What does IMAQ start?

Hi all

What does IMAQ start? On my eval of camera position, it fails in certain circumstances, and I am trying to isolate the cause.

Reminder: There is a rating system provided to me by MAY. When I use it as they delivered, it works fine. But of course, I need to perform very differently than the design of the MAY, and that's where the trouble starts.

The system is a Lenovo ThinkCentre running Windows 7 Pro SP 1 64-bit.

NOR-1433 PCIe framegrabber, two Camera Link cables running to the eval Board.

LabVIEW 2010 32-bit version,

NOR-MAX version 5.5.0f0,

NOR-IMAQ version 4.7.3,

Camera files 3.0.1 generator

The eval system was originally designed as a step 4, CL Medium. To illustrate a concept we develop, I want to run 8-tap CL full (really, I want 10 bits 8 tap but that's another debate). I used CFG to change the original file of the ICD and saved as a new file. When I use NEITHER-Max to move to this new camera file, the program fails when IMAQ Start is called, error -1074397153 is returned. «NOR-IMAQ: impossible to detect a recognizable video source'.»»  I'll join the two files from the CIM.

I see two possible culprits:

(1) IMAQ start is reading of registers on the camera and find something inconsistent with the settings in the file of CIM

(2) items in the bad file CIM contradict

Since it is a Sunday, I don't expect to get an answer very quickly, so I'll keep looking for my own solution for awhile. If I solve myself (excessively positive attitude), I'll post the solution.

Thank you!

Exactly, cheese.  And what was the real problem?

Ding ding ding ding ding!

No clock Z (or data, by the way).  It seems that someone (blush) I forgot to UN-comment the lines in the file of constraint FPGA affecting the pins on Canal Z.

The moral of the story: don't even bother of the Forum until what you watch on the "scope of application.

See you soon!

Another moral: framegrabbers are looking for a clock until they try to acquire.
