• Refer to the Wireless Security Page section on page 94 for details. EAP-FAST This button opens the EAP-FAST Settings page (FIG. 81 on page 102). “EAP-FAST” security is designed for wireless environments where security and ease of setup are equally desirable. • Refer to the Wireless Security Page section on page 94 for details. Site Survey: The Site Survey tool allows you to detect and view detailed information on all WAPs within the panel’s communication area. Using this tool, you can select a WAP to connect to. • Refer to the Using the Site Survey tool section on page 46 for information on using this tool. RF Link Info: SSID Channel These options set communication values for the wireless interface card: Displays the currently used SSID of the target WAP. The RF channel being used for connection to the WAP (read -only). 10" Modero Widescreen Touch Panels Firmware Pages and Descriptions Wireless Settings Page (Cont.) RF Link Info (Cont.): Link Quality Signal Strength Displays the quality of the link from the wireless NIC to the Wireless Access Point (direct sequence spread spectrum) in real time (None, Poor, Fair, Good, Very Good, and Excellent). • Even when link quality is at its lowest you still have a connection, and the ability to transmit and receive data, even if at lower speeds. Note: “Link Quality” and “Signal Strength” are applicable to RF connections only. It is possible to have an RF signal to a WAP, but be unable to communicate with it because of either incorrect IP or encryption settings. This indicator displays a description of the signal strength from the Wireless Access Point connection in real time (None, Poor, Fair, Good, Very Good, and Excellent). SNR (Signal Noise Ratio) is a measure of the relative strength of a wireless RF connection. Given this value and the link quality above, you can determine the noise level component of the SNR. For example, if signal strength is high but the link quality is low, then the cause of the link degradation is noise. However, if signal strength is low and link quality is low the cause would simply be signal Data Rate strength. The data rate (in Mbps) at which the panel is currently communicating with the target WAP. Note: Data rates for 802.11b communication are: 1, 2, 5.5, and 11 Mbps. Secondary Connection Page The Secondary Connection page sets the communication information for an installed wireless interface card. The NXD-CV5 Touch panel is not enabled for wireless communication and therefore, this page is not user-editable. Wireless Security Page The options on the Wireless Security page allow you to select from the wireless security methods supported by the NXA-WC80211GCF Wi-Fi card. These security methods incorporate WPA, WPA2, and EAP technology (some of which require the upload of unique certificate files to a target panel). Refer to the Appendix B - Wireless Technology section on page 205 for more further information. Some encryption and security features may/may not be supported depending on the type of wireless card being used: Wireless Security Support 802.11g Wi-Fi CF card: • Open (Clear Text) • Static WEP (64-bit and 128-bit key lengths) • WPA-PSK • EAP security (with and without certificates) • WAP SIte Survey Refer to the Configuring a Wireless Network Access section on page 45 for more information on configuring the panel for wireless network access using the various security options. 10" Modero Widescreen Touch Panels Firmware Pages and Descriptions 802.11g wireless card Wireless Security pages (each Wi Fi card supports different security features) Open (Clear Text) Settings Press the Open (Clear Text) button to open the Open (Clear Text) Settings page (FIG. 76). FIG. 76 Wireless Settings page - Open (Clear Text) Settings 10" Modero Widescreen Touch Panels Firmware Pages and Descriptions Open security does not utilize any encryption methodology, but requires an SSID (alpha-numeric) entry. This entry must match the Network Name (SSID) entry of the target WAP so the panel knows what device it is using to communicate with the network. Open (Clear Text) Settings SSID (Service Set Identifier): Opens an on-screen keyboard to enter the SSID name used on the target WAP. The SSID is a unique name used by the WAP, and is assigned to all panels on that network. An SSID is required by the WAP before the panel is permitted to join the network. • The SSID is case sensitive and must not exceed 32 characters. • Make sure this setting is the same for all points in your wireless network. • NXA-WAP200Gs use AMX as their default SSID. • If this field is left blank, the panel will attempt to connect to the first available WAP. Save/Cancel: • Save - store the new security information, apply changes, and return to the previous page. • Cancel - discard changes and return to the previous page. ..
