Don't know if it is grammatically correct or not - 22 years since I did GCSE French - but perhaps some kind soul can advise the sw level required in the BS9000 for two to work as Master and Slave in the same ML grouping.  I am pretty sure BS9000 needed to be at least MK2 before it would function in A.OPT 6 but any advice (or correction of my French above) gratefully received.

Thanks in advance.
