Download page for the PEAK-System device driver setup (Windows). Pick the latest "Device Driver Setup for Windows".
Drivers you usually need for AgOpenGPS hardware — PCAN adapters and USB-Serial adapters.
Most AgOpenGPS setups talk to the tractor or implement through one of two interfaces:
Official driver package for PEAK-System PCAN-USB adapters (and clones that use the same chipset). Required by the AOG Task Controller, Virtual Terminal and most CAN tools on Windows.
FTDI CDM driver for FT232 / FT2232 / FT4232-based USB-to-Serial adapters. Install this if Windows does not recognise your USB-RS232 dongle, or if the COM port disappears.
