Serial Port Settings and Diagnostics
If you want to control the displays remotely with RS232 commands from a computer,
read this section. Otherwise, skip it.
Multiple displays can be linked together for RS232 control using a straight-through
Ethernet cable. For more information, see "RS232 Communication"on page 15.
RS232 is also used to upgrade the firmware of the display.

four times on the remote.
Group ID and Unit ID
Each display in the loop must have a unique ID.
The RS232 ID has two parts, Group ID and Unit ID. Each part has a range of 0–9, A–Z.
This range results in 1300 possible addresses.
You can group the displays by using the same letter or number of the Group ID, such
as
A
. In this way you can address the group as
A*
, and all the displays in the string
that have Group ID
A
and any Unit ID will execute the command.
Note:
It does not matter what order you use to set IDs for the displays. It is common practice
to use Unit IDs that are in order, left to right and top to bottom, but this is not mandatory.
The only rule is: DO NOT USE THE SAME ID FOR DIFFERENT DISPLAYS.
