HOW TO CONFIGURE THE
1260-45 MATRIX MODULE
Introduction
The 1260-45 is a high-density matrix module containing four
4x16 matrices. Larger matrices may be configured via internal
jumpers or by using external cabling. This application note will
detail how to achieve this interconnection and give a practical
example.
Figure A-1
shows that J200 and J201 contain the rows
of the matrices and J202 and J203 contain the columns of the
matrices.
Configuration
The 1260-45 module is constructed from two printed circuit
boards mounted one on top of the other. (See
Figures A-1
and
A-2
for a block diagram of the module.) Modules may be
purchased from the factory with internal jumpers installed.
Following are the three basic configurations:
∗
1260-45A Quad 4x16 matrices (no
jumpers) (See
Figure A-4
)
∗
1260-45B Dual 4x32 matrices (rows
jumpered), J9, J10 (See
Figure A-5
)
∗
1260-45C Dual 8xl6 matrices (columns
jumpered), J7 J8 (See
Figure A-6
)
The flexibility of this module allows the user to reconfigure these
on-board jumpers. Additional flexibility is achieved because of
the pin-out of the front panel connectors. The matrices may also
be interconnected across boards via external cabling. A simple
ribbon cable across J200 and J2Ol connects the rows of group 0-
2, 1-3 in parallel.
