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.

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.
