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:
DB-25 DE-9 Signal Signal from/to SER-DMX
2 3 DATA OUT - Serial data into card (#5 green)
3 2 DATA IN - Serial data out from card (#3 black)
7 5 GROUND Signal Ground (#2 white or #7 blue)
Apple Macintosh Connections: Apple Macintosh computers
have true RS-422 serial ports built in. To connect to the SER-DMX, the
pin out is as follows (view is of male connector facing the end of the
cable):
t
o + serial data in to card (#5 yellow)
to - serial data in to card (#4 green)
12
345
678
from - serial data out from card (#2 black)
from + serial data out from card (#3 red)
signal ground (#1 blue or #6 white)
The SER-DMX expects to see the serial data in the following for-
mat:
ONE START BIT
EIGHT DATA BITS
ONE STOP BIT
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
