Power Supply Fault Detection
Each voltage supply has fault detection to determine if the voltage supply is function-
ing correctly. Output tolerance is tested to ±5 percent. If any of the voltage supplies
fail, the fault signal from the power supply to the digital board defaults to low.
AA3152 Universal Toll Antenna
The AA3152 antenna specifications are as follows:
Operates in the location and monitoring service band (902 to 928 MHz).
Optimum radiation pattern — Virtually no side or back lobes help to confine
antenna coverage to a single lane.
Weatherproof — Each antenna is housed in a radome made of materials with
favorable electrical characteristics and resistance to ultraviolet radiation.
Bandpass filtering helps to attenuate interference from other RF sources.
Environmental Specifications
The AA3152 UTAs can withstand the environmental tolerances shown in
Table C-1.
