This section explains commands for daisy chain connection. The basic communication procedure is the
same as in the “Basic operation” section.
<ID numbers>
You can assign a unique ID number to each monitor (see page 31). This allows you to control a particular
monitor in a daisy chain of monitors.
Up to about 20 monitors can be connected, depending on the length of RS-232C cables and installation
environment.
You can assign ID numbers either from the menu screen (using the remote control) or from the PC using
RS-232C cable.
[Example]
If monitors are connected as shown above, you can execute commands like “Set the volume of the
monitor with ID 4 to 20”.
When controlling monitors linked in a daisy chain by designating ID numbers, you should basically avoid
any duplication of ID numbers.
ID numbers do not have to be assigned in ascending order starting from the PC. They can also be
connected as shown below.
[Example]
PC ID number: 1 ID number: 2 ID number: 3 ID number: 4
PC ID number: 3 ID number: 2 ID number: 4 ID number: 1
