Hello Avalon mining system users, I need a little help. On the Control Unit card, Version 1.5, there is a P2 header with 6 pins, near the JTAG1 and P3 headers. I know that the P3 header is for the thermal transistor that measures the temperature of one of the heat sinks. However, I don't know what the P2 header is for. Is there anything plugged onto this P2 header? Or are there jumpers? A picture of your Control Unit with the P2 header clearly showing would be a big help.
Thanks for your reply.
Temperature is measured on two of the heat sinks. Cgminer shows 3 temperatures, I guess the third one is on the control unit itself. Interesting is the numbering of the fans with number one being in the middle IIRC...
I am not near my miners, but P2 is either the LED's on the front of the housing, or if they are connected somewhere else, empty.
