[Elecraft] Need help with 6 meter setup for KRC2 with K3

[Lewis Phelps]

I know this topic has been on the list before, but all the discussion I have found raises questions but doesn’t give answers. 

I recently acquired a used RKC2, which I’m trying to set up with my K3 (barefoot version; 12 watts and no KAT3)

My question concerns the mapping for 6 meters.

The K3 manual refers to the Menu setting for the KRC2 as follows:
===========

"Controls the KRC2 band decoder’s accessory output settings. Shows ACC OFF or ACC1-3 if a KRC2 is detected; - - if not.
To ensure compatibility with both old and new KRC2 firmware, two different 6 meter band decodes are provided. Tap to select BAND6=B6 (addr=10) or BAND6=B10 (addr=9). Refer to the KRC2 manual for further details. 

============
However, I am unable to find anything in the KRC2 manual that discusses the mapping for the 6 meter band.  Presuming for discussion that I have “newer” firmware installed,

1. do I want to select BAND6=B6, or BAND6=B10? 

2.  what control line in the KRC2 should I use to energize devices associated with my 6 meter setup (e.g. coaxial relays used to connect the main K3 antenna port to an external 6 meter amplifier, rather than to my HF antenna).

ALSO

I find reference in prior discussion to  a Mac version of the KRC2 utility, but I can’t find it anywhere online. Does it exist?  Where might I get a copy? 

For that matter, where can I get ANY version of the KRC2 Utility that’s used for band mapping of the device? The only thing I can find on the Elecraft site is a Download program, not the utility that allows you to modify band mapping.

In sum, is there actually a way for me to use the KCR2 with my K3 in such a way that I can control external devices used for 6 meters? The K3 and RCR2 manuals are beyond opaque in this respect — a disappointing variance from the usual clarity of documentation.
