Re: Electronics at IU
Hi Matt,
I talked to David Abbott about the cPCI crate you have. He recalls
ordering both a VME64x and cPCI crates from Tracewell but he does not
recall shipping it to IU. Is this crate a Tracewell crate? This are used
for prototyping and provide access to the electronics from the side and
has a limited number of slots.
If this is a Tracewell crate, there are several options;
1. You can contact Tracewell and have them "update" it to VME64x by
replacing the backplane. You don't need a VXS to use the fADC250.
2. You can buy the backplane from Tracewell and have it installed at IU.
3. Send me the crate and we will update per 1 or 2 above.
The update should cost in the neighborhood of $2k but at least we
recover some of the cost from purchasing it as cPCI crate. These are my
suggestions and I don't know if Elke has the money under option 3. I
will talk to Elke sometime today.
Best regards,
Fernando
