MT-944C-SL STATUS INDICATORS
The MT-944C-SL 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 the data and contact closure channels. TX1
and RX1 correspond with the multi-protocol input/output of data channel.
DATA TX
A green LED indicator is provided to monitor the data coming in from the electrical interface, through
the MT-944C-SL, and out onto the fiber. The intensity of this indicator will vary with input data patterns,
however in typical data applications it will cycle on and off as data is transmitted. Data transmit status
associated with this LED is summarized below.
DATA TX LED
Green

DATA RX
A green LED indicator is provided to monitor the data/contact closure coming in from the fiber, through
the MT-944C-SL, and out onto the electrical interface. The intensity of this indicator will vary with input
data patterns, however in typical data applications it will cycle on and off as data is received. Data
receive status associated with this LED is summarized below.
