Setting up Your Computer’s IP Address
All computers must have a 10M or 100M Ethernet adapter and TCP/IP installed.
Windows 95/98/Me/NT/2000/XP/Vista, Macintosh OS 7 and later operating systems and all versions
of UNIX/LINUX include the software components you need to install and use TCP/IP on your
computer. Windows 3.1 requires the purchase of a third-party TCP/IP application package.
TCP/IP should already be installed on computers using Windows NT/2000/XP, Macintosh OS 7 and
later operating systems.
After the appropriate TCP/IP components are installed, configure the TCP/IP settings in order to
"communicate" with your network.
If you manually assign IP information instead of using dynamic assignment, make sure that your
computers have IP addresses that place them in the same subnet as the AMG1302/AMG1202-
TSeries’s LAN port.
