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.

Command Summary
M - Matrix - Select a specified Matrix.
L - Latch - a specified Module and Switch in a Matrix.
U - Unlatch - a specified Module and Switch in a Matrix.
X - Multiplex - Latches a specified Switch and Clears all
others.
C - Clear - Unlatches every switch in the Matrix.
S - Status - The Status of the Matrix is returned to the
Controller.
F - Front Panel - Allows the disabling of front panel con-
trols.
P - Program - Allows the operator to set up Matrix vari-
ables such as size and configuration and stores them in
nonvolatile memory.
Typical Commands Are:
Command Function
L, n1, n2, n3 Latch Selected Switch
U, n1, n2, n3 Unlatched Selected Switch
X, n1, n2, n3 Mux Selected Switch
n1=Matrix, n2=Module, n3=Switch
C Clear entire system
C, n1 Clear matrix - n1=Matrix
S Status of Entire System
S, n1 Status of Matrix - n1=Matrix
S, n1, n2, n3 Return Switch Status
n1=Matrix, n2=Module, n3=Switch
F, n1, n2, Front Panel Lock out
n1=0 disable, n1=1 enable, n2=access
P, n1, n2, n3 Program setup
n1=Parameter, n2=value, n3=access
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 Baud and is stored in nonvolatile memory.
The Command structure is the same as the IEEE488 Mod-
ule and has the following additional command features:
E - Echo - Echoes all received characters back to the source.
V - Verbose - Enables the matrix to return text strings in re-
sponse to Commands, including error statements.
H - Help - This is a summary of all the Commands.
RS232 Specific Commands
Command Function
B, n1, n2 Baud Rate - n1=rate, n2=access
E, n1, n2 Echo - n1=0 off, n1=1 on, n2=access
V, n1, n2 Verbose - n1=0 off, n1=1 on, n2=access
CM-6 LAN INTERFACE
This is a 10Base-T Ethernet LAN to RS232 interface module
which accepts data in TCP/IP format from the Local Area Net-
work and outputs it in RS232 format to the MESA.
When used with the RS232 Serial Module, it can control the
MESA Control Units with the same Command Structure de-
tailed in the CM-5.
This interface can be used to access the MESA Control Unit
from remote locations and from several users via the Local Area
Network using raw TCP/IP, or Telnet. Setup of the interface is
through an external RS232 connection which allows you to
specify TCP/IP address, host name, gateways and many other
network parameters.
The LAN interface manual is available via e-mail in PDF format
by contacting CYTEC's sales staff.
Two types of Manual Control are offered: the MC-2 and the
VMCS.
