Quick update..
Found the problem
when i connected the other hdr i used a "T" piece to t out then had freezing probs
( hence trying the in and out on the same card, (not right))
but when i connected back it was freezing still at times but i had left the T piece in and just connected the one lead in that.
still freezing
Just connected as the Wordclock Setup page from pete above( which is how i had tried it using a T) and again still freezing only this time noticed the no clock astrix was still flashing on the d8b.
Problem was a bad T piece, the middle male pin (bottom of the t ) was loose, checked it with a meter and yep intermittent connection, so changed it for another old one i had
and perfect, after all that.
again cheers all
