    How to set up B&B PCI Card for RS-232/422/485 operation?
    • S
      Sarah DeleonJul 31, 2025
      To ensure correct operation, configure your B&B PCI Card for the appropriate mode (RS232, RS-422, or RS-485 2-wire or 4-wire). Use the DIP switches on the card and the Advanced Port Settings to make these adjustments.

      Power down your computer, then remove and re-insert the B&B PCI Card. You might also try a different slot. Ensure that your system is configured for PnP OS.

    What to check if there is a mismatch in RS-422 or RS-485 pinouts on B&B PCI Card?
    • L
      laura02Aug 15, 2025
      Verify your pinouts. In RS-422 or RS-485 mode, the 'A' lines should correspond with your 'A' or '-' lines, and 'B' lines should correspond with your 'B' or '+' lines.

    Robin BerryAug 19, 2025
    What to do if there is no response from devices in RS-485 mode with B&B 3PCIU2 PCI Card?
    • S
      Sharon JohnsonAug 20, 2025
      Some manufacturers might label their data connections for A and B in reverse of the RS-422 or RS-485 standard, where the A line is (+) and the B line is inverted (-), following the IC standard. In this case, swap the wires and test again.

    What to do if I'm having software issues bypassing Windows drivers with my B&B 3PCIU2?

      Try using an alternative software package for troubleshooting purposes.
