12. Web Browsers and Proxy Servers

If you are working on a corporate LAN that uses a proxy server for Internet web browsing, you will
need to exclude the IP Address of your SBL2e in your web browser‟s proxy server
settings/preferences. Otherwise, an attempt to connect to a web page on the LAN will fail because
the proxy server will attempt to route the request outside the LAN. For most web browsers, this can
be accomplished in the advanced settings for the proxy server configuration. Set the Network Mask
for your host computer‟s network adapter and your SBL2e to 255.255.255.0.

13. Testing with a Telnet Connection

A quick way to test the functionality of your Serial-to-Ethernet connection is with the Telnet
program and an Serial Terminal Program, such as the NetBurner MTTTY program included on the
CD-ROM. To run this test, configure your system as one of the two examples shown below. The
Red Ethernet cable is a cross-wired cable that can be used for a direct connection without a network
hub/switch. The Blue Ethernet cable is a standard straight-through Ethernet cable that should be
used if you have a network hub/switch.
The objective of this example is to use a single host computer running telnet and a serial terminal
program to send data in either direction. When you type text in the telnet window, it should appear
in the serial terminal window and visa versa.
In the following example, an IP Address of 10.1.1.79 is be used for the SBL2e. Replace this IP
address with the actual IP Address of your SBL2e.
