Wow - that is what we expected - it seems the solution is found
I think this happened to you (and some other users having problems with updates over USB):
- during the update the powerbar switches off the sockets (after 30s this will happen due to security reasons)
- when switching off the connected devices a voltage peak in the main line occurs
- this results in disturbances in the USB line -> ProfiLuxControl can`t communicate with ProfiLux and that`s ist - update failed
Why does this only happen in some cases - why are other customers able to update successfully?
I believe there are 2 reasons:
1. this depends on the load which is switched off during the update - a chiller or MH ballast will cause much electrical noise, a simple solenoid won`t
2. a notebook can be disturbed easier than a desktop PC - because the PC is grounded and electromagnetic noise is forwarded to PE (protecting earth)
Bottomline:
Before updating the ProfiLux firmware with USB you should unplug the control lines between ProfiLux and the powerbars and wait until they switched to the "no connection state"!!!
I reed this and just update my 3ex to 5p.
Plug & play, many thanks guys!
