Experimental Physics and
Industrial Control System

Hi,

Ever since the KEKB accelerators became operational, the VME/MXI/VXI
connection has been a  problem. Recently Mr. Akiyama of our group
studied the problem carefully and identified the source of problem.
After the discussion with National Instrument, the maker of VME-MXI
interface board, we applied a modification to the VME-MXI board
following the suggestion by NI. 

Since the modification, we did not observe this problem in the KEKB
system. 

You can find more information at

Bye.
