Serial (COM) Port
COM
COM:
RS232 or UART5
The system unit is equipped with one onboard serial COM port at the bottom side. This COM
port is fixed at RS232 or UART5 via the setting of JP11 and JP12 which must be set simultane-
ously.
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.
Important:
You need to set JP11 and JP12 simultaneously.
