8.2 Principle of the teleCARE IP with Wireless Functionality
The system is configured using the teleCARE IP System Manager - NISM2. The wireless server is a Unite
application on the NISM2 serving as the central controller for all wireless devices in the teleCARE IP
system with wireless functionality.
The wireless server has similar functions to those found in the teleCARE IP room controller, such as
event handling, assignment handling and linking, with additional functions such as signal strength
comparison. The main difference between the wireless server and the teleCARE IP room controller is
that the wireless server controls all wireless devices in the system, whereas each room controller is
responsible for only the devices which are hard-wired to it.
The NIRC3 room controller requires the piggy-back mounted NIRX transceiver module to give it
wireless compatibility. When combined with the NIRX the room controller also serves as a base station
and portal for the wireless devices.
The NIFX fixed transceiver has a piggy-back mounted NIRX transceiver, whereas the NITX mobile
transceiver has its’ own internal transceiver.
