Anton Bauer SO-XLR Gold Mount to 4-Pin XLR Adapter

The SO-XLR adapts any Gold Mount to accept a standard 4-pin XLR connector, which turns a battery shoe into an input rather than only an output.

That matters when a camera is being run from a secondary source, a block battery or a mains supply, and the operator still wants the PowerTap connectors on the Gold Mount working for accessories at the same time. Without it, powering from XLR usually means giving up the P-Taps.
