Monitor Board
The Monitor board integrates the analog circuitry and interface circuitry for patient parameters,
a digital processing section as well as user interface controls, audio control, and power circuitry
for the entire system and charging circuitry for the battery. The Propaq M system relies on a
centralized dual processor engine for its computing needs. The Main Processor (MP) serves as
the primary user interface engine and provides connectivity needs, while the Patient Processor
(PP) controls the patient monitoring function. An additional power controller micro-controller
(PC) controls the power sequencing, and battery/charger interface.
