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

„Commands for ID control

The command examples shown on this page assume the following connection and ID number set up.

IDLK ........The parameter of this command sets the ID

number of the monitor. The monitor is subject to all subsequent commands.

ID number: 1 ID number: 2 ID number: 3 ID number: 4

IDST .........A monitor receiving this command sets its own ID

number in the parameter field.

Example:

IDST0001

OK 001 ← The ID number of this monitor is set to 1.

Example:

IDLK0002		←	Following commands are for the monitor
			with ID number: 2.
WAIT		←	Searching for monitor with ID number:
			2
OK	002	← Found monitor with ID number: 2
VOLM0030		←	Sets volume of monitor with ID
			number: 2 to 30.*
WAIT		← Processing
OK	002

TIPS

You can automatically assign ID numbers by using the IDST command with the Repeater control (see “Repeater control” on page 15).

For example, using the command “IDST001+” automatically sets the ID numbers, as shown below.

[Example]

ID number: 1 ID number: 2 ID number: 3 ID number: 4

VOLM0020 ←

WAIT

OK 002 IDLK0000 ←

WAIT ← OK 002 ← VOLM0010

OK 001 ←

Sets volume of monitor with ID number: 2 to 20.*

Canceling fixed ID number setting

Canceling IDLK

The volume of the monitor with ID number: 1 (the one directly connected to the PC) is set to 10. (IDLK is canceled.)

OK	002	← “OK” response from ID number: 2
OK	003	← “OK” response from ID number: 3

IDSL ........The parameter of this command sets the ID number

of the monitor. The monitor is subject to the next command.

*The IDLK command remains effective until it is canceled, or power is shut off.

assigned to a monitor, and the ID number currently set for IDLK (if any).
