It looks like the sled is wired incorrectly. on mine instead of pins 8 wired to serial pin 2, and 9 to 3, it was the other way round (8 -> 3 and 9 -> 2)
This is a bit worrying as i have another sled which is the same. So it may be a batch (and may be worth adding to the FAQ).
After switching these round i now get output in hyperterminal. However it does not accept any keystrokes. And logo editor find the player, but complains it cannot find manufacturer ID.
So i guess something still isnt right.
My pinouts are as follows (they seem to match the ones on the FAQ except for P2->P4?):
Harness-------Serial
P2---------------P4
P8---------------P2 (was P3)
P9---------------P3 (was P2)
P10-------------P8
P11-------------P1
P13-------------P5
Any help would really be appreciated. This is driving me nuts!
