The Price Computational Scale Interface is available on AUX 1. See Third-Party Scale to enable or disable Third-Party Scale functionality.
Third Party Scale configurations only function on Zebra Bioptic systems sold without a scale (model numbers starting with MP7200-). Zebra Bioptic systems sold with a scale (model numbers starting with MP7201-, MP7202-, MP7203-, MP7204-) do not support Third Party Scale configurations.
