2.1 RS-232 interface
4 channels，support the highest-level baudrate 115200bps. The corresponding interface in Linux system is COM1 ~ COM4. Specially COM1 and COM2 have 2 output type as RS-232 and RS-485.
2.2 RS-485 interface
| The corresponding port in Linux system is COM1、COM2, and same UART port with RS-232 ( COM1/COM2), but different output type. Also, a 120 ohm(Ω ) terminal Resistance inside. |
2.3 CAN Bus interface
The function of Can-bus interface is optional. Also, a 120 ohm(Ω) terminal resistance between CAN+ and CAN- .
2.4 Power interface
