BEFORE YOU BEGIN

Thank you and congratulations on your purchase of the ESTeem

Model 195Es Wireless Ethernet Radio Modem! This manual was

written to help both the first time and advanced user of the 195Es

configure the radio modem for your application. If this your first

time configuring the 195Es and you would like to get going as

soon as possible, we recommend using the 195Es 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 195Es is a very versatile wireless networking device for both serial and Ethernet applications. 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

• Serial port requirements for the attached device

If you are unfamiliar with any of the above networking concepts, you may need to contact your network administrator for

assistance.

MODEL 195Es OVERVIEW

The ESTeem Model 195Es is a wireless LAN

transceiver that can be used to build a Wireless

Local Area Network (WLAN) for line-of-sight

distances to 10 miles at an RF data rate of 200

Kbps. The Model 195Es 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-

CHAPTER 1 INTRODUCTION MODEL 195Es CONFIGURATION MODES The Model 195Es 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 195Es is configured as an Access Point it will provide a wireless bridge between hardwired Local Area Network (LAN) networks or individual devices and simultaneously create a wireless canopy for the Model 195Es modems in client mode.

CHAPTER 1 INTRODUCTION 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 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.
