Having trouble with Lecroy 2373 Memory Lookup Unit

[kazem]

I am writing a LabView 5.1.1 program for the Lecroy 2373 Memory Lookup unit. I am using the KS3988 CAMAC controller and the KS3988 VIs that go along with it.

I can load and then read the CCR of the MLU successfully.

I can NOT, however, load or read from the CAR, I think. And I can not load or read words to the addres specified by the CAR.

I am reading the manual for this device.

Is there anyone out there who has experience with this device?

Note: I had to change the original read VI of the KS3988 VIs since they do not work otherwise.

Thanks.

I just figured out the problem.

Not all CAMAC crates have the +/- 12 V pin assignment. The status byte, among other things, uses an auxilary -6 V which is supplied by the -12 V pin. The -6 V can be found at pin Y1, or the fourth pin up on the left side of the GPIB slots.

The crate that I have does NOT have 12 V pins. Therefore, the status byte, and things like the Lecroy 2373 Memory Lookup unit DO NOT work.

Being the hack that I am, I wired -6 V of power into my crate, and now everything works. It looks a little dangerous, but it works.
