Hey guys thanks that you try to help me!
I owe you some more details:
In the moment the miner is working since 22 hours together with my other miners. I have full access to him over the webinterface. Better to say: He is working 100% like any other miner, I have yesterday even changed the firmware to the latest from 9.1.2015.
If the miner is up one time, he is running well!
But the problem appears when Im turning off while unplug/turn off the PSU
Without the contact (say stand-alone) to my PC or Netbook (that must be powered from the wall !!! too) he is not be able to start again.
So to me as a non expert it looks like there is not enough Power-Ground. But this little connection from the serial ports with a other device powered by circuit is the little bit that is needed to start.
Once it started and the network led on the miner becomes green I can remove the serial connection and keepit running.
With less words: If the miner is running I can do all the things I want, even reboot, flashing new firmware,make changes in pooll settings...all works like it should be.
But to make the miner start up he needs the "starting help" otherwise there is only the red LED of death
Any suggestions?
