Multiple SDI-12 Sensors
Because each sensor in a multiple SDI-12 system should share the same: SDI-12, GND, and
BAT, it is recommended that those three pins be brought to a junction box where each wire is in
a “multi-drop” network. This simply means that all the SDI-12 wires are connected, all the +12V
wires are connected, and all the GND wires are connected together and wired to the appropriate
pins on the iSIC.
