VG-Series Modero Touch Panels
Refer to both the Wireless Settings Page - Wireless Access Overview section on page 101 and
Configuring a Wireless Connection section on page 102 for more detailed information of setting up the
Modero panel for wireless network access.
Wireless Settings Page Elements (Cont.)
Wireless Settings (Cont.):
Channel The RF channel being used for connection to the WAP (read -only).
• This is determined through the WAP.
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.
