Node Modbus Register: The Gateway uses the first 16 registers followed by each Node in the network, based on the Node address. For
Node 5, the starting Modbus registers are 1 + (Node# Ч 16) = 1 + (5 Ч 16) = 81, the ending register is 97.
Use one of Omega’s 44006 or 44031 families of 10kΩ thermistors.
The Battery Sense feature detects if the Node is being powered by the solar assembly, 10-30V dc, or by the DX81P6 6-Pack Battery
Supply Module. The sensor reads 5.0V for solar power, 4.0V for 10-30V dc power, and 3.6V when powered by the DX81P6.
