Operation 1-3

SDI-12 Connections

To connect the SDI-12 data logger, slide the cable through the Hubble connector until enough wires
are exposed to make the proper connections to the screw terminals. Tighten the Hubble connector
hand tight to make a secure seal around the cable. Connect the wires to the terminal block as
labeled. Make sure no bare wires are touching the PC board or any components on it.
