(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 19), you can make
input mode selection/adjustment or can check the status of a specific
monitor.
You can also connect multiple monitors via a daisy chain by using a PC.
By assigning ID numbers to each monitor, you can make input mode
selection/adjustment or can check the status of a specific monitor.

232C connector) and the RS-232C input terminal on the monitor.
<DAISY 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 out-
put terminal and to the second monitor's RS-232C input terminal. Con-
nect 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.)
