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 Device Installer on page 3-6.
Method Description
DHCP
A DHCP server automatically assigns the IP address and network settings. See DHCP
on page 3-5.
Device
Installer
You manually assign the IP address using a Graphical User Interface on a PC
attached to the network.
See
Device Installer on page 3-6.
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
Using a Telnet Connection on
page 3-15.
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 AutoIP on page 3-6.
Serial Port
Login
You initially configure the unit through a serial connection.
See
Configuration Using Telnet or Serial Port on page 3-15.
Web Manager Through a web interface, configure the NET232 and its settings using the Web-Manager.
See
Configuration Using Web Manager on page 3-7.
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 Device Installer later in this chapter.
