Title: Prisma/Tube Cp2102 MOD Working Post by: person6278 on November 20, 2014, 12:34:43 AM BIG Thanks to novak@gekkoscience for pointing me in this direction.
I have my old Asic Tube working using a modified CP2102.. Here is what I did to help yall out. I Did this using Odruid U3 from hardkernal lets call it a beefier RPI. I have it running Ubuntu. First off a special version of cgminer is needed.. sudo apt-get install build-essential autoconf automake libtool pkg-config libcurl3-dev libudev-dev git clone https://github.com/blockerupter/cgminer.git ./autogen.sh CFLAGS="-O2 -Wall -march=native" –enable-blockerupter make ./cgminer --bet-clk 27 You should be up and hashing after this. Of course the usual put in your pool and user info.... I will post pics of my sloppy setup. This is the USB UART I used http://www.amazon.com/gp/product/B009T2ZR6W/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 KEDSUM® CP2102 Module STC Download Cable USB 2.0 to TTL 6PIN Serial Converter For STC https://i.imgur.com/WEyJgrDl.jpg And https://i.imgur.com/SeECzfSl.jpg Look at the hashrate averages.. The instant hashrate jumps around ALOT https://i.imgur.com/sP9N27al.jpg And hey if this helps anyone A tip would be awsome Bitcoin address to send to 16nP1WnxRdvbE64fqzyebx1eZnWdxdiPxp Title: Re: Prisma/Tube Cp2102 MOD Working Post by: novak@gekkoscience on November 20, 2014, 12:46:15 AM Did you have to add a resistor? Either way, post some pics of the adapter.

And I'm trying to figure out how to post pics now.. LOL Title: Re: Prisma/Tube Cp2102 MOD Working Post by: novak@gekkoscience on November 20, 2014, 01:07:36 AM Yes resistor has to be there or its a no go.. And I'm trying to figure out how to post pics now.. LOL You have to post links to images with the img tag. So put them on photobucket or whatever and post links. -- novak Title: Re: Prisma/Tube Cp2102 MOD Working Post by: person6278 on November 20, 2014, 01:36:35 AM This is my current power usage It includes the odriod u3 cooling fans and Asicminer Tube.
https://i.imgur.com/EVRmL70l.jpg And My Tube looks like this.. https://i.imgur.com/duiC7Wzl.jpg and https://i.imgur.com/LspZUkXl.jpg And these bad boys are how I power it all https://i.imgur.com/9lj6EjSl.jpg Mods to make them work. Yes those wires go out to 4 pci express each. So 2 boards per psu. https://i.imgur.com/aG9GkEAl.jpg They can be purchased for about $25 US off ebay Part Number 438202-002 Product Type Power Supply Generation DL580 G5/ BLc3000/ DL785 G5 Wattage 900W-1200W Input Voltage 120-240 V AC Hot Pluggable Yes Redundant Yes Auto Switching Yes Cooling Active Fan FAN Internal Other Part Number 437572-B21/ 438202-001/ 438202-002/ 440785-001/ 441830-001/ 438203-001/ HSTNSDL11 And a good pic of the tag.. https://i.imgur.com/I4w4WFYl.jpg And these for the PCI Express connectors 6-Pin Power Adapter Cable for PCI-Express - 10 inches http://www.monoprice.com/Product?c_id=102&cp_id=10245&cs_id=1024503&p_id=2883&seq=1&format=2 You may find cheaper but I thought I found some good deals.

And using ./cgminer --bet-clk 30 to start cgminer https://i.imgur.com/bcTlCzrl.jpg Check your power supply feed Right at the pci express connector at the hashing boards see what voltage you get. Mine were around 11.8* and was having one world of a time getting past 820 Ghs or so.. now 1.* Ths. I opened my PSUs and adjusted them till I had 12.05 at the connecter UNDER LOAD and now im hashing perfectly at a good over clock. New power draw running at 300 and getting around 1 Ths https://i.imgur.com/q7iIDIHl.jpg And for those wondering this is what the cable ends look like on each PSU https://i.imgur.com/Y4ZtAfHl.jpg Remember Set your voltage UNDER LOAD. I am not responsible for damage done to ANYTHING. Always find out what pot needs to be turned which way it needs to be turned and GO SLOW.

Title: Re: Prisma/Tube Cp2102 MOD Working Post by: person6278 on November 20, 2014, 01:23:50 PM I based this off the fact the maker of Asicminer Tubes/Prisma references the fact that the controller whether it is there premade usb-uart or a be-200 controller will control Tubes/Prismas daisy chained together, and that they can be chained together. If I have made a mistake and my educated assumption is wrong I will be more then happy to delete/modify this thread. Any one that owns a prisma feel free to chime in and let people know 100% one way or the other. I only own a tube I cannot afford a prisma.
Title: Re: Prisma/Tube Cp2102 MOD Working Post by: person6278 on November 20, 2014, 01:52:55 PM And better pictures of the usb-uart
https://i.imgur.com/qTXWKW2l.jpg The other end of the resistor is tied into the RXD line https://i.imgur.com/oEs9SRal.jpg https://i.imgur.com/9UFjBHwl.jpg And my sloppy way of connecting the uart to the tube...Yes I know looks bad. Will be picking up the parts I need to make an adapter after work. https://i.imgur.com/cdJNOiHl.jpg https://i.imgur.com/9Fge5dJl.jpg Title: Re: Prisma/Tube Cp2102 MOD Working Post by: tutorialevideo on November 20, 2014, 02:17:41 PM great! make a video if you can to see al the steps
Title: Re: Prisma/Tube Cp2102 MOD Working Post by: sidehack on November 20, 2014, 03:44:15 PM I'm pretty sure novak tested his USB-BE hack on a Prisma as well. Tubes and Prismas are pretty interchangeable as far as controllers go.

Tubes and Prismas are pretty interchangeable as far as controllers go. Yep. Also ManeBjorn tested one on the Rockminer T1, which is for all practical purposes a tube, and it works with that too. -- novak Title: Re: Prisma/Tube Cp2102 MOD Working Post by: ManeBjorn on November 22, 2014, 07:56:48 AM Yes it runs on the Rockminer T1 as well.
I am using Crazy Guys RPi Minera image for it and he has a RM cgminer for it as well. Works great I love the better control with the RPi and pool failover and MultiMiner support with Minera.

This shows you what color goes to what wire.. and they are connected strait across on the PCB. https://i.imgur.com/tpVnh8Jl.jpg Just a quick side view https://i.imgur.com/S2XQvCal.jpg And a decent shot of the usb-uart and which color of wire goes to which spot. DO NOT FORGET the 1 k ohm resistor from the 3.3v feed to the brown wire AKA RXD https://i.imgur.com/XoSP0Mgl.jpg I took my clock back down to --bet-clk 27 Full size link https://i.imgur.com/z570R82.png https://i.imgur.com/z570R82l.png And No I am sorry I have ZERO interest in doing a video on how this is made.. Mostly because I do not have another usb-uart to solder together, and I have no need to order another one unless some one wants me to modify one for them I can think of a couple ways to make it look so much prettier. You could clip the leads on the resistor and solder it directly from 3.3v to the RXD spot on the PCB. Use a PCB board that plugs directly into the usb-uart to the Tube/Prisma uart cable.
