Thanks for the reply barney, but none of these actually tell me the difference between Manchester and Manchester 2!
Anybody else know?

Maybe talking about line encoding which requires 2 frequencies.

The link provided by Barny on Feb 5 appears to provide the answer in an article by Roger Forster. The first definition is that the clock and data signals are exclusive or'ed to provide the data+clock output, and in the second case are modulo-2 added. The difference being that in the first case the data changes on the positve edge of the clock and in the second on the negative edge.
