MATRIX EXPANSION SYSTEMS
The following Control Modules are available:
CM-1 TTL CONTROL
This module utilizes TTL / CMOS signals and requires 13 input
bits and 1 output bit. Typically used when high speed commu-
nication is necessary. May be driven from a CYTEC PC-IO
computer card.
CM-5 IEEE488/RS232
This Module has both the IEEE488 Bus and RS232 Serial Con-
trol . See page MESA-3 for details.
IF-6 LAN INTERFACE
This module interfaces between the Local Area Network and
the RS232 Control Modules using TCP/IP commands.

System
The MESA Series Controllers make it possible to control multiple CYTEC switch chassis from one Con-
trol Module. It can be utilized to build large Matrix or Multiplexer configurations or simply run multiple
different types of chassis. The MESA also saves money on large systems since each chassis does not
need a separate control module and often do not need power supplies.
These Chassis can be any combination of different types of Expansion Chassis from CYTEC's complete
line of switching products.

is a software interface which enables the remote opera-
tor to view the Status of the Matrix and to Control Switch Selec-
tion using a full Graphical User Interface.
There are three basic Control Units: the MESA 4, the MESA
16 and the MESA 32.
MESA 4 CONTROL UNIT
This Control Unit has 4 Output Ports to control 4 Expansion
Chassis from one Control Module. The MESA 4 is 3.5" high.
MESA 16 CONTROL UNIT
This Control Unit has 16 Output Ports to control 16 Expansion
Chassis from one Control Module. The MESA 16 is 3.5" high.
MESA 32 CONTROL UNIT
This Control Unit has 32 Output Ports to control 32 Expansion
Chassis from one Control Module. The MESA 32 is 7" high.
Drivers available for National Instrument's LabView or
LabWindows programming platforms or Agilent VEE pro-
gramming platform. MESA CONTROL UNITS
There are three basic models of the MESA Control Unit: the MESA 4, the MESA 16 and the MESA 32. They
contain Power Supplies and an Expansion Motherboard. The Control Module and Expansion Interface Mod-
ules plug into the Motherboard so that one Control Module can control up to 32 Expansion Chassis.
The System shown in Fig. 1 has a MESA 16 Control Unit and four Expansion Chassis arranged and addressed
as a 32x16 Matrix. This leaves 12 additional ports to expand the system by adding twelve Expansion Chassis.
MESA 4 CONTROL UNIT
MESA 16 CONTROL UNIT
This is a 19" rack mountable chassis, 3.5" high and 12" deep
which will accept any of the Control Interfaces and 4 Expansion
Ports to control 4 Expansion Chassis. The Power Supply has
sufficient logic power to drive all 4 Expansion Chassis and re-
lay power to energize up to 200 relays at one time.
This is a 19" rack mountable chassis, 3.5" high and 12" deep
which will accept any of the Control Interfaces and 16 Expan-
sion Ports to control up to 16 Expansion Chassis as shown in
Fig. 1. The Power Supply has sufficient logic power to drive all
16 Expansion Chassis and relay power to energize up to 200
relays at one time.
MESA 32 CONTROL UNIT
This is a 19" rack mountable chassis, 7" high and 15" deep
which will accept any of the Control Interfaces and 32 Expan-
sion Ports to control up to 32 Expansion Chassis. The Power
Supply has sufficient logic power to drive all 32 Expansion Chas-
sis and relay power to energize up to 200 relays at one time.
RELAY POWER REQUIREMENTS
The 12 volt relay power supplied with the MESA Control Units is sufficient for most Matrix or Multiplex operations.
However, some applications require a larger number of switches to be closed. For these cases, two options are offered:
Auxiliary Power Supply or Powered Expansion Chassis.
POWERED EXPANSION CHASSIS
This is a separate 19" rack mounting chassis, 3.5" high and 12"
deep with +5 volt logic power for up to 32 Expansion Chassis
and relay power to energize up to 500 relays.
MESA-2
AUX-1 POWER SUPPLY
Where the power requirement in individual Expansion Chassis
is very high, each Expansion Chassis can be supplied with its
own relay power supply capable of energizing up to 200 relays
per Expansion Chassis.
CONTROL MODULES
The Control Modules are plug compatible with all the MESA control Units and have the same command
structures for Control and Switch Selections.
The commands for Mode Control are Latch, Unlatch, Matrix Mode, Mux Mode, Clear or Status Request.
The standard commands for selecting a Switchpoint are to select Matrix, Module and Switch.
These modules are available to control the MESA Units from TTL, IEEE488 BUS, RS232 Serial Port or 10Base-
T Ethernet LAN.
They include standard or special firmware for different configurations such as:
In a Matrix configuration, the command can be Input # and Output # selection for the crosspoint.
In a Multiplexer application, the command can be Channel # selection for one switch selection only.

MESA TO EXPANSION CHASSIS DISTANCE
Individual Expansion Chassis are normally supplied with 6 foot cables. The expansion chassis can be provided with ribbon
cables up to a length of 20 feet on request. Expansion chassis may be located up to 200 feet from the MESA if a better type
of cable is used. To discuss these options please contact CYTEC's sales staff. CM-5 IEEE488/RS232
This Module combines both the IEEE488 Talk Listen Con-
trol and the RS232 Serial Controls.
The Talk and Listen addresses are the same and are set by
a 5 position DIP Switch. In the Listen Mode, the Matrix re-
sponds to specific commands. The Talk Mode is used to
return the Status of the Matrix.
IEEE488 TALK/LISTEN (GPIB)
RAM OPTION
This option is available in the CM-5 and CM-6. Switch selec-
tions are stored in the battery backup RAM (Random Access
Memory) with the following benefits:
At Power-On, the switches can be latched to a preset default
switch configuration.
In cases of momentary power loss, the matrix will be reset to
the last selected configuration before loss of power.
Multiple configurations can be stored and recalled as required
up to a maximum of 1,000 switch selections.

MANUAL CONTROL OPTIONS
MC-2 KEYBOARD CONTROL
This Manual Control has a keyboard and LCD backlit display
mounted on the front panel.
The LCD display has two lines of 16 alphanumeric characters.
The top line displays the matrix commands and switch selec-
tion.
The bottom line displays the Status of a selected switch and
Error messages.
This module can only be used with the CM-5 and CM-6 Con-
trols.
This enables the remote operator to view the Status of the Ma-
trix using a full Graphical User Interface.
The matrix configuration is displayed and crosspoints are se-
lected by a point and click operation. Each selected crosspoint
is prominently shown on the display.
Custom labeling of the Inputs and Outputs can be programmed.
One optional mode of operation prevents selection of switches
that would interconnect two Inputs or two Outputs.
SOFTWARE
Drivers and/or sample programs are available with the
most commonly available application programming lan-
guages.
RS232 SERIAL
The module can be configured as either a Data Terminal
Equipment (DTE) or Data Communications Equipment
(DCE). The Baud Rate is software programmable from 110
to 19,200
