MRX-8885 STATUS INDICATORS
The MRX-8885 receiver provides the following front panel LED status indicators to aid in
installation and troubleshooting:
DATA
These indicators turn green when any data activity is present. An active DATA TX LED
indicates data is present at the input terminals to the MRX-8885. An active DATA RX
LED indicates data is present at the output terminals of the MRX-8885. When configured
for RS-485, an active Hi-Z LED indicates the MRX-8885 has seized the data line to allow
data flow. The intensity of the indicators will vary with input data patterns, however, the
Hi-Z LED will typically appear dimmer than the Data Tx and Rx LEDs. The data channels
associated with these front panel DATA LEDs are listed below.

OLI 1
A bi-color LED indicator monitors the optical input signal that is being sent to the MRX-
8885 from video channels one through four of the MTX-8885. AC power and optical
input status associated with this LED are summarized below. Please note that data is
sent as a subcarrier on channel one’s video signal.
