Hi, I have an advantech PCM-4153 board with 4 com ports. The user guide say port 2 can be configured as a RS485 port. I have a few doubts. I am using linux on this board. Will I need special drivers to use RS485 (the board uses sch3112 chip for IO) The user guide says to set a jumpe to switch from rs232 to rs485. Will I need to change the serial comm cod too? Is it OK if i do this:
1) COM 2 is configured as a serial port right now. 2) I dont change the code, just set the jumper to RS485. 3) I run the code, connect COM 2 to a RS485 to RS232 convertor, and rea in the output in using hyperterminal.Will the above work?
Thanks...
