Controlling the Monitor with a PC RS-232C

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 31), 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, and STANDBY MODE to

STANDARD.

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

Communication conditions

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

Baud rate	9600bps	Stop bit	1 bit

Data length	8 bits	Flow control	None

Parity bit	None

Communication procedure

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.

To COM port

RS-232 straight cable

RS-232C (commercially available) input terminal

nDaisy chain connection… Advanced operation

PN-U553/PN-U473/PN-U423 monitors can be connected together in a daisy chain connection.

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.)

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

Do not use spaces for MPOS, DATE, and SH01 through SH07. 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 34, 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 31) has been assigned (For example, ID number = 1).

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