eter field.
Example: IDST0001
OK
001
1 The ID number of this monitor is set to 1.
Note: You can automatically assign ID numbers by using the IDST
command with the Repeater control.
For example, using the command “IDST001
+
” automatically sets
the ID numbers as shown below.

IDSL:
The parameter of this command sets the ID number of the monitor.
The monitor is subject to the next command.
The monitor is subject to the next command.
Example:
IDLK:
The parameter of this command sets the ID number of the monitor.
The monitor is subject to all subsequent commands.
Example:
IDCK:
Provides screen display of the ID number currently assigned to a moni-

Example:
(After executing IDLK0002)
<Repeater control>
This system has a function to allow setting of multiple monitors con-
nected in a daisy chain using a single command. This function is called
repeater control.
repeater control.
You can use Repeater control function without assigning ID numbers.
[Example]
If monitors are connected as shown above, you can execute a com-
mand like “Set all monitors input settings to DVI: DIGITAL.
<Repeater control command>
Repeater control is achieved by setting the FOURTH CHARACTER of
the parameter to “
+
”.
Example:
In repeater control, responses are returned by all the connected moni-
tors.
If you want to determine that a value has been returned by a specific
If you want to determine that a value has been returned by a specific
