Configuration:
On the web pages of qDSLRDashboard you find the required firmware to flash and a detailed description. Has worked for me without any problems, the device was then used without further configuration.
Mounting:
If I need it, I fix the router 3mm Perlon Cord so the camera body, that it rests flat on the rear display. This goes well with Einmachgummis, but does not look so great. The small box is nowhere in the way and I do not need bulky attachments on the hot shoe.
