MTX-8485C STATUS INDICATORS

The MTX-8485C transmitter 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 MTX-8485C. An active DATA RX LED indicates data

is present at the output terminals of the MTX-8485C. When configured for RS-485, an active Hi-

Z LED indicates the MTX-8485C 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

A bi-color LED indicator monitors the optical input power of the data signal that is being

received at the MTX-8485C from the MRX-8485C. AC power and optical input status associated

with this LED are summarized below.
