Controlling the Monitor with a PC
You can control this monitor from a PC via RS-232C (COM
port) on the PC.
You can also connect multiple monitors via a daisy chain by
using a PC. By assigning ID numbers to each monitor (see
page 26), you can make input mode selection/adjustment or
can check the status of a specific monitor.
PC connection
One-to-one connection with a PC
Connect with RS-232C straight cable between the PC’s COM
port (RS-232C connector) and the RS-232C input terminal on
the monitor.

Advanced operation
Connect with RS-232C straight cable between the PC’s COM
port (RS-232C connector) and the RS-232C input terminal on
the first monitor.
Next, connect RS-232C straight cable to the first monitor’s
RS-232C output terminal and to the second monitor’s
RS-232C input terminal. Connect in the same way to the third
and subsequent monitors.
Up to 25 monitors can be connected. (Depending on the
length of the cable used and the surrounding environment.)

Communication procedure
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.

* Be sure to input 4 characters for the parameter. Pad with
spaces (“ ”) if necessary.
(“ ” is a return code (0D

Wrong : VOLM30
Right : VOLM 30
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. Specify parameters using a specified number of
characters.
Example: MPOS010097
If a command has “R” listed for “DIRECTION” in the
“RS-232C command table” on page 29, 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)

(For example, ID number = 1)

TIPS
• “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 is used, but no monitor
with ID number: 2 is found), no response is returned.

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 (see page 24)

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.
VOLM0020

INPS0001
WAIT

Interval of 100 ms or more
Advanced operation
This section explains commands for daisy chain connection.
The basic communication procedure is the same as in the
“One-to-one connection with a PC” section.
ID numbers
You can assign a unique ID number to each monitor (see
page 19). 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
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
