HITEC PRISM TROUBLE - PRISM 7 QUERY

[shamos]

I am having trouble getting the interface working with a Hitec Prism 7. When i turn the transmitter on all i get is "Signal Connected" but non of the channels bars will move, I am not sure which pins i should be using in the Din plug to my Transmitter. Can anyone shed some light on this subject for me ? Thankyou.
