Multiplexing Basics2-9Mixing card typesDifferent types of cards can be used together to create someunique switching systems. For example, you could have aModel 7015 multiplexer card installed in one slot and a Mod-el 7012 matrix card installed in another slot.Figure 2-12 shows one possible switching system using amatrix card and a multiplexer card. The backplane jumpersfor both the matrix and multiplexer cards must be installed.This arrangement allows matrix rows to be connected toFigure 2-11Multiplexer input expansion example1 10Bank BBank CBank DBank A70151 101 101 107001/7002AnalogBackplaneCard 1Quad 1x10 Multiplexers70151 101 101 101 10Card 2BackplaneJumpersinstalledQuad 1x10 MultiplexersQuad 1x20 Multiplexermultiplexer banks. On the multiplexer card, the bank-to-bank jumpers must be removed to maintain isolation be-tween matrix rows. See the instruction manual for the Model7012 for complete information on the matrix card.2.4.2 Mainframe multiplexer expansionMultiplexer systems using up to 12 or 60 multiplexer cardsare possible by using six Model 7001 or 7002 mainframes to-gether. Each Model 7015 added to the system provides 40additional inputs. Paragraph 3.4.3 explains how to connect atest system using two mainframes.Artisan Technology Group - Quality Instrumentation ...
