Specifications

All CXAR Chassis are available as Expansion Chassis for use
with a MESA Control Chassis. This design allows conguration
of large or complex systems with one point of control. Using
a Mesa Controller and multiple Expansion Chassis has the fol-
lowing advantages:
Cost Savings
Expansion chassis do not need power supplies or their own
Control Modules or Manual Controls, which adds up to cost
savings that pay for the Mesa on any system requiring three or
more expansion chassis.
Single Point of Control
You can control up to 32 CXAR chassis, or combinations of dif-
ferent chassis, from a single Mesa Control. This allows control
of up to 32 chassis from a single GPIB address, RS232 Port or
LAN IP address.
Remote Location of Multiple Chassis
Expansion Chassis can be located up to 125' from the Mesa,
so the switching chassis can be located where needed and still
not require a separate control.
Complex Test Systems
Since any Cytec chassis may be controlled from the Mesa, you
can build complicated systems switching a number of different
signal types using different Cytec products for each signal type.

LED INDICATORS / STATUS FEEDBACK
All CXAR Mainframe and Expansion Chassis have LED displays
that show state of every relay. These LED indicators are visible
on the front panel and correspond to the programmatic address
for each relay.
The LEDs provide an invaluable aid for program debugging and
troubleshooting. They allow you to verify switch point staus
instantly simply by watching the system's front panel.
CXAR/16 and CXAR/32 LED Indicators
On these systems the LEDs are built into the front panel of the
chassis and are included in the chassis prices.
CXAR/64 and CXAR/128 LED Indicators -- CL8 Modules
On these systems the LEDs are provided by a CL8 Display /
Driver Modules which must be purchased separately. Each
CL8 module provides eight relay drives and LEDs so they are
not optional, and one CL8 is required for every eight switch
points. The display / driver is also sold separatly because some
customers use them to drive external relays, or they buy sets of
different switch modules for different applications and separate
CL8's reduce the total price.
Cytec can easily customize your chassis to t specic needs
with little or no NRE (Non Recurring Engineering) charges. The
following examples are only some of the options available. If
you don't see what you need feel free to ask us if it can be done.
Our engineers will work with you to provide a tailored solution
for your specic application.
Labeling
Cytec's laser etch labeling system allows rapid custom labeling
of front or rear panels. Silk screening options or custom poly
carbonite overlays are also available for OEM systems.
Conguration
Cytec can precongure your system according to your exact
needs. Some examples are listed below:
• Build large multiplexers using bus bars or interconnecting
tree switches in series.
• Build large group switches with parallel drive wiring.
• Custom congured modules.
• Customized connectors, false rear panels or patch panels.

Chassis Dimensions or Mounting Options
We can build chassis with different dimensions or mounting
options, including reverse mounting the chassis to get the con-
nector out of the front, add connectors to the front panel or ush
mount the chassis for tight rack enclosures.
Custom components
Need a system with non-Cytec components added to get the
exact performance you need? Just let us know what you want
to accomplish. We can add splitters, amps, couplers and other
RF components to give you exactly what you need.
