The RF channel being used for connection to the WAP (read -only).

• This is determined through the WAP.

Displays the current quality of the link (as descriptive colored text) from the wireless NIC to the Wireless Access Point in real time.

•The bargraph has been replaced with a descriptions: None, Poor, Fair, Good, Very Good, and Excellent. Green color text indicates better communication quality.

•It reports the quality of the signal over the air (direct sequence spread spectrum). Even when the link quality is at its lowest you still have a connection and with it the ability to transmit and receive data, even if at much lower speeds.

Note: Both Link Quality and Signal Strength are applicable to the RF connection only. It is quite possible to have an RF signal to a Wireless Access Point but be unable to communicate with it because of either incorrect IP or encryption settings.

SNR (Signal Noise Ratio) is a measure of the relative strength of a wireless RF connection. This indicator displays a description of the signal strength from the Wireless Access Point connection.

•The bargraph has been replaced with a descriptions: None, Poor, Fair, Good, Very Good, and Excellent. Green color text indicates better signal strength.

•Given this value and the link quality above, a user can determine the noise level component of SNR.

Ex: If the signal strength is high but the link quality is low then the cause of the link degradation is noise. However, if the signal strength is low and the link quality is low the cause would simply be signal strength.

The data rate (in Mbps) at which the panel is currently communicating with a target WAP at (dynamic).

•As you move closer to the target WAP (and both the signal strength/ quality), the data rate increases and as the quality degrades this rate decreases.

•Data rates for 802.11b communication are: 1, 2, 5.5, and 11 Mbps.

•Ex: 802.11b has a max data rate is 11 Mbps.

System Connection Page

The System Connection page (FIG. 94) sets the Secondary DNS Address information with its corresponding IP communication parameters, NetLinx Master communication settings, and reads the device number assigned to the Modero panel.
