RdvPi Connect+ : Device path for embedded RS485 port
Posted: 26 Aug 2019, 16:48
Hello!
I wat to connect slave modbus devices on the RS485 port embedded on the RevPi Connect+.
The tutorial shows how to connect these devices to the RevPi, bt only via an USB->Modbus RTU adapter.
I would like to use the embedded RS485 port directly but couldn't find a way to do this.
On the PiCtory web page, the path is /dev/ttyUSB0 by default.
I looked in the /dev directory and /dev/ttyRS485 is shown, but it's a link to /dev/ttyUSB.
Any idea about how to change that?
Thank you in advance for your help!
Have a good day,
