MODEL 195C/M OVERVIEW
Figure 2: Access Point Bridge Diagram
The ESTeem Model 195C/M and 195C/M are
wireless modem transceivers that can be used to
build many types of Wireless Local Area
Networks (WLAN). The ESTeem 195C/M series
have both and Ethernet interface and an RS-232
serial port for legacy device networks. The Model
195C/M 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
to Chapter 4 of this User’s Manual or call
Customer Support at 509-735-9092.

CHAPTER 1
INTRODUCTION
Revised: 1 Oct 13 1-2 EST P/N AA107-195CM
CONFIGURATION MODES
A Model 195C/M 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 Bridge Mode
When a Model 195C/M is configured as an
Access Point Bridge it will provide a wireless
bridge for mobile clients. 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. Figure 3: Repeater Mode Diagram
An ESTeem Model 195C/M 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).
Repeater Mode
The Repeater Mode can be used with any of the above Access Point modes. With this repeater feature enabled, the Model
195C/M 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 195C/M 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 195C/M in the Client mode to
simultaneously roam under the network canopy.
Self-Healing Mesh Network
If multiple repeater routes are configured
to the same destination ESTeem, the
195C/M 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
EtherStation (Client) Mode
When the 195C/M is configured in the EtherStation mode and attached to a single Ethernet Device, the Model 195C/M will
emulate a wireless card in functionality for communication as a mobile client. The 195C/M will seamless roam under the radio
canopy of Access Points and can provide wireless communication for mobile Ethernet devices such as vehicles, forklifts, cranes,
etc (Figures 2&3).
RS-232 Serial Applications
The ESTeem 195C/M is installed with an RS-232 data port for serial data applications run over the wireless links (Figure 6). The
serial 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.

CHAPTER 2
STARTING OUT
Revised: 1 Oct 13 2-1 EST P/N AA107-195CM
OVERVIEW
There are three main phases to prepare the ESTeem 195C/M for operation in a wireless network:
Phase 1 - Determine the correct mode of operation for the ESTeem in the wireless network. The ESTeem 195C/M is a
sophisticated networking device that can be configured for multiple modes of operation. Determining the correct mode of
operation for the ESTeem 195C/M 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 195C/M can be programmed for the wireless network. To simplify the programming of the Model
195C/M, 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 195C/M’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 195C/M 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.
Phase 3 - Install the ESTeem hardware and test communication. After the ESTeem Model 195C/M’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 195C/M HARDWARE LAYOUT
To begin the configuration, unpack the ESTeem Model 195C/M shipping boxes and locate the items 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 195C/M’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:

CHAPTER 3
EXAMPLE APPLICATIONS
MODES OF OPERATION
The ESTeem Model 195C/M 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 195C/M is the Ethernet bridge mode. The Ethernet
bridge mode will connect two or more ESTeem 195C/M’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 195C/M 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 195C/M’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 195C/M 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.
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
Revised: 1 Oct 13 3-3 EST P/N AA107-195CM
CHAPTER 3
EXAMPLE APPLICATIONS
Mobile Client Modes (EtherStation, Station Router or Station Masquerade)
The ESTeem 195C/M can also be configured to function as a mobile client. The client modes allow the 195C/M to seamlessly
roam between fixed Access Points. 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 195C/M. If you are connecting the 195C/M
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 195C/M and the wireless network,
while the Station Masquerade will serve as a firewall on the Ethernet side.
Example Applications
• Mobile applications where the 195C/M 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
• Mobile applications

CHAPTER 3
EXAMPLE APPLICATIONS
PROGRAMMING EXAMPLES
Once the mode of operation for the ESTeem has been determined, you
are now ready to program the Model 195C/M 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.
Technical Tip: The ENC Utility calculates the

Serial Numbers:
E-14000 (EtherStation)
E-14001 (Station Router)
E-14002 (Station Masquerade)
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 195C/M in one of the three mobile client modes:
1. Starting a new network of ESTeem 195C/Ms 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.

CHAPTER 6
SERIAL APPLICATIONS
USING THE RS-232 DATA PORT
The ESTeem 195C/M has a serial data port that can provide RS-232 communication between two or more serial devices using the
wireless broadband link. The serial data is encapsulated and transferred as a standard Ethernet packet over an operating 195C/M
wireless Ethernet system. The configuration for a serial 195C/M network will be the same as an Ethernet or a serial (RS-232)
based communication network.
The serial interface option can be used to link two or more serial devices in a new or existing system. The serial data has very little
impact on the network bandwidth and will allow for both Ethernet and serial applications simultaneously. A possible application
would be installation of the 195C/M in an existing serial based network that was looking for future upgrade to an Ethernet based
system. Another would be using the high-bandwidth Ethernet connections to provide a link to remote video hardware while also
providing a serial link to the existing PLC in a SCADA type application.
Figure 4: 195C/M Front Panel Overview
SERIAL CONNECTIONS
The 9-pin Sub-D serial data port is located on the face of the
195C/M (Figure 4). Using the ESTeem AA062 interface
cable, the 195C/M can be connected to a standard DTE-device
(PC) with a male 9-pin Sub-D connector. The complete cable
configuration is available in Appendix C – Interface Ports.
SERIAL CONFIGURATION
Configuration of the serial port is completed during the
standard setup of the 195C/M. After completion of the
Repeater Peer configuration screen, the Serial Port Setup
screen (Figure 5) will be displayed. Each section in the Serial
Port Setup screen is described in detail with the following:
Enable the RS-232 Data Port
Enabling the serial data port allows the modem to send RS-232 data over the broadband wireless connection established with the
ESTeem repeater peers. The modem can be configured in a point-to-point or point-to-multipoint system. Select Yes if you wish to
enable the serial data port.
Mode of Operation
There are two distinct modes of operation for the serial port in the 195C/M. The Redirector mode will provide two-way serial
communication between two or more serial devices, while the Terminal Server mode will allow serial communication to a specific
remote site by connecting through telnet or SSH. Select one of the following modes of operation:
Full Redirector Mode - This mode allows bi-directional RS-232 data communication with other ESTeem Model 195C/M’s. The
RS-232 data transmission will appear transparent to the connected devices as if a serial cable is connected between the two ports.
This mode will also be used in a multi-point serial network were all serial devices will need bi-directional communication (Figure
6).
Terminal Server Mode - This mode of operation translates RS-232 serial data into a network-oriented terminal protocol, such as
telnet or SSH. This mode would be selected if an interactive RS-232 session at remote locations is desired over the wireless
Ethernet link.
Baud Rate
Select the data rate of the RS-232 connection to match your serial device.

Revised: 1 Oct 13 6-5 EST P/N AA107-195CM
Flow Control
Select the type of data flow control used on the RS-232 connection. The ESTeem can support Hardware flow control (RTS/CTS
control lines) or Software Flow Control (XON/XOFF). Select None if no serial flow control is necessary.
Maximum Bridge Links for Multicast Packets
This value sets the maximum number of Ethernet bridge links that the multicast packets will be sent through when used in a multi-
point system. A multi-point serial network uses multicast packets (UDP) to send the data to more than one remote ESTeem. You
want to limit the number of network bridge links that these UDP packets will be passed through to make the network more
efficient.
If you are using multiple ESTeem repeater links to send the serial data to remote locations, the value for the maximum bridge link
needs to be increased to a number greater than the longest repeater chain. For example, if you are using four repeater (peer) links
to send the serial data between two or more sites the number will need to be five (5) or greater (Figure 4).
Destination IP Address
The ESTeem configured for the correct destination IP and port number will send and receive the serial data from another modem.
Set the destination IP address for the ESTeem where the serial data will be sent. If sending to more than one ESTeem (Multipoint)
set to a multicast address (i.e 224.0.0.1).
Note: If you are using the ESTeem 195C/M in a multipoint application (multicast), you must have default Gateway configured
in the ESTeem set to the IP address of the Root Bridge modem.
Serial IP Port Number
The ESTeem configured for the correct destination IP and port number will send and receive the serial data from another modem.
Set the IP port numbers to match where the serial data will be sent. The serial data will not be sent if both the IP address and port
number is not correct.
Maximum Packet Size
This number represents the maximum size of the serial data packet in bytes. If the number of bytes of data in the serial port buffer
exceeds the maximum packet size before the timer or delimiter character is reached, the ESTeem will send forward the serial
packet. For example, if the maximum packet size is set to a value of 100, when the serial port receives 100 bytes the data will be
sent through the wireless connection.
Number of Milliseconds for Packetization
This number represents the time the ESTeem will hold data in the serial data buffer before sending to the remote ESTeem. This
feature is generally used if the serial data does not have a consistent packet length or delimiter character. For example, if the
number of milliseconds is set to a value of 10 the ESTeem will monitor the incoming serial data stream and any break in characters
longer than 10 milliseconds will cause the data will be sent through the wireless connection.
Delimiter Characters
Enabling and specifying a delimiter character will transmit the data in the serial buffer when the delimiter character is recognized
in the serial data stream. There are two unique delimiter characters that can be configured and enabled independently.
Terminal Server Control Lines
Enabling this feature will allow the ESTeem in the Terminal Server mode to read and generate modem control lines to the
connected device.

REPEATING FEATURES
Revised: 1 Oct 13 7-1 EST P/N AA107-195CM
When programmed in any of the three Access Point (AP) Repeater Modes, the Model 195C/M will create a wireless network with
other Model 195C/M units in radio range that are programmed in the AP Repeater Peer table during setup. This feature adds the
increased functionality of repeaters to the typical Ethernet Bridge configuration.
ESTEEM MESH NETWORK
One of the most powerful features of the AP Repeater Mode is the ability to input multiple communication routes and designate
the priority for each of these routes to create a wireless Mesh network. The ESTeem Model 195C/M will automatically change
communication routes in the network if a route has failed. The new route will be based upon the priority level set during
configuration. This wireless Meshing technology allows the RF network to “self-heal” if any of the communication paths fail.
The routing priority is manually set during the configuration of the 195C/M. A manual path configuration is far superior to
standard “self-discovery” networks, because you have direct control over the best RF paths and can easily identify any failed
routes for easy troubleshooting. For example, Figure 1 shows a typical wireless Ethernet system used in the Water/Waste Water
Industry. The problem with a standard “self-discovery” Mesh network is the selection of routes. Notice that the communication
between the Water Plant (Site A) and Pump Site D has a marginal link, but it is the most direct route between the Ethernet devices.
This scenario poses the question, which path will the network select? The ESTeem Mesh Network takes out the guessing games
by allowing the user to select and prioritize all communication routes in the system. In our example we would want the primary
link to go through Tank B (Repeater) and use the direct link only if this primary link fails. The following sections will show how
this completed.

Configuration
The configuration of the repeater paths is completed during setup of the Access Point modes. All three Access Point modes
support repeating and Meshing features. The Mesh network configuration using the ESTeem Network Configuration (ENC)
Utility is shown in detail in Chapter 3 of this User’s Manual.
Figure 2: Repeater Configuration Example
You can also configure the Mesh networking directly through the web configuration setup (Chapter 5). Figure 2 shows an
example repeater peer table from the setup menus. For an ESTeem 195C/M to communicate with another ESTeem 195C/M,
select Yes must at Enable Repeater Capability. Next, the Wireless LAN (WLAN) MAC address of each Model 195C/M that will
have direct communications must be added to the Repeater Peer List. Finally, enabling the link allows the corresponding 195C/M
to be included in the communication routing. Mobile clients do not require input in the repeater peer table. If multiple Mesh routes
are configured, you will also need to set the values for Priority and Path Costs (explained in Spanning Tree below). For multiple
examples of repeater configurations, please refer to Chapter 3 of this user’s manual.

RAPID SPANNING TREE PROTOCOL (RSTP)
The ESTeem Model 195C/M uses Rapid Spanning Tree Protocol (RSTP - IEEE 802.1d) to determine the radio routing structure of
the wireless network. This RSTP functions the same as standard Spanning Tree Protocol (STP) listed below, but the network
recovery is three times faster. If the 195C/M is used in a network that has any older STP only modems, the entire network will be
STP.
SPANNING TREE PROTOCOL (STP)
The ESTeem Model 195C/M uses standard Ethernet Spanning Tree Protocol (STP) or Rapid Spanning Tree Protocol (RSTP) to
determine the radio routing structure of the wireless network. The primary purpose of STP/RSTP is to make sure that “network
loops” are not created. A network loop is having two communication paths to the same destination where the remote device would
receive the same data multiple times. If there were no way to control the data flow, this data would be constantly passed around
this loop causing a “packet storm” that would shut down the entire network. The Spanning Tree Protocol will block all these
redundant links.
Figure 3: Programming Example #1 Diagram
The STP operation begins by determining which Ethernet device on the network will be the Root Bridge. All Ethernet networks
have a Root Bridge that is selected by the lowest MAC address. All path costs are evaluated against this Root Bridge device to
