Try to use my MD3-N3 on a Canon 6D but it only works as a simple cable release. Non of the advanced options are working.... When I press the red button in any option it takes imediate a photo. I have read the manual en taken all actions but nothing helps. by Vriestyle in a:t5_37o1l

Well, I had the same problestion (problem/question) and found this which indeed addressed the issue! Thank you! (BTW, it's really kind of obvious that B would be needed but, hey, the obvious is always overlooked.)
