Ways to Install VXI Instruments
Instruments
This step shows two ways to install VXI instruments in mainframes.
The first way is to use the HP VXI Installation Consultant (HP VIC).
The second way is to install using the procedures in this step.
• If you want to use HP VIC, go to “Installation Using HP VIC”.
HP VIC is a utility that provides a structured way to configure
and install VXI instruments, and to check the installation.
• If you do not want to use HP VIC, go to “Installation Without
Using HP VIC”.
Installation Using HP VIC
To use HP VIC:
1 Turn mainframe and PC power OFF. Connect the interface cable
(HP-IB or IEEE-1394) from the Slot 0 card (in the mainframe) to
the PC I_O card (in the PC). Turn PC power ON (leave mainframe
power OFF).
2 Insert the Hewlett-Packard Universal Instrument Drivers CD into
the CD-ROM drive and wait a few seconds for the setup
instructions to appear.
3 If the setup screen does not appear in a few se conds, clic k Start|Run
and then type <drive>: setup.exe in the Run box , where dr ive is your
CD-ROM drive.
4 When the main menu appears, click Launch Installer or View
Manuals. Click Next on the next screen and Yes on the third screen
to go to the Choose Type of Installation screen (see Figure 15).
22 Installing External PC VXI Systems
Figure 15. Choose Type of Installation Screen
5 From the Choose Type of Installation screen, click the RUN
HP VIC... icon to display the Welcome to HP VIC screen.
6 From this screen, click Ne w--> and follow t he on-screen i nstructions
to install and check your VXI instruments and to (optionally) print
the results.
7 If you have HP-IB Rack & Stack instruments or a termina l to install,
go to St ep 3- 4: Connect Interface Cable . Otherwise, go to Step 3-5: Interconnect Mainframes.
Installation Without Using HP VIC
1 The first step to install VXI instruments is to select the mainframe
slot to use for each VXI instrument. See the applicable Mainframe
User’s/Service Manual or Instrument User’s Guide for guidelines.
2 When you have selected a slot for an instr ument, enter the instr ument
model number , n ame, a nd serial number for the in st rument in Table
1. (The instrument serial number is located on the side of the
instrument.) Do this for all instruments to be installed.
NoteFor pre-configured systems, the Installed VXI Instruments List in the
Owner’s Pack lists instrument model number, name, logical address, and
serial number for each installed VXI instrument.

Set VXI Instrument Logical Addresses
1 When you have selected the slot for each VXI instrument, the next
step is to set the i nstrument logical addresse s (LADDR) as re quired.
In general, you can use the factory-set (default) logical addresses.
2 If you need to set other logical addresses, use the following
guidelines. See the applicable Mainframe User’s/Service Manual
or Instrument User’s Guide for details.
• The logical address for each VXI i n st ru ment is set by the Logical
Address (LADDR) switch on the ins trument. The logic al addr ess
value is the sum of the values of the logical address switches set
to the closed position (see Figure 16).
• For HP-IB (HP E1406A Command Module) systems, each VXI
instrument must have a separate logical address and the logical
address must be a multiple of 8 (8, 16, 24, etc.).
• For IEEE-1394 (HP E8941A Interconnect) systems, each VXI
instrument must have a separate logical address but the logical
address does not have to be a multiple of 8.
• A multimeter and one or more multiplexers can be used to form
a scanning multimeter. In this case, the instruments must be in
adjacent mainframe slots and must have sequential logical
addresses (see Figure 17). In addition, for HP E1406A systems
the multimeter must have a logical address that is a multiple of 8.
3 When you have selected the logical address for an instrument, set
the address using the LADDR switch on the instrument. Then,
record the logical address in Table 1. Repeat for each instrument.
Example: Setting Multimeter Logical Address
Figure 16 shows an HP E1411B multimeter with the Logical Address
switch set to 24. Since switch 3 (logical value = 8) and switch 4
(logical value = 1 6 ) a re b o th closed, the sum of the lo gic al values (24)
is the logical addres s for t he HP E1411B. See the HP E1326B/E1411B User’s Guide for details.

Example: Scanning Multimeter Logical Addresses
Figure 17 shows an HP E1406A installed in Slot 0 and VXI
instruments installed in slots 1 through 4 of an HP E8404A VXI
mainframe. The HP E1411B multimeter and the two HP E1460A
multiplexers form a scanning multimeter since they are in adjacent
mainframe slots, and they have sequential (24, 25, 26) logical
addresses.
Since this is an HP-IB (HP E1406A) system, the HP E1411B
multimeter must have a logical address that is a multiple of 8 (24 in
this case). For an IEEE-1394 (HP E8491A) system, the three
instruments must still be in adjacent mainframe slots, but could have
any three sequential logical addresses (such as 17, 18, 19).
1 As required, perform Logical Address switch (and other switch)
setting changes for each VXI instrument. See the previous step and
the applicable Instrument User’s Guide for details.
2 Turn mainframe power OFF. Then, install each VXI instrument
in the slot(s) you previously identified. Figure 18 shows the
hardware connected at the end of this step.
3 Turn mainframe power ON and observe each instrument’s power-
on display sequence (if any). See the applicable Instrument User’s
Guide for details. Then, turn mainframe power OFF.

Panels
NoteTo use an Instrume nt Soft Front Panel, the instrument must have a Soft
Instrument Soft Front Panels (SFP) are included as part of the
instrument VXIplug&play drivers, and provide a virtual “front panel”
for selected instruments. A soft front panel is activated from the
Vxipnp program group when you click the applicable SFP icon
(Start|Programs| Vxipnp|<instrument> (SFP)).
Front Panel file loaded in the Vxipnp program group. See Step 4-2: Install VXIplug&play Drivers for information on loading Soft Front Panels.
Some features of Soft Front Panels (SFP) are:
• A SFP is a virtual “front panel” for the instrument. Thus, you
can use the SFP to communicate with the instrument and to
return results.
• SFPs return the slot number (for some instruments) and the
instrument description, including the logical address.
• You can use SFPs to set instrument functions, ranges, and other
features without writing a single line of code.
Example: Communicate Using HP E1411B Soft Front Panel
For this example, we will use an HP E1411B multimeter and the
HP E1411 Soft Front Panel to measure the voltage of a 9V battery
connected to the HP E1411B terminals. To run this example:
1 Turn mainframe power OFF and connect the battery to the HI and

6-3: Create Test
Programs
When you have defined connections from your product to the VXI
instruments, the next s tep is to define the specif ic test(s) for your
product. For example, tests could include voltage, current, or
resistance measurements, strain measurements, etc. Create the
specific product tests required for your product.
Getting Started Using Example Programs
When you have defined the tests for your product, the next step is
to create programs to implement the tests. As desired, you can copy
and use the example programs included on the Hewlett-Packard Universal Instrument Drivers CD to get started creating your test
programs. In addition (for HP-IB) you can program your system
using SCPI commands. See Programming Using SCPI Commands for
details.
Where are the Example Programs?
Several example programs are included on the Hewlett-Packard
Universal Instrument Drivers CD or in the Vxipnp directory. You can
copy and use or modify t hese progr ams for you r applic ation. Programs
are in Visual C/C++, Visual Basic, and HP VEE.
1 For instruments that have an HP VXIplug&play driver, Visual
C/C++ and Visual Basic example programs are contained in the
instrument’s VXIplug&play Help File. To access these programs,
click Start|Programs |Vxipnp| instrument help icon. See “Using
Visual C/C++ and Visual Basic Programs” for details.
2 If you use HP VEE, some HP VEE example programs are
located in the examples directory of the Hewlett-Packard Univ ersal Instrument Drivers CD. This directory includes C and/or HP VEE
programming examples grouped by instr ument numbe r. See “Using
HP VEE Example Programs” for details.
Using HP VEE Example Programs
1 Be sure all applicable VXIplug&play drivers have been installed
on the PC (see Step 4-2: Install VXIplug&play Drivers).
2 As required, configure the VXI instruments with the HP VEE
Instrument Manager (se e Step 5-3: Use HP VEE Instrument Manager).
3 Insert the Hewlett-Packard Universal Instrument Drivers CD
into the CD ROM drive and wait a few seconds for the setup
instructions to appear.
Installing External PC VXI Systems 45
4 If the setup screen does not appear in a few seconds, click Start|
Run and type <drive>:s etup.e xe in t he Run bo x, where drive is your
CD ROM drive.
5 To access HP VEE programs from the CD, use Windows NT
Explorer (or equivalent) to access the examples directory on the
CD. This directory includes C and/or HP VEE programming
examples grouped by instrument number. For example, to access
the HP VEE E1411 example program, the path is <drive>:| examples\hpe1411\1411.
6 As required, see the applicable Instrument User’s Guide for details
on instrument addressing, operation, settings, modes, etc.
NoteOnline versions of most instrument manuals are included on the Hewlett-
Packard Universa l Instrument Driver CD. To access a specific online
instrument manual, run the CD and click VIEW PRODUCT MANUALS
from the Choose Type of Installation screen. Then, select the manual
you want to view.
7 Copy, run, and modify the example programs as desired. We
suggest you copy the HP VEE example programs from the CD to
your HP VEE working direct ory se t up dur ing HP VEE insta llation.
8 When you run an example program, you may be prompted to add
device drivers and/or to save the instrument configuration.
However, doing this ma y overwrite the default inst rument
configuration file (vee.io). If you do not want the vee.io file to be
overwritten, you can do one of two things:
• In Windows Explorer, re-name the vee.io file to another file
(such as vee_mine.io, etc.) BEFORE you run the example
program. After you run the program, delete the new vee.io file
and restore your configuration file to its original name (vee.io).
You will need to do this if you want to run the example pr ograms
shipped with HP VEE.
OR
• Click NO when asked i f you want t o s ave t he changes. When you
exit HP VEE, the default configuration file (vee.io) will remain
unchanged. For this action, you will not need to rename vee.io.
9 Repeat Steps 5 through 8 for each VXI instrument to be
programmed using HP VEE.
46 Installing External PC VXI Systems
Example: HP E1411 HP VEE Program
An HP VEE example program for the HP E1411B Digital Multimeter
that is on the Hewlett-Packard Universal Instrument Drivers CD is
entitled 1411. To access this program, select <drive>:\examples\ hpe1411\1411, where drive is the CD-ROM drive letter.
For this example, we will copy the 1411 program to the HP VEE

Determine Instrument Slot/Logical Address
Instruments
1 The first step to install VXI instruments is to select the mainframe
slot to use for each VXI instrument. See the applicable Mainframe
User’s/Service Manual or Instrument User’s Guide for guidelines.
2 When you have selected a slot for an instr ument, enter the instr ument
model number , n ame, a nd serial number for the in st rument in Table
1. (The instrument serial number is located on the side of the
instrument.) Do this for all instruments to be installed.
NoteFor pre-configured systems, the Installed VXI Instruments List in the
Owner’s Pack lists instrument model number, name, logical address, and
serial number for each installed VXI instrument.

Set VXI Instrument Logical Addresses
1 When you have selected the slot for each VXI instrument, the next
step is to set the i nstrument logical addresse s (LADDR) as re quired.
In general, you can use the factory-set (default) logical addresses.
2 If you need to set other logical addresses, use the following
guidelines. See the applicable Mainframe User’s/Service Manual
or Instrument User’s Guide for details.
Installing Embedded PC VXI Systems 59
• The logical address for ea ch VXI i nst ru me nt i s se t by t he Logical
Address (LADDR) switch on the ins trument. The logic al addr ess
value is the sum of the values of the logical address switches set
to the closed position (see Figure 12).
• For HP-IB (HP E1406A Command Module) systems, each VXI
instrument must have a separate logical address and the logical
address must be a multiple of 8 (8, 16, 24, etc.).
• For IEEE-1394 (HP E8941A Interconnect) systems, each VXI
instrument must have a separate logical address but the logical
address does not have to be a multiple of 8.
• A multimeter and one or more multiplexers can be used to form
a scanning multimeter. In this case, the instruments must be in
adjacent mainframe slots and must have sequential logical
addresses (see Figure 13). In addition, for HP E1406A systems
the multimeter must have a logical address that is a multiple of 8.
3 When you have selected the logical address for an instrument, set
the address using the LADDR switch on the instrument. Then,
record the logical address in Table 1. Repeat for each instrument.
Example: Setting Multimeter Logical Address
Figure 12 shows an HP E1411B multimeter with the Logical Address
switch set to 24. Since switch 3 (logical value = 8) and switch 4
(logical value = 1 6 ) a re b o th closed, the sum of the lo gic al values (24)
is the logical addres s for t he HP E1411B. See the HP E1326B/E1411B User’s Guide for details.

Example: Scanning Multimeter Logical Addresses
Figure 13 shows an HP E62 34A e mb edded PC installed in Slot s 0 and
1 and VXI instrumen ts i nst al le d i n s lo ts 3 thr oug h 6 of an HP E8404A
VXI mainframe. The HP E1411B multimeter and the two HP E1460A
multiplexers form a scanning multimeter since they are in adjacent
mainframe slots, and they have sequential (24, 25, 26) logical
addresses.
Since this is an HP-IB (HP E1406A) system, the HP E1411B
multimeter must have a logical address that is a multiple of 8 (24 in
this case). For an IEEE-1394 (HP E8491A) system, the three
instruments must still be in adjacent mainframe slots, but could have
any three sequential logical addresses (such as 17, 18, 19).
1 As required, perform Logical Address switch (and other switch)
setting changes for each VXI instrument. See the previous step and
the applicable Instrument User’s Guide for details.
2 Turn mainframe power OFF. Then, install each VXI instrument
in the slot(s) you previously identified. Figure 14 shows the
hardware connected at the end of this step.
3 Turn mainframe power ON and observe each instrument’s power-
on display sequence (if any). See the applicable Instrument User’s
Guide for details. Then, turn mainframe power OFF.

70 Installing Embedded PC VXI Systems
Some features of Soft Front Panels (SFP) are:
• A SFP is a virtual “front panel” for the instrument. Thus, you
can use the SFP to communicate with the instrument and to
return results.
• SFPs return the slot number (for some instruments) and the
instrument description, including the logical address.
• You can use SFPs to set instrument functions, ranges, and other
features without writing a single line of code.
Example: Communicate Using HP E1411B Soft Front Panel
For this example, we will use an HP E1411B multimeter and the
HP E1411 Soft Front Panel to measure the voltage of a 9V battery
connected to the HP E1411B terminals. To run this example:

NoteThis step assumes you have installed and configured your VXI hardware/
software and have verified communication between your PC and the VXI
equipment.
Since your product to be connected will require individualized tests and
connections, this step only provides general guidelines and shows where
example programs are available. You will need to design the specific tests
and/or programs for your system.

NoteIf you do not use mass interconnects, your product will be connected
The first step in designing your product (typically a Unit Under Test
(UUT)) connections is to decide if you will use Mass Interconnects,
such as a fixture syst em.
If your system uses interconnects, define the mass interconnect
connections to the VXI mainframe and to your product. See the
applicable Mass Interconn ect Installat ion instruction s to install the
interconnects.

define these connections. In this case, skip to Record Your Product
Connections.
Figure 36 shows one way mass interconnects (ICAs and ITAs)
can be used to connect your product to the VXI instruments in the
mainframe. You can use the table in the next step to record
connections from your product to the VXI instruments via the
ICAs and ITAs.

Defining Tests for Your Product
Tests
6-3: Create Test
Programs
When you have defined connections from your product to the VXI
instruments, the next s tep is to define the specif ic test(s) for your
product. For example, tests could include voltage, current, or
resistance measurements, strain measurements, etc. Create the
specific product tests required for your product.
Getting Started Using Example Programs
When you have defined the tests for your product, the next step is
to create programs to implement the tests. As desired, you can copy
and use the example programs included on the Hewlett-Packard Universal Instrument Drivers CD to get started creating your test
programs.
Where are the Example Programs?
Several example programs are included on the Hewlett-Packard
Universal Instrument Drivers CD or in the Vxipnp directory. You can
copy and use or modify t hese progr ams for you r applic ation. Programs
are in Visual C/C++, Visual Basic, and HP VEE.
1 For instruments that have an HP VXIplug&play driver, Visual
C/C++ and Visual Basic example programs are contained in the
instrument’s VXIplug&play Help File. To access these programs,
click Start|Programs |Vxipnp|instrument help icon. See “Using
Visual C/C++ and Visual Basic Programs” for details .
2 If you use HP VEE, some HP VEE example programs are
located in the examples directory of the Hewlett-Packard Univ ersal Instrument Drivers CD. This directory includes C and/or HP VEE
programming examples grouped by instr ument numbe r. See “Using
HP VEE Example Programs” for details.
Using HP VEE Example Programs
1 Be sure all applicable VXIplug&play drivers have been installed
on the PC (see Step 4-2: Install VXIplug&play Drivers).
2 As required, configure the VXI instruments with the HP VEE
Instrument Manager (se e Step 5-3: Use HP VEE Instrument Manager).
3 Insert the Hewlett-Packard Universal Instrument Drivers CD
into the CD ROM and wait a few seconds for the setup instructions
to appear.
80 Installing Embedded PC VXI Systems
4 If the setup screen does not appear in a few seconds, click Start|
Run and type <drive>:s etup.e xe in t he Run bo x, where drive is your
CD ROM drive.
5 To access HP VEE programs from the CD, use Windows NT
Explorer (or equivalent) to access the examples directory on the
CD. This directory includes C and/or HP VEE programming
examples grouped by instrument number. For example, to access
the HP VEE E1411 example program, the path is <drive>:| examples\hpe1411\1411.
6 As required, see the applicable Instrument User’s Guide for details
on instrument addressing, operation, settings, modes, etc.
NoteOnline versions of most instrument manuals are included on the Hewlett-
Packard Universa l Instrument Driver CD. To access a specific online
instrument manual, run the CD and click VIEW PRODUCT MANUALS
from the Choose Type of Installation screen. Then, select the manual
you want to view.
7 Copy, run, and modify the example programs as desired. We
suggest you copy the HP VEE example programs from the CD to
your HP VEE working direct ory se t up dur ing HP VEE insta llation.
8 When you run an example program, you may be prompted to add
device drivers and/or to save the instrument configuration.
However, doing this ma y overwrite the default inst rument
configuration file (vee.io). If you do not want the vee.io file to be
overwritten, you can do one of two things:
• In Windows Explorer, re-name the vee.io file to another file
(such as vee_mine.io, etc.) BEFORE you run the example
program. After you run the program, delete the new vee.io file
and restore your configuration file to its original name (vee.io).
You will need to do this if you want to run the example pr ograms
shipped with HP VEE.
OR
• Click NO when asked i f you want t o s ave t he changes. When you
exit HP VEE, the default configuration file (vee.io) will remain
unchanged. For this action, you will not need to rename vee.io.
9 Repeat Steps 5 through 8 for each VXI instrument to be
programmed using HP VEE.
Installing Embedded PC VXI Systems 81
Example: HP E1411 HP VEE Program
An HP VEE example program for the HP E1411B Digital Multimeter
that is on the Hewlett-Packard Universal Instrument Drivers CD is
entitled 1411. To access this program, select <drive>:\examples\ hpe1411\1411, where drive is the CD-ROM drive letter.
For this example, we will copy the 1411 program to the HP VEE
working directory. When HP VEE is run and the program is opened,
a display similar to Figure 37 appears. If you have an HP E1411B
DVM in your system, you can run this program and observe the
results. (Be sure you have configured the instruments as shown
in Step 5-3: Use HP VEE Instrument Manager.)
Using Visual C/C++ and Visual Basic Programs
You can program VXI instruments that have VXIplug&play drivers
using Visual C/C++ or Visual Basic and the online VXIplug&play
Help Files for VXI instruments. To use the example Visual C/C++
or Visual Basic programs:
1 Be sure all applicable VXIplug&play drivers have been in stalled on
