The access control unit connects to the Net2 software running on the PC using Paxton Net2Air proprietary wireless
technology. A Net2Air bridge enables communication from the Net2 software to the Paxton wireless products.
Radio signals do not always behave as you might expect. For example, a cell phone that displays a full signal on
one part of the site will lose signal completely only a few feet away. These problems can be addressed by using the
Net2 site surveyor kit (690-200-US)

Data transfer with wireless technology requires far more control and error checking than with a hard wired data
line connection. Net2 classic runs with a server that originates and controls all the communications on the data
line. This would not be efficient in a wireless environment.
We therefore give the Nano controller the active role. Each Nano is always active and transmits data bursts
(including a regular Heartbeat) every few seconds. The Net2 server then acts upon these requests for service.
The PC requires at least one Net2Air bridge to communicate with a Nano. This can be a local Net2Air USB bridge
(only one per system) and/or multiple Net2Air Ethernet bridge units connected to the PC via a TCP/IP connection.

There is NO Net2 nano detection function.
It is recognised that there could be security issues if the wireless
units were detectable from outside the site. During installation, a Nano unit binds with a Net2Air bridge which will
then only talk to registered units. The Server configuration utility also has an ' Enable commissioning' mode which
can be turned off to inhibit Nano units being added.
Net2Air wireless control units are fully compatible with the hard wired Net2 range but there are several important
differences that need to be understood before installing wireless equipment. The most important of these is the
location of the control units and their bridge components.
These principles are therefore explained first before we move on to the control unit itself.
The reader's default indication has all the LED's on. Access granted is denoted with a single flashing Green LED.
Access Denied is a single flashing Red LED.
A Net2 nano ACU or a Hands free interface cannot be installed in a Metal cabinet as this would block the RF signal
used for the Net2Air wireless technology.
