The Sensys Networks Access Point (AP) is an intelligent LINUX device used to maintain two-way communications with in-ground wireless sensors, and battery-powered repeaters. Using either wired and/or wireless connections, APs relay data to roadside controllers, remote servers, traffic management systems, or other vehicle detection applications.

Access Points are available in the following configurations:

  • AP240-E: RJ45 port supports Ethernet interface for field configuration and data relay, statistics-processing and VPN functionality; configurable with 48VDC or 12VDC power input via RJ45 port
  • AP240-S: RJ45 port supports simultaneous Ethernet and CC card communications (split via Access Box)
  • AP240-ES: RJ45 port supports simultaneous Ethernet and CC card communications (split via Access Box) combined with data relay, statistics-processing and VPN functionality
  • AP240-EG: RJ45 port supports Ethernet interface for field configuration and data relay, statistics-processing and VPN functionality; configurable with 48VDC or 12VDC power input via RJ45 port with Integrated GPRS cellular data modem for data relay via GSM
  • AP240-ESG: RJ45 port supports simultaneous Ethernet and CC card communications (split via Access Box) combined with data relay, statistics-processing and VPN functionality with Integrated GPRS cellular data modem for data relay via GSM
  • AP240-EC: RJ45 port supports Ethernet interface for field configuration and data relay, statistics-processing and VPN functionality; configurable with 48VDC or 12VDC power input via RJ45 port with Integrated 1xRTT cellular data modem for data relay via CDMA (available for various providers)
  • AP240-ESC: RJ45 port supports simultaneous Ethernet and CC card communications (split via Access Box) combined with data relay, statistics-processing and VPN functionality with Integrated 1xRTT cellular data modem for data relay via CDMA (available for various providers)

Master (CC) & Expansion (EX) Cards

If more channels are required, up to 63 EX cards can be daisy-chained to the CC card front panel via RJ45 connector, or by rewiring the backplane. The Master and Expansion cards of the VDS240 Wireless Vehicle Detection System can be used in the following traffic controllers. With up to four optically isolated contact closure relays, channel status is configurable when using a TS2 controller.
