3. Getting Started
This chapter covers the required steps to get the NET232/USB Serial to Ethernet adapter on-line and
working. The NET232/USB contains a complete device server that controls the network communications.
Note: See the Quick Start Guide for a quick setup procedure.
3.1 Quick Rundown
For the unit to operate correctly on a network, it must have a unique IP address on the network. There are
three basic methods for logging into the device server and assigning the IP address:
•
DHCP
: By default, Dynamic Host Configuration Protocol (DHCP) is enabled on the device server.
DHCP allows a DHCP server to automatically assign an IP address to the device server. If you use
DHCP, the device server is assigned a new IP address each time it boots.
•
Device Installer
: You can manually assign the IP address using a graphical user interface (GUI) on
a PC attached to a network.
•
Serial Port Login
: With this method, you connect a terminal or a PC running a terminal emulation
program to the unit’s serial port.
All of the methods for assigning an IP address will be discussed in
Methods of Assigning the IP Address
on
page 3-5.
It is important to consider the following points before logging into and configuring the device server:
•
The device server’s IP address must be configured before a network connection is available.
•
Only one person at a time may be logged into the network port. This eliminates the possibility of
several people simultaneously attempting to configure the device server.
•
Network port logins can be disabled. The system manager will not be able to access the unit. This
port can also be password protected.
For the unit to operate correctly with your device, you must configure the serial port properties. The
methods for configuring the NET232 to work with your equipment will be discussed in
Configuration Using
Web Manager
on page 3-7 and in
Configuration Using Telnet or Serial Port
on page 3-15.
3.2 Physically Connecting the Unit
1. NET232-DTE: Use a null modem adapter to connect the serial cable to a COM port on your PC.
OR
NET232-DCE: Connect the serial cable to a COM port on your PC.
OR
NETUSB: Connect the USB cable to USB port on your PC.
2. Connect an Ethernet cable to the NET232/USB’s Ethernet port.
3. Supply power to your unit using the power supply that was included in the packaging. NETUSB units
receive power from the USB port.
Note: If you are using a NET232 unit with a Phoenix Connector, the input power is +9 to +24VDC.
