Topic: [CLOSED] ASICMiner Prisma 1.4th/s - 1.47 BTC - page 28. (Read 49702 times)

No, it comes with six 6+2 PCIe adapters.

Do those EVGA PSU come with 8 pcie connectors? I would recommend using all 8 connectors to lower the load on each cable. If you are only using 4 of the connectors, make sure the cables and connection points aren't getting hot. You are drawing about 250 watts through each cable with 4, so make sure they are high quality 16 guage and bump up to 8 if possible, or risk melting the cables or connectors.

Thanks, I ordered the adapter in doggies guide, which I think is the same one you have, or at least compatible. I also plan to use btcguild stratum servers.
 

That's good to know. I'll post when I have it...

Just got a Prisma in. The USB adapter uses the favorite CP2102, and we checked the firmware; it spoofs the ninth data bit by switching parity modes to force a "1" or "0" as needed in an 8+1 parity mode. So an off-the-shelf adapter would probably work, if you know what pins are what signals on the machine and the signal voltage is right.

Couple things I forgot to mention, looks like the Ape figured it out on his own.

1) The prisma and Tube BE controller are the same, but tube controllers are setup by default at a frequency of 270. If you receive a tube controller, drop the frequency down to 240 before connecting a prisma.
2) BE controller's default address is 192.168.0.254. The easiest way to access it the first time is by connecting to your PC or laptop via crossover cable or put it on a network with the same subnet.
3) BE controllers require a power source of their own. They can reliably handle anywhere from 5v-12v. I have tested with both a 5v 2a and 12v 1a power adapter. The power adapter will need to have a 2.5mm barrel connector.
4)  The BE controller supports ghash.io and slush by default. BTC GUILD and ckpool are also supported, but they use different addresses for tubes and prismas. See dogie's tube guide for more info on supported pools.

It's my Jalpeno power brick Model: PC-C-090-130060CT  

EDIT: Does anyone think adding a second fan will slow the one fan down hence making it a little quieter?


I've got it pointed at stratum-lb-usa48.btcguild.com   port# 3333.

Can you tell me the model number of the power brick you used? LOOKS GREAT!

I got my first 2 from batch 1. I just have 1 up and running my additional psu's should be here later today. EVGA 1300 G2 the cables are a little warm but it seems to powering it.
The BE Controller didn't come with a power brick (not CrazyGuy's fault).
It is fairly loud. So the fan doesn't adjust? It just going at the same speed (high) constantly.

One other thing I realize I may need is the power adapter for the Controller. Does the controller come with a power supply? I guess I could tap off the power supply.

If that's true then no it probably won't work. It will be here tomorrow. I'll post results but doesn't look promising if what you're saying is correct.

I was told all I needed was the controller and the tube by someone else selling tubes. I hope to just plug it in and bring up the web page. Is that possible without changing the switches? In other words, what is the default IP set to? 192.168.0.X I guess? Were they pre-tested at the factory? I am thinking not...

If these are controlled the same as the Tubes - which seems likely since they run on Tube controllers as well - you would need a USB-UART adapter's RX, TX and GND lines. I think it's a 3V3 signal voltage. But the actual protocol was a nine-data-bits, I think no parity, at 460800 baud, which isn't a mode that many converters support. I'd be surprised if the one he bought would do it, based on what Novak turned up while working on RPi support before AM released their cgminer stuff.

I am batch 1, and will use an EVGA 1300. I will let you know if it works when I get it up and running. I also have a killa-watt meter and temp gun. I bought the extra controller, so we will see if I can figure out how to set it up since I've never had a tube setup before.

Thanks GrapeApe. I just want to be sure I have everything ready when they show up. Now about them running on a B+ PI is my only concern. And of course power. Thanks again

NO don't buy one. I'm just trying it out to see if it works. They are supposed to come with an adapter but batch 1 didn't have them. We don't know if this was intentional (maybe there is some kind of issue) or if it was just oversight.
Just wait...

I ordered two on batch 4. Do I need to order those uart to usb adapters that GrapeApe bought? I know starting at batch 4 they came with something I am guessing it was these adapters wasn't it? Im also curious how these are going to work on a RPI, I have the B+ model and now im getting nervous as shipping is getting closer. Time to get the latest minera image on that B+ and give it a shot. They do look nice, cant wait to get my hands on them. Thanks CrazyGuy

if anyone would like to sell one of these from batch #1 or #2 , please PM me

I now have tracking for batch 2.

I've added final shipping dimensions and weight to the second post. Also, after a bit of head scratching, I've figured out that AM reversed the order of the 5 bit switch in comparison to the Tube. Adding to that the limitation of a 4 bit configurable address space.

Here's what you need to know:

1) Each physical board has two addresses in a 5 bit address space. Only 4 of those bits are configurable. Boards 01-16 are paired with logical boards 17-32, starting with the first switch configuration(0000). This results in the first physical board having an address of 01 and 17
2) Boards must be chained in incremental order. (Example: 01:17,02:18,03:19,04:20,05:21...)
3) The least significant bit is reversed from the tube, with the tube's last switch,"5", being the least significant bit and the Prisma's first switch ,"1", being the least significant bit. Off and on still refer to 0 and 1 respectively.

Warning: Leave Switch 5 alone! If you set it on for any board, the controller will not see any boards in your chain.

Can you confirm all 4 from batch 1 + 1 be controller shipped? I only see movement on two out of four of the tracking numbers/labels I sent.

[edit] I see movement now on all 4. USPS is slow to populate all the numbers can you tell I'm getting antsy?
