RR-915C-SL STATUS INDICATORS
The RR-915C-SL receiver 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.
DATA 1 TX and RX correspond with the multi-protocol input/output of DATA CH 1. DATA 2 TX and RX
correspond with the contact closure input/output of DATA CH 2.
DATA 1 TX
A green LED indicator is provided to monitor the data coming in from the electrical interface, through
the RR-915C-SL, 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.
