Gev189 Driver <Desktop>

The GEV189 driver is a critical software component for the Leica GEV189 (734700) USB data transfer cable, used to connect Leica total stations (such as TS02, TS06, TS09, and TPS1200 series) to a computer. The driver enables the computer to recognize the cable as a Virtual COM Port (VCP), allowing for seamless data exchange between the surveying instrument and office software like Leica Infinity or Leica Geo Office. Driver Specifications & Compatibility

  1. Device Manager – The device should appear under “System devices” as GEV189 PCI Express to I/O Bridge.
  2. Ports (COM & LPT) – Any RS-232 ports should now be visible and assignable.
  3. Event Viewer → Windows Logs → System: Filter for “GEV189” – no errors should appear.
  4. Benchmark test – Use a loopback test on a serial pin (e.g., connecting TX to RX on a DB9 port) and run Portmon or Termite to confirm data flow.
  1. Extract downloaded driver files to a folder (e.g., C:\Drivers\GEV189).
  2. Open Device Manager → find the unknown device.
  3. Right-click → Update driver → Browse my computer for drivers.
  4. Navigate to the folder containing GEV189.inf.
  5. Click Next → If a “Windows can’t verify publisher” warning appears, select Install this driver software anyway.
  6. Reboot.

Hardware Interface: Acts as the essential bridge between your PC's operating system and the Leica Total Station, allowing the computer to recognize the hardware as a valid connection. gev189 driver

5. Replacement and Alternatives

The original GEV189 is not a stocked item at major distributors (Mouser, DigiKey, RS). However, three practical paths exist:

  • In Device Manager, click View > Show hidden devices.
  • Look for any grayed-out entries related to "GEV189," "Sensor Hub," or "I2C Host Controller."
  • Right-click and Uninstall device (check "Delete driver software" if available).
  • Reboot and reinstall the fresh driver.

C. Output FET burnout

  • Symptom: Short circuit between motor phase A and ground.
  • Cause: A stalled motor or a miswired winding exceeding 3 A for >100 ms.
