K1297. For the K1297 the usage of an AP-4 or AP-4/256 board depends on
the number of interface boards.
K1297 Compact. For the K1297 Compact the AP-4 or AP-4/256 board is
optional.
For configurations with 1 or 2 interface boards an AP-4 or AP-4/256 board
will only be needed for heavy demanding applications. Using an AP-4 or
AP-4/256 board speeds up decoding approximately by factor 10. The disk
throughput performance raises by at least factor 2.
For configurations using 3 and 4 interface boards we recomment using an
appropriate processor also for lighter loads.
For configurations with 5 and 6 interfaces the AP-4 or AP-4/256 board is
mandatory.
NOTE. Keep in mind that using an additional application processor in the
K1297/K1297 Compact housing needs an additional VME bus slot.
CAUTION. Before installing a new board ensure that the VME bus address
is set correctly (cf. chapter Getting Started, section Exchanging Measuring
Modules).
Defining new CPU numbers must be performed at an ESD approved
workplace. Electrostatic discharge can permanently destroy components
that have to be temporarily removed from your device.
