Question
Generally, Soil Probes are connected to the C3 or Solo via the SDI-12 port, of which there is only one. So how can I connect more than one probe?
Answer
You can connect multiple SDI-12 devices powering each additional device from a different output.
Overview
Connect all wires from your first sensor to the C3's SDI-12 port as you would normally.
For the second sensor, connect the ground and data cables to the C3's SDI-12 port in the normal way as well.
When it comes to the second sensor's power cable however (usually, but not always, red or brown in colour), instead connect it to Output 1.
Make sure you update the configuration in Manage Equipment.
