NOTE: If your PC (IBM or IBM compatible) is equipped only with a 25-pin serial port connector, a 25-pin serial port adapter
* RS-232C OUT terminal can connect MDT402S / MDT461S only. Do not connect other equipment.
The following control sequence is used for a single MDT402S / MDT461S. To control multiple MDT402S / MDT461S monitors that
are daisy-chained together please use the extended control command. Instructions for the extended control command can be found
on the CD included with the display. The file is called "External_control_MDT4XXS.pdf". When using the following control
commands, all of the daisy-chained monitors can be controlled at the same time from one monitor. Reply and status commands,
