ST-9284-N08 Vehicle Computer Unit

This Vehicle Computer Unit (VCU) is capable of tracking vehicles with precision even is adverse conditions.


Vehicles equipped with the EMTRAC system carry a compact, yet rugged, Vehicle Computer Unit (VCU), which is connected to an omni-directional antenna that receives location data and transmits priority requests to intersections through secure RF communication. The positioning capability is able to track vehicles with precision, and the radio range allows reliable intersection response— even in adverse conditions.


  • 900 MHz, frequency-hopping spread spectrum radio with secure, 256-bit AES encryption
  • Typical transmission range of 3,600 feet, enabling intersectionapproach zones of the same length
  • Integrated computer board contains ultra-fast processor and superior memory, while the MicroSD-card offers vast activity-log storage capability
  • Capable of communication through Ethernet, RS-232, or wireless connection
  • Supports up to 16 inputs and outputs in any combination
  • Capable of storing up to 5,000 intersection-approach zones
  • Ability to accept multiple inputs to prompt priority requests, including emergency light-bar, bus-door or pull-cord activity, schedule adherence, and passenger count
  • Time-out feature configurable to cease priority requests after designated amount of no-motion time
  • Programmable with Windows XP, Vista, 7, 8, 10 (or later) operating systems
