The Leica TC 407 speaks (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
The TC407 communicates via GSI (Geo Serial Interface) , a standard format for exchanging survey data. The instrument can output data in GSI-8 or GSI-16 formats. The MASK settings control which specific data fields (e.g., point ID, coordinates) are included. Setting the wrong parameters can lead to data being misinterpreted. Last updated: October 2025
