Front Panel - Status LEDs
The two status LEDs are located on the front panel, directly beneath the AMX logo (FIG. 5):

Power Status
(
green
): Lights to indicate that the Transmitter is receiving power and is functional. If
the LED fails to light, check your 12VDC Power connection (see the Applying Power to the


Communication Status ( red ): Lights to indicate that the Transmitter is connected to the network.
Rear Panel - TUNER IN
The TUNER IN (RCA) connector accepts incoming QAM/ATSC TV signals via coax cable (FIG. 6).
In order to use the TUNER IN (RCA) connector with coax cable, you must first install the included
Coax-to-RCA adapter (see FIG. 25 on page 16).
Refer to the Connecting TV Sources to the Transmitter section on page 16 for details.
