RS232/422/485
The serial COM port is RS232 asynchronous communication port with 16C550A-compatible
UARTs that can be used with modems, serial printers, remote display terminals, and other se-
rial devices.
The system unit is equipped with 1 onboard serial port at the top side. JP6 is used to config-
ure the COM port 2 to RS232, RS422 (Full Duplex) or RS485. The pin functions of the COM
port will vary according to the jumper’s setting.
The amplify left and right connectors which have amplifying features are used to connect
external speakers.
