This guide provides information and procedures for installing Sensys Networks Radio (SPP) and FlexRadio Cabinet in conjunction with the Sensys Networks VDS240 wireless vehicle detection system. This document is intended to be used by Sensys Networks customers, consultants, partners, dealers, and those who are interested in the application of wireless communication technology to the challenges of traffic detection, management, and control. -
Page 9: Chapter 2: Overview
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 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. -

FlexControl. Types of FlexControl Configurations The FlexControl consists of dual radio ports, Sensys Networks Expansion (EX) port, and dual USB 2.0 full speed host ports and 10/100Base-T network access. The FlexControl also contains contact closure interface via backplane to a traffic controller. -

Page 22: Radio (Spp) Radio Bulkhead Connector
Two cable bushings are included; choose one to fit the outside diameter of the Ethernet cable being connected to the Radio (SPP). Additionally, a spare gasket is included; use the gasket only if the factory installed gasket is lost or visibly damaged. Radio (SPP) / FlexRadio Cabinet 15 Sensys Networks, Inc. Installation Guide... -
Page 23: Step-By-Step Procedures
2. Carefully inspect the factory installed gasket seated on the bulkhead connector. Ensure the gasket is seated smoothly and uniformly on the connector with the ridged edge of the gasket facing outward. Radio (SPP) / FlexRadio Cabinet 16 Sensys Networks, Inc. Installation Guide... - Page 24 Replace the gasket if it does not uniformly seat or shows signs of fatigue or wear. (When replacing a Radio (SPP), always use a new gasket.) Use gaskets from Sensys Networks only. Never substitute a different gasket; doing so exposes the device to environmental risk and voids the product warranty.
