Using the LCD with RS-232C
Functions that can be controlled
via RS-232C are:
• Powering ON or OFF
• Switching input signals
NOTE:
If your PC (IBM or IBM compatible) is equipped
only with a 25-pin serial port connector, a 25-pin serial port
adapter is required. Contact your dealer for details.
NOTE:
In order to function, the RS-232C OUT terminal
can only be connected to another monitor of the same
model. Do not connect to other types of equipment.
This LCD monitor uses RXD, TXD and
GND lines for RS-232C control.
The reverse type cable (null modem cable)
should be used for RS-232C control.
