HX3 ISP Programming

Updating a virgin, dead or corrupted HX3 board

In rare circumstances, HX3 will not respond to HX3 Remote app due to corrupted firmware. This might happen to a small lot of boards with so-called "fuses" not programmed correctly (my fault). In this case, HX3 may forget settings/licences or does not respond at all (dead display on HX3 Expander and MenuPanel). You may have received a DIAMEX ISP Programmer from us to update or repair HX3 boards by ISP.

Preparation

Folow the invitation to our "HX3-Firmware" dropbox. Connect DIAMEX ISP programmer to USB of your PC. Windows will ask for a driver package to install. Route it to folder "DIAMEX PROG-S/drivers/" and finish installation. Ignore complaints about drivers not certified or signed.
