<Repeater control>
This system has a function to allow setting of multiple monitors connected in a daisy chain using a
single command. This function is called repeater control.
You can use Repeater control function without assigning ID numbers.

You can use Repeater control function without assigning ID numbers.

Set 2
Set 3

PC
If monitors are connected as shown above, you can execute a command 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:
VOLM030+
← Sets volume of all monitors to 30.
In repeater control, responses are returned by all the connected monitors.
If you want to determine that a value has been returned by a specifi c set, assign ID numbers to
each monitor in advance.
When some monitors do not return their responses, the probable cause is that the monitors could not
receive the command or command processing is not complete. Do not send a new command.
If you want to determine that a value has been returned by a specifi c set, assign ID numbers to

When some monitors do not return their responses, the probable cause is that the monitors could not
receive the command or command processing is not complete. Do not send a new command.
Example:
(When 4 monitors are connected, and assigned ID numbers: 1 through 4)

← If 4 monitors are connected in a chain, reliable operation can be ensured by sending
a new command only after a reply has been returned by 4th (last) monitor.
Repeater control can also be used for reading settings.
Example:

* This is returned when there is no such command, or when the command cannot be used in the current state of
the monitor.
* If communication has not been established for reasons such as a bad connection between the PC and monitor,
nothing is returned (not even ERR).
* If no monitor has been assigned the designated ID number (e.g. if the command IDSL0002
is used, but no
monitor with ID number: 2 is found), no response is returned.
