Overview


The Diablo Controls Hands-Free Automatic Vehicle Identifier System

Consists of an AVI Transmitter and an AVI Receiver. The AVI System has many different uses and applications including:

  • Emergency vehicle Access
  • Mass transit
  • Shuttle Buses
  • Private Homeowner Access
  • Trucking Companies
  • Manufacturing Facilities
  • Fork Lifts
  • Airport Access
  • RailL Cars
  • And many other applications

Depending on the type of application, the user can choose to have the AVI System hands-free or manual. The AVI system is configured and tested at the factory, providing a true plug and play environment.  All codes are documented and saved at the factory to eliminate duplicate codes being used by existing customers.

The AVI system has multiple code capability allowing for greater versatility and security.

The AVI Transmitter is potted in a thermal epoxy compound and is mounted to the underside of a fire apparatus, police car, bus, light-rail train, and many other vehicles.  When the vehicle approaches a gated area, the code is received by a loop buried in the ground ahead of the gate or barrier. The receiver is the “smarts” of the system.  It receives the coded message coming from the transmitter.  If the transmitted code matches the pre-programmed code stored in the receiver, a relay contact is closed and a red LED is illuminated indicating a valid code is being received. This signal is then passed on to a gate controller, which automatically opens the gate or performs some other security function.

The AVI-X is a dual code transmitter encased in a rugged housing.  It can transmit up to 19,683 different codes using the standard Motorola code format. Furthermore, it is compatible with existing systems.

There are two models available:

  • AVI-X-1 – constantly transmits its single code as long as power is applied to the unit.
  • AVI-X-2 – transmit its primary code continuously unless the switch is pressed.

The transmitter is typically attached to the undercarriage of the desired vehicle and the two wires are hooked into the switched DC power source usually located someplace on the dashboard.

The transmitter comes factory preset with the programmed code(s) installed. The code(s) are easily changed if necessary. However, for security reasons, this must be done by the factory. Please contact the factory for any programmed code changes.

  • Voltage:  12 VDC (10 to 15 volts DC) protected from momentary overvoltage and/or voltage reversal.

  • Frequency:  375 kHz and complies with FCC part 15 for unlicensed operation.
  • Codes:  Any two codes between 1 and 19,683 using the standard Motorola trinary format.
