I see that the Pi Bridge connector on the RevPi Core has two RS485 interfaces on pins A9+A10 and B9+B10. Can these be used as regular RS484 ports i.e can they be made to appear as /dev/ttySX etc. to the OS? If so, what are the voltage levels and what is the Pi Bridge connector type?
Thank you.
RS485 On Pi Bridge
if you are not using the PiBridge for any RevPi Modules you could stop the PiConnect driver. In such a case you could use the pins for RS485 (see norm documents for levels etc.) communication using tty of Linux. BUT: The PiBridge connector is customer specific and there is no counterpart available. Please make it easy for yourself and use a USb to RS485 or RS232 converter to get your serial signals as tty under Linux.
There will be a special "RevPi connect"variant of the RevPi Core in the near future which will have RS485 screw terminals and which is operated as tty device under Linux.
