Ref Sync Modes

Hi,
I have an M48 and am trying to work out what the differences are in certain Ref Sync modes.
Some types have a range, eg 1-4, 11-14, 71-74 etc.
So, what are types 1,2,3,4 and 11,12,13,14 ?
Is this to do with the combination of ref and sync sensor type? eg If the Ref is a hall sensor and the sync is a mag sensor and one is a rise type and one is a fall type?
I can't find a table explaining this in the help, just some odd mentions of it in this forum.
Would help, as I'm experimenting with different combinations at the moment.
Thanks
Paul
