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:
 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.
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.
Ethernet Communication from the panel can be direct (using an Ethernet cable) or indirect (through the
NXA-WC80211GCF AMX Wireless Card communicating to a Wireless Access Point (WAP) such as the
NXA-WAP200G). The Wireless Access Point communication parameters must match those of the
installed wireless CF card inside the panel.
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 Wireless Settings page. The WAP communication parameters must match those of the pre-
installed wireless interface card installed within the panel. These touch panels allow users to connect to a
wireless network through their use of the optional AMX 802.11g Wi-Fi CF card. The WAP
communication parameters must match those of the pre-installed wireless interface card installed within
the panel. This internal card transmits data wirelessly using the 802.11x signals at 2.4 GHz.
For a more detailed explanation of the new security and encryption technology, refer to the section of the
document entitled Appendix B - Wireless Technology section on page 189.
Configuring a Wireless Connection
When working with a wireless card, the first step is to configure wireless communication parameters
within the Wireless Settings page. This page only configures the card to communicate to a target WAP
(such as the NXA-WAP200G), it is still necessary to tell the panel which Master it should be
communicating with. This "pointing to a Master" is done via the System Settings page where you
configure the IP Address, System Number and Username/Password information assigned to the target
Master.
If the SSID (Network Name) and WEP fields have not previously been configured, the
Wireless Settings page will not work until the panel is rebooted.
