1 INTRODUCTION
The Wireless Space Count system facilitates accurate measurement on occupancy of individual parking
spaces in car parks, and on-street parking spaces. This information can be used to guide traffic to free
parking spaces but can also be used for on-street parking enforcement and overstay detection. For on-
street enforcement the number of occupied parking spaces can be compared with the number of
payments realized by the pay station. For overstay detection the system alerts instantly a parking officer
to the presence of nearby overstaying vehicles. Based on this information you can exactly determine
which space to enforce.
1.1 PRODUCT DESCRIPTION SENSIT DATACOLLECTOR
The actual status (occupancy) of the SENSIT is collected by one or more SENSIT DATACOLLECTOR.
The SENSIT DATACOLLECTOR is the interface between the SENSIT and the host system The SENSIT
DATACOLLECTOR transmits status information about the sensors to the host system through RS232 or
Ethernet communication. Over RS232 the SENSIT DATACOLLECTOR communicates via a serial
connection to the host. Over TCP/IP the SENSIT DATACOLLECTOR communicates directly on your
LAN network. The TCP/IP communication allows you to decide on direct communication or to make use
of a database application.
For a parking site you need at least one SENSIT DATACOLLECTOR and a SENSIT per parking bay.
One SENSIT DATACOLLECTOR is required per 100 parking bays. All SENSIT DATACOLLECTOR
must be separated as far as possible from each other, preferably with a 200+ network at every corner of
the site a SENSIT DATACOLLECTOR.
Note: This manual is not intended for the end user, the SENSIT DATACOLLECTOR shall be installed
by a professional. The case is preventing to remove the antenna so that the end user cannot
and shall not detach it from the device.

2 INSTALLATION SENSIT DATACOLLECTOR
2.1 SAFETY PRECAUTIONS
The following safety precautions should be observed during normal use, service and repair.
• The SENSIT DATACOLLECTOR may only be installed and serviced by qualified service personnel.
• Disconnect the power supply before removing or installing any parts.
• To be sure of safety, do not modify or add anything to the SENSIT DATACOLLECTOR other than
mentioned in this manual or indicated by NEDAP N.V.
2.2 DIMENSIONS AND MOUNTING
The SENSIT DATACOLLECTOR can be mounted in a central enclosure, however please ensure that the
enclosure is not made of metal. The SENSIT DATACOLLECTOR is featured with RF communication
with the SENSIT. The material used for the enclosure should be transparent for RF signals.
Locate an appropriate position for the SENSIT DATACOLLECTOR, preferable on a location where power
and communication is available (normally around the gate). Use the four keyholes to mount the SENSIT
DATACOLLECTOR in the enclosure.
See Figure 1 below for details about the dimensions (in mm) and the locations of the mounting positions.

2.3 CONFIGURATION OF SENSIT DATACOLLECTOR
Once the SENSIT DATACOLLECTOR are installed ensure that one remains the master and the other
SENSIT DATACOLLECTOR act as slaves. Verify communication between the server and the SENSIT
DATACOLLECTOR.
The cover can be removed to set up TCP/IP or RS232 communication and view the LED indicators.
Open all four screws on the bottom of the device to unlock the cover. Once the service cover is
unlocked, lift it off. Ensure to push the antenna down. Unscrew the antenna from the PCB to fully
remove the cover.

Note: Ensure to push the antenna down before removing the cover. The antenna can be screwed off.
2.4 COMMUNICATION
The SENSIT DATACOLLECTOR has on-board TCP/IP and RS232 communication. Default the SENSIT
DATACOLLECTOR is set to TCP/IP communication. The same events and commands can be received
and transmitted by RS232 as well as TCP/IP.
2.4.1 TCP/IP CONNECTION
The SENSIT DATACOLLECTOR has on-board TCP/IP communication. Default the jumpers (K9 and
K10) are set to XPORT.

Note 2: Enable the on-board TCP/IP interface by setting Jumper K9 and K10 to XPORT. See Figure 4
for details.
2.4.1.1 XPORT configuration
SENSIT DATACOLLECTOR is featured with a Lantronix XPORT (type Xport-03) with an embedded
Ethernet device server with a full TCP/IP protocol stack. You can configure the XPORT with e.g. a
static IP-address using the Lantronix Device Installer. The Device Installer is a Windows-based GUI
application that provides an easy way to install and configure specific Lantronix device server products.
Below the link to the Device Installer download area of the Lantronix website. www.lantronix.com/device-
networking/utilities-tools/device-installer.html
The Data Collection is featured with a node name e.g. “NODE1059” also mentioned on the outside of the
housing. You can approach the SENSIT DATACOLLECTOR by this name with a DHCP server and DNS.
When you have given the SENSIT DATACOLLECTOR a fixed IP address, you can reach the SENSIT
DATACOLLECTOR via this fixed IP address. As an example; For "NODE1059 10001" you can fill in
"10.66.5.222 10001".

3 DATA CONFIGURATION
The Data format of messages from the SENSIT and the SENSIT DATACOLLECTOR are the same
whether TCP/IP or RS232 communication is applied. The SENSIT is default already configured and for
most installations this should be all right. The below mentioned command messages are therefore only
required if you want to change specific settings.
3.1 DATA FORMAT
The data format is fixed:
Baud rate: 115200
Data bits: 8
Parity: None
Stop bits: 1
3.2 COMMAND MESSAGE FORMAT TO THE NODE(S)
Commands messages that are sent to the SENSIT should be sent in the following format:
XXXX0000IIII[DDDD][DDDD]....
XXXX Node ID (FFFF is broadcast)
0000 Message number; always four zeros
IIII Instruction code
DDDD Optional data word 16 bit
The SENSIT DATACOLLECTOR software replaces the 0000 message number with an automatic
increment message number between 0080 and 00FF. When your own interface software is making the
message number it is highly recommended to use the same range.
3.3 DATA MESSAGE FORMAT FROM THE NODE(S)
The data message format from the SENSIT is similar to the command message format, except YYYY
are not four zeros but an internal message number. The node adds an internal message number to a
created event message, in the range from 0000 to 007F.
XXXXYYYYIIII[DDDD][DDDD]....
XXXX Node ID, FFFF is broadcast
YYYY Internal message number
IIII Instruction
DDDD optional data word 16 bit
The four MSB bits of the Instruction word are the (not) acknowledge and type of data flags?
CXXX The data field contains an ASCII string (example command 00CA)
4XXX Data from a node (always)
5XXX Error in instruction
6XXX Unknown instruction
More detailed information about all the commands can be found in the Wireless Space Count Install
Guide.

4 PROJECT SUPPORT
Based on our thorough project analysis including configuration and installation advice we can offer the
customer the best AVI solution.
4.1 SITE SURVEY & INSTALLATION ADVICE
This will consist of an engineer visiting the site to visually inspect and analyze the location. We will then
carry out calculations and provide you with detailed configuration and installation advice for the Wireless
Space Count equipment for a specific project.
4.2 ON-SITE CERTIFICATION
An engineer will visit the site to inspect the installation of the equipment on reliable and accurate
detection. Nedap engineers are not involved in installation (wiring) of any equipment. The installation
must be completed before the engineer arrives on-site. We will ensure that the operation confirms our
commissioning requirements, only on condition of prior given installation advice.

harmful interference in a residential installation. This equipment generates uses and can radiate radio
frequent energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does not cause harmful interference to radio or television reception, which can be determine
by turning the equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
- Reorient or relocate some node
- Connect the equipment into an outlet on a circuit different from that to which the SENSIT
DATACOLLECTOR is connected.
- Consult the dealer or an experienced radio/TV technician for help.
