For testing multi-channel systems, a Multiplexer can help to simplify cabling and routing. The KLIPPEL Multiplexer hardware can be directly controlled by the QC SYSTEM. For R&D and all other applications, the routing can be controlled using dB-Lab software or by a USB or parallel port interface software, provided by KLIPPEL. This software can be controlled by the command line of automated applications. KLIPPEL offers very flexible Multiplexer 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. Several 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.
