PC and Compatible Connections: If you are only talking to a
single SER-DMX and your wire length is short, you may be able to
cross wire the RS-232 serial port on your PC to talk to the SER-DMX.
This does not work on all PCs, as some don’t swing their RS-232 out-
puts as far as they should. If it does not work with your PC, you may
need to get a RS-232 to RS-422 converter to talk to the SER-DMX. To
cross wire the RS-422 / RS-485 signals from the SER-DMX to the RS-
232 serial port of an IBM compatible, cross connect the signals as fol-
lows:

The SER-DMX responds only to the command to enter the config-
uration mode, display status or upload/download its configuration. It
will ignore all other commands. It can share the same RS-422 serial
