3.4 Methods of Assigning the IP Address

The unit's IP address must be configured before a network connection is available. You have several options
for assigning an IP to your unit, however, we recommend
Method Description

DHCP

A DHCP server automatically assigns the IP address and network settings. See
on page 3-5.
Device You manually assign the IP address using a Graphical User Interface on a PC
attached to the network.
Installer
See
Telnet You manually assign the IP address and other network settings at a command prompt
using a UNIX or Windows-based system. Only one person at a time can be logged
into the configuration port (port 9999). This eliminates the possibility of several people
simultaneously attempting to configure the unit. See
page
AutoIP This automatic method is appropriate when you have a small group of hosts rather
than a large network. This method allows the hosts to negotiate with each other and
assign addresses, in effect creating a small network. See
Serial Port You initially configure the unit through a serial connection.
Login
See
Web Manager
Through a web interface, configure the NET232 and its settings using the Web-Manager.
See
These methods are described in the remaining sections of this chapter.

3.4.1 Hardware Address

You need to know the unit's hardware address (also known as MAC address), which is on the manufacturers
ID label on the bottom of the unit. It is in the format: 00-20-4a-XX-XX-XX, where the XXs are unique
numbers assigned to the product.
Hardware Address: 00-20-4a- ____ - ____ - ____

3.4.2 IP Address

Your NET232/USB must have a unique IP address on your network. The systems administrator generally
provides the IP address and corresponding subnet mask and gateway. The IP address must be within a valid
range, unique to your network, and in the same subnet as your PC.
IP Address: _____ _____ _____ _____
Subnet Mask: _____ _____ _____ _____
Gateway: _____ _____ _____ _____
3.4.3 DHCP
The unit ships with a default IP address of 0.0.0.0, which automatically enables DHCP.
Provided a DHCP server exists on the network, it will provide the unit with an IP address, gateway address,
and subnet mask when the unit boots up.
You can use the Device Installer software to search the network for the IP address your unit has been
assigned by the DHCP server and add it to the managed list. See
