Controlling the Monitor with a PC (RS-232C)

n

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.

[Example]

Set 1

Set 2

Set 3

Set 4

* If monitors are connected as shown above, you can

execute a command like “Set all monitors’ input settings to

PC1 DVI-D”.

n

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

specific 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.

Example: (When 4 monitors are connected, and

assigned ID numbers: 1 through 4)

VOLM030 +
WAIT
OK 001
OK 002
OK 003
OK 004

← 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:

VOLM ? ? ? +
WAIT
10 001

Volume settings for all

monitors are returned.

20 002
30 003
30 004

TIPS

• If repeater control is used during ID designation (IDSL,

IDLK), the ID designation is canceled.
