De Vere Transtab pin-out for connecting RH Stopclock.

I want to connect a RH Designs stopclock to a De Vere 504 Transtab supply. I remember reading it can be done without the RH specific plug if you have the pin out details. Does anyone here have the correct pin out details available ?

John Boyce at Odyssey Sales is probably the best person to contact regarding the pinout - that said, I can't see it being terribly complicated to trace the circuit if needed.
