CHAPTER 2
Overview
This chapter provides an overview of the A CC 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 oint Controller Card (A CC),
is a second generation controller card that maintains low
power consumption, supports multiple radios, and allows
for additional communication and processing power. The
A CC, which is compatible with all of Sensys Networks
VDS240 Wireless Vehicle Detection System products,
receives and processes data from the sensors. The A CC
then relays the sensor detection data to a roadside traffic
controller or remote server traffic management system.

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 A CC single-slot configuration consists of dual A CC 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 A CC 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 A CC system consists of an A CC and one S radio. The system can also consist of
multiple S radios and an isolator that offers electrical isolation up to 1500V, surge protection up
to 1500V, and AC power cross protection.

CHAPTER 3
APCC Installation Considerations
This chapter provides the installation considerations for the A CC. rior to installing an A CC
ensure that the following aspects have been considered in the site design.
1. Identify the devices that will be used with the A CC.
2. Determine the configuration of the A CC.
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 A CC must connect to an S . This connection supplies power to the an S and passes
command and configuration data to/from the A CC. There is a one-to-one relationship between
access points and master cards in a network.
Determine the location of the S relative to the cabinet that will hold the A CC card. The Cat5
cable that connects to the S to the A CC, 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 A CC 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 A CC. The cable
that connects to the access point to the A CC must meet standard length limitations for Ethernet
over CAT5 (or better) cable. (See the Installation Procedures chapter for more information.)
Note: The A CC is are never directly connected to a access point. EX cards are daisy-chained
together with the A CC at the head-end of the chain.
Wireless Sensors
Each channel of an A CC interfaces a designated set of sensors to a designated contact closure.
Ensure information describing which sensor (or sensors) will actuate a given A CC 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 A CC is based on the following design decisions:
•The number of A CC 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 ireless Vehicle System Reference Guide for more
information of the topics above.
Configuration Worksheet
Each A CC supports up to four channels that are separately configured. Design decisions can be
captured in a Channel Configuration orksheet 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 A CC 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 orksheet such as the
one shown below.

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 S . rior to installing the S , ensure
that the following aspects have been considered in the site design.
•owering the S
•Collecting Data From the
•Determining the Location of the S
Each consideration is discussed below. In addition, refer to the Sensys ireless 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 S can be directly interfaced to a traffic signal controller through an A CC. When this is the
case, power to the S is drawn from the traffic controller as shown in the following figure.
