Changing the Network Settings
The BACnet Communication Module is assigned a factory default IP address and Subnet Mask.
These are only temporary but are required so that you know where to access the BACnet
Communication Module in order to change network parameters. The BACnet Communication
Module is configured using a minimal HTTP server that is accessed using Internet Explorer®.
Required Tools
You need the following tools to configure the BACnet Communication Module for network
operation:
• PC with Ethernet card and TCP/IP protocol.
• Internet Explorer browser.
• Ethernet Cable (Either an Ethernet crossover cable for direct connection or a standard Ethernet
cable for connecting through a hub.)
Procedure
The procedure for changing the network settings varies depending the operating system in your
computer.
You must access the HTTP Interface page at its IP address. In order to access the configuration page,
your computer must be on the same subnet as the BACnet Communication Module. Doing so will
allow you to:
1. Change the network settings on your computer and options in Internet Explorer.
2. Access the HTTP Interface page to change the BACnet Communication Module parameters.
3. Change the network settings of your computer and Internet Explorer options back to the way they
were before the configuration process.
Details regarding each of these items are described below.
To Change the IP address in the BACnet Communication Module:
Note: You can only connect to the BACnet Communication Module via the Ethernet port. To
install the BACnet Communication Module using an MS/TP (RS-485) network, you must
connect via an Ethernet cable directly to the BACnet Communication Module, then change
the settings for the MS/TP network, and finally install the BACnet Communication Module
in the MS/TP network.
1. Connect to the BACnet Communication Module via the Ethernet port.
2. Request the Subnet Mask of the network for the BACnet Communication Module from the
network administrator.
3. Request an IP address for the BACnet Communication Module from the network administrator.
4. Change the network settings on your computer to access the BACnet Communication Module.
Use the appropriate procedure below for your operating system.
5. Open the browser on your computer.
6. In the Internet Explorer, go to Tools/Internet Options/Connections/LAN Settings.
a. Note the selections for future reference.
b. Verify that Automatically Detect Settings, Use Automatic Configuration Script, and Use a
Proxy Server for Your LAN are not selected.
Note: Verify that these settings are disabled to confirm that the changes you make to the
BACnet Communication Module with the browser take effect.
7. Type http://172.16.5.8/ in the Address box of the browser and press the Enter key to access the
BACnet Communication Module.
