Multiplexing Basics2-5The three-pole analog backplane of the Model 7001/7002mainframe is shown in Figure 2-5. Through this analog back-plane, the banks of a Model 7015 multiplexer card, installedin one slot, can be connected to the banks (or rows) of a com-patible card installed in another slot of the mainframe.Note that the Model 7002 also has backplane jumpers, whichcan be used to isolate cards into two groups of five.Figure 2-5Model 7001/7002 analog backplaneAnalogBackplaneCard 1 Card 2Model 7001/7002HLGRow 1 or Bank A HLGHLGRow 2 or Bank B HLGHLGRow 3 or Bank C HLGHLGRow 4 or Bank D HLGH = HighL = LowG = GuardRow = Matrix Card (7012)Bank = MUX Card (7015)2.2.2 Backplane jumpersThere are four pairs of backplane jumpers located on the re-lay card. With the jumpers installed, the banks of the multi-plexer card are connected to the analog backplane of theModel 7001/7002 allowing expansion with a second card in-stalled in the mainframe. With the jumpers removed (cut),the multiplexer card is isolated from another card installed inthe same mainframe.Artisan Technology Group - Quality Instrumentation ...
