RJ-45 "Mystery" Connector (FP ACC)

[David Inger]

Page 13 of the K3 Owner's Manual states that the FP ACC is " (RJ-45, 6 pins) located on the bottom on the bottom of the transceiver, near the VFO B knob.  It is used with accessory devices."  

I may have missed earlier discussions, but has there been any additional clarification on the current or future use of this connector?  Is there any information on the "pin out" of the 6 pins on the RJ-45?

As has been stated before, it is used by Elecraft for test purposes. There was once a suggestion that an external keyboard might be able to plug in there. But if that does ever happen, it probably isn't going to happen for a very long time, and I can't see what it would offer that an Asus Eee PC (or similar) couldn't do a lot better with a similar footprint and cost.

Errr... allow you to use the radio WITHOUT ANY computer?

I would guess that any external plug-in keyboard gadget would be a computer of some sort, containing a PIC chip programmed with firmware. Considering the functionality such a device would provide, I can't see much reason for not choosing the already available alternative.
