DC2/DM115: VSBbus 32-bit I/O and controller
This module, made by Access Dynamics
in cooperation with the
Fermilab DART divison, is a "smart" interface receiver for the 32-bit
fast data stream from the Fastbus electronics in the outer huts. It
controls two Dual Port Memory (DPM) modules in
"ping-pong" mode via a VSBbus link on the user ports of the VME
backplane, where it writes all receiving data to one DPM module and giving
the other one free for readout from the VMEbus.
