Configuration Settings

This appendix describes the alternate hardware configuration settings for
the VXI-MXI-Express Series controller. The board is set at the factory
forthe most commonly used configuration. Use this appendix if you
wantto try a different hardware configuration or if you would like more
information on a particular setting. This information is intended for more
advanced users.
The following hardware configuration settings are user configurable.
• Slot 0 detection
• VXIbus CLK10 routing
• SMB Trigger I/O
• Backplane trigger I/O
For the configuration switch locations and default settings, see Figure B-1,
VXI-MXI-Express Shipping Configuration Settings.
Note Do not attempt an alternate setting unless you are familiar with its purpose.
Inaddition, do not reconfigure any switches or jumpers not described in this appendix
unless directed by National Instruments support.

Slot 0 Detection

The VXI-MXI-Express Series controller is configured at the factory to
automatically detect if it is installed in Slot 0 of a VXI mainframe. With
automatic System Controller slot detection the VXI-MXI-Express Series
controller can be installed in any VXIbus slot.
The VXI-MXI-Express Series controller can be manually configured for
either System Controller or Non-System Controller operation by defeating
the automatic detection circuitry. Use the three position jumper J2 as shown
in Figure C-1 to select between automatic detection, System Controller, or
Non-System Controller.
