JP1 has been mounted, sorry was faulty information.
But finaly i found the problem: 5V GND was not connected
to the UniPI power plug, only on the mini USB.
Thank's for you help.

I measured the voltage on the pinout of UniPI without the cable,
that's what i've done.
Only the UniPI is connected to the power, i want to avoid the
dual sourced power.
The cables to the DR-15-5 are also ok.
Do you have the same effect ?

The 2.1mm plug is from you and is connected to the DR -15 -5, so it should run,
but i don't have an extra power supply with the 2.1mm plug.
I measured the voltage between ping 2-6 and 4-6. There is always 0V with and
without JP1 mounted or not. So i think the problem lies on the Unipi, not the cable.
Does it run on your side with Unipi and Raspi3 on single power source ?

Hi Tomas,
that's exactly as i connected the cable. That seem's to be ok, as everything else
(setting/resetting inputs and outputs) does work if i connected the power to
the pi over the mini-USB port.
Could you give me the Pins, where the 5V and GND should lie on ?

Michael
Hi Thomas,
today i received 1 more UniPi+Raspi 3. It show's the same effect.
Is it right, that there is only 1 cable between the 2 unit's, only the
flat cable ?
Should on the Raspi 3 be an LED on, if i connect power to the
UniPi ?
Which one are the 5V and GND pin's ? I am more the software man ...
best regards,
Michael
Hi,
i try to connect the UniPi together with the Raspberry Pi 3 on Singe Power Source,
Jumper JP1 mounted. The UniPi hangs on an Meanwell DR -15 -5 .
Connecting the Power on does not powering on the RPi 3, nothing happens.
If i unmount JP1 and connect an extra Micro USB Cable to the Meanwell DR-15-5,
it work's.
Is Single Power Mode not availiable anymore ?
best regards
Michael
