External Control
RS232 control is not necessary for operation but is a convenient way to control displays from a computer at
a distance. Most functions that can be done with the remote, can also be done with RS232 commands.
RS232 Command Format
Commands sent from an automation/control system or PC to the display must have the following format:
STX (1byte) + IDT (1byte) + Type (1byte) + CMD (3bytes) + [Value/ Reply (1byte)] + ETX (1byte)
STX：Start byte = 07
IDT：Don’t care
Type：Read or Write command, 01: read, 02: write; 00: return to host (from monitor)
CMD：as following tables
Value：Setting Value of “Write Command”
Reply：Return Value of monitor
ETX：End byte = 08
Transmit from PC (Host)
