Using LEDs to Diagnose Connection Problems
The YDI radio modem has four LED indicators to display its status.
Power (Red)
Indicates that 12-Volt power is applied when lit.
Traffic (Green)
Flashes when the receiver detects a signal from another radio.
Connected (Green)
Indicates connection with another radio is established when lit. If the
base station's "Connected" LED is off and then lights, it indicates that
both receivers and transmitters have made contact. Once lighted, the
LED may remain on for a while, meaning that it does not necessarily
show the present status of the base station radio modem. If the base sta-
tion is not attempting to make contact its indicator will be off; this does
not mean that the field station is failing.
Transmit (Green)
Indicates the radio is transmitting when lit.
