Autoip; Device Installer; Channel 1 Configuration - GridConnect NET485 Manual

3.3.4 AutoIP

The unit ships with a default IP address of 0.0.0.0, which automatically enables Auto IP within the unit.
AutoIP is an alternative to DHCP that allows hosts to automatically obtain an IP address in smaller networks
that may not have a DHCP server. A range of IP addresses (from 169.254.0.1 to 169.254.255.1) has been
explicitly reserved for AutoIP-enabled devices. The range of Auto IP addresses is not to be used over the
Internet.
If your unit cannot find a DHCP server, and you have not manually assigned an IP address to it, the unit
automatically selects an address from the AutoIP reserved range. Then, your unit sends out a (ARP) request
to other nodes on the same network to see whether the selected address is being used.
If the selected add
If another device is using the selected IP address, the unit selects another address from the AutoIP
range and reboots. After reboot, the unit sends out another ARP request to see if the selected
address is in use, and so on.
AutoIP is not intended to replace DHCP. The unit will continue to look for a DHCP server on the network.
If a DHCP server is found, the unit will switch to the DHCP server-provided address and reboot.
Note: If a DHCP server is found, but it denies the request for an IP address, the unit does not attach to the network, but
waits and retries.
AutoIP can be disabled by setting the unit's IP address to 0.0.1.0. This setting enables DHCP but disables
AutoIP.

3.4 Device Installer

Device Installer is a Windows-based utility for configuring embedded device servers found in products such
as the NET232, NET232jr and NET485 Serial to Ethernet adapters. Device Installer supports several
functions such as setting network parameters, pinging a network device, and changing baud rate. The first
operation you must do is to locate the device on your network and assign the device a fixed IP address. Once
the unit has a fixed IP address, you can use several methods to setup the unit for your specific application.
Please locate and read the Device Installer User Guide found on the product CD. The manual can be read
by clicking the Device Installer Manual button on the software page of the product CD. You can also
browse the CD to find the manual. Locate the doc folder and double-click on DeviceInstaller_UG.pdf.
Device Installer is used to configure many different types of Ethernet devices. There are some important differences
when configuring a NET485.
