Controlling the Monitor with a PC RS-232C, 33 E

Controlling the Monitor with a PC (RS-232C)

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 34), you can make input mode selection/adjustment or can check the status of a specific monitor.

TIPS

•To control the monitor via RS-232C, set RS-232C/LAN

SELECT to RS-232C.

•You cannot use RS-232C and LAN control simultaneously.

PC connection

nOne-to-one connection with a PC

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)

nDaisy chain connection… Advanced operation

Connect with RS-232 straight cable between the PC’s COM

port (RS-232C connector) and the RS-232C input terminal on the first monitor.

Next, connect RS-232 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 conditions

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

Baud rate	*	Stop bit	1 bit

Data length	8 bits	Flow control	None

Parity bit	None

*Set to the same baud rate as the BAUD RATE setting of

SETUP menu. (Initial setting: 38400 bps)

*When connecting multiple monitors in a daisy chain, set all monitors to the same BAUD RATE.

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

Parameter field

(4 prescribed

(4 character string comprised of:

alphanumerical characters)

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

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 37, 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 34) has been assigned

(For example, ID number = 1).

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