2-Wire RS485 working model with termination resistor:

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. Note: Stands for termination resistor

near the receiving side.

Factory default jumper setting is OPEN (Disable 120 ohms termination

resistors across the two wires)

J1 (J2/J7/J8): RS-422/485 Mode Selector

1). Auto RS-422/485 (Default)

This COM port can automatically detect the state of RS-422 full
