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

„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”.

„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

10001

20002

30003

30004

Volume settings for all monitors are returned.

TIPS

•If repeater control is used during ID designation (IDSL, IDLK), the ID designation is canceled.
