I have a customer that purchased the EVAL-AD7327 eval board along with one of the EVAL-SDP-CB1Z daughter boards which allow the evaluation board itself to be controlled via the USB port of a PC using the AD7327/AD7328 evaluation software found here: http://www.analog.com/en/evaluation/EVAL-AD7327/eb.html#DOCUMENTATION
Under Windows 7 on their PC, below is a brief description of their setup process/issue.
First off, their goal is to measure a 10KHz Sine Wave at 1V P-P @ 50Hz Source
The software is loaded on their PC and appears to initialize with no apparent issues.
They have verified the Jumper settings on their AD7327 Eval board with the User's Guide and no changes were required.
They soldered an external signal input to the A0 and A1 inputs (using input buffers).
They insert the EVAL-SDP-CB1Z USB-based daughter board into the system.
They start the EVAL-AD7327 software Application while everything is connected via a USB cable to their Windows 7 based PC.
They hit rescan to identify the EVAL-AD7327 board and the application identifies an accepted board; the Vin radio buttons on right side now work properly.
They select the Vin0 radio button on the side:
-Control Register bits 2-5 = 1
-Sequence Register bits 13 and 12 = 1
-Range Register bits 13 and 11 = 1
Note here that the control resister bits 10 to 12 are set to read only Vin1 as the application appears to accept each register load.
PROBLEM: When they press either Sample or Continuous, the system just seems to spin/continue, but then times out.
Any idea what they could be doing wrong?
Thanks in advance for your help.
