6 OPERATION
6.1 Power up the device
Apply power to the device. Ensure that the power supply used complies with the specifications provided
in Section 4.2. 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.
6.2 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 .

6.3 Connecting to the EZ Gateway
6.3.1 Using the Toolbox application to discover and connect to the EZ Gateway:
Install the Toolbox application from the USB drive or get it from our 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 GUI
Please 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. See Section 6.3.2

Modbus to BACnet Start-up Guide
Page 11 of 25
6.3.2 Using a Web Browser directly
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.
6.4 Set IP Address of the EZ Gateway
6.4.1 Using the Toolbox Application to set the IP address:
From the Toolbox main page, click on the setup icon (the gear picture).
Figure 6 –Main page

Modbus to BACnet Start-up Guide
Page 12 of 25
Select Network Settings.
Modify the IP address (N1 IP address field) of the EZ Gateway Ethernet port.
If necessary, change the Netmask (N1 Netmask field).
Type in a new Subnet Mask
If necessary, change the IP Gateway (Default Gateway field)
Type in a new IP Gateway
Note: If the EZ Gateway is connected to a router, the IP Gateway of the EZ Gateway should
be set to the IP address of the router that it is connected to.
Click Update IP Settings, then click on the Change and Restart to restart the Gateway and
activate the new IP address. Note that if the GUI was open in a browser, the browser will need
to be pointed to the new IP address of the EZ Gateway before the GUI will be accessible
again.
