Setup

vPad-A1 is a modular system having a

Base

and one, two or three additional modules which provide patient

simulation or monitor testing. This chapter describes the modules and their connector interfaces, and
provides instructions for assembly and setup of the system.

3.1 Modules and Interfaces

The vPad-A1

Base

module (

Figure 1

) is comprised of a 5"

Android

Tablet

and its cradle. The cradle incorporates a

rechargeable battery which provides power to itself and to
other modules of the system, as well as a communication
hub to facilitate control of the test/simulation modules. The

Tablet

also has a battery, which can be recharged through

the USB connection to the cradle.
