Unlike modern total stations that support Bluetooth or Wi-Fi, the Leica TC 407 communicates via a . To transfer data (coordinates, survey points, or firmware updates), you need a specific piece of software bridge: the LEICA TC 407 driver .
If you have ever searched for this driver, you have likely encountered outdated GeoCom links, cryptic forum posts, or complete dead ends. This article will demystify everything about the Leica TC 407 driver—what it is, where to get it, how to install it, and how to fix common connection errors. First, a critical clarification: There is no single "LEICA TC 407 driver" file from Leica Geosystems that magically makes the TC 407 work with any software. Instead, the "driver" refers to a combination of two things: 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. 2. The Communication Protocol (GeoCOM) The Leica TC 407 speaks GeoCOM (Leica’s proprietary communication protocol). Your surveying software (e.g., Leica SurveyOffice, AutoCAD Civil 3D, Carlson SurvCE, or even custom scripts) must include a GeoCOM driver or a serial emulation layer. When people say “installing the TC 407 driver,” they often mean configuring GeoCOM on their PC. LEICA TC 407 driver
A: No – the TC 407 transmits 8-bit data. The driver is the USB adapter’s driver, which is 64-bit capable. GeoCOM itself is 32-bit but runs fine on 64-bit Windows. Unlike modern total stations that support Bluetooth or
Thus, solving the driver puzzle requires . Part 2: Where to Download the Correct Drivers Since Leica Geosystems has discontinued the TC 407 (replaced by the TC 800 and later TS series), the official support page no longer offers a dedicated “driver installer.” Here is your practical sourcing guide: A.
