Mrx-8485 Status Led Indicators - American Fibertek MTX-8485 Instruction Manual

MRX-8485 STATUS INDICATORS
The MRX-8485 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-8485. An active DATA RX
LED indicates data is present at the output terminals of the MRX-8485. When configured
for RS-485, an active Hi-Z LED indicates the MRX-8485 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-
8485 from the four video channels of the MTX-8485. 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.
