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.
