    SA-DS.11’s LAN sends a message that is not destined for a local station, the SA-DS.11 wirelessly forwards the message to the AP-DS.11. When the AP-DS.11 receives a message destined for a station on the SA-DS.11's LAN, the AP-DS.11 wirelessly forwards it to the SA-DS.11. In this manner, the SA-DS.11 and the AP-DS.11 work together like a standard network bridge.

    The first time each station on the SA-DS.11’s LAN sends a message, the station’s address is registered in the SA-DS.11 and the AP-DS.11. The SA-DS.11 and AP- DS.11 can hold all the addresses necessary to support an entire LAN connected to a SA-DS.11.

In such instances, use the AP-DS.11 with the omni-6 antenna kit (6dbi omni- directional antenna with 6 feet LMR-600 cable). In the USA (FCC regulated) and in non-regulated countries, the omni-6 comes with a shorter antenna cable, extending the coverage area.
