Truck Interface Module (TIM)
Components
The 2-part Enclosure houses the circuit
boards and a Baffle to hold the circuit
boards in place.
The Backplane circuit board provides
connectors for the Processor board, RF
board, Barrier cable and the TIM Console
connector.
The Processor Board contains the TIM
software and firmware. The processor
controls all transactions, monitors
dispensed fuel, and calculates temperature
compensation. It also stores transaction
and authorization data and controls
sending transaction data to the ADC
Central Controller via the RF transceiver
board. It also has a reset button and hosts
a 64mb or greater capacity compact flash
card.
The RF Transceiver board uses spread
spectrum frequency hopping technology
in the 2.401-2.495 Gigahertz range. The
board’s function is to establish wireless
communications with the ADC Central
Controller.
A
n optional Manual Air or Hydraulic
V
alve is also available for non-electric
controlled applications.
