Technical Report: Leica TC407 Connectivity and Drivers The (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
The total station does not use a standalone "driver" for the device itself; instead, connectivity depends on a USB-to-Serial data cable and the associated ProLific or FTDI cable drivers . 1. Cable Driver Installation Leica TC407 units connect to modern PCs via a 5-pin Lemo-to-USB cable. Identify the Chip : Most cables use either the ProLific PL2303 Go to product viewer dialog for this item. or FTDI FT232R Go to product viewer dialog for this item. chipset. LEICA TC 407 driver
A: Newer Leica instruments use a 5-pin LEMO connector and different voltage levels (RS-422 vs RS-232). The TC 407 requires true RS-232 at ±12V. Some modern cables are TTL (0-3.3V) and will not work. Leica TC407 Technical Report: Leica TC407 Connectivity and
