System Settings Page
The System Settings page (FIG. 101) 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.
The elements of the System Settings page are described in the table below:
Wireless Settings Page Elements (Cont.)
Wireless Settings (Cont.):
Link Quality 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.
Signal Strength 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.
Data Rate 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 802.11g communication are: 1, 2, 5.5, 11, and 54 Mbps.
• Ex: 802.11g has a max data rate is 54 Mbps.
