This is a listing of VXI Equipment Enclosures and Chassis
manufacturers. The types of products or equipment they produce are listed
under the company name, in alphabetic order. There are a number of terms,
which all mean the same thing, used to describe an electronic enclosure
which hold circuit cards: Case, Chassis, Crate, Mainframe, and Enclosure.
The enclosures may also be sub-divided into Rack-Mount, Wall-mount,
Tower, or table-top; Commercial, Industrial, Rugged, or Military. A
Sub-rack is not a complete electronic enclosure and may only include a
metal frame and a card cage. A Card Cage has no enclosure at all and is
just a frame [with card guides] to support the particular CCA form factor
used.
If the Chassis is produced for a particular card form factor, for example
cPCI, then you can also check that
particular BUS page for more data or the
COTS card vendors page for a listing of
CCA manufacturers.
Refer to VXI Bus Description for VXI Design Info and additional VXI details.
A VXI [(VME eXtensions for Instrumentation] Chassis will be
between 1 and 13 slots (the maximum)
VXI Chassis Terminology:
"A-size" mainframe: Provides J1 only {mandatory}, allows for the
insertion of an A-size module only.
"B-size" mainframe: Provides J1 {mandatory}, J2 {optional}, allows for
the insertion of a B-size module.
"C-size" mainframe: Provides J1 {mandatory}, J2 {optional}, allows for
the insertion of a C-size module.
"D-size" mainframe: Provides J1 {mandatory}, J2 and J3{optional}, allows
for the insertion of a D-size module.
Additional VXI Chassis Requirements:
Card guides shall be made of non-conductive material, or be isolated from
chassis ground.
Each backplane shall be a single monolithic board, within any slot
position.
All mainframes shall provide chassis ground to the module front panels in
the area of the front panel mounting screws.
Any voltage furnished by the mainframe power supply shall comply with the
maximum Allowed Variation and maximum allowed DC Load Ripple/Noise.
The [VXIbus] chassis may except 3U cards, or 3U and 6U cards, or 9U
cards. The chassis may have a separate card cage to handle the 3U cards
or 6U. The chassis only need provide the P1 side of the back plane when
only 3U cards are used. 6U cards require both P1 and P2, and 9U would
require the P1, P2, and P3. A P0 connector (between P1 and P2) for 6U
cards may also be provided. Regardless of the size of the card the
chassis will accept (3U, 6U, or 9U) all the slots are on .8" centers. The
chassis may be a table-top or rack-mount.
VME32 provided a +5volt,and +/-12volt supply; VME64 added a 3.3 volt
supply. The 5volt supply should provide only 50mV of ripple. No currently
produced power supply meets 50mV, I've seen notes on the web indicating
an attempt to update this number.
