/*
DESIGN LIMITATIONS...
1 - Like all controllers, the IM483 must be powered-on when EPICS is first
booted up.
2 - The IM483 cannot be power cycled while EPICS is up and running. The
consequences are permanent communication lose with the IM483 until
EPICS is rebooted.
3 - Like the Newport MM3000, the IM483's position can only be set to zero.
4 - The IM483 uses an internal look-up table for acceleration/deceleration.
Translation between the IM483 and the ACCL/BACC fields is not obvious.
