^^ Happen to know where one can find a tutorial on how to set-up a BE Controller to run with a Prisma?
From page one, CrazyGuys post:
BE controller information
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.
