PRODUCT DESCRIPTION
The DataMover ESS-II and ESS transceivers are designed to provide
wireless local area network (LAN) service with plug-and-play hard-
ware. The transceivers come in two primary models—Access Point
and Remote.
Three types of Remote Gateways are available—the Ethernet Bridge,
the Serial Gateway, and the Dual Gateway supporting both IP/Ethernet
and serial services.
Table 1
summaries the different interface abilities
for each type of radio.
A transceiver can be configured by the owner to operate as an Access
Point or as a Remote with some restrictions. Only the Dual Gateway
Remote units can be reconfigured as an Access Point. Ethernet Bridge
and a Serial Gateway Remotes cannot be reconfigured as Access Point
unless they are first upgraded to Dual Gateway type. This is accom-
plished with an “Authorization Key” purchased from the factory. Each
one of these individual software keys is associated with the serial
number of the corresponding unit.
Transceivers serve as either an “Access Point” or “Remote.” An
Access Point (AP) is a wireless hub that usually provides connectivity
into a wired Ethernet LAN/WAN. From a radio perspective, an Access
Point serves as the network’s “master station” providing synchroniza-
tion data to all associated Remotes (RMT) within its network.
