FlexControl & APCC
So much functionality to see, it seems a shame to hide it in the cabinet

The “brains” of your traffic detection system, in two convenient form factors for maximum detection flexibility and minimal power usage. TECHNICAL DOCUMENTS

  • Advanced processing power
  • Integrates two radios for maximum coverage
  • Two convenient form factors
  • Manages communications and data processing


The Sensys Networks FlexControl™ & APCC are state-of-the-art hardened LINUX computers responsible for managing radio communications and data processing for wireless sensor networks optimized for traffic applications. They provide a common platform to support multiple applications including actuation for traffic signal control, data analytics for arterial or freeway performance measures, travel time, and other custom applications. The common platform eliminates the need for separate systems for each application.

FlexControl & APCC process sensor data in a time-synchronized fashion, manage firmware updates for wireless components, and manage communications backhaul to central servers, all while consuming less than 1 watt of power. Multiple sensor types are supported including FlexMag magnetometers, MicroRadar, and Wi-Fi or Bluetooth re-identification detectors. Similarly, multiple interfaces are provided to relay data to traffic signal controllers, custom application controllers, and central servers.

FlexControl & APCC both come with Ethernet and dual USB interfaces, and ports for 2 external radio connections. The DIN or bracket-mounted FlexControl module has a compact form factor and includes additional RAM, a USB type-B port, and terminal block or barrel power connector options. It is designed for applications where traffic cabinets are not available or have limited space. The rack-mounted APCC card comes standard with contact closure support and has an optional expandable SD memory card slot, dual serial (DB9) interfaces or a single serial port with a built in cellular modem. It is designed for applications where traffic cabinets are available with rack space.


  • Manages radio communications
  • Sensor data processing & storage
  • Multiple traffic detection & data signaling interfaces
  • Master timebase for all wireless sensors
  • Radio signal quality measurement
  • Multiple peripheral interfaces
  • Firmware upgrades
  • Easy installation
  • Low power
  • No calibration or adjustments needed


A serial port protocol (SPP) digital radio that transmits data between Sensys Networks sensors or repeaters and the FlexControl or APCC gateway housed in the controller cabinet. Up to two Radios can connect to each gateway for maximum detection coverage.


The FlexIsolator™ provides two independent isolator ports for electrical isolation and surge protection for up to two digital radios, and AC power cross protection for APCC, FlexControl or FlexConnect. The standard single-port Isolator provides the same protection but for one radio at a time.


The FlexConnect™ provides an SDLC interface for FlexControl or APCC, replacing the functionality of one or more EX cards with up to 64 channels. This reduces system costs and frees up card slots in controller cabinets.
