BEFORE YOU BEGIN
Thank you and congratulations on your purchase of the ESTeem
Model 195Eg Wireless Ethernet Radio Modem! This manual was
written to help both the first time and advanced user of the 195Eg
configure the radio modem for your application. If this your first
time configuring the 195Eg and you would like to get going as soon
as possible, we recommend using the 195Eg Quick Start Guide
provided with the modem. A copy of the guide is listed in the
appendix of this manual for your reference.
The ESTeem 195Eg is a very versatile wireless Ethernet networking device. To keep the manual usably short, many of the
application descriptions and programming details assume the user has a good working knowledge of the following network
concepts:
•General Ethernet networking and the configuration of LAN topologies
•Common Ethernet terminology and acronyms
•TCP/IP network protocol structure and how to configure TCP/IP networks and subnets
•How to identify and set the TCP/IP address on your computer
•Have administrator privileges to the computer and network you are configuring
•If using routing protocols, you must be able to identify and configure the network routers, gateways and firewalls
•You must be familiar with using web browser software such as Internet Explorer, Netscape or Mozilla
If you are unfamiliar with any of the above networking concepts, you may need to contact your network administrator for
assistance.
MODEL 195Eg OVERVIEW
The ESTeem Model 195Eg is a IEEE 802.11g
protocol compatible wireless LAN transceiver
that can be used to build a Wireless Local Area
Network (WLAN) for line-of-sight distances to
13 miles for fixed base and 5 miles for mobile
applications at RF data rates up to 54 Mbps.
The Model 195Eg is also downward compatible
with IEEE 802.11b protocol networks. The IEEE
802.11 WLAN was designed to look and feel like
any IEEE 802 wired LAN. The Model 195Eg is a
very sophisticated networking device that can
be configured for multiple modes of operation
depending upon the needs of the wireless and
wired LAN system. The following configuration
modes are provided as an overview of the basic
network types, as all possible network
configurations can not be listed. For further
help in selecting the correct network type,
please contact Customer Support at 509-735-
9092. Figure 1- Access Point Bridge Diagram

CHAPTER 1
INTRODUCTION
Revised: 27 Jul 05 1-2 EST P/N AA107G
MODEL 195Eg CONFIGURATION MODES
The Model 195Eg can be configured for multiple
modes of operation without any changes to the
hardware:
Access Point Modes
1. Access Point Bridge Mode. When the
Model 195Eg is configured as an Access
Point it will provide a wireless bridge from a
hardwired Local Area Network (LAN) to
laptops, office computers, Personal Digital
Assistants (PDA’s), video cameras, PLC’s,
etc. that have integral or external 802.11g or
802.11b wireless devices or other Model
195Eg modems in client modes. Multiple
Access Point Bridge modems can be
physically connected to the same network
(LAN) or through a radio link using the
Access Point Repeater mode to provide
overlapping, seamless Ethernet communication for mobile devices. The ESTeem Model 195Eg in Access Point Bridge mode
will pass all network traffic between connected devices including global network broadcasts. See Figure 1.
2. Access Point Router Mode. In this mode the ESTeem Model 195Eg will function as a router between the wired Ethernet
network, connect to the 195Eg’s Ethernet port, and the wireless network of 802.11g/b clients and other 195Eg’s in repeater
peer mode. As in all standard router configurations, the wireless and wired Ethernet networks will need to be on separate
subnets. To communicate from the wired Ethernet network to devices on the wireless network, a separate router (in
addition to the Model 195Eg) is required. The 195Eg in Access Point Router mode will pass network traffic for connected
devices but will block global
network broadcasts from the wired
network. This mode of operation
should be used instead of the
Access Point Bridge mode when a
separation between networks is
required or the ESTeem is
connected to larger LAN Networks
that will continuously send global
network broadcasts (Figure 2).
3. Access Point Masquerade Mode.
The Access Point Masquerade
mode is a special use of the Access
Point mode where the Model 195Eg
will connect 802.11g or 802.11b
wireless devices as clients into a
single static IP address on a wired
network. Data requests from the
wireless network will be processed
Figure 2 – Repeater Mode Diagram
Figure 3- Access Point Masquerade Diagram

CHAPTER 1
INTRODUCTION
Revised: 27 Jul 05 1-3 EST P/N AA107G
through the Access Point Masquerade 195Eg, but any request from the wired Ethernet network to devices on the wireless
network will be rejected similar to the operation of a “firewall”. The 195Eg will hide all the IP addresses connected on the
wireless link. You should use this mode of operation if Model 195Eg 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 195Eg (Figure 3).
This mode should also be used for attaching the Model 195Eg 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 enhancement of the 802.11g Access Point mode only
available the ESTeem Model 195Eg. The Access Point Repeater can be used with any of the above Access Point modes.
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 802.11g/b Clients. In addition to greatly extending
the Access Point canopy range, the Model 195Eg 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 802.11g/b Client devices or the Model 195Eg 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
195Eg 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 (802.11g Client) Modes
6. EtherStation Mode. This is a unique feature of the Model 195Eg when used in any Access Point network. 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 as an 802.11g client. The 195Eg will seamless roam under the
radio canopy of Access Point and can provide greatly increased range over a Wireless LAN Card for mobile Ethernet
devices such as vehicles, forklifts, cranes, etc (Figures 1-3).

INTRODUCTION

7. Station Router Mode. The Station Router mode will also function as an 802.11g client, similar to EtherStation, but will allow
multiple Ethernet devices to be connected to a single 195Eg (Figure 3). The 195Eg 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
195Eg in a mobile client application and the connected Ethernet devices will need to be accessible from the Access Point’s
LAN network.
8. Station Masquerade Mode. The Station Masquerade Mode is another mode where multiple devices will be connected to a
single ESTeem in a mobile or Client application, but unlike the Station Router mode, the Station Masquerate will consolidate
all connected Ethernet devices to a single IP address on the network. The devices connected to the Station Masquerade
195Eg will be able to access information from both the wireless and wired LAN, but will be inaccessible the other way similar
in application to a firewall. 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 from the LAN connected to the Access
Point. See Figure 3.
To begin setup of your wireless Ethernet network you must first configure the Model 195Eg for the mode desired. Chapter 2 will
show several examples of the different modes of operation to help select the correct mode for your application.

OVERVIEW
Most configuration of the ESTeem Model 195Eg is completed using the internal Web interface (discussed in detail in Chapter 4),
but to access the modem through a web browser requires first setting the TCP/IP address. The TCP/IP address (IP address) is
set at the factory for a static Class B (172.16.xxx.xxx - Mask 255.255.0.0) and listed on the ESTeem documentation. If this IP
address does not match your network configuration, you will need to use either the ESTeem 195E Discovery program or the RS-
232 interface to set the IP address in the 195Eg.
QUICK START GUIDE
A printed copy of the Model 195Eg Quick Start Guide was provided in the documentation package that arrived with your new
ESTeem 195Eg. This guide is an abbreviated step-by-step procedure on configuration of the 195Eg for most Ethernet bridging
