operation if Model 195Es is connected directly to the Internet with a static IP address (DSL, T1, etc.) and you want the
wireless clients to access the information through the Model 195Es (Figure 3). This mode should also be used for attaching
the Model 195Es to a network where few IP addresses are available or a firewall for the wireless clients is required.
4. Access Point Repeater. The Access Point Repeater is a unique feature available the ESTeem Model 195Es. The Access
Point Repeater can be used with any of the above Access Point modes. With this repeater feature enabled, the Model 195Es
Access Points do not have to be hardwired together on the same physical LAN to provide seamless Ethernet communication
for roaming 195Eg clients. In addition to greatly extending the Access Point canopy range, the Model 195Es will also bridge
any Ethernet device or Ethernet network 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 Model 195Es in the Client mode to simultaneously
roam under the network canopy.
5. Self-Healing Mesh Network. If multiple Access Point Repeater routes are configured to the same destination ESTeem,
the 195Es will create a “self-healing” mesh network by automatically re-routing data through alternate paths to reach its
destination if the primary path is inoperable. The routing and priority of alternate paths is completely user configurable.
See Figure 4.
Station (Client) Modes
6. EtherStation Mode. When the 195Es is configured in the EtherStation Mode and attached to a single Ethernet Device, the
Model 195Es seamless roam under the radio canopy of Access Point and can provide greatly increased range for mobile
Ethernet devices such as vehicles, forklifts, cranes, etc (Figures 1-3).
7. Station Router Mode. The Station Router mode will also function as a mobile client, similar to EtherStation, but will allow
multiple Ethernet devices to be connected to a single 195Es (Figure 3). The 195Es will function as a router between the
wireless client mode and the wired Ethernet devices connected to the Ethernet port. Similar in configuration to the Access
Point Router mode, the wireless and wired Ethernet networks will need to be on separate subnets. To communicate from
wireless network to devices on the wired Station Router network, a separate router (connected to the Ethernet side of the
Access Point) is required. This mode would be used where multiple Ethernet devices will be connected to a single Model
