This chapter provides an overview of the VX1411A IntelliFrame Mainframe. It
includes installation and configuration information on user-installed options.
Product Description
The VX1411A IntelliFrame Mainframe is a 13-slot, C-size, VXIbus Mainframe.
It fully complies with the VXIbus Specification 1.4 requirements and is
VXIplug&play compatible. The mainframe has the following features:
H
Excellent available power for the majority of applications
H
Variable fan speed based upon operating ambient temperature
H
High quality auto-configuration backplane
H
EMI DIN shields for superior EMI protection
H
Optional adjustable rackmounts and cable tray
These features are explained in more detail in the following paragraphs.
Power Supply
The VX1411A IntelliFrame Mainframe provides all VXIbus voltages at levels
necessary for most ATE applications. The power supply has a volt-ampere
capacity of 1186 VA, with 700 watts is usable by VXI instrument modules at any
one time (refer to Appendix A: Power Budget Worksheet). The mainframe
accommodates exclusively digital applications, exclusively analog applications,
or combinations of both.
The power supply plugs directly into the rear of the mainframe and has no cables
to disconnect. The power supply can easily be replaced in less than three
minutes, minimizing downtime. The power supply automatically sets the ranges
for the appropriate input voltage and frequency.
Cooling
The VX1411A IntelliFrame Mainframe provides optimal cooling for all installed
modules. The mainframe is equipped with two efficient variable speed fans. The
fan speed can easily be manually switched from a low noise, variable speed to
full speed for maximum cooling. Fan speed varies with ambient air temperature:
H
Minimum speed <20C
H
Maximum speed >50C
H
Variable speed from 20 to 50C

Getting Started
Air is exhausted at the sides of the mainframe, allowing you to safely stack the
mainframe with other rackmount equipment. Additional equipment placed on or
positioned above the product will not restrict airflow nor will that equipment be
directly affected by exhaust air.
CAUTION. To prevent damage from over heating, make sure the ambient air
temperature inside the rackmount enclosure remains below 55C.
Cooling is not wasted on empty slots. IntelliGuides automatically direct air to
only those slots containing modules; empty slots are shut off. The mainframe
directs airflow across each installed module from the bottom to the top of each
slot. Baffles balance the airflow from the front to back and across occupied slots
in the mainframe.
You can easily remove the air filter from the rear of the mainframe. The fans can
be replaced without disassembling the entire mainframe.
Backplane
The VX1411A IntelliFrame Mainframe has an auto-configuration, solid-state
backplane that uses electronic jumpers for the IACK and BUS GRANT signal
lines. There are no jumpers to move or install on the backplane. This results in a
high quality backplane that is ideal for ATE systems that must be reconfigured
frequently. The backplane is installed with standard EMI DIN shields.
Full differential distribution of the CLK10 signals provides a clean timing source
for your VXIbus instruments.
Optional Rackmounts and
Cable Tray
You can order the VX1411A IntelliFrame Mainframe with user-installed
rackmounts and cable tray. The cable tray provides a means to conveniently route
cables from the front of the modules to the rear of the mainframe. Option 1U
includes a 1.75-inch connector butch plate. You can install Option 1U to provide
a 1.75-inch, 2.5-inch, or 4.25-inch deep cable tray.
The rackmount adapters let you recess the mainframe from the front panel
mounting surface at specified depths from 0.735 inches to 5.735 inches in
0.5-inch increments. Similarly, you can configure the mainframe to extend out of
the front of the rack at specified depths (0.57 inches to 5.57 inches in 0.5-inch
increments).
You can install the rackmount kits along with the cable tray to provide vertical
cable access to easily route cables to instruments above or below the mainframe
while keeping lead lengths as short as possible.
You can also install an optional Lexan door with the rackmount kit.

Installation
This section describes the procedures to install your mainframe. It includes
procedures for installing the mainframe with the rackmount or cable tray options.
This section does not include specific procedures for installing modules in the
mainframe. Refer to your module documentation for information regarding the
module installation instructions.
Site Considerations
The VX1411A IntelliFrame Mainframe is designed to operate on a bench or in a
rackmount environment. For proper cooling, allow at least 2 inches (5.1 cm) of
clearance on the rear and sides of the mainframe. Determine how you will use
your VX1411A IntelliFrame Mainframe and follow the appropriate installation
instructions. If you ordered your mainframe with the cable tray option and one of
the rackmount options, install the cable tray before installing the rackmount.
WARNING. To avoid personal injury, use care when lifting or moving the
mainframe to avoid personal injury while performing the installation procedures.
Cable Tray Installation
The IntelliFrameR mainframe comes a with a 0.75-inch cable access area on the
bottom of the mainframe. Use the following procedure to install your cable tray
option:
You will need a T-20 Torx and Phillips driver to install Options 1U or 2U.
Options 1U and 2U can be installed three different ways; without rails, with
rails, or with rails installed at 90_.
Figure 1–1 on page 1–7 and Figure 1–2 on page 1–8 show how to install
Option 1U (without rails, with rails, rails at 90_) to provide a cable tray depth of
1.75, 2.50, or 4.25 inches.
Figure 1–3 on page 1–9 and Figure 1–4 on page 1–10 show how to install
Option 2U (without rails, with rails, rails at 90_) to provide a cable tray depth of
3.50, 4.25, or 6.00 inches.
Both options come with butch plates to mount cable connectors at the rear of the
cable trays. The butch plate will not fit on Option 1U when the foot rails are not
used. You can modify the butch plate to accept cable connectors at the rear of the
mainframe. Specific instructions for modifying the butch plate are not given
since the locations, types, and size of connectors vary with each application.

Front Panel SYSReset
Activation
The IntelliFrameR mainframe provides you the ability to generate a backplane
SYSReset signal from the front panel. This feature allows you to reset the
complete VXI system without having to power down the mainframe. A
SYSReset activation is accomplished by pushing the right side (nonlighted side)
of the On/Standby power switch.
NOTE. If you decide to configure the front panel SYSReset, you should configure
the mainframe before installing the rackmount hardware. Refer to Appendix B:
Special Configuration Options for activation of this feature and then return to
this section to continue the installation procedures.
Rackmount Installation
The procedures for installing the rackmount kits are similar for the Option 1R
and 2R kits. You can install the Option 1R kit to either recess the mainframe
from the front of the mainframe rack or to extend it out of the mainframe rack.
However, you can only install the door for the Option 2R kit so that the
mainframe recesses into the rack.
The steps for installing the rackmount kits consist of installing the rackmount
hardware to the mainframe, and then installing the mainframe in the rack.
You will need the following tools to install the rackmount options:

Install the Mainframe
in the Rack
Use the following procedure to install the VX1411A IntelliFrame Mainframe in
the rack:
1. Identify the right and left slide-out track assemblies: find the date code label
on each assembly. The assembly to be mounted in the left side of the rack
(the side nearest the left side of the mainframe when it is mounted in the
rack) has a date code that ends with LH (for left hand). The right assembly
has a date code ending with RH.
2. Measure the distance between the front and rear rail of the rack.
3. Align the rear bracket to the right slide-out track as shown in Figure 1–6.
Note that the rear bracket has two pairs of mount-through holes. When
aligning the bracket and the track, select a pair of holes that mount the rear
bracket so the flange-to-flange distance (see Figure 1–6) matches the front
rail to rear rail spacing that you just measured in step 2.
NOTE. If necessary, refer to the rackmount kit instructions for detailed installation information.
4. Attach the rear bracket to the right slide-out track using two 10-32 screws
and a bar nut as shown in Figure 1–6. Leave the screws loose so that you can
adjust the overall length of the slide-out track assembly when installing the
mainframe in the rack.
5. Repeat steps 3 and 4 to assemble the left slide-out track assembly.

continue to slide the mainframe all the way back into the rack cabinet.
15. Tighten the four screws that you left loose at the rear of the rack when you
performed step 8 and pull the mainframe part way out of the rack. (Tighten
the 10-32 screws using 28 inch-lbs of torque.)
16. Be sure that the screws that you left loose at the front of the rack are loose
enough to allow the slide-out track assemblies to seek the normal positions.
17. Tighten the screws and push the mainframe all the way into the rack. If the
tracks do not slide smoothly, readjust the level using the method described in
steps 15 and 16. (Tighten the 10-32 screws using 28 inch-lbs of torque.)
18. Install the proper power cord at the rear of the mainframe.
NOTE. To ensure the mainframe is properly mounted in the rack do not tighten
the screws while installing the chassis track to the rack front rails. After all the
mounting screws have been installed shift the mainframe to the far right of the
rack, then tighten all the mounting screws. Refer to Figure 1–9 for screw

EMI Configurations
Perform the following steps if you intend to install the optional EMI Intermodule
shields and/or EMI filler panels. (Part numbers are listed under Optional
Accessories on page 5–8):
NOTE. It is only necessary to install the EMI intermodule shields if your VXIbus
module does not have EMI shielding. Backplane EMI DIN shields are standard.
1. Refer to Figure 1–13 and slide the EMI intermodule shields between the
grooves of the card guide on one side of each installed VXIbus module. This
is recommended to use with unshielded modules; the shielding may not be
compatible with some modules. The shield conforms with the VXI specification for intermodule shielding.
2. Install a blank EMI front panel for each empty slot making sure that the EMI
shielding is in contact with the adjacent front panel.

Functional Check and Performance Verification
Use the information in this section to determine that the VX1411A IntelliFrame
Mainframe operates properly. The functional check and performance verification
consist of checking the power supply voltages. To check these voltages you will
need an extender card and a digital voltmeter. Refer to Troubleshooting
Procedures on page 4–16 for extender card and digital voltmeter ordering
information. No adjustments are required for the VX1411A mainframe.
Connect one lead of the voltmeter to the pins of the extender card that is inserted
into slot 0 of the mainframe. Connect the reference lead of the voltmeter to one
of the ground pins. Compare each voltage reading to the values listed in
Table 1–4.

Operating Basics
This chapter provides a brief overview of the VX1411A IntelliFrame Mainframe
including illustrations and descriptions of switches, indicators, and connectors.
Figure 2–1 shows the front view of the VX1411A IntelliFrame Mainframe. All
of the mainframe slots are labeled on the top and bottom of the mainframe.
Slot 0 is reserved for the mainframe controller; all other slots are available for
any VXIbus modules.
IntelliGuides on the bottom of each slot automatically open when you install a
module. The guides remain closed for empty slots to direct airflow only where it
is needed.

Operating Basics
The On/Standby switch on the top-left corner of the front panel applies DC
voltages to the mainframe. The switch is a momentary contact switch. The
switch is lighted when DC voltages are applied to the mainframe. This switch
can also generate a SysReset on the VXI Backplane, refer to Appendix B:
Special Configuration for configuration information.
NOTE. Disconnecting the power cord provides the mainframe’s voltage disconnect. Even when powered off by the Power/Standby switch the power supply
circuits are connected to primary power.
Figure 2–2 shows the rear view of the standard VX1411A IntelliFrame Mainframe.
The AC power connector is located on the bottom left side on the rear of the
mainframe. The AC fuse holder is located just above the power connector.
The chassis ground screw (if installed) can be used to connect multiple
mainframes to a common ground point.
The fan filter is located on the back of the mainframe. The filter slides easily into
the mainframe; there is no need to remove any covers to replace or clean the fan
filter. Refer to the maintenance section page 4–3.

Operating Basics
Fan Speed Control
The Fan Speed switch controls the speed of the system cooling fans. When the
switch is set to the variable position, the fans are set to a variable speed to reduce
fan noise. The fans are automatically adjusted by the mainframe to minimize fan
noise and provide appropriate cooling. When the switch is in the FULL position,
the fans operate at full speed.
The fans’ speed varies by the level of the ambient air temperature:
H
Air temperatures less than 20C the fans operate at minimum speed
H
Air temperatures between 0 to 50C the fans speed linearly increase with
temperature
H
Air temperatures greater than 50C fans operate at full fan speed
The power supply is adequately cooled for any load condition when the fan
speed is placed in either the VAR or FULL speed position.

Theory of Operation
This section provides a brief overview of the theory of operation for the
VX1411A IntelliFrame Mainframe. Figure 4–12 shows the functional block
diagram of the mainframe and the major components.
The VX1411A IntelliFrame Mainframe contains the following major components:
H
Power supply
H
Backplane
Power Supply. The power supply provides all voltages and currents to the
mainframe. The power supply connects to the backplane at P25, P26, P27, and
P28. The power supply can be replaced as a single unit.
Backplane. The Backplane (A4) provides all the connections to module slots 0
through 12 in the mainframe. It also has connections to all other circuit boards
and modules in the mainframe.
The front panel On/Standby DC switch connects to J22 at the top of the
backplane.
The backplane connects to the Power Supply at J25 and J28. Connector P25
supplies power to the fans from the backplane via the fan control cable.
The VX1411A IntelliFrame Mainframe provides optimal cooling for all installed
modules. The mainframe is equipped with two efficient variable speed fans. The
fan speed can easily be manually switched from a low noise, variable speed to
full speed for maximum cooling. Fan speed varies with ambient air temperature:

Appendix B: Special Configuration
This appendix contains information for configuring your IntelliFrame
Mainframe for specific situations not documented earlier in this manual. This
special configuration requires you to disassemble parts of the mainframe to
access cables and circuit boards. Refer to the Maintenance chapter for detailed
information on the assembly and disassembly procedures. You may also need to
refer to the exploded views.
The information in this section is intended for use by qualified service personnel.
Read the General Safety summary and Service Safety Summary at the front of
this manual and the static precautions on page 4–1 before attempting any
procedures in this appendix. Refer to the Operating Basics chapter for information on the location of controls, indicators, and connectors used with the
mainframe.
CAUTION. To avoid damage from high currents on the backplane, always power
off the mainframe and disconnect the power cord before performing any of the
configuration procedures for the mainframe described in this appendix.
Front Panel SYSReset Cable Connector Configuration
The IntelliFrame Mainframe front panel switch cable connector must be
configured as shown in Figure B–1 before the SYSReset feature can be utilized.
Perform the following procedures to activate the SYSReset feature.
1. Remove the mainframe cover.
2. Cut the tie wrap that secures the SYSReset connector to the front panel
switch cable.
3. Connect the SYSReset connector to J29 on the backplane circuit board.
4. Replace the mainframe cover.

Glossary
The terms in this glossary are defined as used in the VXIbus System. Although
some of these terms may have different meanings in other systems, it is
important to use these definitions in VXIbus applications. Terms which apply
only to a particular instrument module are noted. Not all terms appear in every
manual.
ACFAIL*
A VMEbus backplane line that is asserted under these conditions: 1) by the
mainframe Power Supply when a power failure has occurred (either ac line
source or power supply malfunction), or 2) by the front panel ON/
STANDBY switch when switched to STANDBY.
A-Size Card
A VXIbus instrument module that is 100.0 × 160 mm × 20.32 mm (3.9 ×
6.3 in × 0.8 in), the same size as a VMEbus single-height short module.
Asynchronous Communication
Communications that occur outside the normal “command-response” cycle.
Such communications have higher priority than synchronous communication.
Backplane
The printed circuit board that is mounted in a VXIbus mainframe to provide
the interface between VXIbus modules and between those modules and the
external system.
B-Size Card
A VXIbus instrument module that is 233.4 × 160 mm × 20.32 mm (9.2 ×
6.3 in × 0.8 in), the same size as a VMEbus double-height short module.
Bus Arbitration
In the VMEbus interface, a system for resolving contention for service
among VMEbus Master devices on the VMEbus.
Bus Timer
A functional module that measures the duration of each data transfer on the
Data Transfer Bus (DTB) and terminates the DTB cycle if the duration is
excessive. Without the termination capability of this module, a Bus Master
attempt to transfer data to or from a non-existent Slave location could result
in an infinitely long wait for the Slave response.
Butch Plate
A connector plate that optionally connects to the rear of the cable tray
options. The plate can be modified to accept panel mount connectors thus
reducing the number of cables under the VX1411A IntelliFrame Mainframe.

Glossary–1
Glossary
Client
In shared memory protocol (SMP), that half of an SMP channel that does not
control the shared memory buffers.
CLK10
A 10 MHz, ±100 ppm, individually buffered (to each module slot),
differential ECL system clock that is sourced from Slot 0 and distributed to
Slots 1–12 on P2. It is distributed to each module slot as a single source,
single destination signal with a matched delay of under 8 ns.
CLK100
A 100 MHz, ±100 ppm, individually buffered (to each module slot),
differential ECL system clock that is sourced from Slot 0 and distributed to
Slots 1–12 on P3. It is distributed to each module slot in synchronous with
CLK10 as a single source, single destination signal with a maximum system
timing skew of 2 ns, and a maximum total delay of 8 ns.
Commander
In the VXIbus interface, a device that controls another device (a servant). A
commander may be a servant of another commander.
Command
A directive to a device. There are three types of commands:
In Word Serial Protocol, a 16-bit imperative to a servant from its commander.
