The magnetometer and MicroRadar® sensors are wireless, transmitting their detection data in real-time via low-power radio technology to a nearby Sensys Networks access point that then relays the data to one or more local or remote trac management controllers and systems.The Sensys Networks FlexAP is an intelligent device operating under the Linux operating system that maintains two-way wireless links to a vehicle detection system’s sensors and repeaters, establishes overall time synchronization, transmits conguration commands and message acknowledgements, and receives and processes data from the sensors. The FlexAP then relays the sensor detection data to a roadside trac controller or remote server, trac management system, or other vehicle detection application.The FlexAP is the second generation of Sensys Networks access points and replaces the AP240. The FlexAP includes a higher sensitivity radio for more robust wireless links and more processing and memory capacity for additional applications. The FlexAP is housed in a robust enclosure that provides excellent protection against the environment.Types of FlexAPs. A FlexAP uses a single cable to support 10/100Base-T Ethernet communications and, in some versions, serial communications to the contact closure card that furnishes the interface to standard trac controllers.FLEX-AP-S, FLEX-AP-ES • RJ45 port supports serial interface to Contact Closure card (CC card) for relay of vehicle detection output via the EX cards or FlexConnect SDLC link• Supports Ethernet interface for eld conguration (via Sensys Networks AccessBox)• Statistics processing of sensor detection data only in FLEX-AP-ES• 48VDC power input from CC card via RJ45 port FLEX-AP-D, FLEX-AP-ED • RJ45 port supports Power-over-Ethernet (PoE) interface for relay of detection data directly to controller• Supports eld conguration over the Ethernet interface• Statistics processing of sensor detection data only in FLEX-AP-ED• 48VDC power input from PoE interface (adapter required)Functions / FeaturesSensys Networks radio communications• To/from wireless sensors• To/from repeatersRelay of sensor data• Via contact closure signals, FlexConnect SDLC link, or Ethernet interface to trac controller
