In order to reconfigure the RS485/422 channel, the rack card cover needs to be removed. To open the RT-913D, remove the two screws at the left rear of unit near data and fiber connections. Also remove the two screws at the right front of unit (top of cover). The configuration switch banks are located at the lower right corner of PCB next to the data terminals (See drawing below). - Page 7 A green LED indicator is provided to monitor the data coming in from the electrical interface, through the RT-913D, 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.
