Example: Control of high voltage
N.B. Not every VME interface is supported by EPICS!
N.B. EPICS is based on a one-to-one relationship between
each database record and its hardware channel.
Multiplexing requires an extra layer of software
(read “driver”) which does not presently exist!
Be prepared to pay for every channel you ask for.
