3 Operation
When Power is first applied to the transmitter the time is set to 00:00:00. Then the
transmitter reads configuration parameters, user adjustable via key pad, from the
internal flash memory. The transmitter then sends information to the GPS unit and
waits for time information from the GPS unit. Depending on the location, weather
conditions, time of day, etc. this can require up to several minutes for the initial
time verification. Once the transmitter has received the GPS unit signal for time,
the transmitter sets its internal clock to that time. The transmitter then starts to
transmit its internal time once every second. The transmission signal are depends
on one-watt FM signal at approximately 72.2 MHz. The transmitter continually
monitors the GPS unit and the transmitter’s internal clock is updated every time the
transmitter received data from the GPS unit.
