Title: How to setup a PRISMA using BE Controller ?
Post by: vortexz on November 11, 2014, 11:09:35 AM
Today I just got my PRISMAS but honestly I have NO IDEEA how to set them up.
Anyone here that already configured a PRISMA can help me ?
I need step by step starting with the wiring coming from the BE controller.
How many PCI-E wires I have to connect coming from the PSU ?
Thank you very much !

There.are 8 sockets, 2 on each board. You will need a power supply in order for the Prisma to hash.

power the boards
make sure each dip switch is set to a different id number (more info in dogie's asicminer tube info setup thread)
wire the 4 blades together using the 3pin wires
plug a 3pin wire into the uart1 spot on your BE controller.
in the be controller - 192.168.0.254:8000 by default - set the ip, etc of the controller.  Se the clock speed to closer to 240 or 230 for more apt to be stock perforamance.

If you use all 8 PCI-e plugs great, that's the best setup.  IF you only use 4 of them (1 per board) make sure the wires are 16ga and can supply at least 250w per plug, ideally 300w. or more.  Which is why ideally you want to have both plugs populated.

After you have it up and running run

http://192168.0.254:8000/FlashMega to update the firmware of the chips and the BE controller.  Set a prisma up like this the other day in a few minutes.
