The benefit is for debugging purposes. If 1 DZ-2500 has problems (fails, gets its brain scrambled, etc.), all the others on that DZ-2001 switch bus stop working. If you've got 30 switches on that switch bus, you've got to find the malfunctioning culprit. Lionel suggests their break-out box, but at 1 / DZ-2500 and an MSRP of $25.00, that gets out of control really fast.
