Device Installer
NET485 User Guide 3-1
3. Getting Started
This chapter covers the required steps to get the NET485 Serial to Ethernet adapter on-line and working.
The NET485 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 3-2.
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. Make sure
the unit is configured for RS422/485, the baud rate matches your device, and the wiring matches the
diagrams shown in previous sections.
3.2 Physically Connecting the Unit
1. Connect an active network Ethernet cable to the NET485’s Ethernet port.
