VOLM0030, VOLM0020 ←, IDST001 +, 004

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

nCommands for ID control

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

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.

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

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

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 33).

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 ←

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

Canceling fixed ID number setting Canceling IDLK

Cancelation complete

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

IDST001 +		← ID setting command with repeater control
WAIT
OK	001	← “OK” response from ID number: 1
OK	002	← “OK” response from ID number: 2
OK	003	← “OK” response from ID number: 3
OK	004	← “OK” response from ID number: 4 (End)

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

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

Example:

IDSL0002		←	The next command is 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	←	OK response from monitor with ID
			number: 2
VOLM0020		← Sets volume to 20.
OK	001		The volume of the monitor with ID
OK	001	← number: 1 (the one directly connected

to the PC) is set to 20.*

*The IDSL command is effective only once, for the immediately succeeding command.

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

IDCK........Provides screen display of the ID number currently

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

Example:

(After executing IDLK0002)

IDCK0000		← (Parameter has no meaning.)
		Returned response. The ID
ID : 001	IDLK : 002	← number is also displayed on the
		monitor screen.
IDCK000 +		← Repeater control. (If a command
WAIT		is used with repeater control, ID
WAIT		designation using IDSL or IDLK
ID : 001 IDLK : 000		is canceled.)
ID : 001 IDLK : 000
ID : 002 IDLK : 000
ID : 003	IDLK : 000
ID : 004	IDLK : 000
