RT-915C STATUS INDICATORS
The RT-915C 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.
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 RT-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 RT-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
RT-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 RT-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
