94 Technical Overview Welch Allyn Propaq Encore Vital Signs Monitor
System Description
The Encore monitor can be configured as a standalone monitor or with one of two
optional housings containing different monitoring and printer options.
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 Encore monitoring system housings.
The Encore 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.
The Encore system block diagram is shown on page 99.
The Encore electronics consist of the power system, monitoring electronics, and the cuff
pneumatics.
