Sensors (VSN240-F, VSN240-T, VSN240-S, VSN240-M, VSN240-F-2,
VSN240-T-2)
Repeaters (RP240-BH-2, RP240-BH-LL-2, FLEX-RP-B-2, FLEX-RP-B-LL-2)
Lithium batteries are widely used in electronic products because they contain more
energy per unit -weight than conventional batteries. However, the same properties that
deliver high energy density also contribute to potential hazards if the batteries are
damaged. Improper use or handling of the batteries may result in leakage or release of
battery contents, explosion, or fire.
Following are the recommendations of the battery manufacturer for proper use and
handling of batteries in the Sensys Networks devices mentioned above:
DO NOT charge or attempt to recharge the batteries (they are NOT
rechargeable)
DO NOT crush or puncture batteries
DO NOT short-circuit the batteries
DO NOT force over-discharge of the batteries
DO NOT incinerate or expose batteries to excessive heating
DO NOT expose battery contents to water
DO dispose of batteries and devices containing batteries in accordance with
local regulations

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 the APCC
that collects and forwards 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.
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
APCC cards and are daisy-chained to a CC interface on the APCC on the front-
panel RJ45 jacks or backplane connectors. Up to 63 EX cards can be used per
APCC card.

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 (refer to Identifying the SPP
and Sensors).
2. Determine the configuration of the APCC (refer to Determining the Device
Configuration).
3. Determine the number of available slots in the traffic controller's detector
shelf and which contact closures are required (refer to Determining Slots and
Contact Closures).
4. Develop the sensor-to-contact closure card mappings (refer to Mapping Wireless
Sensors to Contact Closures).
Identifying the SPP and Sensors
SPP
Each APCC must connect to an SPP. This connection supplies power to the SPP
and passes command and configuration data to/from the APCC. There is a one-to-
one relationship between the APCC 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 (2,000 ft with isolator) for RS422
communication.
Chapter 3

Installation Guide Sensys Networks, Inc.
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 sensors have a unique identifier known as the Sensor ID. 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) used by each channel
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.

Notes
1. Contact closure cards are addressed by the Card ID, a value dictated by the
controller or supplied by the installer.
2. Complete one worksheet for each channel.
3. Channel Holdover Setting should not be used; set it to zero.
4. The items listed in the section Other Information are not part of APCC
configuration. They are relevant to other aspects of installing and operating
the APCC.
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.
IMPORTANT!
If using an APCC with an I/O board, it is essential that there is an empty slot directly to the left of
the APCC.

Mapping Wireless Sensors to Contact Closures
The final installation consideration 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 within TrafficDOT.
Defining the channel mappings is aided by the use of a Channel Mapping
Worksheet such as the one shown below.
Table 3. Sensor-to-channel mapping worksheet with sample data
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 APCC
Determining the Location of the SPP
Each consideration is discussed below. In addition, refer to the Sensys Networks
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 SPP 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.
Chapter 4

as shown in following figure.
Figure 4.2. SPP radio powered from a traffic controller
SPP Installation Considerations
Access Points Controller Card (APCC) 15
Sensys Networks, Inc. Installation Guide
Voltages
The APCC uses the following voltages drawn from one of the following sources:
20VDC – 28 VDC (24 VDC nominal) – typically supplied from a nearby traffic
controller cabinet or power pole
10VDC – 16 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 328 feet (100 meters) or 2,000 ft (610
meters) with isolator. The cable should be terminated with RJ45 connectors
according to the TIA/EIA 568-B specification when it is installed.
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
APCC 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.
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 (optional) isolator, wireless sensors, and repeaters
Chapter 4

APCC Installation Procedures
This chapter provides the instructions for installing and cabling an APCC.
Overview
Installation and setup of APCC occurs at the site of the traffic controller and
consists of the following activities:
Determining the Card ID and Setting it via Circuit-board Dip Switches SW1 and SW2
Determining the Controller Type and Setting it via Circuit-board Dip Switch SW1
Connecting the Cables to Each Device
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.

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
following figure.
NOTE:
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 Figure 5.1 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 A: X Mode LED
Displays for Slot Numbers 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 A: X Mode LED Displays for Slot Numbers.
The address value that matches the LED display pattern (from Appendix A) is the
slot number component of the Card ID.
APCC Installation Procedures
Access Points Controller Card (APCC) 19
Sensys Networks, Inc. Installation Guide
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.
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 A
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 C: Circuit-board Dip Switch SW2 Settings 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 B: Circuit-board Dip Switch SW1 Settings 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 B: Circuit-board Dip Switch SW1 Settings as a guide
for setting switch three of SW1 to the proper value.

Configuration
This chapter explains how to configure channels and other operating elements of
contact closure cards in the APCC and EX cards.
N
OTE
:
Prior to configuring channels, ensure that each contact closure card has been given a
unique Card ID. Refer to the Identifying the SPP and Sensors 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.
Chapter 7
36 Access Point Controller Card (APCC)
Installation Guide Sensys Networks, Inc.
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 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.
N
OTE
:
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.
Configuration
Access Point Controller Card (APCC) 37

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.
Chapter 7
38 Access Point Controller Card (APCC)
Installation Guide Sensys Networks, Inc.
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.

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.

Starting TrafficDOT and Connecting to an APCC
TrafficDOT is a configuration manager and monitoring tool for an access point
and all its associated devices (sensors, repeaters, and contact closure cards).
TrafficDOT provides a graphical user interface (GUI) to the network's devices,
settings, and operations. The GUI simplifies both configuration and management
of installations.
TrafficDOT requires an IP network connection to the APCC. When configuring
contact closure cards, the connection is made by cabling a laptop to an APCC or
EX card. (Refer to the section Cabling Summary in Chapter 5 for additional
information.)

Configuring Channel State
Contact closure card channels are independent of one another and are individually
configured. Each channel occupies one of the following states:
Enabled – the channel is operational; Sensor event data collected by the access
point is transmitted to the contact closure card.
Disabled – the channel is not operational. (When a channel is disabled, its
contact closure relay and status relay are continuously open.)
The factory default configuration enable channels one and two. Ensure that any
unused or unavailable channels are disabled.
Configuring Channel Mode
Enabled channels operate in one of the following modes:
Pulse – the contact closure relay pulses for 0.125 seconds each time the leading
edge of a vehicle is detected.
Presence – the contact closure relay remains closed while a vehicle is detected.
The factory default setting is pulse mode.
Chapter 7
44 Access Point Controller Card (APCC)
Installation Guide Sensys Networks, Inc.
Configuring Presence Mode Modifier
The behavior of a channel operating in presence mode may adjusted by applying
one of the following modifiers:
Delay – defers the onset of the contact closure by a specified duration. If a
vehicle moves off of the sensor before the specified delay expires, the contact
does not close. Delay is expressed in seconds from zero to 31.
Extension – increases the duration of the contact closure by a specified
increment. Extension is expressed in half-seconds from zero t0 7.5.
The modifiers do not apply to channels operating in pulse mode.
Configuring Channel Holdover Duration
The Channel Holderover parameter allows an extension to the channel holdover
duration when it is activated by the events from a particular sensor. Values from
0.0 to 0.75 are available for selection.
Defining Sensor-to-Channel Mappings
To map sensors to an APCC or EX card, perform the following steps:
1. Select a sensor from the image map.
2. Open the Card Addresses window by clicking the Card Addresses tab.
The Extension entry extends the duration of an APCC or EX card on a per-sensor
basis. The Delay entry delays the duration of an APCC or EX card on a per-sensor
basis; these entries are optional.
