Mixed card type example
Mainframe multiplexer expansion
Twelve- or 60-card multiplexer systems are possible by
connecting six Model 7001 or six Model 7002 mainframes,
respectively. Each Model 7021 added to the system provides
30 additional inputs. The limits on the number of cards in the
Model 7001/7002 switch system are due to triggering.
Section 4 explains how to connect a test system using two
mainframes.
