Hi,
My device is RS485 output.My embedded board contains one RS 485 port.
when i am interfacing my device output(RS485) to embedded pc.Its not working.Its working the on the RS 232 port when I am using RS485 to RS232.
So how test in embedded pc RS485 is working or not.In 232 we can do the loop back test.
whatever the possibilities available please inform to me .
