The production of Unipi Axon controllers was discontinued. The Axon line was replaced by the next generation named Unipi Patron.

Axon serial port maps

See the table below to find out how the physical RS485/RS232 serial port lines are mapped into Linux ports within /dev/.

Alternatively, all serial ports with N (eg. /dev/ttyNS0) mentioned below are also accessible via /dev/extcomm/X/Y, where X is the number of section, and Y is the number of the serial port.

All those ports are also accessible via section number 0 in /dev/extcomm/0/Z.

USB converters (FTDI, CH34x, PLxxxx and CPxxxx) are also supported by default. For using other gateways or devices, installation of drivers is necessary.
