Warnings

No Safety Switching

Sensys Networks does not allow its equipment to be used for safety applications such

as controlling a mechanical gate or switching a train to avoid a collision.

Lithium Thionyl Chloride Batteries

Sensys Networks uses Lithium Thionyl Chloride batteries in the following products:

Sensors (VSN240-F, VSN240-T, VSN240-S, VSN240-M, VSN240-M-2,

VSN240-F-2, VSN240-T-2)

Repeaters (RP240-BH-2, RP240-BH-LL-2, FLEX-RP-B-2, FLEX-RP-B-LL-2,

FLEX-RPT3-SLR)

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

OTE

Sensys Networks wireless sensors contain no serviceable parts and should never be

disassembled. Installation and removal of sensors from pavement should only be done by

trained personnel and care should be taken to insure that the sensor casing is not punctured

or crushed.

Chapter 2

Overview

This chapter provides an overview of the FlexControl Card (APCC) and

FlexControl Module and its additional components. The chapter also describes

the contents of a product shipment. Unless otherwise noted, the document uses

the term FlexControl to apply equally to the following:

FlexControl Card (APCC)

FlexControl Module

FlexControl

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

FlexControl Card (APCC) and FlexControl Module 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 FlexControl, is a third generation controller card that

maintains low power consumption, supports multiple radios, and allows for

additional communication and processing power. The FlexControl, which is

compatible with all of Sensys Networks VDS240 Wireless Vehicle Detection

System products, receives and processes data from the sensors. The FlexControl

then relays the sensor detection data to a roadside traffic controller or remote

server traffic management system.

Overview

FlexControl Card (APCC) and FlexControl Module 3

Sensys Networks, Inc. Installation Guide

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

FlexControl Cards (APCC) and are daisy-chained to the EX interface on the

FlexControl Card (APCC) or the FlexControl Module. Up to 63 EX cards can be

used per FlexControl Card (APCC) or FlexControl Module.

Types of FlexControl Configurations

The FlexControl Card (APCC) single-slot configuration consists of dual

FlexControl Card (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 FlexControl Module includes dual radio ports, Sensys Networks Expansion

(EX) port, and includes a DIN mount and a bracket mount kit for installation in a

traffic cabinet. It also has dual USB 2.0 full speed host ports, single USB 2.0 full

speed device port, and 10/100Base-T network access.

Figure 2.1. FlexControl Card (APCC) (left) and FlexControl Module (right)

FlexControl System

The minimum FlexControl system consists of a FlexControl and one Radio (SPP).

The system can also consist of multiple Radios (SPP) and an isolator that offers

electrical isolation up to 1500V, surge protection up to 1500V, and AC power cross

protection.

FlexControl comes in two form factors - FlexControl Module, an enclosed box

which mounts to the cabinet via bracket or DIN mount; and FlexControl Card

(APCC), which connects directly to the cabinet rack.

Both versions come with Ethernet and dual USB interfaces, while FlexControl

Module includes additional internal memory, a USB type-B port and terminal

block or barrel power connector options. FlexControl Card (APCC) uniquely comes

standard with contact closure support and optionally offers an expandable SD

memory card slot with dual serial (DB9) interfaces.

Figure 2.3. FlexControl Module system configuration

FlexControl and Serial Port Protocol (SPP) Digital Radio

The FlexControl, along with the Radio (SPP), maintains two-way wireless links to

an installation’s sensors and repeaters, establishes overall time synchronization,

and transmits configuration commands and message acknowledgments.
