ENGLISH
Example: VOLM0030
VOLM 
 
 30 (“ 
 ” indicates a space.)
* Be sure to input 4 characters for the parameter. Pad with spaces if necessary.
Wrong: VOLM30 
Right: VOLM 
 
 30 
 (“ 
 ” indicates a space. “ 
 ” is the return code (0D
H
, 0A
H
 or 0D
H
).)
When inputting a negative value, specify a numerical value in three digits.
Example: AUTR-009
To use the six-digit command (MPOS), use a six-digit numerical value without spaces in between.
Example: MPOS010097
If a command has “R” listed for “DIRECTION” in the “RS-232C command table” on page 42, the current 
value can be returned by using “?” as the parameter.
Example: 1. If an ID number has not been set:
VOLM????   ← From PC to monitor (How much is current volume setting?)
30  
← From monitor to PC (Current volume setting: 30)
2. If an ID number has been assigned (For example, ID number = 1)
VOLM 
 
 
 ?  ← From PC to monitor (“ 
 ” indicates a space.)
30 
 001  
 
← From monitor to PC (“ 
 ”  indicates a space.)
<Response code format>
 When a command has been executed correctly
This is returned when execution of the command is 
fi nished.
 When a command has not been executed correctly*
*  This is returned when there is no such 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 execution of the command is taking some time
With some commands, “WAIT” is returned as a return 
value. Wait for a moment, and OK or ERR will be 
returned. New commands cannot be received during 
this time, even if they are sent.
 If RS-232C is locked
If RS-232C control has been locked with the 
operation lock (see page 32), LOCKED is returned 
as the returned value.
Communication procedure
Basic operation
<Command format>
When a command is sent from the PC to the monitor, the monitor operates according to the received 
command and sends a response message to the PC.

Advanced operation
This section explains commands for daisy chain connection. The basic communication procedure is the 
same as in the “Basic operation” section.
<ID numbers>
You can assign a unique ID number to each monitor (see page 27). This allows you to 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]
ID number: 1
ID number: 2
ID number: 3
ID number: 4
PC
  If monitors are connected as shown above, you can execute commands 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.
ID numbers do not have to be assigned in ascending order starting from the PC. They can also be 
connected as shown below.
 [Example]
ID number: 3
ID number: 2
ID number: 4
ID number: 1
PC

ENGLISH
<Commands 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
PC
IDST......A monitor receiving this command sets its own ID number in the parameter fi eld.
Example:  IDST0001
OK 
 001 ←  The ID number of this monitor is set to 1.
TIPS
You can automatically assign ID numbers by using the IDST command with the Repeater control (see 
“Repeater control” on page 39).
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
PC
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 number=1
   
 
 (the one directly connected to the PC) is set to 20.
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
VOLM0020   ← Sets volume of monitor with ID number: 2 to 20.
WAIT
OK 
 002
IDLK0000  
← Canceling fi xed ID number setting
WAIT  
← Canceling IDLK
OK 
 002  
← Cancelation complete
VOLM0010
OK 
 001  
← The volume of the monitor with ID number=1 
   
 
(the one directly connected to the PC) is set to 10. (IDLK is canceled.)
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.)
ID:001  IDLK:002   ← Returned response. The ID number is also displayed on the monitor screen.
IDCK000+   
← Repeater control 
(If a command is used with repeater control, ID designation using IDSL or 
IDLK is canceled.)
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.
