The DJM-1000 doesn't support ProDJ Link; that was a MIDI connection (for a whopping SIX MIDI control points!). It had fader-start, but unfortunately that was removed from the players when the CDJ-2000 came out with ProDJ Link (which transmitted that data).
The EFX link was a proprietary connection to create a send/return using just one cable (it was awesome, but only ever for that one product). :(
