ASR1 & ASR2 are kinda 'made up' terms to reflect that the [1] are the original files for units such as your 885 and 2x60/3790, and the later [2] are for 2xx5/3490/359x etc. Easy way to tell which is which is to look at the number of files or overall size, ASR1 will be smaller size and have less files than ASR2 as seen in kenta2's post above.
