from 19:00 till 6:00 o’clock each night. During the daytime from 06:00
till 19:00 o’clock the time schedule of parameter set 2 measures without displaying the speed
on the numeric LED display.
6.3.3 Bidirectional detection
The viasis radar detects also the data of leaving vehicles, whose data by default are not stored
in memory and whose speed in principle are not shown on the numeric LED display. The feature Bidirectional detection allows an additional memorization of data of leaving vehicles for
later data evaluation purposes.
If you enter 3 in the „Settings” menu you are prompted to change the Bidirectional detection
state:
Bidirectional detection
1. off
2. on
Your choice 1...2?
Is the Bidirectional detection set to “on” you are given in the Online measurement menu the
speed data of vehicles of both driving directions by the serial data connection(s), see chapter
6.6.
Hint: The bidirectional detection delivers only at low traffic density, respectively low
vehicle meeting rate, complete and meaningful data for the leaving vehicle traffic,
whose vehicles cannot be detected as long they are in the radar shadow of approaching vehicles.
The setting for the Bidirectional detection is valid for all parameter sets. In viagraph the feature Both directions can be activated in the Tools menu of the Settings window.

6.3.4 Menu Speed display options
The menu Speed display options is shown if you choose 4 in the Settings menu:
Speed display options:
1. Decimal places: off
2. Minimal speed displayed: 5 km/h
3. Maximal speed displayed: 199 km/h
4. Threshold blinking LED: 200 km/h
5. Threshold Led mixed color: 200 km/h
6. Threshold LED color change: 200 km/h
7. Back
Your choice 1...7?
The parameter values shown above are the default values ex factory.
For viasis LED displays with only one LED color the options Threshold LED mixed color
and Threshold LED color change do not exist. The Threshold LED mixed color is only
shown for viasis with two appropriate LED colors. The options given in menu “Speed display
options”, with exception of the Decimal places, need to be defined for each activated parameter set.
6.3.4.1 Decimal places
For applications where low vehicle speeds shall be measured exactly, e. g. for drive in weighbridges, the display of a decimal digit until 19,9 km/h (or mph) can be activated by entering 1
in the Speed display options menu and further activating the decimal:
Decimal places
1. off
2. on
Your choice 1...2?
If vehicle speeds above or equal 20 km/h are measured the speed values are displayed on the
numeric LED display as whole numbers again. If the speed decimal is activated the speed data
output in the Online measurement (chapter 6.6) mode, is also given with a decimal digit.
The setting for decimal places is a general setting equal for all parameter sets.
6.3.4.2 Minimal - and maximal speed displayed
The „Minimal speed displayed“ is the lowest measured speed value published on the numeric
LED speed display
In the “Settings” menu you are prompted after the selection 4:
Minimal speed displayed = _
End the numbers input with . The new value is shown in the menu immediately.
The values for minimum speed can be set in the range between 5 and 199 km/h. Only values
lower or equal the adjusted maximum speed will be accepted by the system.
Page 33 of 85
via
traffic
controlling
gmbh
viasis 3003 user manual
You may raise the minimal speed factory setting of 5 km/h to e.g. 15 km/h to suppress slow
movements of vehicles, pedestrians or wind moved branches of trees, which may also initiate
measurements on short distance.
The „Maximal speed displayed“ is the highest measured speed value shown on the numeric
LED speed display. With the 2 ½ - digit LED display you may set the value between adjusted
minimal speed and a maximum of 199 km/h.
The reduction of the Maximal speed displayed to values just above a local speed limit (maybe
plus 20%) avoid the driver testing of the maximal shown speed or „tachometer checks“.
The setting of the Maximal speed displayed parameter is analogue the setting of the Minimal
speed displayed. The setting can be changed by the selection 5 in the Settings menu.
Both settings have no influence on the speed data storage and the output of serial data. All
speeds measured between 5 km/h and 199 km/h are stored, respectively transferred to a connected computer terminal.
Hint: By setting minimal and maximal speed displayed to equal values e. g. to 5
km/h, the vehicle speed data are memorized, resp. transferred to a connected terminal, without an output on the numeric LED display for the vehicle drivers, see also
chapter 6.3.2.1.
6.3.4.3 Threshold blinking LED
Depending on the excess of the „Threshold blinking LED“ by the measured vehicle speed, the
numeric speed display is alternated for 0.25 seconds on and 0.25 seconds off time. In a display
update cycle with 1.5 seconds length the numeric speed „blinks“ up 3 times in short sequence.
This function can be used to reduce the power consumption of the system, with the effect of
nearly doubling the system operating time without battery recharge. Hereby the threshold value
is set to the minimum speed.
If the threshold is set to a local speed limit, this function can be used to point over speeding
drivers to their misbehavior, with the effect of a blinking (warning) display when the speed
limit is exceeded.
The threshold is set like the other thresholds in the range from 5 km/h till 200 km/h (blinking
deactivated).
6.3.4.4 Threshold LED mixed color (Option)
If the viasis is equipped with two LED colors, which can be shown at the same time and emit
seemingly a third color, the parameter “Threshold LED mixed color” is shown. Practically if
the viasis has e. g. green and red LED the result of displaying both colors is the mixture color
yellow, which is displayed if a measured vehicle speed exceeds the related, set threshold.
The speed threshold parameter is set similar to the speed threshold LED color change, see also
chapter 6.3.4.5.
For example if the viasis is equipped with yellow and red emitting LED the color sequence of
the display yellow – orange – red would be chosen with rising measured speed values, the
mixed LED color threshold (orange display) would be set to 31 km/h and the threshold LED
color change to 41 km/h.
Is the LED mixed color threshold set to a higher value than the LED color change threshold it
will have no visible effect on the display.

6.3.4.5 Threshold LED color change
The viasis is supplied in several versions, with a numeric LED display with one or two LED
colors. Only the two color versions have a menu item for changing the LED display color dependent of the measured vehicle speed. The color of the numeric speed display changes, for
example from yellow to red color, if a detected vehicle moves faster than the set “Threshold
LED color change” speed limit.
Also this option can be used to indicate the vehicle drivers that they drive too fast and their
vehicle speed exceeds the local speed limit.
The threshold is set like the other thresholds in the range from 5 km/h till 200 km/h (numeric
speed display color change deactivated).
6.3.5 Optimizing display
The viasis is equipped with a sensor for the environment brightness. With the measured values
the needed brightness of the display LEDs for a good visibility is calculated and controlled.
With the menu Optimizing display the LED display brightness can be influenced if needed:
Optimizing display
1. Operating time
2. Balanced
3. Visibility
Your choice 1...3?
If the option Operating time is chosen the display appears darker and reaches maximal 50% of
the possible brightness adjusted ex factory. If you choose Visibility the LED display appears to
be brighter in compare to the Balanced setting. Here the viasis reaches the adjusted maximal
brightness earlier and needs up to 50% more battery energy with the consequence of having a
reduced operating time with battery supply.
6.3.6 Menu extensions thresholds
The viasis can be equipped with several optional extensions, which can be divided in two
groups.
One group are the LED display extensions in form of LED warning symbols, which are integrated in the numeric LED speed display field, which are shown alternating to the numeric
speed values, see chapter 6.3.6.1.
The other group consists of controlled switches as relays or power MOSFET transistors
switches or switched optical output units, like LED warning lamps, LED matrices with text or
symbols, which are activated additionally to the numeric LED speed display at the same time,
see also chapter 6.3.6.2 foll.
All switches or output units are activated by the excess of a set speed threshold by
the measured vehicle speed. More precisely an “on and an off speed threshold can
be set for each symbol, switch or peripheral device.

Depending on the warning light features (uni-/bi- or tricolor) the items of the menu will vary.
The LED of the warning light are switched on or off synchronously to the numeric speed display in case the related on/off threshold is exceeded by the measured speed value. The speed
threshold for the activation/deactivation of the LED color(s) of the warning light can be set
between 5 km/h and 200 km/h (threshold deactivated).
6.3.6.4 Relays and power MOSFET transistors (optional)
The viasis 3003 can be ordered with up to 7 galvanic isolated low voltage relays, appropriate
for switching up to 230 V mains voltage or alternatively with up to 7 high current MOSFET
power transistor to switch 12VDC loads, technical data see chapters 10.3.5.
The connection is made either in an external waterproof (IP65) connection box with number
labeled screw clamps or the viasis is delivered a connection cable (and scheme) ex factory.
For three installed relays the menu for their related speed thresholds in the menu Extensions
Thresholds – Relays will look similar to the following menu:
Relays
1. Relay 1 on: 31 km/h
2. Relay 1 off: 51 km/h
3. Relay 2 on: 51 km/h
4. Relay 2 off: 61 km/h
5. Relay 3 on: 61 km/h
6. Relay 3 off: 81 km/h
7. Back
Your choice 1...7?
The relays or MOSFET transistors are switched synchronous to the numeric speed display in
case the related speed thresholds are exceeded by the measured vehicle speed. In the menu
example above relays 1 is switched for measured speeds from 31 km/h till 50 km/h.
6.3.6.5 LED display pages or additional LED fixed text (viasis PLUS or PLUS SMILE)
The submenu Display pages is placed in the menu Extensions Thresholds in case the viasis is
equipped with additional LED fixed text or symbols (variant viasis PLUS SMILE) or a LED
full matrix (variant viasis PLUS) below the numeric speed display for the display of additional
text or symbols.
For an additional board with three fixed texts the related menu may look as follows:
Display pages:
1. THANK YOU on: 5 km/h
2. THANK YOU off: 31 km/h
3. SLOW DOWN on: 31 km/h
4. SLOW DOWN off: 41 km/h

For LED fixed texts (PLUS SMILE) the displayed text or a symbol name will be used to label
the menu items, for LED full matrices with variable texts and symbols the menu items are labeled only as numbered LED page (1, 2, ... etc.).
For each text or symbol can be defined an „On“ and „Off“ threshold between 5 km/h and 200
km/h (threshold deactivated).
The text or the symbol is switched synchronous to the numeric speed display if the related
threshold is exceeded by the measured speed value. Moreover the switched outputs (relays, ...,
display pages) are also activated outside the range of the set minimal and maximal speed displayed thresholds for the numeric speed display, so that for example with the viasis PLUS
additional text like “Slow down” can be also shown without having a numeric speed displayed.
For viasis PLUS SMILE with LED fixed text the activation range of two or more
texts shall not overlap. The simultaneous display of two fixed texts will cause an
unreadable result.
The viasis PLUS shows in case of the simultaneous activation of two or more LED pages, the
pages in an alternating sequence each for the time of measurement cycle (typ. 1,5 s). This feature can be used e. g. in bi-lingual regions to show additional text in two languages in an
alternating manner. For example Led page 1 shows the text „THANK YOU“, Led Page 2
shows the welsh text „DIOLCH YN FAWR“, the „On“ threshold for both pages is set to 5
km/h and the „Off“ threshold to 30 km/h – as result for the time of detection of a 28 km/h driving vehicle the texts „THANK YOU“ and „DIOLCH YN FAWR“ are shown alternating each
for 1,5 seconds.

The device name is the chosen name for the viasis Bluetooth devices shown if you search for
connectable devices under Windows on your computer.
The Trusted device list are the Bluetooth hardware addresses of computers to which the viasis
was once successfully connected.
The Trusted device list might have to be cleared :
if more than 20 Bluetooth addresses are already shown in the list. Herewith the list is full

terminal.
6.4.1.1 Bluetooth device name
The so called local device name can be changed and is set by default to „VIASIS-15SC9991“,
wherein “15SC9991” is the unique viasis serial number. After you selected 1. Device name in
the Bluetooth menu you are asked to enter the new device name:
Device name = MyBluetooth001
The character string is to be ended by pressing the  key. The device name may consist
of 1 till 40 characters. Avoid special characters, apostrophes and similar, because they are in
common interpreted by connection software and this often in a different way.
6.4.1.2 Pin number
If you choose 2 for the Pin number in the Bluetooth modem menu you are asked to enter a
new pin number:
Pin number=8241
The pin number itself can be changed, the length of the pin number can be up to 8 digits. All
numbers from 1 till 99999999 are valid pin numbers. If a not correct pin number is send by a
connecting computer the connection is refused by the viasis, therefore the number protects the
viasis from unwished access.

3. Daily stop time: 18:00
4. Email delivery: None
5. Back
Your choice 1...5?
The setting of the GSM Operation weekdays and the Daily start/stop time is done similar as
the settings made in the time schedule for measurement and LED display, please refer to the
chapters 6.3.2.2 and 6.3.2.3.
The menu items Operation weekdays and Daily start/stop time define only the
days and the time span during which the viasis GSM/GPRS modem remains
powered and can be called by a dial up GSM connection. The delivery of Email
and SMS messages and data works independently from the herewith defined time
schedule and are also send outside the here defined days and times.
To reduce the available times, where the viasis radio modem can be called, means to extend the
operating time of battery supplied viasis systems remarkably. This due to the fact that the basic
power consumption while measuring without active LED display is four times higher if the
GSM/GPRS modem is powered. A 24 hour availability of a radio connection to the viasis is in
common not needed, because reconfigurations are necessary quite seldom, most often during
workdays and only in the common working times (08:00 till 18:00). For an individual time
setting and a possible further reduction of the power consumption you can use the described
menu items.
During an active GSM connection the modem is not powered off. The modem is switched off
as soon as the connection is closed hereafter.

2. Memory full
3. Daily
4. Weekly
5. Monthly
Your choice 1...5?
The selection Memory full sends a mail with the measurement data as a file attachment if more
than 95% of the data flash storage of the viasis is full.
Further you can choose the time intervals Daily, Weekly or Monthly. If you select them additional menu options for the delivery time and possibly the date appear in the menu. For this
options always a mail is send also if no measurements were stored in the selected time interval.
If you select Daily mail delivery you need to define the daily delivery time:
4. Email delivery: Daily
5. Time: 03:00
The time value is set in the format “hh:mm”, with time values between 00:00 and 23:59.
For the mail delivery interval Weekly additionally the day of the week, where the mails shall be
send must be set:
4. Email delivery: Weekly
5. Time: 03:00
6. Weekday: Wednesday
If you enter “6” for the Weekday selection a sub menu is shown, which lists all weekdays for
your choice.
If the mail delivery is set to Monthly the day of the month need to be given instead:
4. Email delivery: Monthly
5. Time: 03:00
6. Day of month: 1
Legal month values are 1 to 28 only in order to avoid delivery gaps in the short months of the
year, e. g. in February.
Further hints:
Use delivery (night) times with low traffic density and low GPRS data transfer
volumes. During the time the mail needs to be delivered no vehicle data can be
measured and stored. The minimal delivery time for e. g. an 4 MB data long mail
is ~12 minutes. The GPRS upload bandwidth must be shared with other devices
uploading data to a radio base station.

Whether an E-Mail or SMS must be delivered is checked once per minute by the viasis. If a
delivery cannot be done due to an active Bluetooth, USB or GSM data connection, the transfer
its started within a minute after the closure of the connection. Is a viasis powered off during
the scheduled time of delivery, the E-mail will not be sent after the next power on anymore.
An E-mail delivery is valued valid as soon as the mail server (SMTP-server) acknowledges
the data reception and the server connection is closed regularly. In this case the stored and
transferred measurement data are erased in the flash memory automatically. Otherwise the Email delivery is repeated within a minute after the failure and until the transfer is successful.
Be aware if you use the daily interval a lot of small data files is created, which must be
merged later on to be able to create e. g. a week long evaluation.
6.4.2.2 SIM card PIN code
The input of the PIN1 code or the request of its set status can only be done by a serial RS232
cable connection. Access by the GSM, Bluetooth or USB data connections is refused with the
message “No access possible”.
Select the GSM/E-mail menu item “2. Pin number” to enter the 4 digit PIN code delivered
from the service provider together with the SIM card, for example:
Pin number=1234

In case the SIM card is already inserted in the push/pull SIM card holder located at the control panel backside in the battery box you should receive following answer:
+CPIN: READY
OK
In case of an error or problem you get one of the messages listed in the table below:
+ CME ERROR: SIM not inserted
+ CME ERROR: incorrect password
ERROR / ERROR SIM PIN
+CPIN: SIM PIN
+CPIN: SIM PUK3
SIM card not in the SIM card holder, not
readable or defective
Entered PIN code is wrong
PIN code wrong or already inserted
PIN code required
PIN code setting failed 3 times, SIM card is
locked. You can unlock the SIM card externally only, e. g. by inserting the SIM card in
a mobile phone and insertion of the 8 digit
long PUK code 4.
If you enter  only at the PIN code prompt the status of the PIN setting
is delivered without a setting and one of the status messages above are output.
Repeated insertion of the already set correct PIN code is illegal.
PIN – „Personal Identification Number“ - 4 digit long numeric pass code
SIM – “Subscriber Identity Module” – Component for radio network user identification
PUK – „Personal Unlock Code” – 8 digit long unlock code to be found in SIM card accompanying information of your
GSM/GPRS service provider.
Guidance for the procedure is in common documented in the manual of your mobile phone

viasis 3003 user manual
In case the PIN code request of the SIM card was already switched off or you change later
to a SIM card with switched off PIN request you need to delete an earlier entered and stored
PIN code by insertion of PIN number = 0 .
For the protection against misuse and theft the inserted PIN code cannot be requested
Attention: Never change the PIN code arbitrarily. The PIN code is
send from the viasis to the radio modem after each modem power on
automatically. After 3 failing attempts the SIM card is locked and the
PUK code is requested further on.
In case the inserted PIN code is rejected check your provider information first before you retry it again.
6.4.2.3 GPRS configuration
If you select “3. Configure GPRS” in the GSM/Email menu you will receive the current GPRS
configuration. The following example shows the configuration ex factory:
APN: not set
USER: not set
PASS: not set
ROAMING: off
Change (y/n)?
In case you answer the question “Change(y/n)?” with “y” for yes, the APN (access point network), the related USER username and PASS pass code will be requested sequentially by the
viasis. Valid entries are up to 31 alphanumeric characters, but without question mark, colon
and double point. The text string must be ended with . Entering  only will
skip the request and the setting remains unchanged.
Thereafter you can allow or deny roaming connections, what means connections made instead
of your service provider by another provider, which will bill the connections separately to your
provider. This is in common accompanied by much higher connection charges.
You may configure GPRS access by all viasis serial interfaces (RS232, GSM, Bluetooth and
USB). But only by using the RS232 connection the configuration is immediately tested and the
protocol is send to a connected terminal:
Configure ...
AT+CGATT=0
AT+CGDCONT=1,"IP","internet.t-mobile"
AT+QICSGP=1,"internet.t-mobile","tm","tm"
AT+CGATT=1
AT+QIMODE=1
AT+QIREGAPP
AT+QIACT
AT+QILOCIP
+IP: 100.76.160.156
GPRS ok
In case of a problem or an error while establishing the GPRS connection the sequence above
ends with „Error GPRS“. If you configure by other interfaces as RS232 connection a direct

6.4.2.4 Configuring the SMTP-Server (Mail server)
For the configuration of the mail server enter “4” in the GSM/Email menu and you will receive
the actual settings for the E-mail delivery to the SMTP1-Server:
SMTP-SERVER: smtp.viaxmail.de
SMTP-PORT: 25
EHOST: viaxmail.de
EUSER: send@viatraffic.de
EPASS: ****
MAILFROM: viasis@viaxmail.de
Change (y/n)?
The shown settings are the default settings ex factory and are valid data if you intend to use
our mail server for the E-mail delivery. The viasis connects the SMTP server only for the for1
SMTP – simple mail transfer protocol
Page 47 of 85
via

controlling
gmbh
viasis 3003 user manual
warding transport of the viasis E-mail to the final destination mail server of the recipient E-mail
account(s), which you have to enter in “5. Configure Email” (see next chapter) of the
GSM/Email menu.
Note: The use of our SMTP-server takes place on own danger and under exclusion of
any liability on the part of the via traffic controlling GmbH.
If you answer “y” to the question “Change (y/n)?” you will be prompted for each SMTPserver setup entry. For valid inputs in the text fields see the insertion of APN, USER and
PASS in the previous chapter.
The input fields in detail:
SMTP-Server – URL1 name of a mail server which is ready to receive E-mails delivered by the
viasis. The mail server only forwards (relays) emails to the recipient(s). Alternatively to the
URL name the IP address (e. g. 192.86.102.245) of a SMTP server can also be inserted.
SMTP-Port – Up to 5 digit long port number (1...65535), at which the mail server listens to
mail delivery attempts. Typically mail servers listen at port 25, but this may differ for single
SMTP servers.
EHOST – Host name of the E-mail sender
EUSER – Senders user name of its E-mail account at the mail server. In common the E-mail
sender owns a user mail account at the providers mail server. Nowadays rarely exist also open
mail (relay) server forwarding each mail they get from whoever, with no authorized login
needed or allowed. If you use such an open relay server delete user name EUSER and password EPASS.
EPASS – Password of the above described user E-mail account. For the authentication of the
mail sender needed password for the login as user at the mail server. For open relay server the
password shall be deleted, see above. In order to avoid misuse by unauthorized third persons
the set EPASS password is output as a “******” string only.
MAILFROM – E-mail address of the mail sender
A configuration change of the SMTP-server access data can be done by all serial interface connections (RS232, GSM, Bluetooth or USB) of the viasis. But only if you are connected by
RS232 directly the access to the SMTP-Server and if he is ready to receive E-mails from the
viasis is tested and a protocol send to a connected terminal (example):

If the connection between viasis and SMTP-server could be established and the server declared
ready to receive E-mails from the viasis you will finally see the message “SMTP-Server ok”
otherwise “Error SMTP-Server”.
If you enter  only, the text entry is skipped and the text field content remains unchanged.
To delete the content of a text field to the state “not set” enter  followed by .
Be aware that mail servers have often limits concerning the maximal length of E-mails. Most
mail servers limits are above 10 Megabyte (= limit of our providers mail server) but in some
known cases also below. A viasis with 8 MB flash storage installed is capable of producing 12
MB long E-mails in case the storage is full. The reason is the 30% increase in data volume due
to the needed base64 coding of the binary measurement file attachment. Ask the mail server
provider about existing limits before you start to send E-mails.
In case you need to contact our technical support, please provide the protocol of the failed
SMTP-server configuration, which is essential to analyze the problem.
6.4.2.5 E-mail configuration
With the GSM/Email menu item “Configure Email” you can define the recipient(s) email address and whether E-mail alarm messages are send or not. First the actual configuration is send
(example):
MAILTO: technik@viatraffic.de
MAILCOPY: not set
Email alarm: on
Change (y/n)?
Differing from the example no E-mail address is set by default and the E-mail alarm is switched
off. To change the setting enter “y” to the “Change(y/n)?” prompt. Valid input for the sequentially asked text fields MAILTO and MAILCOPY are maximal 31 alphanumeric character long
E-mail addresses. Excluded characters are question mark, colon and double point. Further is
valid things said about the text field input of the previous two chapters.
MAILTO for the recipient of the E-mail and MAILCOPY for the recipient of an Email copy
shall contain only a single E-mail address, no lists are allowed.
With activated E-mail alarm the viasis will send E-mails for the events of “Measurement storage > 95% full”, “Battery voltage < 11,5V” and for system errors. The system error emails
include up to the last 8 viasis protocol entries, see also chapter 6.5.1. The E-mails are send
latest after the minute of the occurrence of the event or failure.
Page 49 of 85
via

controlling
gmbh
viasis 3003 user manual
If you respond ‘y’ to both questions “Change(y/n)?” and “Send email(y/n)?”, a test E-mail is
send and if you a connected locally by RS232 (only), you will see the delivery protocol of the
send E-mail:
Send Email...
AT+QILOCIP
+IP: 100.66.122.19
AT+QIDNSIP=1
AT+QIOPEN="TCP","smtp.viaxmail.de",25

354 End data with .
250 2.0.0 Ok: queued as 8DB438049D
QUIT
221 2.0.0 Bye
EMAIL ok
In case the E-mail was send correctly and the mail server accepted the E-mail for forwarding,
you get the final “Email ok” message and otherwise “Error Email”. Moreover the E-mail recipient should receive a status E-mail with just the line “E-mail delivery set!”.
By means of the “Configure E-mail” menu item you may also send currently stored measurement data immediately if you respond ‘n’ to the question “Change(y/n)?” but ‘y’ to “Send
email(y/n)?”.
If you are connected by RS232 the E-mail is send immediately, else if you are connected by
GSM, USB or Bluetooth interface, the mail is send as soon as the active connection will be
closed.
If you need to contact our technical support, please provide the protocol of the
failed test E-mail delivery, what is important to analyze a problem.
6.4.2.6 Configure SMS
The menu item “6. Configure SMS” in the GSM/Email menu is used to enter the needed
phone numbers for the SMS1 delivery and to activate the delivery of SMS event and error messages:
SMS SERVICE CENTER2: +491710760000
SMS phone number: 016312345678
SMS alarm: off
Change (y/n)?
Legal insertions for the SMS service center number and the phone number of the SMS recipient are up to 16 digits long. The number of the service center is always entered with plus sign
SMS – short message service for text messages consisting of maximal 160 characters
SMS Service Centre (SMSC) receives SMS messages from the telephone/radio network, forwards and stores
messages if the receiver is currently not reachable.

headed international country dialing code. The phone number of the SMS recipient needs to be
entered without country code. Moreover the hints to legal text fields contents given in the
previous chapters 6.4.2.3 till 6.4.2.5 shall be observed.
If the “SMS alarm” is active, short messages for the events “Battery voltage < 11,5V”,
“Memory > 95% full” and “System error” are send within one minute after occurrence.
If you change the SMS configuration and respond “y” to the “Send SMS (y/n)?” question, you
should receive a test SMS with the content “SMS delivery set!”. If your computer is connected
by RS232 cable locally, the protocol of the SMS delivery is shown in the terminal window:
Send SMS...
AT+CSCA="+491710760000"
AT+CMGF=1
AT+CSMP=17,167,0,241
AT+CNMI=2,1,0,0,0
AT+CMGS="016312345678"
SMS ok
If the SMS delivery was successful the protocol is ended with “SMS ok” otherwise with “Error SMS”. Similar to the delivery of E-mails the delivery of SMS is delayed if you are
connected by GSM, Bluetooth or USB interface until this active connection is closed.
If you face problems with E-mail or SMS configuration or delivery and contact
our technical support, please provide the connection protocol as text or snapshot
attached to a send E-mail. The connection protocol is essential for a failure analysis.
6.4.3 GPS Module (optional)
In case the viasis 3003 is equipped with a GSM/GPRS modem an additional GPS module for
the determination of the position of the viasis can be build in. The position data are determined
regularly and they are transferred as a position list to viagraph. The last position is also send in
the text of the viasis emails:
Information:
Viasis 3003 - Version 4.16
Serial number: 15SC9991
Active parameter set: 1
Interface options: Bluetooth, USB, GSM/Email, GPS
GPS: 20.09.15, 09:45:00, 51°03.5615',N, 007°00.9070',E
Date: 20.09.2015, Sunday
Time: 11:15:33
Number of values = 24274, Memory full: 6 % Battery voltage: 13,17 V
If you open a viasis measurement data file (*.vtf) with viagraph or you make a direct connection to a viasis with GPS module and click the Tools menu in the viagraph menu bar of the
Settings window, see illustration 33, the menu item GPS coordinates is selectable.
If your computer is connected to the Internet and after a click to the Tools menu item GPS
coordinates viagraph will open your standard web browser with the Google Maps web site and
sends the viasis GPS coordinates.
The web browser shows then the map with the last viasis position, see illustration 47:
Page 51 of 85
via
traffic
controlling
gmbh
viasis 3003 user manual
Illustration 47: GPS coordinates of the viasis position in Google maps
In a direct connection to the viasis the last, most current GPS position is displayed. From an
open vtf measurement data file the first GPS position of the chosen evaluation time period is
shown.
If you enter 3 in the Radio modem menu in the viagraph terminal you will receive the menu for
the GPS module:
GPS menu:
1. Position list
2. Formatted data output
3. Raw data (NMEA-183)
4. Position fix time: 24h
5. Back
Your choice 1...5?
Due to the high energy consumption of the GPS module the position determination is not done
permanently. Instead the position is determined after the viasis power on and further continuously repeated after the time set in the Position fix time. The fixation of the position, may just
need 30 seconds but also up an hour at unfavorable mounting positions, where the viasis is
placed in the satellites signal shadow behind large buildings, walls, trees or other obstacles.
After the position data are determined the GPS module is immediately shut down.
During the GPS data output, see chapters 6.4.3.2 and 6.4.2.3, the measurement of vehicles is
stopped, but not during the set regular position fixes.
6.4.3.1 GPS position list
After insertion of 1 in the GPS menu you will get first the number of stored GPS positions, for
example:
Number of GPS positions = 5
Send data (y/n)?
Page 52 of 85
via

viasis 3003 user manual
If you enter ‘y’ the output of the position list will start:
30.09.15, 15:47:00, 51°03.5647',N, 007°00.9108',E
30.09.15, 11:46:00, 51°03.5574',N, 007°00.9081',E
30.09.15, 07:45:00, 51°03.5587',N, 007°00.9086',E
30.09.15, 03:41:00, 51°03.5593',N, 007°00.9076',E
29.09.15, 23:40:00, 51°03.5599',N, 007°00.9082',E
Delete data (y/n)?
Up to 25 GPS positions can be memorized. Because the oldest position in the list is automatically overwritten by the newest position it is in principle not necessary to clear the list ever.
Separated by colons the viasis system date (DD.MM.YY) and time (hh:mm:ss), the latitude in
degree and minutes with 4 decimal digits, N/S for northern/southern latitude, the longitude in
degree and minutes with 4 decimal digits and finally E/W for eastern/western longitude of the
fixed position is shown in a line.
To make the correlation between viasis measurement data and GPS coordinates easy, the viasis
system date and time and not the satellite time (UTC1) is stored in the GPS position list.
6.4.3.2 Formatted GPS data output
After entering 2 for Formatted data output in the GPS menu, you will get following hint first:
End with 
What means you can stop the formatted output of GPS coordinate data by pressing the
 and the ‘z’ key simultaneously.
After the repeating headline the result of the GPS position determination follows once per second:
Satellites,UTC,Latitude,N/S,Longitude,E/W,HDOP

10,073032,5103.5587,N,00700.9050,E,0.84,
The first number is number of found satellites. As soon the first satellite signal is received by
the GPS menu the UTC satellite time, here 07:30:02 (AM) appears.
UTC – Universal time coordinated
CTRL – control key, depending on your keyboard, might also labelled with CTL or likewise
Page 53 of 85

viasis 3003 user manual
As soon 3 to 4 satellites signals could be found appears the output of position data – the latitude in degree and minutes with 4 minute decimals, the N/S latitude information and the
analogous data for the longitude.
The last number, the HDOP1 value is a measure for the horizontal, two dimensional variation
of the measured GPS data. GPS position data with a HDOP value greater than 10 are not precise and not usable.
With the GPS data output you may check if a sufficient number of satellites respectively the GPS position is found at a viasis mounting place within a
reasonable time. In tunnels or in between high buildings the determination of the
GPS position might be impossible. In such a case switch the GPS position determination off, see chapter 6.4.3.4, in order to avoid a permanent searching GPS module with
the consequence of a reduced operation time of a viasis with battery supply.
6.4.3.3 GPS raw data (NMEA-183 protocol)
The GPS raw data output delivers position data coded according the nautical standard NMEA2
developed for the communication between navigation system of ships. These ASCII block data
send once per second are a bit confusing, but include numerous information, amongst other
things e. g. to the satellites, whose data were used for the calculation of the position:

$GPGLL,5103.5574,N,00700.9062,E,073114.000,A,A*57
In the Internet and the literature a lot of publications describe the contents of the NMEA-183
data blocks, therefore we resign to do it here.
Similar to the formatted data output, see chapter 6.4.3.2, the output of the GPS raw data can
be stopped by simultaneous pressing of the  and ‘z’ key.
6.4.3.4 GPS position fix time
A few minutes after the viasis power on the determination of the GPS position is done. The
Position fix time is the time period after which the determination is regularly repeated.
After insertion 4 in the GPS menu, following prompt appears:
Position fix time =
You may enter values between 1 and 255 hours for the position determination interval. The
default value is 24 hours. If you enter 0 the determination of the GPS position is deactivated.
If no valid GPS position can be determined within 60 minutes, the position search will be cancelled and the GPS module will be switched off until the next viasis power on in order to avoid
a fast unwished battery discharge. This might be the case when operating the viasis within
buildings, tunnels or behind high buildings.

The first line Viasis 300M3 Version 4.16, H4 includes viasis type designation, software version number and hardware release. The second line displays the unique serial number of the
viasis device. Serial number, software and hardware release should be always at your hands in
case you contact our technical support.
Active parameter set shows the number of the active parameter set of the measurement and
display operation, at the time the menu is called. If at this time no parameter set is valid the
number 0 (null) is given.
The item comments shows typically information like measurement location or other given user
information, see also chapter 6.5.2. The comment line is missing if not set.
In case that radio modem interfaces like Bluetooth, GSM/Email or other optional serial interfaces as USB are installed and detected during the power on initialization of the viasis they are
listed in the last line of the information header.
6.5.1 Protocol
The viasis system includes a ring buffer for a protocol of event and error messages. If the ring
buffer is full the new messages overwrite the oldest messages. An explicit deletion of old messages is for a proper function of the protocol therefore not necessary.
If the protocol is selected by the entry 1 in the menu Information and time the number of
stored messages is displayed and you are prompted, whether the protocol shall be send or not:
Number of log entries = 25
Send data (y/n)?
If you insert „y“ for yes, the list of protocol messages is send (example):

Each protocol entry is followed by date and time of occurrence.
After the output of the protocol you are prompted, whether the protocol shall be deleted or
not:
Delete data (y/n)?
As already mentioned you may erase the protocol, for an actual, continuous operation of the
log is this not necessary.
The size of the protocol message buffer depends on the size of the installed flash memory and
is for 2/4/8 MB storage 191/191/255 protocol entries.
6.5.2 Comment – text field
In the comment text field a text string with a length of 80 characters can be stored. In most

6.5.3 System date and time
The date is to be entered with long year format after the choice 3 in the menu Information
and time. That means dates with year century digits from 01.01.2011 till 31.12.2099 are legal.
The viasis checks all date values within this range for correctness. Together with the date value
the actual day of the week must be set. The correct operation of the parameter set time schedules (chapter 6.3.2) require a correct setting of the day of the week.
The system time can be set with the selection 4 in the menu Information and time to time
values between 00:00:00 and 23:59:59 o’clock.
Incorrect inputs as wrong separator characters, time or date values are rejected by a repetition
of the input prompt.

A call of the menu items Date and Time is refused by the viasis as long as measurement data
are stored. This to avoid inconsistent measurement sequences, which may cause later problems
during the data evaluation. In case you receive the message „Access impossible!“ if you try to
change system date or time then download and store the measurement data first. Erase the data
and hereafter the change of time and date will be possible.
The real time clock of the viasis never stops and works continuously with the internal lithium
buffer battery if the lead-gel main battery is removed. The operating time of the lithium battery
is minimum 7.5 years. As more often the viasis is in operation, supplied from the main battery
as longer lasts the lithium buffer battery.
6.5.4 Daylight saving time
By pressing the key 5 for the Daylight saving time in the menu Information and time you can
define its use. In the European Community the daylight saving time is used uniquely from the
last Sunday in March till the last Sunday in October. The changes occur uniquely in all member
states at 01:00 UTC (universal time) time.
In the displayed sub menu, please select the correct time zone for your country:
Daylight saving time:
1. off
2. UTC+0
3. UTC+1
4. UTC+2
Your choice 1...4?
For the United Kingdom, Ireland, Portugal please choose “UTC+0”, for Spain, France, Germany, Poland “UTC+1” and for Greece and Finland “UTC+2”. For countries in time zone
“UTC+1” (MEZ) the clock will be altered from 02:00 to 03:00 local time in March and from
03:00 to 02:00 local time in October.
The selection 1 in the menu will switch the daylight saving time (Summer Time) off.
6.6 Online measurement
The transfer of currently measured speed data over a serial data connection (cable RS232,
USB or by radio Bluetooth and GSM modem) is done if you select the Online measurement
in the viasis main menu.
After the hint  sends the viasis vehicle speed data synchronous to the
measure cycle all 1.5 seconds as long as a vehicle passes the radar beam towards the viasis.
If the option Bidirectional Detection in the Settings menu is activated, see also chapter 6.3.3,
additionally the speed data of vehicles passing the radar beam away from the speed display are
send headed by a minus sign ‘-‘.
The speed data are send as ASCII numbers, with variable width, what means one till three digits, followed by the control characters carriage return (hex 0x0A) and line feed (hex 0x0D),
what means one speed number per line.
So far the numeric display was not deactivated by the parameter LED display: off, see chapter
6.3.2.1, the speed measurements are also still shown on the numeric LED display.

6.7 Data memory
The viasis measurement data store is organized as a ring storage, so in case the memory is full
the oldest stored data are overwritten by the newest data. Herewith is guaranteed that the
viasis still keeps the most actual data in case of a data overflow, respectively a too sporadic
measurement data download and deletion.
The viasis is either delivered with 2, 4 or 8 megabyte non volatile flash memory. The herein
stored data have a retention of 20 years minimum according the manufacturer and the memory
cells can be rewritten 100000 times (write/erase cycles), what means a total of 100000 measurements and parameter changes can be done, before statistically a memory failure should
occur.
The measured speed data stored as data blocks with 10 byte length in the memory. Therefore
the storage capacity (minus some bytes for parameter and log protocol) is depending on the
storage size of 2, 4 or 8 MB finally 212160, 425125 or 842952 measurement data blocks. This
is equivalent at a radar range of 120 meter and an average vehicle speed of 50 km/h about
36833, 73806 or 146345 vehicles.
The measurement data store should be deleted after a data download in order to keep the
amount of read data and the data transfer times small.
6.7.1 Read measurement data
For the download of stored measurement data of the
viasis you can use the program viagraph delivered on
CDROM, see chapter 6.1.3 or the ViaApp for
Android Smartphones, see chapter 6.1.1.
Illustration 48
In order to start the data download with viagraph the
data connection to the viasis must have been established successfully, see also illustration 11.
Click on the button „Read data“ and the data transfer progress appears, but maybe just for a
glimpse depending on the number of data, see illustration 48.
Next the dialogue to save the
data in a file appears, see illustration 49.
You may change or extend
the proposed file name. In
order to keep a good overview over numerous data files
you may e. g. add the measurement location to serial
number and download date
already given in the filename.
With a click on the “Save”
button store the data to your
computer’s hard disk drive.

viasis 3003 user manual
Select whether you want to delete the measurement data in
the viasis or not, see also illustration 50.
Also in case the viasis measurement data storage is empty a
file with the file name extension *.VTF (“via traffic format) is
created. The file includes the protocol with event and error
messages, the current parameter setting of the system and
eventually GPS position data.
Illustration 50
6.7.2 Checking stored measurement data
A check how much and which measurement data are stored in the viasis you can make by entering 1 for “Transmit stored data” in the main menu, see also illustration 11.
If no values are stored the viasis returns immediately back to the main menu, otherwise it reports the number of stored speed values:
Number of values = 21233
It follows the question:
Send data (y/n)?
If you enter y the measurement data are send to the terminal, always 25 lines before you are
prompted to continue with :
25;16.12.11;16:52:10
-32;16.12.11;16:52:12
44;16.12.11;16:52:33
38;16.12.11;16:52:35 ...

Per line one speed value optional headed by a minus sign indicating leaving vehicle detection,
with date and time, and separated by semicolons is send. If you press any key other as 
the output is ended.
After the data output or if you entered n for Send Data (y/n)? following message appears:
Delete data (y/n)?
If you enter j for yes in the terminal all data are deleted, if N for no is given the current measurement is continued. In case the ring data storage is full the oldest data are overwritten by the
actual data.

6.8 Test functions
The test functions menu is shown if you enter 3 in the main menu, see also illustration 11 .
Test functions:
1. LED display
2. Flash memory
3. Real time clock
4. Main battery
5. Simulation
6. Light sensor
7. Back
Your choice 1...7?
The test LED-display shows first „19.9“ on the numeric LED display in the LED base color,
then if equipped in the second LED color and if defined in the last optional mixed LED color
with rising brightness in 1%, 2%, 4%, 8%, 16%, 32%, 64% and 100% of the maximal brightness each time for 1,5 seconds. The current value of the LED brightness is also transferred via
data connection to a terminal.
If the LED mixed color is defined „124“ is displayed in varying color balances, afterwards
„124“ is shown in blinking mode in the installed LED colors.
For the following LED display up- and down count test the start and end count value is taken
from the set minimal- and maximal speed displayed parameters defined in parameter set 1,
see chapter 6.3.4.2. Each count value is shown ¾ seconds on the numeric LED speed display.
Further the thresholds for blinking LED display, LED color change and LED mixed color, as
well as for the integrated warning symbols defined in parameter set 1 are recognized for the
equivalent display. Optional installed extensions see chapter 6.3.6, are activated during the upand down count test depending if their on/off threshold is exceeded by the count value, or not.
The Flash memory test indicates the installed memory size first:
4 MB Flash installed
The flash memory test destructs stored measurement data and the event protocol, therefore
follows the question:
All data will be deleted
Continue (y/n)?
If you perform the test the proper function of all memory cells is checked by erasing and rewriting the cell contents:
Erase Page: 4096 ok
Write Page: 4096 ok
The flash memory cells (bits) are organized in so called pages (256, 512 or 1024 bytes of 8
bits). In case of an error the test stops at the erroneous page and the error is reported. Else the
proper memory function is confirmed with ok after the last page was tested.
The test of the Real time clock includes beside the output of date and time a compare test between a microcontroller and a real time clock time, generated from their crystal oscillator
frequencies. Is the compare time difference smaller than 50 ppm (parts per million), equivalent
Page 60 of 85
via
traffic
controlling
gmbh
viasis 3003 user manual
to an error of less than about 30 seconds per week, the message „RTC ok!“ is send, otherwise
the error is reported in ppm units.
The Main battery test allows the measurement of the lead-gel accumulator voltage and estimation about its charge condition. The measurement is made in contrary to the battery test during
power on initialization without load, that means without active LED display of „188“ and can
be initiated therefore also remotely by a GSM modem. The result is given with 0,1 Volt resolution between 10,7 and 13,8 Volt (17 Ah accumulator discharge and full charge voltage levels).
The test Simulation is useful in order to check the numeric LED speed display but also for a
functional test of installed system extensions, as additional text displays, switches like optocouplers, relays or warn lights at a simulated vehicle, without the need to install and measure
on a road site with vehicle traffic. Further the made parameter settings defined in the parameter
sets, resp. their effects on the behavior of the numeric LED display can be simply tested.
After the test is called you are asked to enter a test speed and the number of the parameter set,
whose parameters shall be recognized for the simulation:
Test speed=51
Parameter set=1

The test speed value is compared with the speed threshold parameters defined in the parameter
set, resp. the threshold parameters of the Settings menu and the submenus Thresholds Extensions and Speed display options, for the numeric LED display, the integrated LED circle
symbols, optional extensions and they are activated accordingly.
Only if the test speed in the range between set minimal and maximal speed displayed, see chapter 6.3.4.2 the test speed is shown on the numeric LED speed display. By pressing the
 key the LED display and all system extensions are reset and deactivated.
The environment Light sensor, which measures the brightness of the environment, delivers for
a functional check a numerical result:

Light sensor: 955
The result drops in bright sun light down to zero. In dusk, dawn and darkness the given results
are high and tend up to the maximal value 1023. In case the sensor value does not change despite illumination e. g. with a torch or by dark covering, it is defective. The position of the light
sensor in the LED display board is approximately in the middle, right aside the hundred digit.
6.9 Data evaluation
The evaluation of measured speed data is done with the delivered software viagraph. The installation of the evaluation program viagraph is already described in chapter 6.1.3.
A detailed description of the evaluations you will find in the online help of the viagraph program in the menu Help – User Manual1.
In order to read the help documents you need to install Adobe Acrobat Reader Version 3 or higher. In the internet you will
find Adobes website with http://www.adobe.com/.

6.10 Viasis PLUS display
The add-on display board of the viasis PLUS is in general a two line LED full matrix with own
separate microcontroller with the „Viamatrix“ firmware and a flash memory for the display
text, bitmap graphics and display parameters.
The following description shows how configure
the viasis PLUS by using the viagraph input
window, which is reached by a click on the Matrix button, see illustration 11.
The viasis PLUS display can also be completely
configured by using any terminal software and
the Viamatrix menu system, which is called by
entering  in the viasis main menu:
Viamatrix menu
1. Text messages
2. User character bitmaps
3. Test functions
4. Parameter
5. Information
6. Back
Select 1 .. 6
Illustration 51: Viasis PLUS
From the Viamatrix menu you get back to the viasis menu if you enter ‚6’ for Back.
Attention: Before you close a communication connection and if you used the
Viamatrix menu before - return always to the viasis menu. Otherwise the
Viamatrix program will wait for further menu insertions and will not show
any matrix message until you returned to the viasis menu.
The Viamatrix program has an input menu timeout of 30 seconds until it returns automatically
back to the next upper menu level or resp. to the viasis menu, what makes the “forgot to return” problem less grave. But depending on the Viamatrix menu level where closed the
connection it still may need several minutes until matrix messages are given again.
The Viamatrix software Test functions and the Information menu are not supported by
viagraph and can be reached therefore only by the menu system.
As the viasis parameter settings the matrix display pages, bitmaps and parameters can be set
offline if you click on the menu Extra – Matrix – viasis PLUS in the viagraph start window,
see illustration 32. Together with the viasis parameter settings a file can be created (see chapter
6.2.4.1) and stored on an USB flash stick for a later upload in the viasis.
The speed thresholds for the activation of the matrix display pages are part of the viasis parameter sets, see also chapter 6.3.6.5.

6.10.1 Viasis PLUS matrix editor – display pages
After a mouse click to the viasis PLUS Matrix button in the viagraph connection window
(illustration 11) the matrix editor appears and in case the viasis is directly connected with the
current settings:
Illustration 52: Matrix editor main window
The left part of the window is used to edit the LED display pages, each consists of two text
lines. Which page is currently enabled for editing is selected with the check boxes in the middle
column showing the current line contents, see illustration 52.
The two white input lines in the upper left corner of the window are used to enter the needed
display text or symbols. Legal are all printable 7 bit ASCII characters, what means letters, digits and most punctuation marks, except quotation marks (“), which are used to label bitmaps
and placeholders in the text.
Below the lines in the group field Line 1 scroll and Line 2 scroll determine the buttons Left,
Off and Right, if the line text is displayed static or if the text is scrolled through the matrix line
to the right or to the left.
In the group field Color you can define for a two color viasis PLUS matrix, which LED color
is shown and if the text is shown permanently or in a flashing mode.
The black back grounded output fields in the middle column of the windows show how the
text lines will be later displayed on the viasis PLUS LED matrix.
The entered text will be displayed centered in the matrix display. If you need a leftor right bound display add spaces to the right or left of the text.
Before you close the matrix editor, respectively if you modified all display pages as you wanted
send them to the viasis with the Transfer button otherwise all changes are lost.

Beside text the LED matrix can also show so called bitmap graphic. In the right column of the
matrix editor window up to 31 bitmap graphic characters can be defined:
Illustration 53: bitmap column at right side of the matrix editor
As bitmaps also country specific special characters, as Umlauts, apostrophic characters, etc.,
can be defined. By a click on the number button left of the bitmap the character or the graphic
is placed in the active line, respectively in its text at the current cursor position, see also illustration 53, Bitmap 17.
In the page line the bitmap is placed by its bitmap number, delimited by apostrophes (e. g.
’17’), therefore the use of apostrophes in the text is not allowed.
In order to edit or create new bitmaps double click with the mouse the bitmap picture behind
the number button and the bitmap editor will appear.
6.10.3 Bitmap editor
A pixel (LED) is activated / deactivated with a left/right mouse click
in the bitmap editor. With the button Delete all pixel are cleared.
Before you start editing the bitmap
set the width of your bitmap, resp.
the number of needed LED columns with Width button. The maximal width of the bitmap is the matrix column width, which can be
found in the Viamatrix menu Information.

6.10.4 Matrix editor menu Tools
In the matrix editor menu Tools – Text you will find the menu items Load and Save. With
Save you can store edited display pages on your computer hard disk in a text file (*.txt), with
Load you can load already saved display page text files.
Illustration 55: Matrix editor tools menu
If you click one of the Text menu items the Windows standard dialogues for “file save as”,
resp. “file open” will appear. Besides the text also edited bitmaps can be stored from or loaded
into the matrix editor by the menus Tools – Bitmap – Load and Save.
Predefined placeholder like date1, time in short format (hh:mm) or long format (hh:mm:ss) can
be inserted like bitmaps in the lines of the display pages, by a mouse click to the wished line
position and hereafter by a click to the menu Tools – Placeholder with the selection of Time1,
Time2, Date or Placeholder. Within the display page lines the placeholders are shown as
apostrophe delimited numbers, which start at ‘127’ (short time format), similar to the bitmaps
(‘1’ – ‘31’). The value or content of placeholders are determined or calculated just before they
are displayed.
Placeholders for time and date can be used for example together with a permanent shown text
page and a 230V net supplied viasis, see also chapter 6.11. Placeholders are further used in
special software which displays calculated money or point penalties depending on the measured
over speeding.
6.10.5 Permanent text page
The viasis PLUS offers the possibility to define a Permanent shown page, that means a display page shown if no other page is activated due to vehicle detection above the set speed
thresholds.
Be aware: The energy consumption of a permanent shown LED text in compare to the
short time activated, switched text due to vehicle detections, is very high and therefore
only appropriate for 230V mains supplied viasis PLUS. For viasis PLUS with 12V accumulator is this no option due to the strong reduction of operating time.
For the configuration of a permanent text page proceed as follows:
In the Viamatrix menu Parameter – Number of text pages, see menu chapter 6.10, rise the
number from 4 to 5.
In the Viamatrix menu Parameter – Permanent text page enter page number 5. Permanent
text page 0 means deactivated.
Return to the viasis main menu
The time and date clock of the Viamatrix, whose values appear in the matrix lines, are loaded from the viasis
real time clock (RTC) at power on. So changes at the viasis time and date settings, see chapter 6.5.3 get valid
on the matrix after the next power on.

If you click now the Matrix button in the viagraph connection window again the new 5. Display page gets visible if you scroll down with the scrollbar of the middle display column.
Together with the already set placeholders for date and time the permanent 5th text page looks
like in the matrix editor as follows:
Illustration 56: Matrix editor with date and time placeholder in permanent display page
6.11 Select switch option
For the selection of the display parameters the viasis can be optionally delivered with a rotary
turn switch. The turn switch is located in the accumulator box on the control unit board; please
see following illustration 57 below.
Illustration 57: Select switch parameter sets
Page 66 of 85
via

controlling
gmbh
viasis 3003 user manual
If the select switch is in position of the clock symbol the viasis works in normal mode. This
means the display parameters of the parameter sets 1 to 5 are activated by the time settings of
their weekly calendar.
In case the turn switch is in position 1 to 5 the display parameters of the selected parameter set
(see also chapter 6.3.1) are permanently active.
If the viasis is used at various, changing measurement locations with differing local speed limits, the switch offers the possibility to change quickly the display parameters to appropriate
values of an another parameter set.
7 Technical and physical properties
7.1 Distance range
The detection distance range of all microwave detectors depends to a large extend to reflection
properties of the measured objects and interference properties of the near surrounding.
In common is valid:
As bigger, planer and orthogonal to the microwave beam axis the reflection surface is,
as longer is the distance range.
As less absorbing and scattering the reflection surface, as longer is the distance range.
As more other objects are in measurement beam, as shorter is the distance range (diffraction scattering and foliage losses, shadow losses and so on).
Practically following factors have a reducing effect to the distance range:
High up to the edge of the driveway leading buildings, trees, poles, parked cars and
containers, which hamper the „free sight“ of the detector and/or lead to strong scattering losses.
Influence through weather, rain and snow lead to absorption losses of the radar
„Blinding of the detector“ through other moving objects as tree branches, persons,
resp. a reduction of the detection range by a too far in the leaving traffic directed radar
beam, see also chapter 5.2.
The above mentioned negative influences have practically a much smaller meaning than it may
seem now, but it makes clear that the reason for a too small distance range is only in rare cases
a deficient microwave detector.
In the free field the radar unit has a typical distance range of more than 120 m for genuine passenger cars. Each viasis is tested before delivery regarding a sufficient distance range. For
trucks the distance range is about 50% higher due to the larger reflection front surface, for
motorcycles it is reduced to 50% and less.
The distance from where the numeric LED display can be read due to the chosen digit size is
also higher than 120 meter.
The highest distance range has a detector mounted in a height of 2 up to 3 meter to the housing bottom side. This offset from the ground results from the practically necessary small
inclination of the microwave antenna inside the display housing.

viasis 3003 user manual
7.2 Measurement angle
The angle between detector beam axis and the movement axis of the detected vehicles has decisive influence on the measured speed. Microwave detectors and all on the physical „Doppler“
principle based measurement systems (some laser, most infrared and ultrasonic) do not measure the absolute speed of a vehicle. They measure the relative speed or exactly the angular
speed vector component of a vehicle moving towards the radar beam axis.
This is expressed by following formula:
vmeasure = vabsolute x cos
with : measuring angle
The ideal measurement angle is 0°, this means vmeasure = vabsolute and the movement axis and the
radar beam axis are identical in this case.
In practice the system board can only be mounted laterally, besides the driveway. But you
don’t get a measurement error outside the specified accuracy, if you are aware the limits of the
measurement angle (see chapter 5.2).
Please notice the following:
A too large measurement angle can only have a too small speed value as result!
Up to a measurement angle of 4° (equal to which direction) the relative speed measured by the detector and the absolute speed are the same through the rounding of
the not displayed digits.
7.3 Accuracy
The accuracy of the speed value is:
2% and
1 digit, for the whole measurement range
Herewith the accuracy is better than specified for repressive velocity measurement systems in
the German „Eichordnung“ of the „Physikalisch-Technische Bundesanstalt“ ( 3% for v > 100
km/h and 3 km/h for v < 100 km/h).
Despite this fact, this system is not used in Germany for repressive measurements, because it is
not equipped with a electronic calibration circuitry, what is claimed by the „Eichordnung“.
Also in future we won’t design the system in this way, because the pedagogical intention of
this system for visual speed indication would be mislead.
7.4 Display field and visibility
The display field consists of the 300 mm high LED digits and the 190 mm high digits of the
integrated warning symbols. The chosen letter sizes guarantee readability above 100 Meter.
The angle of readability of the LED digits is with 15° sufficiently high to be seen by the vehicle
drivers with full brightness also in bright sunlight. However for spectators looking from aside
the LED display just seem to glow depending on the viewing angle and may even disappear in
bright sunlight (similar to the fiber optic signs on highways). In common the visibility decreases
for LED with rising brightness of the environment a little bit.
A „phantom light mask“ is placed in front of the LED, which suppress a seemingly glowing of
the LED to a large extent when they reflect the sun light.
Page 68 of 85
viasis 3003 user manual
via
traffic
controlling
gmbh
To avoid blinding effects of the vehicle drivers, especially during night-time or covered sky, the
system is equipped with an environment light sensor and a LED brightness control with a resolution of 0,5% of the maximal brightness.
7.5 Display frequency
The update frequency of numeric LED display is identical with the measurement frequency of
the radar detector. As long a moving object is detected its speed is updated all 1,5 seconds on
the numeric LED display. The last measured speed value is hold for about 3 seconds on the
LED display.
The display cycle of 1,5 s has emerged as ideal in comprehensive tests. The driver perceives
the display frequency after interviews not as too high and therewith not too flurry. In contradiction, the driver sees the displayed speed from a quite far distance, realizes that he is over
speeding and slows down. On the display he (and the spectator) gets as a direct feedback the
reduced speed displayed, let’s say as reward and the driver passes the display with the correct
speed. Characteristic is that the driver has enough time to develop a feeling for the right speed.
Hereby is the high distance range the decisive advantage. At a shorter distance range, the driver gets his over speeding displayed, but there is no time for a „dialogue“ between driver and
display. The driver has no time to react and the feedback - the reward is missing as well.
7.6 Power supply and operating time
7.6.1 Accumulator version
For the power supply a 12 Volt lead gel battery pack with a capacity of 17 Ah is installed in a
small plastic box on the backside of the housing.
The viasis has a discharge protection for the accumulator to prevent irreversible chemical decomposition of the battery electrolyte due to long time discharge below 10,7 Volt. The
protection circuit disconnects the viasis from the battery when the voltage drops below 10,7
Volt and (re-)connects it when the battery voltage is 11,3 Volt minimum.
The operating time of the viasis relies essentially on the number of displayed speed values, the
environment brightness and self evidently on the battery capacity. In bright sunlight the power
consumption due to maximum LED brightness is maximal 11 Watt when displaying “188” on
the numeric LED display. By night with minimum LED brightness level the consumption is less
than 1 Watt for displaying “188”.
So the operating time of the viasis 3003 is at a display rate (relation between display on and off
time) of 25%, with calculated 16 day and 8 night hours, for the 17 Ah battery about two
weeks.
7.6.2 Mains supply 115/230 Volt AC version
Attention: For viasis delivered as 115/230 Volt AC version do not remove or
disconnected the buffer battery. The buffer battery delivers peak currents,
filters mains distortions and ensures that the voltage level of the AC/DC
power supply does not rise to illegal over voltage levels and blows the system fuses.
Additionally the buffer battery allows the operation of the viasis at timely powered light poles
and ensures an operation for several days if the mains line is switched off.
In rare cases with the viasis connected to a heavily distorted mains supply it might be necessary
to install a harmonic filter to ensure proper system operation.
Page 69 of 85
via
traffic
controlling
gmbh
viasis 3003 user manual
Attention: Work at 115V/230V installations must be generally carried out by
electro-technically trained personnel or specialized companies, according to
the relevant technical regulations
7.6.3 Viasis with photovoltaic solar support
Attention: Never operate the Viasis with solar panel and disconnected main
battery. Always connect the battery first before the solar panel.
The solar charge module needs a buffer battery for proper operation and the clamp
voltage of the solar module may rise in bright sun light to a destructive level for the electronic
without connected lead-acid gel battery.
7.7 Operating temperature
The semiconductor components used in our production including the LED’s are specified for
industrial applications. That means an operating temperature range from -40 to +85 Celsius
is guaranteed by the manufacturer.
The microwave transceiver is specified for an operating temperature range from -20 to +70
Celsius. Outside these limits the manufacturers give no guarantee for a faultless function.
7.8 Water protection
The industrial housing protection class is IP64 (compare EN 60529). IP64 means that the system is protected against intrusion of dust and the housing protected against water splashing
from any direction. The housing is in any case sealed against rain water.
Another thing is the problem of humidity, because the housing has two small drillings (Ø 2mm)
at the housing bottom for pressure balancing. Strong temperature differences between a housing interior and the surrounding produce a low pressure situation in the housing interior. Slow
pressure compensation with the intrusion of humid environmental air may settle down moisture
on the surface of the interior housing walls, also at the inner side of the front pane. The housing has the two drill holes in the frame on the bottom side for pressure balancing and the drain
of condensing water.
7.9 Radio wave interference
Through the use of stereo-channel Doppler transceiver (radio wave transmitter and receiver)
and an appropriate measure procedure with steady signal supervision the display of speed values caused by interfering radio waves of other systems can be excluded.
If the interfering signal is much stronger than the received radar signal of the viasis then the
system stops operation. In such rare case you need to change the measurement place.

8 Maintenance
8.1 Cleaning the front window pane
Attention: To clean a dirty front window pane use always a liquid antistatic
detergent or an antistatic cleansing towel!
Otherwise the transparent plastic front pane can be electrostatic charged up to several kilovolts (frictional electricity) especially when using dry paper or synthetic textile towels.
The discharge pulse may destroy the semiconductor components in the microwave transceiver.
A damaged or destroyed microwave transceiver reduces the measurement distance range or
leads to a complete failure of the measurement display.
8.2 Charging and testing the lead acid battery
The battery is discharged, if the voltage level drops below 10,7 Volt. The battery is separated
below this level through the integrated low level discharge protection. Recharge the empty
battery immediately to avoid irreversible chemical destruction.
Attention: The batteries shall be stored only in loaded condition at dry locations!
The self-discharging of our delivered batteries is with 0,1% (at 20°C) of the loaded
capacity per day very low, so that charged batteries can be stored also for longer times (½
year) without any problems.
The battery voltage level can be checked under load condition at power on („188“ is displayed
and the battery voltage value follows) and when you connect a laptop or PC and use the test
function „main battery“, see also chapter 6.8, but without load. Is the battery voltage level
below 11,3 Volt the viasis will not start operation.
For the battery loading you should use our automatic battery charger, which stops loading at
the high level battery voltage of about 13,8 Volt. If you use a battery charger with no overload
protection, it might destroy the battery chemically if a voltage level of 13,8 Volt is exceeded.
Reverse connection of batteries and charger are impossible with the viasis battery connectors
which allow a plug in the coupling only in the correct way.
Attention, if you use third party chargers: When connecting the cables of the
battery, take care of the right polarity! Connect the black minus pole of the
charger to the black minus pole of the battery and the red plus pole of the
charger to the red plus pole of the battery. Lead-acid gel batteries can be charged reverse
and herewith destroyed. Additionally the next connection to the viasis will cause a short
circuit and blow the fuse in such a case.
The time to load a completely empty 17 Ah battery with our battery chargers (load currents 2
Ampere) is approximately 10 hours to 90% of the battery capacity. The time to load the battery to full capacity (charger LED load control extinguishes) can be much longer.

8.3 Changing the battery
To withdraw the battery unfasten the cover brackets and open the cover of the battery box,
placed on the backside of the viasis display system.
Remove the plug of the battery cable from the control panel socket, see illustration 8. Untighten the knurled nut above the turn bolt, turn the bolt aside and take out the battery. To install
the battery proceed in reverse order.
Attention: In case of two or more batteries – disconnect all empty batteries
first before reconnecting the charged batteries. Otherwise the fuse(s) might
be blown, due to the high current flow between empty and full batteries.
When you close the battery box cover take care not to press or cut the battery cable
wires.
8.4 Changing the fuse
In order to change the main fuse open the cover of the battery housing on the backside of the
display system. The main fuse holder is placed in the upper right corner of the control panel.
Replace the fuse with a mini 5 Ampere inert vehicle plug in type fuse.
Attention: Replace the fuse by the same type. Using fuses with higher current values means in worst case a burned down system, if an electric
internal short circuit occurs!
8.5 Serial RS232 interface connector
The serial RS232 D-SUB socket is placed on the control panel in the battery box.
Only data receive and send line, signal ground line and shielding are connected by the interface
cable. This means no hardware control (RTS, CTS, ....) for the data flow is supported.
The pin connections (scheme see table below) at the 9 pole D-SUB connector of the interface
cable comply to the RS232C interface standard, used in almost every personal computer, laptop or palmtop. Should the communication be impossible even after correct setting of the
interface parameter and the right serial port chosen, check the interface description of your
computer manual. It might be necessary to exchange the RxD and TxD line at the D-SUB connector.
If you have a computer with 25 pole DSUB serial interface connector, a ready-made adapter to
the 9 pole DSUB connector of the interface cable can be purchased in computer trade shops or
from us.

8.6 Trouble shooting
No „188“ value displayed after power on
Prove connection between battery clamps and control panel connector for
intermittent cable wires. Are the connector/socket contacts deformed or corroded? Check the main fuse in the battery box. Control the battery voltage –
are 11,3 Volt present at the connectors when connecting the battery?
If you are not successful, you have to send us the system back for repair.
„188” does not disappear after power on
Send us the system back for repair.
„188“ flashes after power on continuously
Reason is probably an old or defective battery, which lost its energy storing capacity. Retry it
with a new battery. If you do not succeed contact us.
No speed value appears during vehicle detection
Has the viasis „free sight“ to the vehicles? Is the viasis straightened correctly (chapter 5
foll.)?
Are other high frequency wave radiating installations like high voltage lines, radar or radio
antennas in the near surrounding?
Is the minimal or maximal displayed speed set correctly (see chapter 6.3.4.2)?
Is the Led display deactivated in the actual valid parameter set (see chapter 6.3.2.1)?
Is the measurement time limited in the time schedule of the currently valid parameter set (see
also chapters 6.3.2 foll.).
Has the sensitivity of the radar been reduced (see chapter 6.3.7)?
If you don’t succeed contact our technical support first.
Car speedometer and display value are not equal
Car speedometers are not calibrated and show a remarkably higher speed than the real physical speed of a vehicle. To check the accuracy of the measured speed no car speedometer can
be used, except it was calibrated by the manufacturer (what is not done for serial cars).
An exact check of the accuracy must be made with a calibrated reference system (with radar,
laser, infrared or other optical methods) or a police car with calibrated speedometer.
If you have anyhow the impression that the displayed speed value is too low read chapter
5.1, 5.2 and 7.2 first.
If you don’t succeed contact our technical support first.

Unmotivated speed values are displayed
Are moving objects in the range of the detector, like crossing traffic, moving branches of
trees, birds, bicycles, pedestrians and so on?
If you don’t find any causes for the malfunction, contact us and send the system back.
The numeric LED display shows characters, which are not numbers
The system has an internal defect, contact us and send it back for repair.
8.7 Transport damages
Packing wrap damaged:
Unpack in presence of the delivering transport driver and let him confirm possible
damages of the display system on the delivery notes.
Packing wrap all right, packing contents damaged:
Inform the hauler immediately and demand for an inventory of the damaged display system, if
possible tell the transport driver to note the damage.
Important: Under all circumstances, to avoid the loss of compensation through the transport
insurance or from the hauler, inform the hauler within 24 hours. The delivered systems have
to remain in the same condition until the examination by the insurance took place.
8.8 Sending back/transport preparation/disposal
Before you send the system for repair contact our support. Sometimes systems do not operate
due to parameter settings or other reasons, often we may also offer a less expensive transport
way. Send parcels with „receiver pays cargo fees“ are not accepted.
Error description:
For a faster treatment of your repair, please write us a short error description and
name us a contact person for possible questions of our side.
Packing wrap:
In order to lessen the risk of transport damages, the system should be send generally
only in a complete original packing set. Every wrapping is usually used for maximal
two ways. Although the cardboards may lose their mechanical stability, the foamed
plastic bodies can be used more often. If you cannot store the packing material we
are ready to take it back.
If the original packing set is fully or partly lost, the empty packing set can be ordered from us
(only complete).
Take-back and disposal of old systems:
We take back and dispose our systems free of cost. We disassemble the systems,
sort the parts and materials, which are recycled or if possible reused. Send parcels
with „receiver pays cargo fees“ are not accepted. Please mark the systems clearly
‘for disposal’.
