MTX-8885C STATUS INDICATORS
The MTX-8885C 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-8885C. An active DATA RX LED indicates data
is present at the output terminals of the MTX-8885C. When configured for RS-485, an active Hi-
Z LED indicates the MTX-8885C 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.
