(1) Communication procedure
<Command format>
When a command is sent from the PC to the monitor, the monitor oper-
ates according to the received command, and sends a response mes-
sage to the PC.
Example: VOLM0030
VOLM
30
*Be sure to input 4 characters for the parameter. Pad with spaces
(“
”) if necessary.
(“[Enter]” is a return code (0DH, 0AH or 0DH))
Wrong : VOLM30 [Enter]
Right : VOLM
Right : VOLM
30 [Enter]
When inputting a negative value, specify a numerical value in three digits.
Example: AUTR-009
Do not use spaces for MPOS, DATE, and SC01 through SC08. Spec-
ify parameters using a specified number of characters.
Example: MPOS010097
If a command has “R” listed for “DIRECTION” in the “RS- 232C com-
mand table”, the current value can be returned by using “?” as the
parameter.
parameter.
Example :
VOLM????
1 From PC to monitor

30
1 From monitor to PC (Current volume setting: 30)
If an ID number has been assigned (For example, ID number

<Response code format>
• “ERR” is returned when there is no relevant command or when the
command cannot be used in the current state of the monitor.
• If communication has not been established for reasons such as a bad
connection between the PC and monitor, nothing is returned (not
even ERR).
• If no monitor has been assigned the designated ID number (e.g. if the
command IDSL0002 [Enter] is used, but no monitor with ID number: 2
is found), no response is returned.
■ If execution of the command is taking some time
When the following commands are used, “WAIT” is returned.
In this case, a value will be returned if you wait a while. Do not send any
command during this period.
No ID number is attached to WAIT response.
• Commands which return WAIT:
1 When repeater control is used
2 When an IDSL or IDLK command is used
3 When one of the following commands is used:
RSET, INPS, ASNC, WIDE, EMAG, EPOS, PXSL, POWR,
AGIN, MWIN, MWIP, MWPP, ESTG
■ When control via RS-232C is locked (to prevent use) using the
operation lock function

<ID numbers>
You can assign a unique ID number to each monitor. This allows you to
control a particular monitor in a daisy chain of monitors.
control a particular monitor in a daisy chain of monitors.
You can assign ID numbers either from the menu screen (using the
remote control) or from the PC using RS-232C cable.
[Example]
If monitors are connected as shown above, you can execute commands
like “Set the volume of the monitor with ID 4 to 20”.
like “Set the volume of the monitor with ID 4 to 20”.
When controlling monitors linked in a daisy chain by designating ID
numbers, you should basically avoid any duplication of ID numbers.
■ When a command has been executed correctly
A response is returned after a command is executed.

<Commands for ID control>
The command examples shown on this page assume the following con-
nection and ID number set up.
IDST: A monitor receiving this command sets its own ID number in the
parameter field.
Example: IDST0001
OK
001
1 The ID number of this monitor is set to 1.
Note: You can automatically assign ID numbers by using the IDST
command with the Repeater control.
For example, using the command “IDST001
+
” automatically sets
the ID numbers, as shown below.

IDSL: The parameter of this command sets the ID number of the monitor.
The monitor is subject to the next command.
Example:
IDSL: The parameter of this command sets the ID number of the monitor.
The monitor is subject to all subsequent commands.
Example:
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)
<Repeater control>
This system has a function to allow setting of multiple monitors con-
nected in a daisy chain using a single command. This function is called
repeater control. You can use Repeater control function without assign-
repeater control. You can use Repeater control function without assign-
ing ID numbers.
[Example]
*If monitors are connected as shown above, you can execute a com-
mand like “Set all monitors’ input settings to PC1 DIGITAL”.
<Repeater control command>
Repeater control is achieved by setting the FOURTH CHARACTER of
the parameter to “
+

Example:
IDSL0002

WAIT
1 Searching for monitor with ID number : 2

Repeater control is achieved by setting the FOURTH CHARACTER of
the parameter to “

Example:
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
If you want to determine that a value has been returned by a specific

When some monitors do not return their responses, the probable cause
is that the monitors could not receive the command or command pro-

cessing is not complete. Do not send a new command.
Example:
(When 4 monitors are connected, and assigned ID numbers: 1 through 4)
Repeater control can also be used for reading settings.
Example:
Note:
• If repeater control is used during ID designation (IDSL, IDLK),
the ID designation is canceled.
• Commands that use parameters consisting of more than four char-
acters can not be controlled by repeater control.
<Communication interval>
• After OK or ERR is returned, you must send the following commands.
To set a timeout for the command response, specify 10 seconds or
longer.
• Provide an interval of 100 ms or more between the command
response and the transmission of the next command.
