INTRODUCTION
BEFORE YOU BEGIN
Thank you and congratulations on your purchase of the ESTeem
Model 195E Wireless Ethernet Radio Modem! This manual was
written to help both the first time and advanced user of the 195E to
configure the wireless modem for your application. If this is your
first time configuring the 195E and you would like to get going as
soon as possible, we recommend using the ESTeem Resource CD
provided with the modem. The Resource CD will provide the
software utilities and guide you through the configuration of the
wireless modem for your application.
The ESTeem 195E series wireless modems are very sophisticated
networking devices. 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 195E OVERVIEW
The ESTeem Model 195E is a series of wireless
LAN transceivers that can be used to build many
types of Wireless Local Area Networks (WLAN).
The wireless modems in 195E series can provide
RF data rates up to 54 Mbps and have an RS-232
serial port for legacy device networks. The Model
195E 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 refer

CHAPTER 1
INTRODUCTION
CONFIGURATION MODES
A Model 195E can be configured for multiple
modes of operation without any changes to the
hardware. The following are brief descriptions
of the configuration modes. For detailed
descriptions and suggested applications for
each mode, please refer to Chapter 4.
Access Point Modes
When a Model 195E is configured as an Access
Point it will provide a wireless bridge for
mobile clients such as Model 195E modems in
client modes or Wi-Fi devices with the 195Eg
and 195Ea. Multiple Access Points 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.
1. Access Point Bridge Mode
An ESTeem Model 195E in Access Point Bridge mode will both provide wireless access to mobile clients (Access Point)
and bridge all Ethernet data connected to the Ethern et ports. The AP Bridge mode will pass all network traffic between
connected devices including global network broadcasts. (See Figure 2)
2. Access Point Router Mode
In this mode the ESTeem Model 195E will function as a router between wired Ethernet networks, connected to the
195E’s Ethernet port, and the
wireless clients in the network. As in
all standard router configurations, the
wireless and wired Ethernet networks
will need to be on separate subnets.
The 195E 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 3).

Figure 4: Access Point Masquerade Diagram
CHAPTER 1
INTRODUCTION
3. Access Point Masquerade Mode
The Access Point Masquerade mode is a special use of the Access Point mode where the Model 195E will connect
mobile clients into a single static IP address on a wired network. Data requests from the wireless network will be
processed through the Access Point Masquerade 195E, 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 195E will hide all the IP addresses
connected on the wireless link. You would use this mode of operation if Model 195E is connected directly to the Inte rnet
with a static IP address (DSL, T1, etc.) and you want the wireless clients to access the information through the Model
195E (Figure 4). This mode should also be used for attaching the Model 195E to a network where few IP addresses are
available or a firewall for the wireless clients is required.
Access Point Repeater
The Access Point Repeater is a unique enhancement of the ESTeem Model 195E series. The Access Point Repeater can
be used with any of the above Access Point modes. With this repeater feature enabled, the Model 195E Access Points do
not have to be hardwired together on the same physical LAN to provide seamless Ethernet communication for roaming
clients. In addition to greatly extending the Access Point canopy range, the Model 195E 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 the Model 195E in the Client mode to simultaneously
roam under the network canopy.
Self-Healing Mesh Network
If multiple Access Point Repeater routes are configured to the same destination ESTeem, the 195E 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 5)

CHAPTER 1
INTRODUCTION
Station (Client) Modes
1. EtherStation Mode
When the 195E is configured in the EtherStation mode and attached to a single Ethernet Device, the Model 195E will
emulate an 802.11 wireless card in functionality for communication as a mobile client. The 195E will seamless roam
under the radio canopy of Access Points and can provide greatly increased range over a Wireless LAN Card for mobile
Ethernet devices such as vehicles, forklifts, cranes, etc (Figures 2-4).
2. Station Router Mode
The Station Router mode will also functions as a mobile client, similar to EtherStation, but will allow multiple Ethernet
devices to be connected to a single 195E (Figure 4). The 195E 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 195E in a
mobile client application and the connected Ethernet devices will need to be accessible from the Access Point’s LAN
network.
3. Station Masquerade Mode
The Station Masquerade mode is another case multiple devices will be connected to a single ESTeem in a mobile or
client application. However, unlike the Station Router mode, the Station Masquerade will consolidate all connected
Ethernet devices to a single IP address on the network. The devices connected to the Station Masquerade 195E 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
195E in a mobile application and the IP addresses for each device will be hidden from the LAN connected to the Access
Point. See Figure 4.

CHAPTER 1
INTRODUCTION
RS-232 Serial Applications
The ESTeem 195E is installed with an RS-232 data port for serial data applications run over the broadband link (Figure
6). The serial over broadband network can be used in a po int-to-point or p oint-to-multi-point application for networking
serial (RS-232C) devices, providing serial connections to legacy hardware in a new Ethernet network or providing for
high-bandwidth devices (such as Video or Voice over IP) in an existing serial network.

CHAPTER 2
STARTING OUT
OVERVIEW
There are three main phases to prepare the ESTeem 195E for operation in a wireless network:
Phase 1 - Determine the correct mode of operation for the ESTeem in the wireless network. The ESTeem 195E is a
sophisticated networking device that can be configured for multiple modes of operation. Determining the correct mode of
operation for the ESTeem 195E is the first step. Chapter 3 of this User’s Manual detail s the m odes of operati on and appli cations
where each would be used.
Phase 2 - Program the ESTeem for operation in the wireless network. Once the correct mode of operation for the ESTeem
has been determined, the 195E can be programmed for the wirel ess network. To simplify the programming of the Model 195E,
ESTeem has created a new software utility called the ESTeem Network Configuration (ENC) Utility which is used to graphically
configure the primary and backup communication routes between ESTeem 195E’s in the network. The ENC Utility can be
installed from the ESTeem Resource Disk or from the ESTeem web site (www.esteem .com ). Chapter 4 (Utilities and Features) of
this User’s Manual will guide you in the installation of the software and give a brief overview of operation of the ENC Utility, but
a detailed User’s Guide is available both on the ESTeem Resource Disk and i n the Help secti on of the program i tself.
The ESTeem Model 195E can also be programmed through the internal Web interface (discussed in detail in Chapter 5) if you do
not have access to the ENC Utility or your firmware version is older version 799.
Phase 3 - Install the ESTeem hardware and test communication. After the ESTeem Model 195E’s programming, inst all t he
hardware in each remote location. Chapter 8 of this User’s Manual describes the antenna specifications, mounting options and the
configuration of the pole mounting hardware for the ESTeem. For instructi ons on test ing and t roubleshooti ng the wirel ess li nk,

EXAMPLE APPLICATIONS
MODES OF OPERATION
The ESTeem Model 195E is a sophisticated wireless networking device that can be configured for multiple modes
of operation. Determining the correct mode of operation for the ESTeem is the first step in creating a reliable
wireless network. This chapter will explain each mode of operation, provide example applications and detailed
programming information for each mode. Please review the following modes of operations. If you do not see an
example of your application, please contact ESTeem support at 509-735-9092 for help in selecting your mode of
operation.
Ethernet Bridge Mode (AP Bridge)
The most commonly used mode of operation with the ESTeem Model 195E is the Ethernet bridge mode. The
Ethernet bridge mode will connect two or more ESTeem 195E’s while passing all network traffic that arrives in both
the wireless and connected Ethernet ports; including all global network traffic (Figure 1). This mode will work in
most wireless applications of the 195E to wirelessly connect two or more remote Ethernet devices or networks. The
Ethernet bridge mode is also used in repeating (Figure 2) and in self-healing Mesh networks (Figure 3) for fixed
(non mobile) applications.
Example Applications
• Building to building remote wireless LAN networks
• Point to point wireless Ethernet communication devices
• Multi-point wireless Ethernet networks
• Remote Supervisory Control and Data Acquisition (SCADA) networks
• Redundant, self-healing Mesh networks
• Fixed locations with mobile ESTeem 195E’s
Applications Where Ethernet Bridge Mode Not Used
• Mobile applications (see Mobile Clients)
• Connections to large Ethernet traffic networks such as large office buildings or plant networks (see Router
modes)

CHAPTER 3
EXAMPLE APPLICATIONS
Router Modes (AP Router and AP Masquerade)
The ESTeem 195E can be configured as a network router or network firewall between the Ethernet LAN connection
and the wireless network of remote locations. The router modes are used to limit the network traffic from a busy
Ethernet network connection to only those specific IP address used on the wireless network (see Figure 4). The
Ethernet router mode (AP Router) will allow bi-directional communication from the Ethernet LAN connection to the
wireless network. The Ethernet firewall mode (AP Masquerade) will allow Ethernet devices in the wireless network
to request information from the Ethernet LAN network and receive a response, but no traffic can be generated from
the Ethernet LAN side.
Example Applications
• Wireless Ethernet networks connected to large company or plant Ethernet LAN networks (AP Router)
• Wireless Ethernet networks with a requirement for network isolation from the plant or company network
(AP Router)
• Shared Ethernet connection to direct Internet service (DSL, Cable, T1, etc.) (AP Masquerade)
Applications Where Ethernet Router Mode Not Used
• Mobile applications (see Mobile Clients)
• Simple network connections only using a single IP network subnet (see Ethernet Bridge modes)

CHAPTER 3
EXAMPLE APPLICATIONS
Mobile Client Modes (EtherStation, Station Router or Station Masquerade)
The ESTeem 195E can also be configured to function as a mobile client. The client modes allow the 195E to
seamlessly roam between fixed Access Points. These Access Points can either be ESTeem 195E wireless
modems configured in one of the three Access Point modes (AP Bridge, AP Router or AP Masquerade – see
above) or any IEEE 802.11 (Wi-Fi) Access Point for the ESTeem 195Eg and 195Ea. The client modes will allow
mobile Ethernet devices to connect to each other or to an Ethernet LAN through the fixed AP (Figure 5).
The EtherStation mode is used to connect a single Ethernet device to the ESTeem 195E. If you are connecting the
195E to multiple Ethernet devices in a mobile mode, the Station Router or Station Masquerade will be required.
The Station Router will allow bi-directional communication between the Ethernet devices connected to the 195E
and the wireless network, while the Station Masquerade will serve as a firewall on the Ethernet side.
Example Applications
• Mobile applications where the 195E will change links often between fixed Access Points
• Long range mobile client networks
• Public safety applications for police, fire and EMS
Applications Where Mobile Client Mode Not Used
• Fixed locations using Ethernet Bridging or Routing
• Wireless Ethernet networks with repeaters

CHAPTER 3
EXAMPLE APPLICATIONS
802.11 Access Point Modes (AP Bridge, AP Router or AP Masquerade) (195Eg and 195Ea Only)
The ESTeem 195E can be configured as a high power 802.11 Access Point (AP). The IEEE 802.11g/b Access
Point (AP) functionality is available in all three of the Access Point modes (AP Bridge, AP Router or AP
Masquerade). The Access Point mode will provide either a single wireless connection (Figure 6) or overlapping
coverage (Figure 7) to create a “canopy” of wireless coverage for 802.11 devices. The ESTeem 195E in AP mode
can function as both an Ethernet bridge or router and 802.11 AP simultaneously (Figure 8).
Example Applications
• Industrial, long range 802.11 (Wi-Fi) networks
• Hybrid networks of Ethernet bridging/routing and mobile client access
Applications Where Access Point (AP) Mode Not Used

PROGRAMMING EXAMPLES
Once the mode of operation for the ESTeem has been
determined, you are now ready to program the Model 195E for
use. ESTeem has created a simplified network programming
utility call the ESTeem Network Configuration (ENC) Utility. This
ENC Utility will be used in all the following programming
examples. For detailed instructions on installing the ENC Utility,
please refer to the User’s Guide (found in the ESTeem Resource
CD or Utility program itself) or Chapter 4 of this User’s Manual
Adding ESTeems to ENC Utility and Changing Name
Each of the example applications will use the following procedure to add and rename ESTeem 195E’s.
1. Consult the ENC Utility’s User Guide on how the create a new wireless network. Once you have a blank
network configuration page (Figure 9), select ESTeem from the menu items to display the drop down menu,
then select New>New ESTeem.
Technical Tip: The ENC Utility calculates the
wireless link information based upon exact
ESTeem serial numbers. The serial numbers
listed in the following examples are for example
only. Enter the correct ESTeem serial numbers
for your application.
Figure 9: Adding ESTeem to Blank ENC Configuration Page
2. Enter in the ESTeem Model 195E serial numbers used for the
example (for example enter E-14000 in the Set Serial Number
Box) and press the OK button (Figure 10). The ENC Utility
will look up the ESTeem 195E’s serial number in the
database and match the correct Wireless LAN MAC (WLAN
MAC) address to the modem. This WLAN MAC address will
be displayed above the modem symbol on the screen
(Figure 11).

Setting the ESTeem for Mobile Client (station) mode with the ENC Utility is different than
the Bridge/Router or Access Point (AP) modes. ESTeem modems configured in as a
Mobile Client will not link with a specific fixed modem; but will roam between any 802.11
Access Point with the correct Network Name (SSID) and Encryption. The ESTeem
configured as a client is also not set on a specific operating frequency (channel) but will
scan all channels looking for the AP. Use the following procedure to configure an
ESTeem 195E in one of the three mobile client modes:
1. Starting a new network of ESTeem 195Es in
Mobile Client mode is the same as any of the
Bridge modes except when you are asked for the
frequency (channel) of operation, select “Station”
(Figure 23).
2. Add the three mobile client modems to the ENC
Utility configuration page as instructed above and
set the Modem ID to match the three modes of
operation. Your configuration will appear as in
Figure 24.
Figure 23: Station
Technical Tip: The ESTeem 195E’s in Mobile
Client modes do not have a specific frequency
of operation as can be seen in Figure 24.
Figure 24: Station Mode Example Modems
EtherStation
3. By default, the ENC Utility sets all station mode ESTeem
modems to EtherStation mode. The only adjustment
necessary to the EtherStation modem in our example is to
enter the connected Ethernet device’s MAC address. The
ESTeem 195E will “clone” the Ethernet MAC address of the
connected Ethernet device. To configure the EtherStation
modem, double-click on the icon to bring up the ESTeem
Summary window and press the Edit button (Figure 20).

802.11 AP network in which the EtherStation modem
will be working and press the Finish button to return to the configuration page.
10. Verify all ESTeem modems are connected to the same switch as the computer running the ENC Utility and
send the configuration to all modems at the same time by selecting ESTeem>ESTeem Configuration>Send
Configuration to All ESTeems. Once the ENC Utility has downloaded the configuration for both ESTeem
195Es, the status box around the ESTeems will change from yellow to blue. This indicates that the
configuration was completed successfully and the ESTeem 195Es are ready to be installed in the application.
802.11 Access Point Modes (Figures 6-8)
Access Point Bridge, Router or Masquerade Modes
Configuring the ESTeem 195E as an Access Point
for 802.11 clients (as seen Figures 6-8) is exactly
the same as configuration for AP Bridge, AP Router
and AP Masquerade as shown above. The only
difference being that a wireless link is only added
between ESTeem 195Es where a wireless
connection is necessary. In figures 6 and 7 there
would be no wireless link listed in the ENC Utility.
In figure 8, the configuration would be exactly as
shown in Figure 2 with the addition of the mobile
clients in the network.
The 802.11 clients will use the SSID configured
during the setup of the network with the ENC Utility.
The encryption will be set at the factory default
settings for clients (WPA PSK). To adjust the
encryption type, right-mouse click on the ESTeem
icon and select Change>Change ESTeem
