G11 no handshake with MD4-7 with Iqn Sync and GSM or Tablet

Hello there,

We purchased two new MR4-7 modules with firmware and Iqan design version 4.03xx. We updated both modules with a machine clone file to version 4.07.7.1413 using Iqan run.

Then we tried to connect with the G11 to the MD4-7 with GSM and Iqan Syn. It was possible to select the machine ID to connect to. After that Iqan sync give a message: no handshake. 

The G11 led was blinking 4xred 2xyellow = Internal errror/G11

We tried with Iqan run for tablets and the problem was the same.

After that, we updated the MD4-7 with the same aplication using Iqan design to version 4.07.15 and then with iqan run back to the clonefile to version 4.07.7 and then the G11 was working correct.

What goes wrong?

Kind regards Laura
