Correct link placement for standard AD7732 Eval board use

Hello all,

 

I am using the EVAL-AD7732/34EBZ board and am having trouble getting it to connect to my computer.

 

What I've done: Powered the board to +/-15V, powered AVdd and DVdd to +5v, powered AGND and DGND to ground. I then connected an arbitrary waveform generator to the T0(the positive analog input) and T3(the negative analog input). Then, I plugged it into the computer and followed the instructions in the Easy Start program. When attempting to "Reset the Board", I get the error "Board can't be accessed".

 

So, I followed the instructions to download the hex file to the board. I removed LK28 and followed the instructions and supposedly it was succesful. Then, I tried following the instructions on the Easy Start program again. Still, I got the errors "Board can't be accessed".

 

The arbitrary waveform generator is giving out a sin wave 1Vpp and 1Hz.

 

Am I doing something wrong with the LK placements? Other than removing LK28, I haven't touched any of the links. Everything is on the board the way it was shipped from manufacturer. Any hints on getting this thing to communicate with the computer?
