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.

Supported RTD Types
The RTD Node supports up to four 3-wire RTD inputs by default. Additional types are available with configuration.

Range °F Range °C
Pt100 (DIN 0.00385) -328 to 900 °F -200 to 482 °C
Cu 10 Ohm (alpha = 0.00427) -328 to 500 °F -200 to 260 °C
* For the copper RTD, the best accuracy is when measuring between −50 to +150 °C (−58 to +302 °F). Below this range, expect errors
approaching 3% of reading. Above this range, expect errors approaching 0.5% of reading.

In high resolution mode, the temperature = (Modbus register value) ÷ 20. In low resolution mode, the temperature is (Modbus register
value) ÷ 2.
Temperature values are stored as signed values in the Modbus register. A 0 in the register is interpreted as 0°; and -32767 (65535
unsigned) in the register (0xFFFF) is interpreted as −1 ÷ 20 = −0.05° in high resolution mode and −1 ÷ 2 = −0.5° in low resolution mode.
