teleCARE IP
9.2 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.
