I have a worker on slush's pool, I have my BFGminer running (Pool 0 is hiding block contents unsure if that's important) and my Antminer S7, but I can't seem to get it to see it as a device. It ask for a target which is a serial port to probe for mining devices but I'm unsure what it's asking.
The Antminer S7 runs standalone. It has a micro-controler that runs CGminer, and a web interface where you can point it to any pool you want. You just need to figure out the IP address of the miner, then type it in a web browser. The default password is
root/root, if my memory serves me well.
In any case, you should read the manual.
