Address F is not available as it is the broadcast address. Setting this address will result in the SDM-SIO2R having
an address of 0 rather than F.
6.2 Connection and wiring
SDM-SIO2R connections to the data logger are made via the Input connector. Strip wires 7 to
9 mm and twist. Open the clamp by inserting a small screwdriver into the small hole and prying
away from the clamp. Insert the wire. Release the clamp and verify the clamp grips the wire rather
than the plastic insulation. See
