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

Caution

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.

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.)

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 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 16, 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 13) has been assigned

(For example, ID number = 1).
