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:

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 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.
