I'm trying to program the TWR-SERs UART to become an RS485 interface.
1/ Does anyone know what the correct jumper settings are for J13? I propose to jumper...
2/ Which UART is TWR-SER connected to on the TWR-K60N512?
3/ Is pin 5 on the 9 way d-type RS232/485 connector the 0V (GND)?
It's hard work trying to figure some of this out!
