-edited for clarity-
Everything you need is right here in this post...no guesswork involved just RTFM

I circled the 3 pins where you connect to in red here:

Looking at the controller board straight on, the ground *should* be the pinhole on the far right, if not its far left (double check with voltmeter as I have no unit to test right now) the other 2 pinholes are tx/rx.
Once you confirm the ground (0v on voltmeter), then connect tx and rx....if you get a load of junk on your screen reverse the rx/tx and you will see magic...well not really but you will see the data on the screen...for putty set 115200, no flow control, and make sure you have the correct COM port defined (115200,8,n,1)
I posted a direct link where to get the cp2102 earlier (the tx thing)

http://www.dx.com/p/usb-to-uart-5-pin-cp2102-module-serial-converter-81872#.VI6YldJ0yUlThere is no bs ad commission or anything for that part; you can order it anywhere on the net..I provided the link where I got mine to make things easy (or so I thought)
In Short...you need the thing in the picture (link provided) putty for serial connection and 3 bogo pins (that's what the gold pins are called)
Alternately you can just use sewing pins and push the sharp end into the connector MacGyver style, just don't move anything once you have them connected

Once you have access to the miner, type
mtd -r erase rootfs_data and hit enter
then type
REBOOT and hit enter...then wait 3 minutes before accessing the default miner IP address...
do not power cycle the unit Last of all...don't hold me responsible if anything goes wrong...but if I helped, a thanks would be great
