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 an 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. The 195Eg can provide RF data
rates up to 54 Mbps and can have an optional
serial port for legacy RS-232 devices. 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
