3. TX320 Functions
3.1 LED Function
The TX320 has four LEDs used to indicate the state of the TX320 transmitter.
When power is first applied to the TX320, the four LEDs will cycle through
quickly, then the Synchronizing Clock to GPS LED will light for 15 minutes.
If there are data in a buffer waiting for transmission time, the Data In Buffer
LED will light.
During transmission, the Transmitting LED will light.
The Status LED will only light after the Diagnostics button has been
depressed. Press and hold the Diagnostics button for about 2 seconds. The
Status LED will flash once to indicate the Failsafe has not been tripped. If the
LED flashes twice, the Failsafe has tripped. To clear the Failsafe, press and
hold the diagnostic button for about 10 seconds.
