Gev189 Driver Link

The Leica GEV189 driver is a specialized utility required to establish a communication link between a Windows PC and Leica surveying instruments, such as total stations and digital levels, via the GEV189 USB data transfer cable. This driver creates a virtual COM port that allows office software like Leica Infinity or Leica Geo Office to "see" the instrument for data synchronization. Driver Specifications & Compatibility

The driver is essential for the GEV189 (Part Number 734700) cable, which features a Lemo 5-pin connector on one end and a standard USB-A connector on the other. GEV189 734700 USB Data Transfer Cable For Leica

Part 7: Alternatives and Community Support

If you cannot locate an official GEV189 driver, consider these alternatives: gev189 driver

  1. Generic PCI Multi-I/O driver – Some GEV189 hardware is compatible with the Moschip MCS98xx or Oxford Semiconductor OXPCIe954 driver set. Try force-installing the INF for those chips (backup first).
  2. Legacy driver archives – Websites like VOGONS Drivers or Retro PC Drivers maintain user-uploaded copies. Proceed with caution.
  3. Reverse-engineered Linux driver – The Linux kernel community has a staging driver called staging/gevpci. Activate it via make menuconfig → Device Drivers → Staging → GEV PCI support.

4. Configuration and Best Practices

For industrial cameras, proper configuration is vital.

A. Jumbo Frames (MTU) The GEV189 driver works best when Jumbo Frames are enabled to reduce CPU overhead. The Leica GEV189 driver is a specialized utility

  1. In Device Manager, right-click your NIC > Properties.
  2. Go to the Advanced tab.
  3. Look for Jumbo Frame or MTU.
  4. Set this to the highest value supported (usually 9014 Bytes).
    • Note: You must also set the camera to use a packet size matching this MTU (usually just under 9000 bytes) via the camera management software.

B. Receive Side Scaling (RSS) While the GEV189 driver optimizes traffic, ensure your NIC settings allow for high throughput.

Clean Uninstall

Leaving residual driver files can cause conflicts if you later switch hardware. Part 7: Alternatives and Community Support If you

  1. Open Device Manager → right-click GEV189 device → Uninstall device.
  2. Check Delete the driver software for this device.
  3. Run pnputil /delete-driver oemXX.inf (replace XX with the correct number from pnputil /enum-drivers).
  4. Delete any leftover GEV189.sys from C:\Windows\System32\drivers.
  5. Reboot.

Direct Download Steps (Windows)

  1. Visit the Advantech Support Center (if your motherboard is Advantech).
  2. Search “GEV189” or “multi-I/O driver pack”.
  3. Filter by your OS (Windows 7, 8.1, 10, 11, or Embedded).
  4. Download the .exe or .zip package labeled “GEV189 PCIe Bridge Driver v3.2.1” (version numbers vary).
  5. Alternate: Use the GEV189 Driver Assistant Tool (a lightweight utility that queries the hardware ID and fetches the correct INF file).

Checksum verification: After downloading, compare the SHA-256 hash with any published value on the OEM’s site. A mismatch indicates tampering or corruption.
