CHAPTER 2
Overview
This chapter provides an overview of the APCC and its additional components. The chapter also
describes the contents of a product shipment.
Access Point Controller Card (APCC)
The Sensys Networks VDS240 Wireless Vehicle Detection
System detects the presence and movement of vehicles with
magneto-resistive sensors mounted in the pavement.
Wireless sensors continuously transmit detection data to
access points that collect and forward data to remote traffic
management systems or local traffic signal controllers such
as the CalTrans Type 170, Type 2070 ATC and NEMA TS-1
and TS-2 controllers.
The Sensys Networks Access Point Controller Card (APCC),
is a second generation controller card that maintains low
power consumption, supports multiple radios, and allows
for additional communication and processing power. The
APCC, which is compatible with all of Sensys Networks
VDS240 Wireless Vehicle Detection System products,
receives and processes data from the sensors. The APCC
then relays the sensor detection data to a roadside traffic
controller or remote server traffic management system.
Sensys Networks, Inc. - 9 -
Access Point Controller Card Installation Guide Overview
Contact Closure Expansion Card
Additional capacity (to handle more sensors or controller channels) is provided by a contact closure
expansion card (EX card). EX cards use the same form factor as CC cards and are daisy-chained to
a CC card by front-panel RJ45 jacks or backplane connectors. Up to 63 EX cards can be used per
CC card.
Types of APCC Configurations
The APCC single-slot configuration consists of dual APCC radio ports, Sensys Networks Expansion
(EX) port, and contact closure interface via backplane to a traffic controller. It also has dual USB
2.0 full speed host ports and 10/100Base-T network access. The APCC dual-slot configuration adds
an SD memory card, real-time battery-backed clock, dual serial (DB9) interface, and an optional
second serial port or built in cellular modem.
APCC System
The minimum APCC system consists of an APCC and one SPP radio. The system can also consist of
multiple SPP radios and an isolator that offers electrical isolation up to 1500V, surge protection up
to 1500V, and AC power cross protection.
Figure 2-1: APPC system configuration
APCC Serial Port Protocol (SPP) Digital Radio
The APCC, along with the SPP, maintains two-way wireless links to an
installation’s sensors and repeaters, establishes overall time
synchronization, and transmits configuration commands and message
acknowledgements.

CHAPTER 3
APCC Installation Considerations
This chapter provides the installation considerations for the APCC. Prior to installing an APCC
ensure that the following aspects have been considered in the site design.
1. Identify the devices that will be used with the APCC.
2. Determine the configuration of the APCC.
3. Determine the number of available slots in the traffic controller's detector shelf
and which contact closures are required.
4. Develop the sensor-to-contact closure card mappings.
Identifying the SPP, Access Points and Sensors
SPP
Each APCC must connect to an SPP. This connection supplies power to the an SPP and passes
command and configuration data to/from the APCC. There is a one-to-one relationship between
access points and master cards in a network.
Determine the location of the SPP relative to the cabinet that will hold the APCC card. The Cat5
cable that connects to the SPP to the APCC, via an Isolator, must meet standard length limitations
for RS422 communication .
Sensys Networks, Inc. - 15 -
Access Point Controller Card Installation Guide APCC Installation Considerations
Access Points
Each APCC must connect to an access point. This connection supplies power to the access point and
passes command and configuration data to the master card. There is a one-to-one relationship
between access points and master cards in a network.
Determine the location of the access point relative to the cabinet that will hold the APCC. The cable
that connects to the access point to the APCC must meet standard length limitations for Ethernet
over CAT5 (or better) cable. (See the Installation Procedures chapter for more information.)
Note: The APCC is are never directly connected to a access point. EX cards are daisy-chained
together with the APCC at the head-end of the chain.
Wireless Sensors
Each channel of an APCC interfaces a designated set of sensors to a designated contact closure.
Ensure information describing which sensor (or sensors) will actuate a given APCC is available.
Note: Wireless sensor have a unique identifier know as the SensorID. Use this identifier to
refer to sensors in design notes and plans.
Determining the Device Configuration
Configuration of an APCC is based on the following design decisions:
•The number of APCC channels enabled
•The operating mode (pulse or presence) of each channel
•The use of and settings for any optional elements that modify the behavior of channels
operating in presence mode
•The channel status communication method (LED-only or LED with audible tone) used by
each channel
Refer to the Sensys Networks VDS240 Wireless Vehicle System Reference Guide for more
information of the topics above.
Configuration Worksheet
Each APCC supports up to four channels that are separately configured. Design decisions can be
captured in a Channel Configuration Worksheet such as the one shown below. (Note: default
values are shown in bold.)

Sensys Networks, Inc. - 17 -
Access Point Controller Card Installation Guide APCC Installation Considerations
Determining Slots and Contact Closures
Configuration of contact closure cards depends on (i) the availability of open slots on the controller
backplane and (ii) the use of any predefined functions or phases for each slot – such as in the case
of a standard CalTrans 322 shelf, where one contact closure card and three contact closure EX
cards are required (one card per phase). Typically, a site survey of the traffic controller is required.
Shelf and slot information from the controller are used to create an identifier, known as the Card
ID, that uniquely defines an APCC in the network. (See the Installation Procedures chapter for
more information on setting the Card ID.)
Mapping Wireless Sensors to Contact Closures
The final installation consideration for for contact closure cards are the assignment of sensors to
specific channels.
The four channels represent independent contact closures which, in turn, are actuated by the
vehicle detection events transmitted by a defined group of wireless sensors. Each sensor may be
associated with zero or one Card ID / Channel combinations.
Up to 15 wireless sensors can be associated with the same card/channel, in which case the sensors
are logically “OR-ed” together – meaning that if any sensor on the channel detects a vehicle, the
corresponding contact closes.
The sensor-to-contact closure channel mappings are stored in a sensor database that resides in
memory. The sensor-to-contact closure channel mappings are maintained with TrafficDot, the
Sensys Networks system management application.
Defining the channel mappings is aided by the use of a Channel Mapping Worksheet such as the
one shown below.
Sensor-to-Channel Mapping Worksheet

Access Point Controller Card Installation Guide APCC Installation Considerations
Notes
1. The worksheet assumes one sensor per row. Use as many rows as necessary to
assign all necessary sensors to channels.
2. Do not duplicate Sensor ID values. (A wireless sensor may only be assigned
once.)
3. The sample data above depicts representative Card ID values. Since these values
are rarely known prior to field installation, substitute a place-holder value so
that the installer will understand how the wireless sensors are allocated to the
channels.
4. Values for Channel Extension and Location are optional.

SPP Installation Considerations
This chapter provides the installation considerations for the SPP. Prior to installing the SPP, ensure
that the following aspects have been considered in the site design.
•Powering the SPP
•Collecting Data From the
•Determining the Location of the SPP
Each consideration is discussed below. In addition, refer to the Sensys Wireless Vehicle Detection
System Reference Guide, Design Guidelines for Freeway Applications, and Design Guidelines for
Intersection Applications for more information.
Powering the SPP
The overall network design determines how the access point is powered; two general models are
supported:
•Acquiring power directly from a traffic controller cabinet
•Acquiring power from a traffic controller using optional isolator
Acquiring Power From a Traffic Controller
An SPP can be directly interfaced to a traffic signal controller through an APCC. When this is the
case, power to the SPP is drawn from the traffic controller as shown in the following figure.

Acquiring Power Form Traffic Controller Using an Isolator
An optional isolator can be used when acquiring power from the traffic controller as shown in
following figure.
Figure 3.2 – SPP radio powered from a traffic controller
Sensys Networks, Inc. - 21 -
Access Point Controller Card Installation Guide SPP Installation Considerations
Voltages
Access points use the following voltages drawn from one of the following sources:
•36VDC – 58VDC (48VDC nominal) - typically supplied from a nearby traffic controller
cabinet or power pole
•10VDC – 20 VDC (12 VDC nominal) - typically supplied from a solar panel
Cabling
Standard Ethernet compatible, outdoor rated, 4-pair CAT5 or better cable is required. The
maximum cable length is 100 meters (328 feet). The cable should be terminated with RJ45
connectors according to the TIA/EIA 568-B specification when it is installed.
Note: The outside diameter of the cable is an important attribute. The cable's OD is used to select the
proper bushing for the access point's bulk head connector on access points manufactured after May
2010.
Collecting Data From the APCC
The APCC automatically collect detection events and, depending on the network design, forward
them to upstream traffic information systems and management servers via an IP network
connection. An on-board Ethernet network interface facilitates this. In situations where a wired
network connection is not available, a modem supporting either GSM-based or CDMA-based
cellular services may be added.
The following connection models are supported for IP communications:
•Connection via a wired network path – for example, bench configuration prior to
installation, field access based on patching a technician's laptop to the access point via an
Ethernet cable, or an available wide area network connection.
•Connection via a wireless network path – for example, using GSM cellular networks
(EDGE/GPRS data services) or CDMA cellular networks (1xRTT data services).
Additionally, event data may be forwarded to a local traffic signal controller via an APCC. This
interface converts event data to the signal pattern required by the traffic controller.
Determining the Location of the SPP
The physical location of the SPP is the primary determinant of communications quality and, as
such, the network's overall usefulness and reliability. Selecting a location involves several factors
(including other local RF transmissions) that may make pre-assigned locations problematic.
Sensys Networks, Inc. - 22 -
Access Point Controller Card Installation Guide SPP Installation Considerations
Optimal Location Criteria
Optimal locations for SPP digital radios meet all of the following criteria:
•are high enough to promote high quality RF communications on a sustained basis
•allow a line-of-sight path to the APCC, (optional) isolator, and wireless sensors
•are within recommended distances for the APCC, (optional) isolator, and wireless sensors
•allow the SPP to be mounted with its bulkhead connector and cellular antenna (if
applicable) pointed toward the ground
•allow the SPP to face the APCC, (optional) isolator, and wireless sensors
•are within specified cable length limits
•do not submit the SPP to avoidable vibration, shaking or movement
•are reasonably accessible to field support personnel

Determining the Card ID and Setting it via Circuit-board Dip
Switches SW1 and SW2
APCC and EX cards are addressed via a value known as the Card ID. A Card ID must be unique to
the network and is required for communication between the APCC and the EX cards.
Card ID values are expressed as: [ shelf number ] ― [ slot number ].
Both shelf-number and slot-number must be determined to create a Card ID.
Some traffic controllers designate the card address, while others (typically older models) do not. In
the latter case, the installer assigns the Card ID ensuring that it is unique to the network.
Follow the procedures in this section for each contact closure card to be installed.

Access Point Controller Card Installation Guide APCC Installation Procedures
Factory Default Card ID
Card IDs are implemented on Sensys Networks contact closure cards via two dip switches found on
the side of the card. In this guide, the switches – named SW1 and SW2 respectively – are referred
as circuit-board dip switches to differentiate them from other dip switches on the front-panel of
contact closure cards.
A default Card ID of “03-15” is assigned at the factory and is shown in the figure below. (Note that
on the card, switches SW1 and SW2 are not as close to one another as shown in the figure.)
Figure 5.1 – Default Card ID (all dips down)
Before proceeding, ensure that switches SW1 and SW2 are set as in the figure above and,
additionally, that all front-panel switches are in the right-hand position.
Querying the Backplane for an Assigned Address
The APCC support an operating mode (called X mode) that queries the traffic controller backplane
for an address. Because it can be difficult to determine from visual inspection if the backplane
dictates card addresses, the standard practice is to use X mode to see if this is the case.
X mode uses the four front-panel channel LEDs to visually indicate the backplane address assigned
by the controller (if any). (Refer to Appendix 1 for a figure that depicts how the channel LEDs are
used.)
Follow these steps to use X mode to query the controller for a card address:
1. Verify that the APCC is set to its default Card ID and that all front-panel
switches are in the right-hand position.
2. Reset the APCC by pressing the master reset button (located on front-panel next
to channel LEDs) or removing the unit from the cabinet and re-inserting it.
3. Observe the front-panel channel LEDs. Match the pattern of lighted LEDs with
the figure in Appendix 1.
The address value that matches the LED display pattern (from Appendix 1) is the slot
number component of the Card ID.
Note: After the cabinet backplane is queried for an address, be sure to take the APCC card out
of X-mode by setting front-panel dip switch 2 to the right, and resetting the card.
Sensys Networks, Inc. - 25 -
Access Point Controller Card Installation Guide APCC Installation Procedures
Setting the Slot-Number With Circuit-board Dip Switch SW2
Circuit-board dip switch SW2 implements the slot number component of the Card ID. Set switch
SW2 to match the value derived from the figure in Appendix 1 subject to the exception noted below.
Exception
In cases where the controller does not assign an address, the installer will see a front-panel
channel LED display pattern indicating an address of 15 (all LEDs lighted). This address can be
used for the first contact closure card installed. However, subsequent cards must be given a
different address ― arbitrarily assigned by the installer. Any value between 0 and 15 may be
used; remember that Card IDs must be unique for the network.
Refer to Appendix 3 for a figure that illustrates how to set switch SW2 to values between 0 and 15.
Setting the Shelf-Number With Circuit-board Dip Switch SW1
Circuit-board dip switch SW1 implements the shelf number component of the Card ID. Shelf
numbers are assigned by the installer after visually inspecting the cabinet.
The convention is to consider the top-most shelf in the card rack as shelf zero and to increment the
shelf number by one for each shelf below the top-most shelf. For example, the bottom shelf in a
cabinet of four shelves would be considered shelf three.
Set circuit-board dip switch SW1 to the shelf number using the two left-most switches. Refer to
Appendix 2 for a figure that illustrates how to set switch SW1 to values between 0 and 3.
Determining the Controller Type and Setting it via Circuit-
board Dip Switch SW1
At the factory, contact closure cards are set for use with Type 170, Type 2070 (without status
relays), or NEMA TS1 traffic controllers. This setting is made with switch three of circuit-board dip
switch SW1.
Verify the controller type and set dip three of circuit-board dip switch SW1 as needed. Use the
figure in Appendix 2 as a guide for setting switch 3 of SW1 to the proper value.
Connecting the Cables to Each Device

•Double-sided sticky tape – attaches AccessBox to flat surface inside the controller cabinet
Step-by-Step Procedures
The square surface mounting ball plate can be installed on any available vertical surface sufficient
to support the SPP including poles, walls or beams. This section provides procedures for pole
installation; considerations for wall or beam mounting follow this section.
Installing the Mounting Plate on Poles
When attaching the square surface mounting ball plate to a pole, the clamp band is used to secure
the ball plate to the pole. (See Appendix 1 for more information about working with the clamp
band.)
Follow these steps to perform the installation:
1. Use the measuring tape to determine the circumference of the pole that will hold the
ball plate.
2. Subtract four inches from the measured circumference and cut the band to that
length. Cut the band through the center of the nearest round hole.
3. Feed the clamp band through the square ball plate using the custom clamp holes (see
figures below) until the square ball plate is at the center of the band. Attach the
fastener to one end of the band by diagonally inserting the end.

CHAPTER 7
Configuration
This chapter explains how to configure channels and and other operating elements of contact
closure cards in the APCC and EX cards.
Note: Prior to configuring channels, ensure that each contact closure card has been given a unique
Card ID. Refer to the Determining the Card ID section in the Installation Considerations chapter
for more information.
Overview
Each channel of an APCC or EX card is configured separately. Configuring a channel consists of the
following activities:
•Enabling (or disabling) the channel
•Specifying the channel mode
•Setting a presence mode modifier (optional)
•Specifying the type of communication used to disclose channel status
Additionally, after channel configuration is completed, TrafficDot is used to define the sensor-to-
channel mappings stored on the APCC.
After all configuration work is complete, including definition of sensor-to-channel mapping entries
for all channels, Sensys Networks recommends verifying the operation of each channel using the
front-panel channel LEDs.
Sensys Networks, Inc. - 32 -
Access Point Controller Card Installation Guide Configuration
Configuration Methods
Configuration occurs through two mutually exclusive choices: (i) the card's front-panel interface or
(ii) with TrafficDot, the system management application from Sensys Networks. This chapter
includes the following sections:
•Configuring channels with the front-panel interface
•Starting TrafficDot and Connecting to an APCC
•Configuring channels with TrafficDot
•Defining the sensor-to-channel mappings
•Exiting TrafficDot
Configuring Channels With the Front-Panel Interface
After completing the configuration of all channels, continue setting up the APCC by starting the
TrafficDot software utility and defining the sensor-to-channel mappings.
Note: If the APCC is configured with TrafficDot, this section can be ignored.
General Procedure
The general procedure for configuring channels via the front-panel is provided below. Examples of
specific configuration activities are included in the following sections. The steps are as follows:
1. Select a channel.
2. Move dip switches (as required) to represent the desired settings.
3. Press the MASTER RESET button on the card front-panel and hold it down for a
minimum of five seconds.

Saving the Configuration
After the MASTER RESET button is pressed, the LINK LED flashes. When the flashing stops,
the settings have been stored in flash memory.
The sections below give examples of setting specific configurations via the front-panel interface.
The procedures may be performed in any order or combination.
Enabling / Disabling a Channel
APCC and EX cards ship with channels one and two enabled. Sensys Networks recommends
explicitly disabling all unused channels.
Follow these steps to enable or disable a channel.
1. Position front-panel dip switch 8 to the left to enable (to the right to disable) the
channel.
Figure 7.2 – Enabling (Disabling) a channel with front-panel dip switch 8
2. Press the Enter button for five seconds to save the configuration to flash
memory or continue with other configuration activities described in this section.
Sensys Networks, Inc. - 34 -
Access Point Controller Card Installation Guide Configuration
Specifying the Channel Mode
Contact closure cards operate in either pulse or presence mode. (Refer to the Sensys Networks
VDS240 Wireless Vehicle Detection System Reference Guide for information about the operating
modes.)
Follow these steps to specify the operating mode of the channel.
1. Position front-panel dip switch 7 to the left to select presence mode or to the
right to select pulse mode.
Figure 7.3 – Selecting the channel operating mode with front-panel switch 7
2. Press the Enter button for five seconds to save the configuration to flash
memory or continue with other configuration activities described in this section.
Setting a Presence Mode Modifier (Optional)
Channels operating in presence mode may use a modifier to delay the onset of or extend the
duration of a contact closure. The modifier type and scope is specified using front-panel dip
switches five and six together. (Refer to the Sensys Networks VDS240 Wireless Vehicle Detection
System Reference Guide for more information.)
Using Delay and Extension
When Delay or Extension are specified, the rotary dial is used to articulate the numeric value
associated with the parameter.
When Delay is specified, the value set on the rotary dial is taken directly. This allows the 16-
step rotary switch to represent values from 0 to 15.
When Delay+16 is specified, the value set on the rotary dial is incremented by 16. This allows
the 16-step rotary switch to represent values from 16 to 31.
When Extension (EXTN / 2) is specified, the value set on the rotary dial is divided by 2. This
allows the 16-step rotary switch to represent values from 0 to 7.5 in ½ step increments.
Specify a contact closure delay or extension for channels operating in presence mode by following
these steps:
1. Position front-panel dip switches 5 and 6 and the front-panel rotary switch to
reflect the desired modifier and scope value. Use the figure below as a guide.
Sensys Networks, Inc. - 35 -
Access Point Controller Card Installation Guide Configuration
Figure 7.4 – Setting a delay or extension with front-panel dip switches 5 and 6 (Rotary switch not shown)
Note: This step is optional; set both dips to right-hand position to disable the feature.
Additionally, front-panel switches 5 and 6 are ignored for channels operating in pulse
mode.
2. Press the Enter button for five seconds to save the configuration to flash
memory or continue with other configuration activities described in this section.
Specifying the Type of Communication Used by the Channel Status Monitor
Contact closure cards indicate the status of each channel via the front-panel LEDs. The state of an
LED corresponds directly to the channel state. When the LED is on, the channel relay is closed
indicating a call. When the LED is not on, the channel relay is open.
Additionally, a contact closure card can be set such that closed channel relays activate an audible
tone (buzzer) as well as the front-panel LED for the channel. The audible channel status tone is set
via front-panel dip switch one as follows:
1. Position front-panel dip switch 1 to enable or disable the audible channel status
monitor. Use the figure below as a guide.
Figure 7.5 – Setting the channel monitor buzzer with front-panel dip switch 1

Starting TrafficDot and Connecting to an APCC
TrafficDot is a small, self-installing program that provides a graphical user interface (GUI) to the
components of a Sensys Networks Wireless Vehicle Detection network. It is used to optionally
configure contact closure cards and to define the sensor-to-channel mappings.
TrafficDot requires an IP network connection to the access point. Typically, when configuring
contact closure cards, this connection is made by cabling a laptop to the “ACCESS” port of the
AccessBox. (See the section Cabling Summary for additional information.)
See also the Sensys Networks VDS240 Wireless Vehicle Detection System Reference Guide for a
more discussion of using TrafficDot with the Sensys Networks Wireless Vehicle Detection System.
