SECTION 4 - PROGRAMMING GUIDE
MODULE ARCHITECTURE - X4 CONFIGURATIONS
Versions of the 40-562B with 4 Y connections are high density single or double pole switching matrices constructed
from 44x4 sub-matrix cards linked with an analog backplane. Depending upon the mechanical size, (BRIC2, 4,
8 or 12) between 2 and 18 sub-matrix cards can be fitted. Signal paths are made by operating the relays at the
crosspoints between X and Y lines allowing single X-Y connections, or X-X connections using a Y line as a path.
Y signals are routed between sub-matrix cards via the analog backplane, Isolation switches are included between
the Y bus and the backplane. The isolation switches disconnect unused Y signals from the backplane preserving
bandwidth and crosstalk performance. An example configuration for a 792x4 matrix using 18 sub-matrix cards is
shown in the diagram below.
