EST P/N AA107G
used for attaching the Model 195Eg to a
network where few IP addresses are
available or a separate, inaccessible
subnet for the wireless clients is
required.

Access Point Repeater Modes
. The
Access Point Repeater is a unique
enhancement of the 802.11g Access
Point mode. This feature is available
only in the ESTeem Model 195Eg. With
this repeater feature enabled, the Model
195Eg Access Points do not have to be
hardwired together on the same
physical LAN to provide seamless
Ethernet communication for roaming
802.11b/g Clients. On power up the
Model 195Eg will automatically
associate with other Model 195Egs
programmed with the same
configuration (i.e. SSID, Frequency,
Security, etc.) for routing message traffic over the wireless Ethernet network. If there are multiple routes to a destination,
this feature will create a “self-healing” network by automatically re-routing data through an alternate path to reach its
destination if the primary path is inoperable. When programmed in any of the Access Point modes, the Model 195Eg will
also bridge any Ethernet network or Ethernet device connected to the unit over this same wireless Ethernet network. This
mode gives the user the features of a point to multi-point bridge network but also allows 802.11b/g Client devices or the
Model 195Eg in the Client mode to roam under the network. See Figure 3.
5.
EtherStation Mode
. This is a special feature of the Model 195Eg when used in an Access Point application. When the
195Eg is configured in the EtherStation Mode and attached to a single Ethernet Device, the Model 195Eg will emulate an
802.11g PCMCIA wireless card in functionality for communication to an 802.11g Access Point. This mode can provide
greatly increased range over a Wireless LAN Card for mobile Ethernet devices such as vehicles, forklifts, cranes, etc. See
Figures 1 - 3.
6.
Station Router Mode
. This is a special feature of the Model 195Eg when used in an Access Point application where
multiple devices will be connected to a single ESTeem in a mobile or Client application. When the 195Eg is configured in
the Station Router Mode and attached to multiple Ethernet devices, the Model 195Eg will emulate an 802.11g client in
functionality for communication to an 802.11g Access Point. This mode would be used where multiple Ethernet devices will
be connected to a single Model 195Eg in a mobile application and the
IP addresses for each device will be visible on the
LAN
connected to the Access Point. See Figure 2.
7.
Station (Router) Masquerade Mode
. This is a special feature of the Model 195Eg when used in an Access Point application
where multiple devices will be connected to a single ESTeem in a mobile or Client application. When the 195Eg is
configured in the Station Router Mode and attached to multiple Ethernet devices, the Model 195Eg will emulate an 802.11g
client in functionality for communication to an 802.11g Access Point. This mode would be used where multiple Ethernet
devices will be connected to a single Model 195Eg in a mobile application and the
IP addresses for each device will be
hidden on the LAN
connected to the Access Point. See Figure 2.
To begin setup of your wireless Ethernet network you must first configure the Model 195Eg for the mode desired. Chapter 2 will
show you how to begin programming the Model 195Eg.
