Gev189: Driver Repack

Leica GEV189 (Part No. 734700) is a specialized USB-to-Lemo data transfer cable used to connect Leica total stations (like the TS02, TS06, TS09, and TPS1200 series) and digital levels (DNA series) to a computer. Leica Geosystems Essential Driver Info The GEV189 cable uses a Prolific PL2303

Leica Geosystems frequently updates their drivers to maintain compatibility with new versions of Windows (such as Windows 10 and 11). There are two primary ways to get the official software: gev189 driver

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 Leica GEV189 (Part No

• Type A (Common): A bipolar stepper motor driver for micro-positioning stages (e.g., in wafer inspection tools or medical sample handlers).
• Type B (Less common): A differential line receiver/driver for incremental encoders, translating raw A/B quadrature signals into TTL-level logic for a motion controller.

• Is this for a nuclear physics experiment?
• Is “gev189” written on a piece of hardware you have?
• Do you need the driver circuit design or software driver?

3. Common Failure Modes

Field data from three industrial service centers (2024–2025) pinpoints four recurrent issues with GEV189 drivers:

Where to find it: If you don't have the original disk, drivers are often available through authorized dealers like SCCS Survey or Leica Geosystems.

The GEV189 is a specific USB data download cable (part number 734700) featuring a 5-pin Lemo connector on one end for the instrument and a USB connector for the PC. Because the cable contains internal electronics that convert USB signals to serial data, the computer requires a dedicated driver to recognize it as a "Virtual COM Port". Common Challenges & Solutions
