Daisy chaining is usually connecting pieces of gear in series, from the output of one to the input of the next. It is not the same as side-chaining.
So if you have three,
out#1-in#2-out#2-in#3
and so on for however many units you have.
Example:
Say you have a separate mic pre, compressor, eq, and recorder, and you want to record your vocal with all of these. (Not the way you would probably do, it, but just for an example.)
You go out of the mic pre, into the comp, out of the comp, into the eq, out of the eq, into the recorder. These devices are daisy-chained together.
