This RS-422/485 PCI Express Serial board equips
independent TX and RX termination resistors for
each serial port. User can modify the jumper
setting (short the pins) to avoid impedance
mismatched problem when operate under Multi-
drop transmission. Resistors should be added
near the receiving side.

1. Pin 1-2 jumper setting is short by default,
Auto Detect / RS-485(2-Wire)
This COM port can automatically detect
the state of RS-422 full duplex or RS-485
half duplex and control the data
transmitting and receiving wires at the same
port.
2. Pin 2-3 jumper setting is short for RS-422/
RS-485(4-Wire)
This COM port forces to run RS-422 full
duplex mode.
