I could fix the problem. Here is, what happened:
This was the problem:
all voltages inside are ok.
the yellow LAN LED is on after reset, together with green LED, green is blinking fast at start, then blinking green with short interrupts.
I can not see the Rig on my LAN Net.
The rc1258 does also not communicate over Wifi (I took the Wifi board from my rig).
I can set IP adresses over USB port with the setup-manager, I can update firmware and so on, but can not communicate in other ways "outside".
What was wrong:
All three setups which were stored inside the RRC were damaged. None of them startup the rig fully up.
How Did I found out:
I connected a serial cable to COM1 at the front side of the RRC1258.
I installed putty on my PC.
I opened a serial connection over a RS232/USB Adapter.
Settings: 38400 Baud, 8N1
There I could see, that the rig tried to start up, but it evend did not come up the LAN and Wifi setup part.
How Did I fix it?
I reseted all three setups (each one was different, and chosen by the CW Poti in the front) to the factory setting, using the setup-manager.
With the factory setup the LAN and Wifi setup worked again. From here on you can set your IP and start configuration over the internal Webpage.
I sent all three setups new to the RRC1258 via the webpage.
Problem fixed!
Thanks to Mike for his help to prevent the Rig from beeing ruined.
