I have both RC and Laptimer on the same laptop connected to the parallel port with the same lead and both work fine so I assume the wiring is the same for both. Mind you I don't use relays or track call buttons etc so that may differ. No wiring diagram though as a friend made the lead up for me over 10 years ago.

The track configuration section of RC is a live feed so it is easy enough to check if everything is OK.
