In addition, you can force a rescan of the Modbus Network. This will cause the Gateway to detect any
new devices added to the serial network. Set the baud rate of the network to 9600 or 19200-baud. The
value selected must match the value in all of the controllers on the serial network. Up to 16 controllers
may be scanned by the Gateway using the built-in HTTP server. Set a start address to the lowest
address number of the controller on the serial network. Set an end address to the highest address
number of the controller on the serial network.
As an example, you have your first controller set to address 23 and the last one set to 35. Set Start
Address to 23 and End Address to 35. You can limit the number of controllers accessed by the
Gateway by setting the Maximum Nodes value to less than 16.
Lastly, this page provides links to Network Setup, Email Setup, Clock Setup, Network Statistics, and
