GND GND GND GND 2-Wire RS-485 Port Signal GND GND GND GND 2.3 Jumper Settings For RS-422/485 serial communications, when an electrical signal travels through two different resistance junctions in a transmission line, the impedance mismatch will sometimes cause signal reflection. Signal reflection causes signal distortion, which it turn will contribute communications errors. - Page 10 same impedance at the line ends as in the line itself by terminating them with resistors Ideally, the two ends of the cable will have a termination resistor connected across the two wires. Without termination resistors, reflections of the fast driver edges can cause multiple data edges that can cause data corruption.
- Page 11 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.

2.4.2 Installation for Linux 2.6.x/3.x Please refer to the installation guide and driver for Linux 2.6.x & 3.x operation system installation within the folder located in the CD driver. :\Driver\PCIe\Linux Chapter 3: Troubleshooting Tips Some or all of the ports will not communicate with any devices Please refer to following instructions to configure Serial COM settings. - Page 15 On the “Settings” tab, please set the mode to “RS422/485” and choose RS485 buffer enable to “Active High”. Click “OK” to approve the setting for the selected port. Set the other port (e.g. COM8) by the same procedures mentioned. System fails to find the PCI Express serial board or COM port It may cause by following issue: The board is not properly plugged into the PCI Express slot.
- Page 16 IRQ setting is available in the PCI/PnP settings. The board itself might be defective. You can try another mainboard testing this board working or not. There are some exclamation marks in device manager and serial ports can not work properly It caused by the wrong driver installing or hardware setting.
