not those specific example, no. but have just gone through an exercise to connect up a similarly mixed bag of kit.
the key proved to be checking the manual for each one, and reducing the nmea sentences sent out to the minimum needed. you see nmea sentences overlap in the info they contain, and particulary if you are also using seatalk, you get a conflict where one over rides the other.
so carefully check which sentences the autohel needs, and then cut the gps back to those alone plus the position one that the dsc needs.
you can find out which sentence is which from the nmea website.

Should be fairly straightforwards.
Of the 3, I imagine the GPS is the only one that can output GPS data, the other two just receive it. So you need to connect the "data out" from the GPS to the "data in" on both the ST100 and DSC.
Use either shielded cable or UTP (unshielded twisted pair). If using shielded then connect the screen to -ve at the sender end.
