5 OPERATION
5.1 Power up the Device
Apply power to the device. Ensure that the power supply used complies with the specifications provided
in Section Appendix B.1. Ensure that the cable is grounded using the “Frame GND” terminal. The EZ
Gateway requires a power supply that provides 9-30VDC or 12-24VAC.
5.2 Connect the PC to the EZ Gateway over the Ethernet Port
Connect an Ethernet cable between the PC and EZ Gateway or connect the EZ Gateway and the
PC to the Hub/switch using a straight CAT5 cable.
The Default IP Address of the EZ Gateway is 192.168.2.101, Subnet Mask is 255.255.255.0.
Virus protection and firewall software should temporarily be disabled if connection problems are
experienced.

5.3 Connecting to the EZ Gateway
5.3.1 Using the Toolbox Application to Discover and Connect to the EZ Gateway
Install the Toolbox application from the USB drive or get it from the Sierra Monitor website.
http://www.sierramonitor.com/customer-care/resource-center?filters=software-downloads
Use the Toolbox application to find the EZ Gateway, and launch the Web Configurator GUI.
NOTE: If the connect button is greyed out, the EZ Gateway’s IP Address must be set to be on the same
network as the PC. (Section 5.3.2)
5.3.2 Using Web Configurator GUI
Open a web browser and connect to the EZ Gateway’s Default IP Address. The Default IP
Address of the BACnet Router is 192.168.2.101, Subnet Mask is 255.255.255.0.
If the PC and the EZ Gateway are on different IP Networks, assign a Static IP Address to the
PC on the 192.168.2.X network.
