10-30. Power, 10 to 30V dc power connection. (For internal battery mod-
els, do not use this connection.)
Ax+ and Ax-. Analog IN x. Analog inputs for devices requiring more than
one connection, such as thermocouples or RTDs. When there is no Ax-,
use Ax+ as an analog input.
BAT. Internal battery connection.
GND. Ground/dc common connection.

Thermocouple: When wiring the thermocouple, x is the same number. For ex-
ample, a thermocouple is wired to A1+ and A1-.
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 the Gateway to which it is bound. When testing communication between the Gateway and Node, all
radios and antennas should be at least two meters apart or the communications may fail. This table lists the LED behavior for the Node
models with two LEDs.
