3.5.3 Serial Port Settings
This applies only if you use RS232 commands to control the Bay Cat X.
If you wish to control Bay Cat Xs remotely with RS232
commands from a computer, read this section. Otherwise,
skip it.
Bay Cat Xs can be linked together for RS232 using
straight-through 8-conductor cable with RJ-45 connectors.
This is the common type of LAN connection cable, not
null-modem, sometimes call Cat-5 cable.
RS232 is also used to upgrade the firmware of the unit.
Adapter from computer to RJ45
At the computer end, you will need an adapter to go
from the computer’s 9-pin serial output connector to a
female RJ45 connector. Electronics stores have these
ready-to-wire types. Buy one with a female 9-pin sub and
connect the wires as shown.
Connect all the Bay Cat Xs together through their
RS232 ports: from the computer to the first Bay Cat X
RS232 IN; from the first Bay Cat X RS232 OUT to the next
Bay Cat X RS232 IN, etc. It doesn’t matter what order you
string them together. Most RS232 signals easily travel up to
150 ft. (50 m) between Bay Cat Xs.
Setting Unit IDs
Each Bay Cat X in the RS232 series needs a unique ID
so it can be individually addressed. To set unit IDs, go to
Main Menu > Advanced Options > Serial Port Set-
tings.

To go from 9-pin D-sub serial connector on the back of
the ccomputer to an RJ45 connector, use a standard
RJ45-to-9-pin adapter. Wire it internally as shown. The
wiring shown for this adapter is correct for straight-thru
cables. Straight-thru cables are wired 1-to-1, 2-to-2, etc.
