Does factory reset on QMX(+) delete the firmware?

 

I have some QMXs and one QMX+. It is not clear to me, whether a factory reset returns the QMX(+) to the 'freshly built stage'. By that I mean: does it delete the firmware completely, so that the rig does not power up until I have installed the firmware? Of course, I can just try it and see what happens, but then I lose all my settings...

 

A factory reset does not delete the firmware. It simply returns all the settings to a factory default state.

Thank you Mike, all clear now!
I may be a language thing, because English is not my native language, but 'factory default' means to me the state that an item is in when it leaves the factory. In case of a? QMX(+) kit (i.e. yet to be built), that is without any firmware...

New QMX(+)'s leave the factory now with firmware.
A "factory reset" never did erase firmware, just reset any user settings to their factory state.

For a kit, i.e. rig yet to be built, the 'factory state' is without the firmware, hence my question...
 

Rob,

Looks like the QMX and the QMX+ are different.
In the past, all kits arrived without firmware, as you say.
Today the QMX+ kit arrives from the "factory" with the latest firmware already programmed into the processor.
The QMX kit arrives without firmware, the kit builder must install the firmware as you say.
?
My rev2 QMX+ kit arrived with firmware already installed.
I assumed the QMX did too, until I looked into this issue today and found I was wrong.

Regardless, "factory reset" only resets the user settings to their defaults,
it does not erase the firmware.? ?Admittedly, that term is a bit imprecise
even to a native English speaker.? Perhaps best to think of it as?
returning the user settings to their original state, as coded into the
firmware that was written at the "factory".

FWIW ...

There is a manual, force firmware load mode as well.
That involves jumpering on the main board for the QMX series units. The unit is then 'seen' as a flash drive on a PC and allows for copying in the firmware file.?

And you have to remember to remove the jumper after powering down otherwise the unit goes into firmware update mode again.?

All detailed in the manuals.
