To add NEW subscriber units to the access point

1)   Disconnect the AP from the network and disconnect power from the AP.
2)   Connect an Ethernet cable from the AP to the SU (key exchange will not work through a switch or hub — crossover cables are not 
      required).
3)   Plug in the NEW SU, then plug in the AP. The units will automatically exchange keys over the Ethernet cable.
4)   Repeat steps 2 and 3 until all SUs are successfully programmed.
5)   Power cycle all radios for the new keys to take effect.
6)   Reconnect the AP to the network and deploy the new SU radios.

To re-key a subscriber unit to a NEW access point

1)   Select the radio that will operate as the access point (AP) and set DIP switch 1 ON to enable access point operation.
2)   Plug in the NEW AP.
3)   Connect an Ethernet cable from the AP to the SU (key exchange will not work through a switch or hub — crossover cables are not 
      required).
4)   Plug in the SU.
5)   Repeat steps 3 and 4 until all SUs are successfully programmed.
6)   Power cycle all radios for the new keys to take effect.
7)   Deploy the radios.

The AW900iT and AW900xT are designed to automatically select and continuously optimize the performance of its radio channel. 

The radio channel is monitored to ensure it is providing low error rates necessary for successful data transmission. In the event that 

the error rate rises, the access point will autonomously change to a new channel. There are 12 non-overlapping channels.

The operation of the AW900iT and AW900xT can be restricted to a specific channel within the 900 MHz band by setting DIP

switches 3-8 on the access point as shown in the table on Page 6. The subscriber unit responds to the access point’s choice of

channel and its DIP switches have no effect and do not need to be selected.
