System Operation
Bluetooth Technology
Bluetooth technology allows wireless connections between electronic
communications and computing devices. The technology is based on a radio
link that offers fast and reliable data transmissions. Bluetooth technology uses
a license-free, globally available frequency range in the ISM band—intended to
ensure communication compatibility worldwide.
Nonin's use of Bluetooth wireless technology allows information to be
transmitted through a Bluetooth radio to a compatible Bluetooth-enabled
device. Nonin's wireless system removes the need for a physical connection
from the H500 monitor to a remote monitor location, giving increased ability to
move the monitor freely. Nonin's H500 monitor uses an automatically switchable
class I/class II Bluetooth radio with a maximum range of about 60 meters
(196 feet) (spherical radius).
The Model H500 features point-to-point communications, allowing one master
device (the remote monitor) to be paired to one slave device (the H500 monitor).
Once connected, the H500 monitor will not connect with any other Bluetooth-
enabled device.
Bluetooth Security
The Bluetooth radio contained in the H500 monitor is compliant to version 4.2 if
the Bluetooth Specification. It supports the Serial Port Protocol (SPP) with
security mode 2 (service level enforced). The supported encryption key size is up
to 128 bits and encryption is enforced on all outgoing and incoming data
channels. While the display is in a Bluetooth connection, it will be unavailable for
other connections. The H500 system only supports a custom bonded Bluetooth
pairing which prevents inappropriate connections to the system.
