Dynamic and static IP addressing
An IP address can be assigned to a device or a computer automatically by a DHCP
server (dynamic IP address), or manually by modifying the properties of your LAN
adapter (static IP address). As shown in Table 2-2 Innotech devices are factory
configured for either dynamic or static IP address assignment.
You must assign a static IP address to your Innotech device(s) to avoid any
communication problems. One such problem with dynamic IP addressing is IP address
conflicts, where two device(s) get assigned the same IP address. Another problem that
may occur with dynamic IP addressing is that your Innotech device(s) may get assigned
a different IP address each time the device reboots or restarts. Both of these problems
can result in your device(s) not communicating correctly on your network or with the
iComm software.
It is also important to know that when a device that is factory configured for dynamic IP
address assignment is unable to reach the LAN DHCP server, it will automatically be
assigned a special IP address in the range of 169.168.xxx.xxx by the Windows service
called APIPA (Automatic Private IP addressing).
Therefore when connecting the Genesis, MAXIM III, MAXIM 1010, or a CONV-E to
a LAN without a DHCP server, or when connecting directly to your computer, please
keep in mind that these devices may be automatically assigned the 169.168.xxx.xxx IP
address by the APIPA service. This information is important and may be helpful when
diagnosing communication problems with your Innotech device(s).
