    Can someone please confirm that the 503NMS slave mech doesn't draw power from the bus?
    So if im using a 5031NMML either by itself or with 3 slaves the load on the bus is always 18ma??
    As a separate question does anyone know why why the cbus load calculator app show four instances of the 5031NMML?
    Double clicking the entry shows the same specs for each.

    The slave mechanism does not draw any (extra) power from the bus. Any power used (to light LED indicators) would be included in the power for the master.

    I can't recall if the IR receiver version of the mech is still available. There would be two versions in the database of current draw. Not sure why 4x though

    Regarding question does anyone know why the cbus load calculator app show four instances of the 5031NMML.

    you may have entered 4 x instances of the 5031NMML, as their is no entry in project data base for 5031NMS
    If you want to enter for example a 3 key being 1 x 5031NMML and 2 x 5031NMS from data base to project then you add the unit type KEYE3 which still has the same Catalogue number of 5031NMML but it is basically a 3 key input.

    If you are adding from live network back to project as long as you have the 5031NMS attached to the 5031NMMS at the time of scanning, it will identify as the correct KEYE# number and be added correctly.

    I am assuming you refer to load calculator for network in toolkit, or are you referring to the very old standalone application? if the later , that has not been maintained for many years, and was always buggy we moved away from using that and reply on the what is built into SLCC and Toolkit at the network level.
