Relocating the ribbon cable and setting the jumper
If the SVS 100 is currently configured for RS-232 communication, the ribbon cable
must be relocated and the jumper must be reset for RS-422 communication. See
figure A-3.
1. Disconnect the ribbon cable from the RS-232 receptacle, noting that the
red stripe of the cable is positioned relative to pin #1 of the receptacle.
Both RS-232 and RS-422 receptacles are mounted with pin #1 located on
the same side, relative to the circuit board.
2. Reconnect the ribbon cable to the RS-422 receptacle, as shown in
figure A-3. The red stripe of the ribbon cable must be positioned relative
to pin #1 of the RS-422 receptacle.
