Communicationsetting
Baud rate select: 9600bps (fixed)/ Data bits: 8 bits (fixed)
Parity: None (fixed)/ Stop Bits: 1(fixed)
Command message reference
PC sends to Monitor command packet followed by "CR". Every time PC sends control command to the Monitor, the Monitor shall response as follows:
1.If the message is received correctly, it will send "+" (02Bh) followed by "CR" (00Dh).
2.If the message is received incorrectly, it will send "-" (02Dh) followed by "CR" (00Dh).
Connections and communication settings
Choose one of the connections and set up properly before RS232 control.
RS232 serial port connection
The image below is just for illustration purpose, PL4901/PL5501/PL5502 use RJ45 connector in display side for RS232
connection.
