System description
The Propaq CS monitor can be configured as a stand-alone monitor or with one of two
optional housings containing different monitoring and printer options. The figures on the
following pages illustrate the possible housing configurations.
The main functional modules (e.g. Analog Board, Recharger Board, Printer, SCP Board,
etc.) reside in the housings. The figures on the following pages illustrate the location of
the main functional modules in the Propaq CS monitoring system housings.
The monitor electronics reside on three circuit boards within the monitor housing (front
and rear chassis). Additional circuitry for the printer and optional monitoring parameters
reside on additional circuit boards housed in the expansion modules.
