BEFORE YOU BEGIN
Thank you and congratulations on your purchase of the ESTeem
Model 195E Wireless Ethernet Radio Modem! This manual was
written to help both the first time and advanced user of the 195E to
configure the wireless modem for your application. If this is your
first time configuring the 195E 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 195E series wireless modems are very sophisticated
networking devices. 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.
