<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.
The number of connectable monitors varies depending on the length of the cable used and the
surrounding environment.
You can use Repeater control function without assigning ID numbers.
[Example]
PC
If monitors are connected as shown above, you can execute a command like "Set all monitors' input
settings to INPUT1 (DVI: DIGITAL)".
<Repeater control command>
Repeater control is achieved by setting the FOURTH CHARACTER of the parameter to "+".
Example:
← Sets volume of all monitors to 30.
VOLM030+
In repeater control, responses are returned by all the connected monitors.*
If you want to determine that a value has been returned by a specific set, assign ID numbers to
each monitor in advance.
If no response is returned, this may be because the monitor has not received (or is still processing)
the command, so it is possible that new commands may not be executed even if they
are sent.
* If power is turned "OFF" by Repeater control, only the monitor closest to the PC may return a
response.
Example:
(When 4 monitors are connected, and assigned ID numbers: 1 through 4)
VOLM030+
WAIT
OK 001
OK 002
OK 003
← If 4 monitors are connected in a chain, reliable operation can be ensured by sending
OK 004
a new command only after a reply has been returned by 4th (last) monitor.
Repeater control can also be used for reading settings.
Example:
VOLM???+
WAIT
10 001
20 002
Volume settings for all monitors are returned.
30 003
30 004
• If repeater control is used during ID designation (IDSL, IDLK), the ID designation is canceled.
