Verify Communications
After powering up and binding the Gateway and its Nodes, verify all devices are communicating properly. Verify LED 1 is green. Until
communication is established with the Gateway, the Node’s LED 2 flashes red. When communication is established, the Node’s LED 1
flashes green.
A Node will not sample its inputs until it is communicating with the Gateway to which it is bound.

For Gateway and Ethernet Bridge systems, active Modbus communication refers to the communication between the Gateway and the
Ethernet Bridge. For GatewayPro systems, the Modbus communication LEDs refer to the communication internal to the Gateway Pro.
For Gateway only systems, the Modbus communication LEDs refer to the communication between the Gateway and its host system (if
applicable).
When testing the Gateway and Node, verify all radios and antennas are at least two meters apart or the communications may fail.
