Rack-Mount Options
The VXI-1200 is available with a wide variety of rack-mount options.
The adjustable rack-mount ear provides variable extension
rack-mounting capability.
You can order rack-mount kits using either slides or rails. The kits
include documentation to guide you through the installation.
Backplane
The VXI-1200 backplane can accommodate up to six C-size VXI
modules and up to three B-size VXI or VME modules. The plug-in
Personality module allows either the C0 slot or B0 slot to function as
the mainframe VXIbus Slot 0 location.
The VXI-1200 has a jumperless auto-configurable backplane using
active-automatic daisy chaining for the VME interrupt acknowledge
and bus grant daisy-chain signal lines. This eliminates the need to
manually configure the backplane.
Distribution of the CLK10 reference clock is full differential providing
a low skew timing source.
Power is supplied to the backplane through a direct connection to the
VXI-1200 power supply eliminating wiring and sub-backplane
interconnect boards. The result is increased reliability and improved
dynamic current performance.
