When a station on the Ethernet LAN sends a message that is
not destined for a local station, the RB-DS.11 forwards the
message to the BU-DS.11. When the BU-DS.11 receives a
message destined for a station on the RB-DS.11's LAN, the
BU-DS.11 forwards it to the RB-DS.11. In this manner, the
RB-DS.11 and the BU-DS.11 work together like a standard
network bridge.
The first time each station on the RB-DS.11’s LAN sends a
message, the station’s address is registered by both the RB-
DS.11 and the BU-DS.11. It is possible for the RB-DS.11 and
BU-DS.11 to store all the addresses necessary to support an
entire LAN connected to a RB-DS.11.
The RB-DS.11 comes in two options: The RB-DS.11 and the
RB-DS.11D.
The RB-DS.11 is the basic unit, equipped with an antenna
integrated into the front cover of the outdoor unit.
The RB-DS.11D has no integral antenna and is equipped
with an antenna connector (on the outdoor unit) for the
connection of an external antenna (not included with the
unit). When this unit is ordered, a protective sun cover is
supplied with the unit and should be mounted on the front
of the outdoor unit. Refer to Antennas for Outdoor
Applications on page 2-8 and Available Antennas on page 2-
10 for information on how to select an external antenna.
