Product Information

Full details

The Lenovo 47293 PCIe expansion card is designed for IT professionals and industrial engineers who require reliable serial communication in their workstations or server environments. This card provides four independent RS422/485 ports, enabling seamless connectivity for legacy equipment, industrial controllers, or data acquisition devices. Its low-profile architecture makes it an ideal solution for compact chassis configurations, though users should ensure their motherboard has an available PCIe slot and sufficient clearance for card installation.

Extended Product Information

FAQs

Can this card be used in a standard full-height desktop case?

Yes, though it is designed for low-profile slots, it can be adapted to full-height cases using a standard mounting bracket.

Does this card support RS232?

No, this specific model (47293) is strictly designed for RS422 and RS485 communication protocols.

Do I need to install specific drivers?

Most modern Windows environments will detect the card automatically, but you may need to download the latest drivers from the official Lenovo support site for optimal performance.

Is this compatible with non-Lenovo motherboards?

The card uses the standard PCIe interface and should be compatible with most motherboards that support the required PCIe generation.

What is the maximum distance for RS485 communication?

RS485 can typically support distances up to 1,200 meters, depending on cable quality and data transmission speed.

Troubleshooting

Ports are not detected by the operating system

Verify the card is fully seated in the PCIe slot and check the Device Manager for missing drivers or hardware flags.

Communication errors with connected serial devices

Ensure that the RS422/485 wiring configuration matches the device requirements and check that terminal resistors are correctly set if required.

System fails to boot after installation

Remove the card and attempt to boot to confirm the system's stability, then re-seat the card in a different PCIe slot if available.

Pros and Cons

Pros

  • Adds four serial ports to systems lacking them natively
  • Compact low-profile design fits in restricted spaces
  • Reliable high-speed data transmission for industrial equipment
  • Direct compatibility with Lenovo workstation architectures

Cons

  • Not suitable for consumer devices without serial requirements
  • Requires an open PCIe slot on the motherboard
  • May require specific driver configuration depending on the operating system

Setup, Compatibility & Care

To install the card, ensure the workstation is powered down and disconnected from the AC power source. Remove the side panel of the chassis, locate an available PCIe slot, and remove the corresponding backplane bracket. Gently insert the card until it is seated firmly, then secure the bracket with a screw. Once installed, reboot your system.

Compatibility is primarily dictated by the availability of an open PCIe slot and the system's ability to support serial communication protocols at the OS level. Always keep the contact pins clean and free of dust. If the card is removed for maintenance, store it in an anti-static bag to prevent electrostatic discharge damage.
