BEFORE YOU BEGIN
Thank you and congratulations on your purchase of the
ESTeem Model 195Ea Wireless Ethernet Radio Modem!
This manual was written to help both the first time and
advanced user of the 195Ea configure the radio modem for
your application. If this is your first time configuring the
195Ea 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 195Ea 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 195Ea OVERVIEW
The ESTeem Model 195Ea is a wireless
LAN transceiver that can be used to build a
Wireless Local Area Network (WLAN) for
line-of-sight distances to 15 miles for fixed
base and 5 miles for mobile applications.
The 195Ea can provide RF data rates up to
54 Mbps and can have a serial port for
legacy RS-232 devices. The Model 195Ea 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: ESTeem Model 195Ea
Throughout this User’s Manual are
“Technical Tips” in boxes like this that
have been added to help answer the
most commonly asked questions.

CHAPTER 1
INTRODUCTION
Revised: 22 Aug 11 1-2 EST P/N AA107A
MODEL 195Ea CONFIGURATION
MODES
The Model 195Ea 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 – Example
Applications:
Access Point Modes
When the Model 195Ea is configured as an
Access Point it will provide a wireless
bridge from a hardwired Local Area
Network (LAN) to other Model 195Ea
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
195Ea in Access Point Bridge mode will pass all network traffic between connected devices including global network
broadcasts.
1. Access Point Bridge Mode
The ESTeem Model 195Ea in Access Point Bridge mode will both provide wireless access to mobile clients
(Access Point) and bridge all Ethernet data connected to the Ethernet 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
195Ea will function as a router
between wired Ethernet networks,
connected to the 195Ea’s Ethernet
port, and the wireless network of
mobile clients and other 195Ea’s. As
in all standard router configurations,
the wireless and wired Ethernet
networks will need to be on separate
subnets. The 195Ea 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 3: Repeater Mode Diagram
Figure 4: Access Point Masquerade Diagram

CHAPTER 1
INTRODUCTION
Revised: 22 Aug 11 1-3 EST P/N AA107A
3. Access Point Masquerade Mode
The Access Point Masquerade mode is a special use of the Access Point mode where the Model 195Ea will
connect multiple 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 195Ea, 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
195Ea will hide all the IP addresses connected on the wireless link. You should use this mode of operation if
Model 195Ea 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 195Ea (Figure 3). This mode should also be used
for attaching the Model 195Ea 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 can be used with any of the above Access Point modes. With this repeater
feature enabled, the Model 195Ea 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 195Ea 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 195Ea 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 195Ea 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.
Figure 5: Mesh Network Diagram

CHAPTER 1
INTRODUCTION
Revised: 22 Aug 11 1-4 EST P/N AA107A
Station (Client) Modes
1. EtherStation Mode. When the 195Ea is configured in the EtherStation Mode and attached to a single Ethernet
Device, the Model 195Ea will provide wireless mobile access to that device through a canopy of Access Points.
The 195Ea will 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).
2. Station Router Mode. The Station Router mode will also function as a client, similar to EtherStation, but will allow
multiple Ethernet devices to be connected to a single 195Ea (Figure 3). The 195Ea 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 195Ea 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 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
Masquerade will consolidate all connected Ethernet devices to a single IP address on the network. The devices
connected to the Station Masquerade 195Ea 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 195Ea 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.
Serial Applications. The ESTeem 195Ea
is installed with an RS-232 data port for
serial data applications run over the
broadband link (Figure 5). The serial over
broadband network can be used in a point-
to-point or point-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. Installing the serial port
option also provides a second 10/100
Base-T Ethernet port that can be used to
connect a second Ethernet device without
requiring a HUB/Switch or can be
configured as an external Router port.
To begin setup of your wireless Ethernet
network, continue to Chapter 2 - Staring
Out of this User’s Manual.

CHAPTER 2
STARTING OUT
Revised: 23 Aug 11 2-1 EST P/N AA107A
OVERVIEW
There are three main phases to prepare the ESTeem 195Ea for operation in a wireless network:
Phase 1 - Determine the correct mode of operation for the ESTeemin the wireless network. The ESTeem 195Ea is a
sophisticated networking device that can be configured for multiple modes of operation. Determining the correct mode of operation
for the ESTeem 195Ea is the first step. Chapter 3 of this User’s Manual details the modes of operation and applications 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 195Ea can be programmed for the wireless network. To simplify the programming of the Model 195Ea,
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 195Ea’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 in the Help section of the program itself.
The ESTeem Model 195Ea can also be programmed through the internal Web interface. If you do not have access to the ENC
Utility you can program the 195Ea for operation directly in the modem as detailed in Chapter 5.
3. Install the ESTeemhardware and test communication. After the ESTeem Model 195Ea’s programming, install the
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 instructions on testing and troubleshooting the wireless link,
refer to Appendix F (Troubleshooting).
MODEL 195Ea HARDWARE LAYOUT
To begin the configuration, unpack the ESTeem Model 195Ea shipping boxes and locate the items contained below for initial
configuration. Take a few minutes to inventory your equipment before you proceed. Report any missing or damaged items to
Customer Support (509-735-9092) as soon as possible. Each node in your ESTeem Model 195Ea’s network may have different
hardware components based upon the final installation location (i.e Outdoor, Indoor, Point-to-point or Muti-Point). Antenna types,
cable lengths, power supplies may be different, but the following items will be required for basic setup:

MODES OF OPERATION
The ESTeem Model 195Ea 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 195Ea is the Ethernet bridge mode. The
Ethernet bridge mode will connect two or more ESTeem 195Ea’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 195Ea 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 195Ea’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)

Router Modes (AP Router and AP Masquerade)
The ESTeem 195Ea 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)
Figure 4: Router Mode Example

CHAPTER 3
EXAMPLE APPLICATIONS
Revised: 6 Sep 11 3-4 EST P/N AA107A
Mobile Client Modes (EtherStation, Station Router or Station Masquerade)
The ESTeem 195Ea can also be configured to function as a mobile client. The client modes will allow the 195Ea to
seamlessly roam between other 195Ea configured as Access Points (AP). These Access Points can be ESTeem
195Ea’s configured in one of the three Access Point modes (AP Bridge, AP Router or AP Masquerade – see above).
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 195Ea. If you are connecting the
195Ea 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 195Ea
and the wireless network, while the Station Masquerade will serve as a firewall on the Ethernet side.
Example Applications
 Mobile applications where the 195Ea 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

PROGRAMMING EXAMPLES
Once the mode of operation for the ESTeem has been
determined, you are now ready to program the Model 195Ea 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 195Ea’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 6), select , select ESTeem from the menu items to display the drop down
menu, then select New>New ESTeem.
2. Enter in the ESTeem Model 195Ea serial numbers used for
the example (for example enter E-14000 in the Set Serial
Number Box) and press the OK button (Figure 7). The ENC
Utility will look up the ESTeem 195Ea’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
8).
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.
