PCI cards require no hardware configuration for IRQ and address allocation - this is done automatically at start up by the PC. However, the PC Velocity RS422/485 and PCI Opto Iso RS422/45 both have two sets of jumpers for configuration of RS485 multiplex modes, how to configure these jumpers is shown below.

Both jumpers shorted, causing the RXD- & TXD- and the RXD+ & TXD+ signals to short together at the 9-pin connector. The multiplex jumpers should only be set for RS485 Half Duplex operation, when one twisted pair is used to interconnect both transmit and receive lines.

    RS422/485 Information Fail Safe Open Circuit Detection Open circuit is when there are no drivers on the circuit. This occurs by design in party line multi driver/receiver systems and unintentionally when the twisted pair line is accidentally cut or disconnected or the transmitting device fails. In RS485 party line systems there are extended periods of time when none of the many possible talkers are gated onto the bus.

    PCI VELOCITY / OPTO ISO RS422/485 Optional Grounding Arrangements. Proper operation of the cable circuit, according to TIA EIA: 485 A (1995) requires that the cable ground shield is not connected directly to the equipment ground shield. A current limiting resistor should be used in series with the shield to avoid possible large current flow due to differences in ground potential.
