INTRODUCTION

INTRODUCTION

The CT-100B portable C-size VXIbus mainframe provides cost-effective test situations in a small
footprint. When using VMIP instruments such as DMMs, waveform generators, digitizers, etc.,
complete test scenarios can easily be configured.

SECTION 1

FIGURE 1-1 CT-100B SIX-SLOT CHASSIS

CT-100B Introduction 11

GENERAL DESCRIPTION

The CT-100B chassis is a portable, C-size, six-slot, VXIbus compatible chassis that conforms
fully to VXIbus Specification Revision 1.4. The chassis employs a multi-layer backplane to
ensure premium VXIbus and VMEbus performance and provides all power supplies required by
the VXIbus specification.

The CT-100B supports conventional existing rack designs through an optional rack mounting kit
(see Section 2). The six-slot design minimizes the use of precious rack space and is an
economical alternative to a larger chassis when fewer slots are required.

The CT-100B chassis contains six slots in the card cage, five of which are available for use by
VXIbus compatible instruments. The sixth slot in the card cage (slot 0) is typically dedicated to
the VXIbus Resource Manager.

The CT-100B is designed to operate at line frequencies between 47 Hz and 63 Hz and is factory
preset to operate at a nominal line voltage of 115 VAC. The chassis auto selects between a
nominal 115 VAC or 220 VAC line, requiring only the fuse be changed to operate at a nominal
220 VAC.

The rear panel provides a connector for 5 V STANDBY. Power supplied to this connector is
passed directly to the backplane line +5VSTDBY. This allows properly configured systems to
take advantage of an alternate power supply source, i.e., battery backup of memory or energizing
high stability reference oscillators.

VXI Technology, Inc.

BACKPLANE

PERFORMANCE

The backplane is a monolithic, multi-layer design, with automatic, solid state daisy-chain
jumpering for the interrupt acknowledge and VMEbus grant lines. This eliminates the need for
manual jumpering and provides improved reliability over mechanical jumper-less backplane
designs. Instrument modules can now be added or removed without concern for the backplane
configuration.

The CT-100B uses a pressurized airflow system. As air enters the mainframe from the rear, it is
pressurized below the cards and is then evenly distributed across all slots and along the total
length of each card slot, avoiding hot spots common in other designs. The air exhausts through
the top and away from the user. This cooling approach helps increase MTBF (Mean Time Before
Failure) figures and module performance.

High-quality power supplies are used in the CT-100B that are UL, CSA and TUV approved. The
power supplies are short-circuit, over-voltage, reverse-voltage and thermal-shutdown protected.
Auto-ranging power supplies are used to avoid any concern about the voltage source used. In
addition, all supply lines are monitored and displayed on the front panel to provide user feedback
of correct operation (see Figure 3-2).

12 CT-100B Introduction

www.vxitech.com

FLEXIBILITY

The CT-100B is designed to provide flexibility of use in bench-top and rack-mount applications,
as well as in portable environments. The outside cover is removable for easy access to the
VXIbus modules during bench-top development, troubleshooting or calibration. For rack-mount
applications, a rack-mount kit allows the CT-100B to mount flush or be recessed four inches. A
latched door is provided with the rack-mount kit, which can be user-modified to accept
connectors, switches or indicators. See Section 2 for rack-mount installation.

INSTALLATION

INTRODUCTION

When the CT-100B is unpacked from its shipping carton, the contents should include the
following items:

(1) CT-100B Six-Slot Chassis
(1) CT-100B Module User’s Manual (this manual)
(2) Replacement fuses, one 10 A slow blow, one 5 A slow blow
(1) Power cord

All components should be immediately inspected for damage upon receipt of the unit.

SECTION 2

LINE VOLTAGE SELECTION

The CT-100B provides auto-ranging power supplies, which automatically sense the line power
value and set themselves accordingly. Ensure that the fuse is correctly rated for the selected line
voltage (the CT-100B is factory configured with a 10 A/115 V fuse). The fuse is located in fuse­holder F1 on the rear panel of the chassis. The correct fuse ratings are:

See Figure 2-1 for the location of the line fuse.

CAUTION

Do not attempt to change the fuse with the line cord connected. Ensure that power is off
and that the unit is unplugged before changing the fuse.

BACKPLANE

The CT-100B has a jumper-less auto-configurable backplane using active-automatic daisy
chaining for the VME Interrupt acknowledge and bus grant daisy chain signal lines. This
eliminates the need to manually configure the backplane.

RACK MOUNT OPTION INSTALLATION

OVERVIEW

This section contains the procedures for installing a CT-100B chassis in a standard 19” relay rack.
The available rack mounting options are:

Option 52 – Rack Mount Ear Kit
Option 53 – Rack Mount Door Kit
Option 57 – 20” Slide Kit
Option 58 – 24” Slide Kit

The rack mount ear kit provides the basic hardware necessary to rack mount the CT-100B chassis.
Because the chassis is only 15” wide, standard rack support rails cannot provide mechanical
support to the chassis. If the equipment mounted below the CT-100B cannot provide mechanical
support to the chassis, either 20” or 24” slides will be required to support the chassis in the rack.
The rack mounting ears are designed to allow the chassis to be flush mounted in the rack or
recessed 4”.

The rack mount door kit provides the necessary hardware to install either a 1/8” thick aluminum
door or a 1/8” thick acrylic door in front of the rack mounted chassis. These options require that
the rack mount ear kit also be installed and configured for recessed mounting. The door may be
customer modified to hold connectors, controls, indicators and similar components.

The 20” and 24” slide kits provide the ability to easily remove the chassis from the rack for
servicing and provides mechanical support for the chassis when installed in the rack. The 20”
slide kit is used when the chassis is flush mounted in the rack. If the chassis is to be recess
mounted, then the 24” slides are required.

RACK MOUNT KIT INSTALLATION

The rack mount kit (Option 59) provides the basic hardware necessary to rack mount the
CT-100B chassis. With the chassis being only 15” wide, standard rack support rails cannot
provide mechanical support to the chassis. If the equipment mounted below the CT-100B cannot
provide mechanical support to the chassis, either 20” or 24” rack slides will be required to support
the chassis when installed into the rack. The rack mounting ears are designed to allow the chassis
to be flush mounted in the rack or recessed 4”.

ASSEMBLY PROCEDURE

1. Remove the four (4) black plastic feet from the bottom of the chassis.

2. Lay the chassis on a protected work surface on its long side with the voltage monitor LEDs of
the chassis facing front with the power switch toward the top.

3. Locate and remove four black plastic feet on the side of the chassis and four black plastic feet
on the bottom of the chassis. Retain the feet if restoring the chassis to its original portable use
is anticipated.

4. Find two threaded holes on each side of the chassis (the plastic feet were attached to two of
these holes) towards the front of the unit.

5. Line up the rack mount ears with the threaded holes selecting the flush or recessed position as
desired. Refer to the rack mount ear installation diagram for visual assistance.

6. Secure the rack ears using the supplied #8-32 hardware.

Before installing the chassis into an EIA switch rack, the chassis handle should be removed. This
can be done by doing the following:

1. Remove the four screws located near the handle.

2. Remove the two black decorative covers at each end of the carrying handle using the flat
blade screwdriver. Place a piece of paper under the screwdriver blade to prevent scratching
the chassis cover.

3. Remove the four Phillips screws holding the handle in place and then remove the handle
itself. Retain the carrying handle components if there may be some need to restore the
chassis to its original portable use in the future.

RACK SLIDE INSTALLATION (20” AND 24”)

The 20” and 24” slide hardware kits (Options 63 and 64, respectively) provide standard flanges to
mount the slides into standard EIA relay racks. It should be noted that the slide flanges in the
front should be installed behind the rack’s front panel mounting rails. This will allow the rack
mounting ears to sit flush with the front of the rack. It should also be noted that although the
hardware provided in this kit will provide all the necessary components to successfully install the
CT-100B into a rack, there are many variations in how EIA relay racks are designed and
additional adapter hardware may be required to install the chassis. Please refer to the relay rack
manufacture’s catalog for additional options.

This procedure provides instructions for installing the 20” or 24” slide kits. Note that the 20” and
24” slide kits are identical except for the length of the slide units. A 20” slide kit is used when the
chassis is flush mounted and a 24” slide kit is used when the chassis is recess mounted.
