BEFORE YOU BEGIN
Thank you and congratulations on your purchase of the ESTeem
Model 195Ed Wireless Ethernet Radio Modem! This manual was
written to help both the first time and advanced user of the 195Ed
configure the radio modem for your application. If this your first
time configuring the 195Ed and you would like to get going as soon
as possible, we recommend using the 195Ed 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 195Ed 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.
