Hi,

Does anybody know what Manchester II coding is? I know what
Manchester and differential Manchester is, but I can not find anything
on Manchester II . Please enlighten me or point me to a reference
source, standard, etc.

TIA

Manchester II is similar to Manchester, except it includes a 3 bit
time sequence to classify what follows as Control or Data bits. The
sequence comprises 1.5 bit times high followed by 1.5 bit times low,
or vice-versa. (I forget which is the Control and which is the Data
classifier.) These are normally used to begin transmissions frames.
US military standard MIL-STD-1553 is a well-known protocol which uses
Manchester II coding. I believe is mostly used on board aircraft. It
uses frames comprising a control/data sequence (3 bit times) followed
by 16 control/data bits followed by a parity bit, for a total of 20
bit times per frame.

That's an answer? How can us poor English speaking slobs
benefit from this?

I can assure You that You benefit a lot by not understanding
foreign language *abuse* like the words above :-)

Don't know either of the gentlemen so I cannot tell if it is motivated or
not

Take a look at the Harris HD6409. Perhaps the documentation will
explain the differences.
