I know this thread is 7 years old, but information is never old.
Is there anywhere I can learn in small details how to use hyperterminal or other serial PC software to communicate with 6300PX* boards via CON4/5, oops, now I realize is CON6 (white 4 pins) since there is a RS232 chip to it.
Is there any specific protocol to talk with the board?
I will really appreciate any help.
Thanks
