1. XML to BACnet IP Gateway Description
The XML to BACnet IP Gateway connects to an Ethernet enabled device that responds to commands
XML commands. This implementation of the XML to BACnet IP Gateway communicates using specific
XML commands and URLs to get data from and change parameters on a Functional Devices Rib Wi-Fi
device. The Gateway can be configured to connect to multiple Rib devices.
The Gateway connects to the Rib device, reads data, and stores it internally. When a remote system
requests data, the data is served in a form that is appropriate to the requesting protocol. In this case
the protocol is BACnet IP.
The Gateway can also receive BACnet IP Write Property requests to certain points that will cause the
Gateway to send XML write commands to the end Rib device.
This manual contains additional information about how the Gateway operates as well as instructions on
how to setup the connections to the Gateway and how to configure and read data from the Gateway.
The following is a brief description of the sections covered in this manual.
2. Connections
This section contains information about how to connect to the Gateway. It includes block diagrams and
any wiring diagrams that are needed.
3. Setting up the Gateway
This section describes how to connect to the Gateway initially and how to set the IP Address
4. Configuring the Gateway
This section has instructions and images of how to configure the Gateway through the web page
interface.
5. Reading the Data
This section contains example of the Rib data that is stored on the Gateway and how to read the Reports
Page
6. Commanding the Rib Device
This section describes how the Gateway communicates with the Rib Device to poll for data and to send
commands.

Port 1
This port is setup a RS232 port and is NOT used by the Gateway.
Ethernet Port
This port is used by the TCP/IP and UDP drivers of the Gateway. Default port for accessing the internal
web server of the Gateway is 80.
2.3 Limitations and Best Practices
Maximum Number of Rib Devices per Gateway
Using the configuration screen, users can add up to 25 Rib devices.
It is possible to add more devices, but will require a custom configuration. However, as more and more
devices are added to a configuration, the Gateway will have more performance issues as there are more
devices to poll from and data to decode.
Please contact sales if you would like to use a custom configuration consisting of more than 25 devices.

3. Setting up the Gateway
This section contains information and instructions on what to do when connecting to the Gateway for
the first time.
3.1 Determining the IP Address
Before connecting to the Gateway, you will need to determine the IP Address of the Gateway. By
default, the Gateway is assigned a Static IP Address of 192.168.1.113 when it is shipped.
To find the IP Address, look on the back of the Gateway. There should be a business card attached to
the back of the Gateway that has the IP Address and Reference #. See below for an example
Image 3.1 –Business Card attached to back of CAS Gateway
Take note of the Ref# as this will be used by the support team to pull up additional information about
the project.
The IP Address that is written on the business card should be the Static IP Address assigned to the
Gateway.

3.2 Connecting to the Gateway
To Change the IP Address of the Gateway (Section 3.3) or to Configure the Gateway (Section 4), you use
a PC and connect to the Gateway using an Ethernet cable. (The Ethernet cable should have been
provided with the Gateway when shipped).
Before connecting the Ethernet cable, set your computer’s IP Address to be similar to the Gateway’s IP
Address.
For Example, a Gateway is assigned the following IP Address by default:
IP Address –192.168.1.113
Netmask –255.255.255.0
Gateway –192.168.1.1
So set your computer to the following:
IP Address –192.168.1.100
Netmask –255.255.255.0
Gateway –192.168.1.1
After setting the IP Address on the computer, connect the Ethernet cable to the computer and to the
Gateway.

3.3 Changing the IP Address
To change the IP Address of the Gateway, you will need to use the IP Setup Tool. The tool can be found
on the blue USB stick that should have come with the Gateway.
Run the IP Setup Tool application and you will see the following window open:
Image 3.3 –IP Setup Tool
The ‘Select a Unit’ section will have the Gateway you purchased listed with the assigned IP Address.
To change the IP Address, change the fields list on the left side under the ‘NDK Settings’
Note: Please do NOT change the Baudrate value.
Once you have changed all of the settings, click the ‘Set’ button in the middle of the window. The
Gateway will automatically reboot to assign the new IP Address.
After you have finished changing the IP Address, you may not see the device in the ‘Select a Unit’
anymore when pressing the ‘Search Again’ button. This is because your computer is now on another
subnet than the Gateway.
Change your computer back to the original address and you should be able to see the Gateway again
when you press the ‘Search Again’ button.
Now you can add the Gateway to the site network. Note down the new IP Address so that others will
know the assigned IP Address.
