Alternatively, download the official driver or FTDI Virtual COM Port (VCP) driver.
While the Leica TC 407 is a legacy instrument, it remains completely viable for modern workflows when paired with the proper digital pipeline. Successfully installing the hinges entirely on knowing your USB-to-Serial cable's chipset and ensuring your Windows Device Manager aligns with your surveying software's COM port configurations.
For stable data transfer, Leica recommends using cables equipped with a ferrite core near the Lemo plug.
Look for , "Prolific USB-to-Serial" , or "USB Serial Port" . Note the assigned COM port number (e.g., COM3). Configuring Leica Geo Office (LGO) or Instrument Settings The primary hurdle in connecting a Leica TC
