Jura Ena Micro 90

[irqnet]

Is there any information about compatibility for the Ena Micro 90 model with the 7 pin connector?

I figured out the ports for VCC and GND like shown here - > http://protocoljura.wiki-site.com/index.php/Serial_interfaces

but connecting RX/TX to the specified ports has no reaction while sending a command over the web interface.

@irqnet were you able to figure out why nothing happens if you connect to the coffee machine?
I had to change the serial port from /dev/ttyAMA0 to /dev/ttyS0 for my RPi3.
Now the coffee maker just replies with what I'm sending to it.
If I connect the coffee maker ground to the RPi ground I'm unable to read anything.

You may need to use a level shifter for the data lines Jura is using 5V and the Pi is using 3V3 logic for the Data

Yes, this fixed it.
