MT-945SL STATUS INDICATORS
The MT-945SL transmitter provides the following LED status indicators to aid in installation and
troubleshooting:
DATA TX / RX INDICATORS
DATA TX and DATA RX indicators are provided to monitor each of the two available data channels.
TX1 and RX1 correspond with the multi-protocol input/output of data channel 1. TX2 and RX2
correspond with the multi-protocol input/output of data channel 2.
DATA TX
A green LED indicator is provided to monitor the data coming in from the electrical interface, through
the MT-945SL, and out onto the fiber. The intensity of this indicator will vary with input data patterns,
however in typical applications it will cycle on and off as data is transmitted. Data transmitted status
associated with this LED is summarized below.

DATA RX
A green LED indicator is provided to monitor the data coming in from the fiber, through the MT-945SL,
and out onto the electrical interface. The intensity of this indicator will vary with input data patterns,
however in typical applications it will cycle on and off as data is received. Data received status
associated with this LED is summarized below.
