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.

TIPS

To control the monitor via RS-232C, set STANDBY MODE to STANDARD.

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

nDaisy chain connection… Advanced operation

PN-Y325 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.)

Example:

VOLM ? ? ? ?

From PC to monitor (How much

 

 

is current volume setting?).
