1.2 Radius Server Components
1.2.1 Radius Server
The Radius server is a Windows XP embedded server typically connected to 
the local area network (LAN) to allow existing users to view and administer the 
Radius system from their workstations.
The Radius server includes four serial ports, one Ethernet port, six USB ports 
and four analog telephone jacks.
1.2.2 Network Coordinator
The network coordinator manages signals between the wireless end devices 
in the Radius system and the Radius server. 
1.2.3 High Power Repeater
The high power repeater intelligently amplifies transmissions from any 
Inovonics EchoStream end device, while ignoring background noise. Virtually 
any number of repeaters can be added to a system, scaling the system size as 
needed.
• Radius can also use the high power repeater network to provide the
approximate location of wireless end devices sending alert signals.
1.2.4 Wireless End Devices
The Radius system can incorporate any Inovonics wireless end device, 
including:
1.2.4.1 Pendant Transmitters
Inovonics wireless pendant transmitters offer virtually limitless opportunities for 
panic/duress, life safety, and many custom applications.
