VG Series Modero Touch Panels
Refer to both the Wireless Settings Page - Wireless Access Overview section on page 86 and Configuring a Wireless
Connection section on page 86 for more detailed information of setting up the Modero panel for wireless network
access.
Wireless Settings Page Elements (Cont.)
Wireless Settings (Cont.):
Current Key Displays the current WEP key in use. Keys may also be examined by touching the key
buttons and noting the keyboard initialization text.
• When working with a single panel and a single WAP, it is recommended that you
manually enter the Current Key from the WAP into the selected WEP Key.
• When working with a single WAP and multiple panels, it is recommended that you
generate a Current Key using the same passphrase on all panels and then enter the
panel-produced WEP key manually into the Wireless Access Point.
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.
Example: 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.
