SECTION 1

INTRODUCTION

INTRODUCTION

The CT-100C 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.

FIGURE 1-1: CT-100C SIX SLOT CHASSIS

CT-100C Introduction 11

GENERAL DESCRIPTION

The CT-100C chassis is a portable, C-size, six-slot, VXIbus compatible chassis that conforms
fully to VXIbus Specification Revision 2.0. 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-100C supports conventional existing rack designs through an optional rackmounting kit

Section 1). The six-slot design minimizes the use of precious rack space and is an economical

(see
alternative to a larger chassis when fewer slots are required.

The CT-100C 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-100C is designed to operate at line frequencies between 47 Hz and 63 Hz and utilizes a
power supply that automatically adjusts to accept line voltages between 100 V ac and 240 V ac.
There is an internal fuse that provides protection against catastrophic failures and is designed to
operate within the valid input range.

The rear panel provides a connector for 5V STANDBY. Power supplied to this connector is
passed directly to the backplane line +5V STDBY. 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.

BACKPLANE

VXI Technology, Inc.

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-100C 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-100C 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 1-4).

12 CT-100C Introduction

www.vxitech.com

FLEXIBILITY

The CT-100C is designed to provide flexibility of use in bench-top and rackmount 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 rackmount
applications, a rackmount kit allows the CT-100C to mount flush or be recessed four inches. A
latched door is provided with the rackmount kit, which can be user-modified to accept connectors,
switches, or indicators. See

Section 1 for rackmount installation.

INSTALLATION

INTRODUCTION

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

(1) CT-100C Six-Slot Chassis
(1) CT-100C Module User’s Manual (this manual)
(1) Power cord

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

BACKPLANE

The CT-100C mainframe 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 and insures that these signals are
properly configured at all times.

The power cord is the only way to disconnect the CT-100C mainframe from ac power.

Therefore, the power cord must be accessible to the operator at all times. When the CT­100C mainframe is mounted in a system rack, the power cord need not be accessible since
the rack must have its own disconnect device.

Le cordon de secteur est la seule manière de démonter l’unité centrale de CT-100C du

courant alternatif Par conséquent, le cordon de secteur doit être accessible à l’opérateur à
tout moment. Quand l’unité centrale de CT-100C est montée dans un support de système, le
cordon de secteur n’a pas besoin d’être accessible puisque le support doit avoir son propre
dispositif de débranchement.

CT-100C Installation 21

REMOTE POWER-ON OPTION

If the CT-100C mainframe is to be installed in a remote location, it is possible to apply and
remove power from the unit via the remote power pins located on connector J201. To utilize the
remote power feature, set the front panel switch to the standby position. Remove the power cord,
then remove the power supply from the chassis and place the jumper on the power interface board
to the 2 – 3 position (see
board will be located inside the mainframe at the top right. Doing this will disable the fron t panel
power switch. Pins 5 and 18 can now be used to remotely control the powering of the chassis. The
circuit is diagramed below:

FAN SPEED SWITCH

A fan speed selector switch is located at the rear of the CT-100C chassis. To set the fans to
operate at HIGH speed, move the switch at the rear of the chassis to the left. At HIGH speed, the
chassis is provided maximum cooling to the instruments.

The fans will operate in the LOW speed mode when the fan speed switch is toggled to the right.
The low speed mode provides for quieter operation, but d ecreases the cooling capability of the

RACKMOUNT OPTION INSTALLATION

OVERVIEW

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

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

The rackmount ear kit provides the basic hardware necessary to rackmount the CT-100C 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-100C cannot provide mechanical
support to the chassis, either 20” or 24” slides will be required to support the chassis in the rack.
The rackmounting ears are designed to allow the chassis to be flush mounted in the rack or
recessed 4”.

The rackmount 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 rackmounted chassis. These options require that
the rackmount 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.

RACKMOUNT KIT INSTALLATION

The rackmount kit (Option 59) provides the basic hardware necessary to rack mount the CT-100C
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-100C 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 rackmounting 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 restorin g the ch assis to its orig inal po rtable 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 rackmount ears with the threaded holes selecting the flush or recessed position as
desired. Refer to the rackmount ear

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 rackmounting
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-100C
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 th e length of the slide units. A 2 0” slide kit is used when the
chassis is flush mounted and a 24” slide kit is used when the chassis is recess mounted.

INSTALLATION OF VXI MODULES

OVERVIEW

After the successful installation of rackmount accessories, the chassis is ready for installation of
the VXIbus base units (i.e. an SMP1100, SMP1200, etc.). It is recommended that the instruments
be installed after rackmount accessories have been installed to avoid any unnecessary physical
strains that may be incurred during the installation of the accessories. Whether single- or double­wide, the process of installation is simple.

Required Tools

1. Slotted screw driver

Installation Procedure

Install C-size modules directly into the mainframe as follows:

1. To prevent damage to the module, insure the mainframe is powered off.

2. Insert the module into the mainframe by aligning it with both the upper and lower card guide
of the desired slot. The card guide for the module is the right, longer guide-pair of each guide
set.

3. Gently push the module into the slot until it seats into the backplane connectors. The front
panel of the module should be flush with mainframe.

4. Tighten the mounting screws at the top and bottom of the module.
