Rerurn to Romy the Cat's Site

Romy, I'm not sure we're talking about the same thing.

In your current setup, you are using the internal Lynx wordclock. In this case, the Lynx may well 'shut down' the external BNC wordclock cable. But that's not what I'm concerned with.

When you are slaving the Lynx to the Model Two, you will select 'external' for the 'Preferred Clock Source', attach a BNC cable between the two units and set the Model Two to 'MASTER'. Now, what I'm saying is that you need to make sure that the BNC input to the Lynx is properly terminated @ 75 Ohms. It may well be that the Lynx already does this automatically (the Weiss AFI1 does, but the Fireface800 has a switch on the back which has to be pressed manually).

I was reminded of the importance of this in an email from Dave Peck. Dave had asked Keith Johnson a question on my behalf and as part of his reply, Keith said, " I did observe that line termination must be present to prevent severe overshoot that could mis-clock systems."

And it's this 'line termination' that I'm refering to.

Apologies if I misunderstood your previous post... I really don't mean to 'teach a grandmother to suck eggs' (strange expression - hopefully it's used in the US too!).
