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. For more infor-
mation, see "Connecting RS232 Communication" on
page 19.
RS232 is also used to upgrade the firmware of the unit.
RS232 IDs
Each unit in the loop must have a unique RS232 ID. Open

In the Serial Port Settings menu, you specify an ID that
is unique for each Bay Cat X in this RS232 loop.
The ID is in two parts, Group ID and Unit ID. Each of
these has a range of 0–9, A–Z. This range results in 1296
possible addresses.
You can group the Bay Cat Xs by using the same letter
or number of the Group ID, such as 8. In this way you can
address the group as 8*, and all the Bay Cat Xs in the string

Addressing Bay Cat X
Part of the RS232 command will be an address. This
address may take several forms. For example, suppose we
have 8 units in one area divided into two groups. We might
set the ID s of the units like this:
Group ID
A

With this scheme, we have four ways to address these
Bay Cat Xs:
Type of
Addresses
A3 Only the specific Bay Cat X addressed will
B4 obey the command. Also, the Bay Cat X
etc. will respond to the host computer.
** All Bay Cat Xs in this RS232 loop will obey
the command
*4 Both the Bay Cat Xs whose IDs end in "4"
will obey this command
B* All four Bay Cat Xs in Group B will obey
the command
Response type and terminator
The ASCII Response Type determines what type of
data will be returned to the computer. For human readable
text in a serial program choose Symbolic. For computer-
read data you can use Numeric or Data Only.
