Controlling the Monitor with a PC (RS-232C) You can control this monitor from a PC via RS-232C (COM port) on the PC. TIPS • To control the monitor via RS-232C, set RS-232C/LAN SELECT to RS-232C. • When STANDBY MODE is set to LOW POWER, control is not possible in standby mode. • You cannot use RS-232C and LAN control simultaneously. PC connection Connect the RS-232C conversion cable (supplied) to the RS232C input terminal on the monitor. Connect the RS-232C conversion cable (supplied) to the COM port (RS-232C port) on your computer with an RS-232 cable (straight). Communication conditions Set the RS-232C communication settings on the PC to match the monitor's communication settings as follows: Baud rate Data length Parity bit * 8 bits None Stop bit 1 bit Flow control None * Set to the same baud rate as the BAUD RATE setting of SETUP menu.

You can control this monitor from a PC via RS-232C (COM
port) on the PC.
TIPS
•
To control the monitor via RS-232C, set RS-232C/LAN
SELECT to RS-232C.
•
When STANDBY MODE is set to LOW POWER, control is
not possible in standby mode.
•
You cannot use RS-232C and LAN control simultaneously.
PC connection
Connect the RS-232C conversion cable (supplied) to the RS-
232C input terminal on the monitor. Connect the RS-232C
conversion cable (supplied) to the COM port (RS-232C port)
on your computer with an RS-232 cable (straight).

When inputting a negative value, specify a numerical value in
three digits.
Example: AUTR-005
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 43, 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).
