CR-100: AVI Code Reader System


The Model CR-100 AVI Code Reader simplifies the process of validating and identifying the code programmed into Reno A&E Model AVI-X Automatic Vehicle Identification transmitters.

  • LED display provides indication of transmitter code being read
  • Confirms operation of AVI-X transmitter
  • Battery condition LEDS provide indication of:
    - Adequate battery power (green LED on)
    - Low battery power (red LED on)
  • Monentary contact power switch prolongs battery life

AVI System:
AVI-X-n* Transmitter
n* Designates Unique Transmitter Code		 AVI-A-n* Receiver
n* Designates Unique Receiver Code		 AVI-C Receiver

The Model AVI-X-n* transmitter is designed to work in conjunction with either the Model AVI-A-n* receiver or the Model AVI-C receiver.
The system provides Automatic Vehicle Identification (AVI) and/or priority access.
The Model AVI-X-n* transmitter communicates with either receiver through standard roadway loops. When power is applied the transmitter sends out a continuous low frequency coded signal. This coded signal is permanently programmed into the transmitter
at the time of manufacture. The transmitter is ruggedly built and is designed to be securely mounted to the underside of the vehicle and connected to the vehicle’s electrical system.		 The Model AVI-A-n* receiver is programmed to identify any one of 19,683 possible codes. When the transmitter code matches the
receiver code, the receiver provides a signal (relay contact closure) for external use. The receiver requires no adjustment or setup.		 The Model AVI-C receiver is a two channel, card-rack type receiver that identifies all codes. Each channel is capable of independently
identifying all 19,683 individual transmitter codes and can be programmed to accept or reject each code. The Model AVI-C provides an output signal (relay contact closure or solid state output) for any of the 19,683 possible codes that have been programmed as a valid code. The AVI-C uses two loops (one per channel) installed in the roadway surface to receive transmitter codes. The AVI-C continually monitors the integrity of the loop circuits. The AVI-C receiver includes a DB-9 RS-232 connector that facilitates communication with external equipment.

Common Applications of the AVI System:
  • Traffic Signal Preemption - Ambulances, fire trucks, and other emergency vehicles can be equipped with AVI technology to control traffic signals outside of their facilities so that they have immediate, safe access to roadways.
  • Gated Access - Some municipalities use the Reno A & E AVI system at gated communities, industrial complexes, and other restricted areas so that emergency vehicles are provided unrestricted access to those areas - saving time, property, and lives. The cities in the Las Vegas, Nevada metropolitan area use proprietary coded Reno A & E AVI system components.

  • Secure Parking - AVI technology is an inexpensive way to allow for hands-free access to parking lots at airports, hospitals, and industrial complexes. Businesses and communities can control access, maintain security, and administer parking automatically.

  • Fleet Vehicles - The AVI system provides a cost efficient way for companies with small fleets to control access to loading bays, secure parking areas, and passage through controlled areas.

  • Bus Priority - Many public transportation systems use AVI technology to allow traffic signal preemption in the event a bus is running behind schedule.

  • Light Rail - AVI systems on trains provide train presence information at busy signalized intersections. Some transit systems have transmitters on the front and the back of their trains to not only allow them immediate access, but to return the intersection to road traffic after the train has passed. A special version of the AVI-X transmitter was developed in response to a request from the Utah Transit Authority for use on light rail trains in the greater Salt Lake City region.

  • Airports - Many airports use AVI technology to monitor and/or control ground vehicle transportation inside the airport facility.
