Revision C
Equipment Overview: Theory of Operation
An installation can have more than one receiver system. Each receiver system can
have up to 16 receivers. Each receiver can be associated with (and receive data
from) one ApexPro transmitter.
Refer to the ApexPro Receiver System documentation for further details.
The antenna system transfers information from the transmitter to the receiver system
for demodulation and waveform processing. Additionally, the antenna system
increases ApexPro reception range, allowing patients wearing transmitters to move
over an expanded area. As transmitters move around the facility, reception can
switch from one antenna to another as required to maintain RF signal coverage.
The antenna system includes the receiver antenna and all associated components up
to, but not including, the receiver system. There are two versions of the antenna
system: one for U.S. applications (560–614MHz) and one for international
applications (420–474MHz).
Refer to the ApexPro Antenna System site survey and installation manual for further
details.
The transmitter connects to the patient and transmits patient telemetry data to the
antenna system (which in turn, sends that data to the receiver system). The
transmitter acquires patient data, converts it to digital format, and serially broadcasts
the data along with pace, additional parameters (from devices attached to the serial
ports), and status in an RF signal.
