    Hello I am slightly confused by some of the data field terminology used in Wyg and why certain errors are thrown up. I live in the UK and work on live shows and concerts so maybe some of the terminology is different. I use WYSIWYG report for producing lighting plots.

    Spot - Am I correct in thinking that ‘Spot’ is what I would call the ‘fixture number’ of a light? Normally (but not always) an intelligent light, Up until now I've been using 'unit' for this. If so what is the difference between spot and unit?

    Channel - The manual suggests Channel is something to do with a lights' DMX address? If so how does this differ from 'patch'? I find ‘Patch’ a strange term when referring to a light. In my world consoles are patched, dimmers are patched but lights are ‘addressed’.

    Patches > Circuit error
    Why would it be a problem if a light with a different DMX address was on the same circuit? Surely all the lights in the rig will have a unique DMX address (on each universe) however it is highly likely 2 lights may be paired on a circuit.

    Channel identifies a conventional fixture
    Spot identifies a multi-parameter fixture
    Unit identifies which fixture on a bar (from house left to right or from stage left to right)
    So it is easy to explain that the sixth light should get a L201 gel.
    Patch specifies the dmx adress
    Any channel or spot can have a dmx adress / patch number assigned.
