Serial port maps
See the table below to find out how the physical RS485 serial port lines are mapped into Linux ports within /dev/.
Neuron
Alternatively, all serial ports 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.
| RS485-1.1 | RS485-2.1 | RS485-3.1 | GSM | |
|---|---|---|---|---|
| S103 | ttyNS0 | x | x | x |
| S103-G | ttyNS0 | x | x | ttyAMA0 |
| M103 | ttyNS0 | x | x | x |
| M203 | ttyNS0 | x | x | x |
| M303 | ttyNS0 | x | x | x |
| M403 | ttyNS0 | x | x | x |
| M503 | ttyNS0 | ttyNS1 | x | x |
| M523 | ttyNS0 | ttyNS1 | x | x |
| L203 | ttyNS0 | x | x | x |
| L303 | ttyNS0 | x | x | x |
| L403 | ttyNS0 | x | x | x |

| L523 | ttyNS0 | ttyNS1 | x | x |
| L513 | ttyNS0 | ttyNS1 | ttyNS2 | x |
| L533 | ttyNS0 | ttyNS1 | ttyNS2 | x |
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 |
| USB3 | /dev/serial/by-port/2 |
| USB4 | /dev/serial/by-port/3 |
