4.4 Controlling Margay with RS232/RS485
Connect the RS232 In to the computer. Loop thru with RS485.
Remote control with serial commands is a good way
to control a wall while it is operating. It’s also an easy
way to control Margays in a wall during initial setup
using one of the Clarity utility programs.

Cube IDs
When the cubes are connected in a series loop
(2.5.4 “Connections, Control: RS232 & RS485” on
page 28), each cube should have a unique ID. The ID
is set in the Serial Settings menu.
The Group ID and the Unit ID go together to
make the cube’s ID. Each of the two parts has a range
for characters from 0 to 9 and from A to Z (not case
sensitive).
Addressing the cubes
When you send a command, it will have an
address. There are five forms of the address.
• To address all the cubes in this serial loop, use **
for the address.
• To address a single cube, use the specific ID of
that cube, such as A6 or 00 or 1B.
• To address all the cubes with a certain Group ID,
use an address like 3* with will address all the
cubes with the Group ID of 3, but with any Unit
ID. If you have three walls, and all the cubes in
one of the walls have Group ID 3, this type of
command would address only this wall.
• To address all the cubes with a certain Unit ID,
use an address like *0 or *3.
Baud rate
Each cube’s baud rate must be set to the computer
or controller’s baud rate. The baud rate is not auto-
matically established, as it is in modems.
Terminating the series
If the serial string is very long, you may have to
terminate the last cube in the string for good commu-
nication. Check the Terminate RS485 box.
In most instances, this is not necessary. Terminat-
ing the string unnecessarily can cause its own com-
munication problems. The guide line is: If it works
without terminating, leave it alone.
