•
After setting your PC to be on the same subnet as the ProtoNode (Section 4.1), open a web browser on
your PC and enter the IP address of the ProtoNode; the default address is 192.168.1.24.
•
If the IP address of the ProtoNode has been changed by previous configuration, you will need to get the
assigned IP address from the network administrator.
•
The Web Configurator will be displayed as your landing page. (

)
•
Node_Offset field will be presented displaying the current value (default = 50,000).
•
Change the value of Node_Offset to establish the desired Device Instance values, and click SUBMIT.
o
Given that: Device Instance = Node_ MAC address
o
Then:
Node_Offset (required) = Device Instance (desired) – MAC address
For example:
o
Device 1 has a Modbus Address of 1
o
Device 2 has a Modbus Address of 2
o
Device 3 has a Modbus Address of 3
o
MAC address (Bank “A” DIP switches) = 11
o
Desired Device Instance for 1
st
device = 1,011
o
Node_Offset (required) = 1,011 – (MAC address) = 1,011 – 11 = 1,000
o
The Node_Offset value will be applied to all devices.
o
Device 1 Instance will then be = 1,000 + MAC address = 1,000 + 11 = 1,011
o
Device 2 Instance will then be = Previous Value + 1 = 1,011 + 1 = 1,012
o
Device 3 Instance will then be = Previous Value + 1 = 1,012 + 1 = 1,013
