I remember buying a bunch of delta fans to add fans to our S7-LN machines and to get them to read we had to swap the two data wires so the s7 could read them
Ah ha! That explains the Delta datasheet I just looked at for their newest fans. Their wiring diagram showed yellow as the PWM command and blue as feedback which is the reverse of most fan wire colors....
Thought they may have screwed up the diag or I was going nuts...
The other possible 'gotcha' is that there are 2 styles of PWM control and of course they are also the reverse of each other: 1 uses zero or very low pulse duty-cycle = full speed and as duty-cycle increases the fan slows down. This is safest because if the command wire is cut or shorts the fan runs a full speed. The other control method is 100% duty-cycle = 100% speed. Anyone ever check to see which Bitmain uses?

hi All, my A741 is running at Temperature 45-50 / 98 - 100, with 100% fan speed and -1 Power. Anyone know what's the maximum allow for this machine?
What's your temperature ?

Re: Unofficial Avalon 721 thread setup review etc. photos
I like the second idea. I will note it and test it when my A7 come next week.
Thank you.
hi philipma1957, i have some confused, your A7 ip is 192.168.0.100 it's because your home router is set 192.168.0.1 right? so, if my home router is 192.168.1.1, the A7 ip might be something 192.168.1.100 correct?
192.168.0.100 <-- this is not the fixed ip for A7 ,
or maybe im wrong?

hi philipma1957,
Im just switch from S9 to A7, just ordered! as i know the default ip for A7 is 192.168.0.100, but, my router is 192.168.1.1, it's possible to change the Avalon controller ip from 192.168.0.100 to 192.168.1.xx ? possible?

i received the reply email from Bitmain to share with you all.

hi all, please help, after upgrade my s9 to latest version, i cant hashing anymore.
"Socket connect failed: Connection refused"
my version is 12.93ths, i have set the 600M freq, but still cant make any hashing.
please help...
first look at the mirror and curse at your self for doing a firmware upgrade when your gear was working.
next power down. wait 5 minutes power up
then wait 1 hour and check your gui
good luck bro
I feel very regret for doing upgrade!!, seriously.., it's an hour ++, it's still not hashing,.. Oh My God!, it's anyway to restore to its original version firmware?
