			Hmm... 6311... I'm going to assume that's the non-RFX f/x card (as I don't actually have documentation for that one in my library).  The RFX32 card was upgrade 6864, I think.
This (6311) is the add-on F/X card for the e6400-Classic.  Unlike the E4XT, the e6400 didn't come with F/X as standard, hence the add on board.  It's standard on the Ultra models.
There are no issues that I know of with this card... unlike the RFX32 card, which works fine in EOS 4.62, but has serious issues with EOS 4.7
I like it.  Sure, you'll get a lot farther with an outboard, dedicated effects unit, but it's quite usefull for adding a little colour to your sounds.
