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

Precautions when the PN-ZB01 (optional) is attached

• 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.)

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
