SDI
SDI inputs utilize the SDI-12 interface on the 8310. The SDI InputType requires several
properties to be configured:
SDIAddress
0-9,A-Z,a-z
SDICommmand
M,C,MC,CC,…
SDIParam
0..9
Solar
The Solar input type measures the voltage of the solar input. The measurement of the solar
input can be used to track the health of secondary power.
Reference
Reference inputs access data from other measurements. This allows for multi-level processing
on any output – such as an average of an average. The only configuration value for a reference
input is the selection of the measurement output you wish to use.
QuadSE
QUADSE inputs are special digital inputs compatible with quadrature shaft encoders. They
require the following values:
