Once the key sharing is complete the AP and SU change their LED displays in confirmation of the
successful programming:
The SU blinks one of the Green Link Quality LEDs.
The AP illuminates the LED labeled RF RX and the AP remains in “key exchange mode.”
If the user’s needs change:
Additional SUs can be added to the network
An SU can be reprogrammed to join a different network
An SU can be changed into an AP
An AP can be changed into a SU.
The radios cannot be damaged by incorrect programming. If DIP 1 is accidentally toggled then DIP
1 can be turned back and the radio still retains all the network associations it had in its previous
mode (assuming that the radio had not yet successfully key exchanged with a new network). An AP
can be reset by programming it as a SU to a new AP and then turning it back into an AP again.
SUs that have not yet received a network key boot up in “key exchange mode” and wait to receive a
key. SUs that have received a network key will boot up for 5 seconds in “key exchange mode” and
will look to see if a new AP is present. If a new AP is present, then the SU exchanges keys with the
AP, otherwise the SU begins normal operation after the 5 seconds.
APs that have not yet issued network keys boot up in “key exchange mode” until they have issued
network keys to at least 1 SU. Once the AP has issued keys it will only boot up for 5 seconds in “key
exchange mode.” If a SU is present during the 5 seconds, then the AP will issue new keys to the SU
and will then remain in “key exchange mode,” waiting for more SUs to be attached. Once all new
SUs have been attached, the AP must be power cycled. The AP will boot up and will enter normal
operation after 5 seconds of “key exchange mode.”
Initial Setup Steps
1) Select the radio that will operate as the access point (AP) and set DIP switch 1 ON to enable
AP operation.
2) Plug in the access point.
The LINK QUALITY LEDs will blink sequentially showing that the radio is hunting for a
subscriber unit (SU) to share keys with.
3) Plug in a subscriber unit.
The LINK QUALITY LEDs will blink sequentially showing the radio is hunting for an AP
to supply a network key.
4) Connect an Ethernet cable from the AP to the SU and the units will automatically exchange
keys over the Ethernet cable (key exchange will not work through a switch or hub —
crossover cables are not required).
On the AP, the LINK QUALITY LEDs will still show that the radio is still in “key
exchange mode” and the RF TX LED will be lit showing that the keys exchanged
successfully — ignore the other LEDs.
