National Instruments 800 Series 用户手册

The following material applies equally to all models in the VXIpc 800 
Series. 

You need the following pieces to install an expansion board in the 
VXIpc-800:

•

A user-defined panel is required on the expansion boards based 
on National Instruments blank PCI or ISA panels. The panel 
should be manufactured from 0.03 in. (0.76 mm) thick 1010 cold 
rolled steel. The finish should be 0.0003 in. (0.008 mm) nickel 
plate over 0.0001 in. (0.003 mm) copper flash. Contact National 
Instruments if you have any questions about specifications for 
user-defined panels.

As an alternative, you can modify the blank panels provided with 
the VXIpc-800. Custom panel design services are available from 
National Instruments for a nominal fee.

•

PEM nut or a 4-40 nut with lock washer (hole diameter should 
be 0.125 in. [3.18 mm]).

•

4-40 x 1/4 in. stainless steel panhead screw.

Follow these steps to install the expansion board.

1.

Notice that the VXIpc-800 includes one card guide that can be 
rotated to secure the top of either a PCI or an ISA plug-in board. 
You may use the card guide in either of two locations, depending 
on the length of your installed board. Notice the possible locations 
as shown previously (Figures E-2 and E-3 for the VXIpc-850, or 
Figures E-5 and E-6 for the VXIpc-860). Loosen the screw holding 
the guide and rotate the guide to the uppermost position for PCI 
boards or the lowermost position for ISA boards. See Figure E-7.

2.

Replace the manufacturer-supplied panel bracket with the custom 
bracket. The two holes in the bracket align with existing holes in 
the VXIpc-800 front panel. 

3.

Seat the board firmly in one of the expansion bus connectors.

4.

Attach the board to the front panel with the two screws. You can 
use a PEM nut on the back (far) side of the bracket, or a 4-40 nut
