Configuring a Wireless Connection, Hot Swapping

Configuring Communication

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.

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.

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.
