Chapter 1 Introduction

Optional Software

Your VXI-SB2020 kit includes the NI-VXI bus interface software for Solaris. In addition, you
can order the LabVIEW or LabWindows
programs match the modular virtual instrument capability of VXI and can reduce your VXIbus
software development time. LabVIEW is a complete programming environment that departs
from the sequential nature of traditional programming languages and features a graphical
programming environment. LabWindows/CVI is an interactive C development environment for
building test and measurement and instrument control systems. It includes interactive code­generation tools and a graphical editor for building custom user interfaces.

Both LabVIEW and LabWindows/CVI include all the tools needed for instrument control, data
acquisition, analysis, and presentation. When you order LabVIEW or LabWindows/CVI, you
also get more than 300 complete instrument drivers, which are modular, source-code programs
that handle the communication with your instrument so that you do not have to learn the
programming details. You can use both programs with either Solaris 1.x or Solaris 2.x.

If you want to use LabVIEW with your VXI-SB2020, you must order the LabVIEW for Sun
VXI Development System that corresponds to your Sun system. The following kits are
available:

Chapter 2 Hardware Configuration and Installation

This chapter contains the instructions to configure and install the VXI-SB2020 interface kit. The
instructions are given in the order that you should perform them. A summary of the steps is as
follows:

1. Unpack the SB-MXI and VXI-MXI.

2. Install the SB-MXI hardware.

3. Configure the VXI-MXI hardware.

4. Install the VXI-MXI hardware.

5. Connect the MXIbus cable.

Step 1. Unpack the SB-MXI and VXI-MXI

Follow these steps when unpacking your SB-MXI board and VXI-MXI module:

1. Before attempting to configure or install the SB-MXI and VXI-MXI, inspect the shipping
container and its contents for damage. If damage appears to have been caused in shipment,
file a claim with the carrier. Retain the packing material for possible inspection and/or for
reshipment.

2. Verify that the pieces contained in the package you received match the kit parts list. (See
Chapter 1 of this manual.) Do not remove the boards from their plastic bags at this point.

3. Your SB-MXI board and VXI-MXI module are shipped packaged in antistatic plastic bags to
prevent electrostatic damage. Some of the circuitry on the SB-MXI and VXI-MXI use
CMOS technology and can be damaged by electrostatic discharge. Before removing the
boards from their antistatic bags, touch the bags to a metal part of your computer chassis.

4. As you remove the SB-MXI and VXI-MXI from their bags, be sure to handle them only by
their edges. Avoid touching any of the IC components or connectors. Inspect them for loose
components or any other sign of damage. Notify National Instruments if either board appears
damaged in any way. Do not install equipment that appears to be damaged.

Hardware Configuration and Installation Chapter 2

Step 2. Install the SB-MXI Hardware

The SB-MXI does not have any jumpers or switches for configuring the hardware. The base
address of the SB-MXI is determined by the geographic mechanism provided by the SBus. The
SB-MXI uses SBus interrupt level 3, which it can share with other SBus boards.

Before you install the SB-MXI, notice that some MXIbus cable connector hoods are slightly
wider than most standard connector hoods and might interfere with other cables installed in
adjacent SBus slots. Normally, this will be a problem only if the cable connector hoods for the
adjacent slots are also oversized. When choosing an SBus slot in which to install the SB-MXI,
verify that the MXIbus cable connector will not interfere with cables and connectors in other
SBus slots. If necessary, reposition the boards in the system to prevent cabling conflicts. It may
also help to install the SB-MXI in one of the end slots so that you will have to contend with the
cable connectors of only one other board.

If you cannot configure the SB-MXI to co-exist in an existing SBus system by repositioning the
boards, you can use one of the MXIbus cable options with a straight-point connector hood on the
cable end that attaches to the SB-MXI. The straight-point connector hood is narrower than the
MXIbus dual-connector arrangement and provides an easier fit for many system configurations.
However, this approach requires that the SB-MXI be the first device in the MXIbus daisy-chain
because a cable with a straight-point connector end cannot accept another MXIbus cable to
propagate the bus. Remember that you must configure the first device in the MXIbus daisy­chain to be the MXIbus System Controller.

The following instructions are general installation instructions. Consult the user or technical
reference manual of your Sun workstation for specific instructions and warnings.

1. Plug in your Sun workstation before installing the SB-MXI. The plug grounds the system
unit and protects it from electrical damage while you are installing boards.

Warning: To protect both yourself and the Sun from electrical hazards, the system

unit should remain off until you are finished installing the board.

2. Remove the cover of the system unit.

3. Select any available SBus slot and remove the sheet-metal protector plate that covers the slot.

4. Before picking up the SB-MXI, touch the metal part of the power supply case inside the
computer to discharge any static electricity that might be on your clothes or body.

5. Depending on the type of Sun workstation, you need to select one of the following methods
for installing the SB-MXI. The difference is in regard to the mounting plate on the SB-MXI.

a. For most older Sun workstations, slide the SB-MXI at an angle into the back panel of the

system unit while making sure the mounting plate on the SB-MXI hooks into the holes on
the back panel of the system unit.

b. Most newer Sun workstations cannot accept the top part of the mounting plate on the

SB-MXI. This piece has tabs on either end and is fastened to the mounting plate by two
screws. Remove this piece before attempting to install the SB-MXI.
