COM 1: RS232/422/485
COM 2: RS232
COM 2, COM 4, COM 5 and COM 6 are fixed at RS232.
The pin functions of COM port 1 and COM port 3 will vary according to jumpers’ setting. These
jumpers allow you to configure the Serial COM ports to RS232, RS422 (Full Duplex) or RS485.
JP1, JP2 and JP4 are used to configure the Serial COM port 1. JP7, JP8 and JP12 are used to
configure the Serial COM port 3. Refer to “COM 1/COM 3 RS232/422/485 Select” and “COM 1/
COM 3 RS232/Power Select“ in this chapter for more information.
The serial ports are asynchronous communication ports with 16C550A-compatible UARTs that
can be used with modems, serial printers, remote display terminals, and other serial devices.
