Chapter 4 Ports and Connectors

Chapter 4

Serial (COM) Port

The system board is equipped with a 9-pin connector for connecting an external serial COM

port (COM 1). COM port 1 will vary according to JP4’s setting.

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. To connect COM 1, please refer to the following description. The serial port may

be mounted on a card-edge bracket. Install the card-edge bracket to an available slot at the

rear of the system chassis then insert the cable connector to the 9-pin connector. Make sure

the colored stripe on the ribbon cable is aligned with pin 1 of the connector.
