Serial port mapping
See the table below to find out how the physical RS485/RS232 serial port lines are mapped into Linux ports within /dev/.
Patron
Alternatively, all serial ports with N (eg. /dev/ttyNS0) mentioned below are also accessible via /dev/extcomm/Y/X, where Y is the number of section, and X is the number of the serial port. X and Y are counted from 0.
| RS485-1 | RS232(485)-2 | RS485-3 | RS485-4 | |
|---|---|---|---|---|
| S107 | ttyNS0 | ttymxc1 | ttymxc0 | x |
| S117 | ttyNS0 | ttymxc2 | ttymxc1 | ttymxc0 |
| S167 LTE | ttyNS0 | ttymxc0 | x | x |
| S207 | ttymxc0 | x | x | x |
| RS485-1.1 | RS232(485)-1.2 | RS485-1.3 | RS485-2.1 | |
|---|---|---|---|---|
| M207 | ttyNS0 | ttymxc1 | ttymxc0 | x |
| M267 LTE | ttyNS0 | ttymxc0 | x | x |
| M527 | ttyNS0 | ttymxc1 | ttymxc0 | ttyNS1 |
| M567 LTE | ttyNS0 | ttymxc0 | x | ttyNS1 |
| L207 | ttyNS0 | ttymxc1 | ttymxc0 | x |
| L527 | ttyNS0 | ttymxc1 | ttymxc0 | ttyNS1 |
USB ports
USB converters (FTDI, CH34x, PLxxxx and CPxxxx) are also supported by default. For using other gateways or devices, installation of drivers is necessary.
| USB1 | /dev/serial/by-port/0 |
| USB2 | /dev/serial/by-port/1 |
