  • Page 9: Overview

    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.

    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.

    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.

    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. Sensys Networks, Inc.

  • Page 21: Acquiring Power Form Traffic Controller Using An Isolator

    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 - 21 - Sensys Networks, Inc.

  • Page 22: Voltages

    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. - 22 - Sensys Networks, Inc.

  • Page 23: Optimal Location Criteria

    • 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 - 23 - Sensys Networks, Inc.

  • Page 24: Apcc Installation Procedures

    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. - 24 - Sensys Networks, Inc.

  • Page 25: Factory Default Card Id

    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.
