MTX-8685C STATUS INDICATORS

The MTX-8685C 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-8685C. An active DATA RX LED indicates data
is present at the output terminals of the MTX-8685C. When configured for RS-485, an active Hi-
Z LED indicates the MTX-8685C 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.
