Usb Download Cable Gev189 Driver Windows 10 Upd [extra Quality] [480p 4K]
The Leica GEV189 USB download cable (Part No. 734700) is a critical link for surveyors, enabling high-speed data transfer between Leica Total Stations (such as the TS, TCRP, and DNA series) and a PC. While Windows 10 often handles USB devices automatically, the GEV189 frequently requires specific driver installation to be recognized as a Virtual COM Port (VCP).
Below is a guide on where to find the latest updated drivers and how to install them on Windows 10. 1. Where to Download the GEV189 Driver
Official and reliable sources for the GEV189 driver include:
Leica myWorld: The primary source for official, verified drivers is the Leica myWorld portal.
Third-Party Vendors: Many equipment specialists provide mirrors for these drivers, such as the Sunbelt Sales Support Page which hosts versions for GEV189, GEV195, and GEV218.
FTDI Chipset Drivers: Because the GEV189 cable typically uses an FT232R chip, you can often use the universal VCP Drivers from FTDI if the standard Leica installer fails. 2. Windows 10 Installation Steps
If Windows 10 does not automatically assign a COM port when you plug in the cable, follow these manual installation steps:
Extract the Driver: Download the driver ZIP file and extract it to a known folder on your PC.
Access Device Manager: Right-click the Start button and select Device Manager.
Locate the Device: Look for "FT232R USB UART" or "Unknown Device" under Other devices. Update Driver: Right-click the device and select Update driver. Choose "Browse my computer for drivers". usb download cable gev189 driver windows 10 upd
Navigate to your extracted folder. If the folder specifically mentions Windows 7 or 8, select it anyway; these versions are typically compatible with Windows 10.
Confirm Port Assignment: Once installed, the device should appear under Ports (COM & LPT) as "USB Serial Port" or "GEV189 Download Cable". 3. Troubleshooting Common Issues
"Driver not passed Windows Logo testing": During manual installation, Windows may show a security warning. Select "Continue Anyway" to proceed.
Missing COM Port: If the cable is listed under "Universal Serial Bus Controllers" but not under "Ports," you may need to repeat the "Update Driver" process specifically for the USB Serial Port entry that appears after the first stage of installation.
Cable Not Recognized: Ensure you have administrative privileges. Security software or firewalls can sometimes block the installation of unsigned legacy drivers.

The Leica GEV189 (734700) USB download cable is fully compatible with Windows 10. While earlier versions of the driver were designed for Windows XP and 7, modern installations on Windows 10 typically use updated FTDI or Prolific chipset drivers to enable data transfer between Leica total stations and PCs. Download Sources for GEV189 Drivers
Official and verified third-party repositories provide the necessary ZIP files for Windows 10:
G2 Survey: Offers a combined driver package for GEV189/GEV195/GEV218 as part of their Software Downloads section.
Sunbelt Sales: Provides the v1.70 ZIP (3 MB) specifically for GEV189/GEV195/GEV218 Cable Drivers. The Leica GEV189 USB download cable (Part No
Leica MyWorld: The official Leica Geosystems customer portal is the primary source for the most recent, digitally signed drivers. Installation Guide for Windows 10
If the driver does not auto-install via Windows Update, follow these manual steps:
Extract the Files: Download the driver ZIP from one of the sources above and extract the contents to a known folder.
Access Device Manager: Plug in the GEV189 cable. Open Device Manager, find the device (often listed as FT232R USB UART or similar), right-click it, and select Update Driver.
Manual Search: Choose "Browse my computer for drivers" and navigate to the extracted folder. Even if the folder is labeled for "Windows 7" or "Windows 8," these files generally work for Windows 10.
Confirm Installation: Once finished, the cable should appear under Ports (COM & LPT) as a USB Download Cable or Serial USB Converter with an assigned COM port number.
Handling "Unsigned" Warnings: If a "Windows Logo testing" warning appears, select "Continue Anyway" to complete the setup. Technical Specifications
Connector Type: USB to 0B 5-pin male (compatible with LEMO).
Compatibility: Supports Leica TS02, TS06, TS09, TPS1200, and DNA digital levels. Step 5: Test in Your Programming Software Open
Functions: Facilitates both uploading and downloading of survey data between the instrument and the PC.
Step 5: Test in Your Programming Software
Open your software (e.g., GE Proficy Machine Edition, Cimplicity, or Schneider Somachine).
- Select the correct COM port number from Device Manager.
- Set baud rate to match the target device.
- Try to "Go Online" or "Read PLC" .
If you still get a connection timeout, try a different USB port (USB 2.0 ports work more reliably than USB 3.0 for these old cables).
Q4: My programming software says “Access denied” to COM port.
A: Run your programming software as Administrator. Also ensure no other software (like a terminal emulator) has the port open.
Why Windows 10 Update Breaks the GEV189 Driver
You may have had the cable working perfectly, but after a recent Windows 10 update, it stopped. Here’s why:
- Driver Signature Enforcement: Windows 10 requires digitally signed drivers. Many older GEV189 drivers lack a valid signature.
- Prolific Chipset Issues: Most GEV189 cables use a counterfeit Prolific PL-2303HX chip. Official Prolific drivers (v3.3.x and above) deliberately disable counterfeit chips, showing an error:
Code 10 – This device cannot start. - CH340/341 Conflict: Some GEV189 cables use the CH340G chip. While more reliable, Windows 10 updates sometimes overwrite the correct .INF file.
The key phrase "usb download cable gev189 driver windows 10 upd" is critical because users need a driver that survives Windows updates and works with potentially counterfeit hardware.
Step 1: Identify the Chip Inside Your GEV189 Cable
Plug the cable into a USB port. Open Device Manager (right-click Start button > Device Manager). Look under:
- Ports (COM & LPT) – if lucky, you’ll see “USB Serial Port (COMx)” with a yellow triangle.
- Universal Serial Bus controllers – look for an unknown device.
Right-click the problematic device > Properties > Details > Hardware Ids. Note the VID_ and PID_ values:
VID_067B PID_2303= Prolific PL-2303VID_10C4 PID_EA60= Silicon Labs CP210xVID_1A86 PID_7523= Chinese CH340
Most GEV189 cables use Prolific PL-2303 HX/HXD/EA variants.
A Note on Hardware Quality
Let’s be real: Many $10 GEV189 cables from eBay or Amazon use counterfeit Prolific chips. Windows 10 is particularly hostile to them. If you’ve spent 45 minutes fighting driver errors, consider:
- Buying a genuine GEV189 from a known automation supplier (expensive, but works).
- Or using an FTDI-based USB-to-RS485/RS422 cable with an adapter—FTDI chips are bulletproof on Windows 10/11.
