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