Controlling the Monitor with a PC

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 25), you can make input mode selection/adjustment or 
can check the status of a speci

fi

 c monitor.
