Procedure
1. Verify the Remote transceiver is associated with an Access Point
unit by observing the condition of the
LINK
LED (
LINK LED = On or
Blinking
). This indicates that you have an adequate signal level for
the measurements and it is safe to proceed.
2. View and record the Wireless Packets Dropped and Received Error
rates.
(Main Menu>>Performance Information>>Packet Statistics>>Wireless Packet
Statistics)
This information will be used later.
3. Clear the Wireless Pack e ts Statistics history.
(Main Menu>>Performance Information>>Packet Statistics>>Wireless Packet
Statistics>>Clear Wireless Stats)
\
4. Read the RSSI level at the Remote.
(Main Menu>>Performance Information>>RSSI by Zone)
5. Optimize RSSI (less negative is better) by slowly adjusting the
direction of the antenna.
Watch the RSSI indication for several seconds after making each
adjustment so that the RSSI accurately reflects any change in the
link signal strength.
6. View the Wireless Packets Dropped and Received Error rates at the
point of maximum RSSI level. They should be the same or lower
than the previous reading.
(Main Menu>>Performance Information>>Packet Statistics>>Wireless Packet
Statistics)
If the RSSI peak results in an increase in the Wireless Packets
Dropped and Received Error , the antenna may be aimed at an undes-
ired signal source. Try a different antenna orientation.
