In older versions of controllers, specify ports [/dev/ttyNSC0, /dev/ttyNSC1] or [/dev/ttyAPP1, /dev/ttyAPP4]. | |||
After executing these commands, special files /dev/ttyRS485-1 and /dev/ttyRS485-2 appear in the system (on the PC), corresponding to RS-485 ports of the Wiren Board. The latter command creates symbolic links to port files in /dev for convenience, which allows, for example, to use the Modbus driver configuration written for the Wiren Board on a PC without any changes. | |||
