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.
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.
