HX3 Flash

HX3 Flash for Windows application (named HX3_flash.exe in Github LATEST ZIPs) is a "one click solution" to update your HX3 mk2/mk3/mk4 board or expander. You will need an HX3 Expander equipped with USB port, or an USB adaptor cable FTDI TTL232R 5V, or any USB to serial converter based on FTDI FT232R chipset.

Download one of the following ZIPs appropriate for your Instrument:

Unzip archive contents to a local folder on your hard disk. It will contain all files needed to update your HX3.

Note: USB-serial adaptors of other makes will not work with HX3 Update. Automatic update functions require installed HX3 firmware #3.51 and up. HX3 Flash will update HX3 boards and expanders with responding firmware, even with corrupted FPGA images or faulty behaviour. In this case, uncheck all Restore checkboxes prior to Update click.
