Leica Tc 407 Driver May 2026

Technical Report: Leica TC407 Connectivity and Drivers The Leica TC407 (part of the TPS400 series) is a legacy total station that requires specific hardware and software configurations for data transfer to modern computers. Because the TC407 primarily uses a serial interface, "drivers" typically refer to the USB-to-Serial cable drivers rather than the instrument itself. 1. Essential Driver and Hardware Components

To connect a Leica TC407 to a PC, you must identify the cable being used:

GEV102 Cable (RS232): This is a 5-pin Lemo to 9-pin RS232 serial cable. If your PC has a native serial port, no driver is required.

GEV189 / GEV267 USB Cables: These are integrated USB-to-Serial cables. They require specialized drivers (often based on the FTDI (FT232R) or Prolific chipsets) to create a virtual COM port on Windows.

Generic USB-to-Serial Adapters: If using a GEV102 cable with a third-party USB adapter, you must install the driver specific to that adapter's manufacturer. 2. Official Software for Data Exchange

Connectivity is managed through Leica-specific office software, which acts as the interface for the driver's COM port:

Leica Survey Office: The original legacy software specifically designed for the TC407 series. LEICA TC 407 driver

Leica Geo Office (LGO) / LGO Tools: The successor to Survey Office, frequently used for downloading GSI (raw data) or ASCII files from the TPS400 series.

Leica Infinity: The modern replacement for all legacy office software, which supports data processing for most Leica total stations. 3. Installation and Configuration (Windows 10/11) To ensure the driver and instrument communicate correctly:

Cable Driver Installation: Download drivers from official sources like Leica myWorld or reputable repositories. In Windows Device Manager, the cable should appear as a "USB Serial Port (COMx)".

Instrument Communication Settings: On the TC407, navigate to settings and match the PC's COM port parameters. Standard defaults are: Baud Rate: 19200 (or 115200 for newer models). Data Bits: 8. Parity: None. Stop Bit: 1.

Data Exchange Manager: Open your Leica software, select "Data Exchange Manager," and choose the corresponding COM port to view the "Jobs" directory on the instrument. 4.

Introduction

The Leica TC 407 is a total station, a surveying instrument used to measure distances, angles, and coordinates in various fields such as construction, engineering, and geography. To function properly, the Leica TC 407 requires a driver, a software component that enables communication between the instrument and a computer. The Leica TC 407 driver plays a crucial role in facilitating data transfer, configuration, and control of the total station. This essay provides an overview of the Leica TC 407 driver, its functions, and its significance in the surveying industry.

Functions of the Leica TC 407 Driver

The Leica TC 407 driver is responsible for several key functions, including:

  1. Communication: The driver enables communication between the Leica TC 407 and a computer, allowing users to transfer data, configure the instrument, and control its functions.
  2. Data Transfer: The driver facilitates the transfer of measurement data from the total station to a computer, where it can be processed, analyzed, and stored.
  3. Instrument Configuration: The driver allows users to configure the Leica TC 407's settings, such as the measurement units, coordinate system, and datum.
  4. Error Handling: The driver provides error handling and debugging capabilities, enabling users to troubleshoot issues and resolve problems.

Significance of the Leica TC 407 Driver

The Leica TC 407 driver is essential for several reasons:

  1. Increased Productivity: The driver streamlines the data transfer process, reducing the time and effort required to transfer measurement data from the total station to a computer.
  2. Improved Accuracy: The driver ensures that data is transferred accurately and reliably, minimizing the risk of errors and inconsistencies.
  3. Enhanced Flexibility: The driver provides users with flexibility in terms of instrument configuration and data processing, enabling them to adapt to changing project requirements.
  4. Compatibility: The driver ensures compatibility between the Leica TC 407 and various software applications, such as surveying and mapping software.

Conclusion

In conclusion, the Leica TC 407 driver is a critical component of the Leica TC 407 total station, enabling communication, data transfer, and instrument configuration. Its functions and significance are essential to the surveying industry, as it increases productivity, improves accuracy, and enhances flexibility. The Leica TC 407 driver plays a vital role in ensuring that the total station operates efficiently and effectively, making it an indispensable tool for surveyors and engineers.

I notice you’re asking for a review of a LEICA TC 407 driver — but there’s an important clarification to make first.

Leica Geosystems (known for surveying equipment) does not manufacture a “TC 407” model. The closest match is the Leica TC407 (part of the older TC400 series of total stations). If that’s what you mean, then the “driver” typically refers to:

Assuming you’re referring to using a Leica TC407 total station with modern software via a serial or USB driver, here is a detailed, practical review:

Warning: Many cheap eBay/Amazon cables use counterfeit Prolific chips. Windows may show “Code 10” error. If that happens, buy an FTDI-based cable such as the TRENDnet TU-S9 or StarTech ICUSB232FTN.

Part 4: Common LEICA TC 407 Driver Problems & Fixes

1. The Windows Serial (COM Port) Driver

When you connect your TC 407 to a PC using a serial-to-USB adapter (since modern laptops lack 9-pin serial ports), Windows needs a driver for that adapter chipset (e.g., Prolific PL-2303, FTDI FT232, or Silicon Labs CP210x). Without this, the device won’t appear as a COM port.
