Secondary Connection Page - Wireless Access Overview

IP Routing

The behavior of the wireless routing is largely dependent on the wired network interface. Although
the panel can be connected to two networks simultaneously it may only have one gateway. If the
wired network was successfully set up and a gateway was obtained; then the default route for all
network traffic will be via the wired network. In the event that the wired network was not
configured, then the default route for all network traffic will be via the wireless network. The wired
network connection always takes priority.
As an example:

Hot Swapping

Hot swapping is not an issue on these panels as the card is installed within the unit and cannot be
removed without first removing the housing.
In the case of DHCP, there must be a DHCP server accessible before the fields are populated.
If the SSID (Network Name) and WEP fields have not previously been configured, the
Secondary Connection page will not work until the panel is rebooted.
Ethernet Communication from the panel can be direct (using an Ethernet cable) or indirect (through
the NXA-WC80211B/CF AMX Wireless Card communicating to a Wireless Access Point (WAP)
such as the NXA-WAP200G). In determining the Ethernet method of communication, the panel
will always default first to the direct Ethernet communication. If no direct connection is detected,
the panel will first check to see if there is an installed wireless interface card and then communicate
to the WAP using the Wireless Settings assigned within the Secondary Connection page. The WAP

Imagine a panel connected to two networks A & B. A is the wired network and B is the
wireless network. If the Master controller is on either of these networks then it will be
reached. However if the Master controller is on a different network, C, then determining
which network interface (wired or wireless) that will be used is dependent on the
gateway.
