Distance: specify the distance value in miles using slider or enter the value manually. 
The signal strength and throughput falls off with range. Changing the distance value will 
change the ACK Timeout to the appropriate value of the distance. 
ACK Timeout: specify the ACK Timeout (20-520). This is the amount of time the 
subscriber station will wait to hear a acknowledgement response from the wireless 
device after the data packet is transmitted. If the timeout is set too short or too long, it 
will result poor connection and throughput performance. Changing the ACK Timeout 
value will change the Distance to the appropriate distance value for the ACK Timeout. 
Auto Adjust control will enable the ACK Timeout Self-Configuration feature. If enabled, 
ACK Timeout value will be derived dynamically using an algorithm similar to the 
Conservative Rate Algorithm described above.

 Features: select the checkboxes to enable the chosen SuperG® 
(PowerStation2 and LiteStation2) or SuperAG® (LiteStation5) features: 
Fast Frame – utilizes frame aggregation and timing modifications. 
Bursting – more data frames per given time period are transmitted. 
Compression – real-time hardware data compression is enabled. 
RSSI LED Thresholds 
RSSI LED Thresholds specify the marginal value of RSSI which will switch on LEDs 
indicating signal strength: 
Figure 17 – RSSI LED Thresholds Configuration 
LED 1 (Red) will switch on if the RSSI reach the value set in an entry field next to it. 
LED 2 (Yellow) will switch on if the RSSI reach the value set in an entry field next to it. 
LED 3 (Green) will switch on if the RSSI reach the value set in an entry field next to it. 
LED 4 (Green) will switch on if the RSSI reach the value set in an entry field next to it. 
Antenna 
PowerStation2 has a possibility to switch the antenna polarities with a single web 
management control. This is achieved by using Ubiquiti's patent-pending Adaptive 
Antenna Polarity (AAP) technology.
