ProDAQ 3020 USB 2.0 VXIbus Slot-0 Interface User Manual 3020-XX-UM
Copyright, © 2003 Bustec Production Ltd. Page 7 of 60
1. Introduction
The USB is a high-speed cable bus that supports data exchange between a host computer
and a wide range of simultaneously accessible peripherals. The ProDAQ 3020 USB 2.0
VXIbus Slot-0 Interface provides a direct link between the USB and the VXI backplane.
This manual describes the implementation, configuration and use of the interface.
1.1 Requirements
To set up and use the ProDAQ 3020 USB 2.0 VXIbus Slot-0 Interface, you need the
following:
A PC compatible computer running Windows 2000®or Windows XP®
A USB 1.1 or USB 2.0 compatible host controller
A VXI mainframe
The ProDAQ 3020 USB 2.0 VXIbus Slot-0 Interface
USB cable
ProDAQ Driver CD
1.1.1 The ProDAQ 3020 USB 2.0 VXIbus Slot-0 Interface
The ProDAQ 3020 USB 2.0 VXIbus Slot-0 Interface is a C-size, register based VXIbus
module providing a direct link between the high-speed USB 2.0 bus and the VXI
backplane. Data packages sent and received via the USB bus will be either translated into
accesses on the VXIbus or can be used to control the configuration and Slot-0 capabilities
of the ProDAQ 3020. The ProDAQ 3020 can automatically detect whether it is installed in
the left most slot of a VXI mainframe (slot “0”) and will enable or disable its Slot-0
capabilities accordingly.
1.1.2 The Host Computer
The ProDAQ 3020 Interface together with the USB controller allows your host computer to
perform as if it is plugged directly into the VXI backplane. It needs to be equipped with a
USB 1.1 or USB 2.0 compatible host controller, either already build-in into the
motherboard or via expansion cards. The drivers and software provided are for Pentium
based PC compatible computers.
Note
The host controller need to be already installed into and recognized by your
system. Bustec Production Inc. does not provide drivers for any USB component
other then the ProDAQ 3020 Interface itself. Please contact the manufacturer of
your motherboard or expansion card for suitable USB drivers for your operating
system.

3020-XX-UM ProDAQ 3020 USB2.0 VXIbus Slot-0 Interface User Manual
Page 8 of 60 Copyright, © 2003 Bustec Production Ltd.
Note
USB 1.0 compatible host controllers are not supported. USB 1.1 compatible host
controllers are limited to a maximum bus speed of 12 Mb/s. To achieve full
performance with the ProDAQ 3020 Interface, a USB 2.0 host controller is required.
1.1.3 The VXI Mainframe
The ProDAQ 3020 USB 2.0 VXIbus Slot-0 Interface is a single-slot wide, C-size VXI
module, which can reside in any slot of a C-size or D-size VXI mainframe. It will
automatically detect whether it is located in the left most slot of the mainframe (slot “0”)
and will enable or disable its Slot-0 capabilities accordingly, avoiding conflicts with the
backplane and other modules.
Note
Being a C-size module, the ProDAQ 3020 does not provide a P3 connector as used
in D-size mainframes. If used as a slot-0 controller in a D-size mainframe, it cannot
provide the necessary control for instruments using the additional features of the
P3 connector (CLK100, Star Trigger, add. Trigger and Local Bus Lines).
1.1.4 The USB Cable
To connect the ProDAQ 3020 USB2.0 VXIbus Slot-0 Interface to your host computer, use
the USB A-to-B high-/full-speed cable provided. You can connect the ProDAQ 3020 to any
of the USB ports your host computer/expansion board provides. Alternatively, if you are
using a USB hub to connect several USB devices to your computer, you may connect the
ProDAQ 3020 to a port on the hub.
Note
If you are using an additional USB hub to connect the ProDAQ 3020 to your
computer, the hub must be USB 1.1 or 2.0 compatible. To achieve full performance,
the hub must be able to support the high-speed mode as specified by the USB 2.0
standard. In general, using multiple devices connected to the same host controller
port may decrease the performance of your system.

2. Installation and Configuration
The ProDAQ 3020 USB 2.0 VXIbus Slot-0 Interface is a single slot, C-size VXIbus
instrument and can be installed in any slot of a standard C-size VXI mainframe. To be
Slot-0 controller for the VXIbus system, it must be installed in the leftmost slot of the VXI
mainframe (slot “0“). If it is installed in any other slot of a VXI mainframe, all slot-0
capabilities (MODID, CLK10, etc.) will be automatically turned off.
Note:
The ProDAQ 3020 USB 2.0 VXIbus Slot-0 Interface does not extend the VXI
backplane between mainframes in a multi-mainframe system. This means that
devices sharing the local bus must be installed in the same mainframe.
To install the ProDAQ 3020 USB 2.0 VXIbus Slot-0 Interface and the necessary software
on your system, use the installation sequence as described in this chapter:
Step 1: Unpacking and Inspection
Step 2: Installing the VISA Library
Step 3: Installing the ProDAQ 3020 Interface
Step 4: Installing the ProDAQ 3020 USB Driver
2.1 Unpacking and Inspection
All ProDAQ modules are shipped in an antistatic package to prevent any damage from
electrostatic discharge (ESD). Proper ESD handling procedures must always be used
when packing, unpacking or installing any ProDAQ module, ProDAQ plug-in module or
ProDAQ function card:
Ground yourself via a grounding strap or similar, e.g. by holding to a grounded
object.
Remove the ProDAQ module from its carton, preserving the factory packaging
as much as possible.
Discharge the package by touching it to a grounded object, e.g. a metal part of
your VXIbus chassis, before removing the module from the package.
Inspect the ProDAQ module for any defect or damage. Immediately notify the
carrier if any damage is apparent.
Only remove the module from its antistatic bag if you intend to install it into a VXI
mainframe or similar.
When reshipping the module, use the original packing material whenever possible. The
original shipping carton and the instrument’s plastic foam will provide the necessary
support for safe reshipment. If the original anti-static packing material is unavailable, wrap
the ProDAQ module in anti-static plastic sheeting and use plastic spray foam to surround
and protect the instrument.

You can connect the ProDAQ 3020 directly to your host controller. If you want to use
multiple 3020 or other USB devices in your system, you can use multiple free host ports
or, if necessary, a USB hub:
Figure 5 - USB Configurations
The USB physical interconnect is a tiered star topology with a hub at the center of each
star. Therefore new devices can be added either on the same tier, as long as ports are
available, or one of the ports can be used to connect to a new hub, providing the center for
a new tier. The USB standard allows for up to seven tiers per system.

The center of the first tier is always the controller/hub in the computer. This means that up
to five levels of USB hubs can be added. The last tier (tier seven) does only allow
functions (devices) in it.
Figure 6 - USB Bus Topology
USB 2.0 host controllers and hubs provide capabilities so that full-speed and low-speed
data can be transmitted at high-speed between the host controller and the hub, but
transmitted between the hub and the device at full-speed or low-speed. This capability
minimizes the impact that full-speed and low-speed devices have upon the bandwidth
available for high-speed devices.

2.5 Configuring the ProDAQ 3020 for the VISA Library
The VISA library uses interface names and numbers to access available hardware
interfaces. In order to enable the VISA library to use a ProDAQ 3020 interface, which is
connected to a host PC for the first time, a valid interface name and number must be
assigned to this device. The assigned interface name and number will be stored internally
in the configuration for this ProDAQ 3020 interface together with its serial number and will
be used for this device whenever it is connected to this host.
To assign an interface name/number and configure the ProDAQ 3020, connect the USB
interface cable between one USB port of the host PC and the USB port on the ProDAQ
3020 front panel and turn on the VXI mainframe.
From the VXIplug&play program group created during the installation of the VISA library,
select “VISA Configuration Utility” (“Start” “VXIPNP” “VISA Configuration Utility”).
This will start the configuration tool for the VISA library and attached hardware interfaces.
Figure 10 - VISA Library Configuration Utility
To add a new interface, select “Add Interfaces”. A new dialog “Available Interfaces” is
shown with a list of unconfigured devices found in the system. ProDAQ 3020 interfaces
appear as interfaces of the type “VXI” together with a description containing the serial
number of the device (see Figure 11, ProDAQ 3020 Ser. No. 3201003). If the 3020
detected features the optional on-board GPIB interface (ProDAQ 3020-AB and ProDAQ
3020-BB only), the GPIB interface will appear in the list of available interfaces as a
separate interface of the type “GPIB”, again with a description containing the serial number
of the device (see Figure 11, ProDAQ 3020 Ser.No. 30201018).
