Controlling the Monitor with a PC

You can control this monitor from a PC via RS-232C (COM 
port) on the PC.
PC connection
Connect with RS-232 straight cable between the PC’s COM 
port (RS-232C connector) and the RS-232C input terminal on 
the monitor.

RS-232 straight cable 
(commercially available)To

RS-232C input termina
l

Communication conditions
Set the RS-232C communication settings on the PC to match 
the monitor’s communication settings as follows:

Baud rate9600 bpsStop bit1 bit
Data length 8 bits Flow controlNone
Parity bit None

Communication procedure
nCommand 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.

Return code 
Command field   
(4 prescribed   
alphanumerical characters

)
  Parameter fiel

(4 character string comprised of:  0-9, +, -, space, ?)

 Example:    VOLM0030
 
VOLM 

 
  30

*  Be sure to input 4 characters for the parameter. Pad with 
spaces (“

”) if necessary.  
(“ 

 ” is a return code (0DH, 0AH or 0DH))
Wrong
 
: VOLM30

Right   : VOLM 
 
  30

When inputting a negative value, specify a numerical value in 
3 digits.
 Example: AUTR-009

Do not use spaces for MPOS. Specify parameters using 6 
numerical characters. Example: MPOS010097

If a command has “R” listed for “Direction” in the  
“RS-232C command table” on page 14, the current value can 
be returned by using “?” as the parameter.
 Example:
VOLM ? ? ? ? ←
From PC to monitor (How much 
is current volume setting?).
30←From monitor to PC (Current 
volume setting: 30).
*  If an ID number (see page 7) has been assigned  
(For example, ID number = 1).
VOLM 

? ←From PC to monitor.
30 
  001 ←From monitor to PC.
