LED Behavior for the Nodes
After powering up and binding the Gateway and its Nodes, verify all devices are communicating properly. A Node will not sample its
inputs until it is communicating with its Gateway. When testing communication between the Gateway and Node, all radios and antennas
should be at least two meters apart or the communications may fail.

Modbus Register Table
When your wireless network does not include a host system, the four input/eight output Node must be mapped to the eight input/four
output Gateway.

The lower eight bits of the 16-bit unsigned register
represent each of the eight digital outputs. There-
fore, if all outputs are OFF (0) the register con-
tains 0x0000; if all outputs are ON (1) the register
contains 0x00FF (255).
