2.1 RS-232 interface

4 channels  support the highest-level baudrate 115200bps. The corresponding interface in Linux system is COM1 ~ COM5. Specially COM1 and COM2 have 2 output type as RS-232 and RS-485,  COM5 has 2 output type as RS-232 and CAN .

2.2 RS-485 interface

The corresponding port in Linux system is COM1/COM2 ,which is same UART port with COM1/COM2 of RS-232 interface. 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- .
