Communication problem PMAC2A-PC/104
#3
Ok, I checked the power supply and raised its voltage even a bit but no change yet. I'll try to measure the risetime somehow. Unfortunately the system is in use most of the time, so I can't just do changes/measurements there at any time.

Another thing occurred to me when I tried to check for voltage changes.
When I have just cold started, Device Manager shows "Delta Tau UMAC USB 2.0 Device No EEPROM" and PeWin says "no connection possible", I usually use EthUSBConfigure.exe by pressing "Store IP" and "Done". Then PMAC dissapears from Device Manager and I have to replug USB cable to find "Delta Tau PC104 USB Device". This time I just pressed the red cross for "Close" by Windows without pressing "Store IP" or "Done" and PMAC dissapeared from Device Manager again to reappear as "Delta Tau PC104 USB Device" after replugging of USB cable. How is this software working when even closing leads to a change?!?
A simple replugging of USB cable without using the software isn't changing anything of course.
