CT-100C Introduction 9
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

VXI Technology, Inc.
10 CT-100C Introduction
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
(see Section 1). 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-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
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.
PERFORMANCE
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).

www.vxitech.com
CT-100C Introduction 11
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.

SECTION 2
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 CT-100C
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.

20 CT-100C Installation
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 Figure 2-1 for power supply removal instructions). The power interface board
will be located inside the mainframe at the top right. Doing this will disable the front panel power
switch. Pins 5 and 18 can now be used to remotely control the powering of the chassis. The circuit
is diagramed below:
