Hi John
Thank you for the quick reply.
We have been using that example all along, and have been able to resolve the issues now:
1) a typo in the lab network configuration not allowing the device to connect properly, and
2) we added a Gbit/s switch in front of the device (we still did not find a way to make it work with 100 Mbit/s).
For us the issue is resolved this way, and thanks again for the assistance.
Best regards,
Lukas
