The KLIPPEL Multiplexer is a very flexible signal switching hardware with up to 8 channels. Different 

routing modes are available to use the Multiplexer for selecting one or more input channels from 8 

resources or distribute one or two sources to up to 8 receivers. Different hardware versions with 

different connectors and electrical parameters are available. Different control ports offer the flexible 

usage in a lot of applications. The Multiplexer can be controlled manually and by software. The Mul-

tiplexer can directly be controlled by Klippel hard / software in the QC framework. For R&D and all 

other applications the routing can be controlled with a Klippel provided USB or parallel port interface 

software. This software can also be controlled from the command line for automated applications.
