Thanks Dave,

Hmmm Ciseco documentation. Good overall, but very confused descriptions with various devices being refered back to each other. Lots of back and forth. It strikes me of someone who knows their products, but forgot to ask someone who doesn't know to look at the site.

I was reluctant to split the board as it's a nice fit in box but it's now getting too close to deadline, so I'll try the cable route.
