If you are asking about the R4, it is much quieter that the s4. About the same as a s3 running full speed, my furnace blower is louder than the R4 I have in the TV room.

hmm, very new I guess but we were all there at one time.. They are talking about the transaction ID code or TxId. In your Bitcoin wallet check the status of the tx. That is where you will find the Tx Id.

After you do a BTC transaction a code is issued that identifies it in the Blockchain forever.  eg a2c8d0f9e9d6185cf5dd0383812e123d3e8f330b87b012de5eb58edacb08245f

That breaks out into https://blockchain.info/tx/a2c8d0f9e9d6185cf5dd0383812e123d3e8f330b87b012de5eb58edacb08245f for a s9 I bought.

 Also - you MUST tell Canaan that that you are using BTC. Reply to the email they sent with wire transfer info and tell them that you will be using BTC. They will reply with the BTC amount and address to send it to.

Lastly - this is the wrong thread/section for a question like this...

First, NEVER update firmware unless something is not working to begin with.

2nd, yes other folks have had issues as pointed out many many times in the main s9 thread https://bitcointalk.org/index.php?topic=1493601.0

The fix is start a support ticket and send in to be repaired.

I MORE than agree!!!
Long ago I tried using a couple "2KVA' like that. http://www.world-import.com/tc-2000a.htm#sthash.L9AWFcYN.dpbs

Running 1,500w 24x7 literally fried the inside of both in less than 2 month. As in upon opening the case finding charred remains of wire and windings....

Get a real industrial/commercial grade xmfr that you will have to wire yourself. Eff is much higher, around 95-98% is common due to much better construction and they are bullet proof.
eg https://www.mcmaster.com/#6980K8
Not pre-wired with cord and outlet is far cheaper but still $$ https://www.mcmaster.com/#transformers/=16lpx2e

or just type in Bitmain.com

Not so much a pretty graph, but one that displays large variations better. Say a log-scale display option with 2 or 3 steps. I agree it is good to know/see how the Avalons are really reporting.

Why as many as 3 steps eg. 0-10, 10-100, 100-1000THs? 1 Avalon RasPi controller can run up to 20 miners. With Avalon 741's that is 150THs sustained average reported as 1 miner. God knows what the reported peaks would be....

That way AW's auto scaling doesn't result in the lower hash rate miners (s7's & 12-14THs s9's!) being swamped out. Speaking of which, today I added a741 to the chain of 3x 721's. Sustained hashrate reported by Kano is >28THs, on par with Canaan's GUI reports. However um, spikes over 100THs happen several times an hour so the s7's, R4, and yes even s9's are down in the mud...

A new bit about the Avalons/Controller: When miners are connected in a string off of 1 USB/I2C adapter, Canaan's GUI gives info about each miner in the string. AW reports them as 1 monster ASIC.

However, if I use 2 of the USB/I2C adapters and still just the 1 controller, then Awesome reports the new adapter/miners chain as a 2nd ASIC in the miner (controller). Of course as desired Awesome does still report just one miner and total specs on its output.

Point is, if I want to see how each individual miner is running then I can only run 4 physical miners per 4-port RasPi. Rather defeats the point of being able to chain 5 physical miners from each of the 4 USB ports giving 20 miners per controller.

The heaters in the dryer are wired across the 2 hot lines to be fed 220v. They would not use the Neutral/ground connection for power. Only through that center pin (which is becomes more of a Neutral, not so much a Ground anymore) to either one of the hot pins will you get 110v.

Now if you say take one of those 2-to-3 prong plug adapters that will give you a connection to the 120v power strip ground wire, plug that into the adapter you are looking at, plug the power strip into the 2-3 prong adapter and make sure  to WIRE THE GROUND TO A REAL GROUND, then ja is a kludge but is heckovalot safer...

Best route: Most PSU's are quite happy with and in fact prefer being fed 208-240VAC. Check the label on the PSU of course If it is dual voltage make sure there is no little red voltage selector switch by the AC power socket you will need to toggle. Most supply handle that automatically.So, that said...

Check Amazon, E-bay, etc. for a 220v 30A 4-outlet PDU (pretty much is a 220v power strip).

Check what kind of outlets it has: Most likely they are standard IEC-13 (aka C13) so while there get some cords for the PSU's, one end male C13 the other end the normal female C13.

The plug end of the PDU cord will probably not be right so go to Home Depot or local hardware and get the right 220v 3-prong plug to fit your socket. Cut existing plug off of PDU cord and rewire with the new plug.

Done.

Um, yes....
What it most likely does is connect to 1 of the hot lines and the center pin which for appliances using that style of 220v plug is a power Neutral along with being a (sorta) Ground tied to the metal appliance cabinet. That gives you the 110VAC.

Yes it meets Code. Sorta.
Appliance makers used to be allowed to do that so there is 110VAC available in the appliance for things like timers and light bulbs.

2 Problems with that: 1st is that you have no true safety ground.
Yes Neutral and Ground are tied together at the main panel but -- once you start pulling power through the Neutral the plug end of it WILL be a few volts above ground. Just the nature of the setup. Under the original intent (timers/light bulbs) the power through the Neutral was negligible so the voltage difference was not of major concern. However, these days most areas require a 4-wire connection - 2 hot, 1 Neutral for 110v needs, and 1 real Ground as a 'Just-in-Case'.

2nd issue is that the breaker feeding the 220v plug is now under unbalanced load because only 1 hot line is drawing power through the 1 side of it vs both sides being under load. Yes it should/will work if needed but it simply was not designed to operate like that.

For a start, are you using Canaan's controller software on a Raspi?
If so can you use your browser to open the controller GUI? What does it say?

^^ Yep
I used to have the lyrics to the flip side somewhere - is done backwards...

Thanks, got the site bookmarked just in case. Just checked and STILL not confirmed even once.
I already let Bitmain know about it and gave them the txid. They responded and will keep the order alive until confirmed.

Hmm, that reminds me... Gotta tally up how many s7's I have. Think it's a couple dozen.

A while ago I talked with another member here who is in the MM business, said that he has a (I assume legal) grow-op in my area with 3-cent power and brought up maybe hosting there... Might say give him half the s7's in return for 6mo-1year of 'free' hosting the other 1/2. Only problem with that is the PSU's from the s7's now power s9's. Damn.

Could be fun
Getting Avalon's (2x 741's arriving Fri) is rather like vaping vs having a cigarette: Works but not the same rush.

Swapping out 2 low(ish) power s7's, plugging in a s9 to fill the power freed then getting over 2x more speed while pulling a bit less power vs what the s7's did together... Priceless.

Now the problem is how to deal with unsightly off-line s7 buildup...
I have -- a LOT of them...   At least with my s1's, 3's, a s4, and all of my s5's I was able to put them on a pallet and send them to Sidehack as a parts donation

That was my feeling. No coupon (I skipped the last 2 rounds of s9's) but price was much better and with BTC being sky high right now, decided to roll dem bones on another to satisfy my Jones'ing for a while..

tx is still unconfirmed btw https://blockchain.info/tx/a2c8d0f9e9d6185cf5dd0383812e123d3e8f330b87b012de5eb58edacb08245f

Continuing thoughts into what Avalon's display https://bitcointalk.org/index.php?topic=676942.msg17968629#msg17968629 and followup https://bitcointalk.org/index.php?topic=676942.msg18027671#msg18027671 as massively spikey 5-sec hash rates, wonder it is from how/when the 1 controller is talking to the 3x 721's chained off of the 1 USB/I2C adapter coupled with how Canaan's (legal) fork of CGminer reads that? Looking at what Canaan's GUI displays they must be smoothing out a lot of samples...

Perhaps for several sec or more there is nothing to report to AM followed by a massive data burst as the miners in unison report findings/request more work? I can easily see that the light on the adapter only flashes with a burst of activity for a couple sec maybe 5x a minute.

Ouch!!!
I've been luckier than that. So far 10x s9's starting from batch-1 (still the fastest) on up. Total of 2x hash boards died long out of warranty. Had repaired in CO.

R4's... 1x Batch-4 runs great as does one of the batch-6. Both flawless so far. The 2nd b6 that arrived just 4 days after the first - 1 hashboard died just after 24hrs. Will eventually sent to CO for paid repair but for now is running @ 4.6THs on the 1 good board.

That said, ordered a new s9 a couple hours ago. After the latest round from Bitmain, fingers crossed on how it runs...  Now just have to wait for the tx to be confirmed... Sent from wallet 5hrs ago and still unconfirmed! yeesh...

I probably will get 1 more s9 eventually but I only have a few more under-clocked/volted s7's left to take off line at work. I *do* have a power budget to stay at so eventually it will be just s9's and assuming my 2 new ones arrive tomorrow, 5x Avalons: 3x 721's and 2x741's

For me, especially with any auto-tune Ant -- only when needed because sustained hash rate dropped substantially. If using miner software like Awesome Miner try restarting just CGminer - not the Bitmain GUI soft-reboot of the whole controller. Should skip the normal initialization needed.

For my s7's and older s9's is good to reboot every month or so. I've noticed that all of my ants from at least s5's get - odd - after 30-50 days. Seem to run fine but things like HW errors gets stuck, maybe hash rates drops several %. Reboot and all is well again.
