RR-915C STATUS INDICATORS
The RR-915C 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, 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 1 TX LED Data Status
Green Data Flow Present
Off Data Flow Not Detected
DATA 1 RX
A green LED indicator is provided to monitor the data coming in from the fiber, through the RR-915C,
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.
DATA 1 RX LED Data Status
Green Data Flow Present
Off Data Flow Not Detected
DATA 2 TX
A green LED indicator is provided to monitor the contact input from the electrical interface, through the
RR-915C, and out onto the fiber. Contact status associated with this LED is summarized below.
Data 2 TX LED Contact Status
Green Contact Input Closed
Off Contact Input Open
DATA 2 RX
A green LED indicator is provided to monitor the contact output from the fiber, through the RR-915C,
and out onto the electrical interface. Contact status associated with this LED is summarized below.
Data 2 RX LED Contact Status
Green Contact Output Closed
Off Contact Output Open
