<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.

If monitors are connected as shown above, you can execute commands like “Set the volume of the
monitor with ID 4 to 20”.
