232C INPUT terminal on the back of monitor.

Connect with RS-232C cross cable between the PC COM port (RS-232C connector) and the RS-
232C INPUT terminal on the back of monitor.
Next, connect RS-232C cross cable to the first monitor’s RS-232C OUTPUT terminal and to second
monitor’s RS-232C INPUT terminal. Connect in the same way to the third and subsequent monitors.
Up to about 20 monitors can be connected, depending on the length of RS-232C cables and
installation environment.

■ Set the RS-232C communication settings on the PC to match the monitor’s communication settings.

■ 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 54). 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 (via remote control or the control buttons on
the monitor) or from the PC using RS-232C cable.

PC

ID number: 1

ID number: 2

ID number: 3

ID number: 4

[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.
If the same ID number is assigned to multiple monitors, only the monitor closest to the PC can be
controlled with that ID number.
If monitors are connected as shown below, only the monitor 1 can be accessed with ID number 2.
Monitor 2 cannot be controlled using that ID number.
