K2 encoder kit 4 pin connector

Hi all,
Just finished the front panel on my 2nd K2 last night and in the process of building the encoder daughter board, I noticed there was an unused 4pin connecter supplied in the kit. Long story short, I ended up ruining the connector, but I don't see that it's actually used for anything.

I don't recall anything like this needed on my first K2 either that wasn't already supplied in the other kits.

Is this needed elsewhere later on or what is this part for?

Tnx es 73,

LS,

Yes, that 4 pin connector is extra - use it for whatever purpose you want.

There is a situation with the new encoder in that its board can contact
the back of the control board. That is not completely clear in the manual.
The area of the Control Board that could possibly contact the encoder
board must have the pins flush cut and the back of the encoder board
must also be flush cut.
In addition, a bit more space can be obtained by mounting the standoffs
on the back of the Front Panel board so the lockwashers are between the
board and the standoff instead of under the screwhead.
Make certain the two rubber bumpers are in place on the top of the Front
Panel board so they will contact the 2D connectors.

Re: K2 encoder kit 4 pin connector

Hi Don,
Ok thanks for the info. Whew, that's good because I managed to ruin it anyway having made a mistake with it that I'm too ashamed to admit to on the reflector hi hi.

And thanks for the warning about flush-cutting the daughter board. In fact, I did find some discussion of this in the archives so I went over mine with my flush cutters last night and got all the nubs as close as possible to the board. The manual describes putting the lock washer under the standoff also - maybe this was a change in the new manual? In any case, I checked the clearance with a straightedge over the two standoffs this am too and it's veeeery close hi hi. So I'll be careful with this at assembly once I get to that point.

I don't remember this on my first K2 which is #6882 I think. Maybe it had a different encoder? I'm too lazy to take it apart to look hi hi.

On to the RF board now. I'd forgotten what fun this kit is to build!

Actually, I just checked mine after finishing the flush cutting and the boards are going to touch when they're screwed together.

In the archives it was suggested to use electrical tape, but I'm thinking a more durable solution might be a thin layer of resin on the daughterboard as a more permanently attached insulator. Any thoughts?

Fish paper! Any day's a good day when a solution involves fish paper.

Resin would be difficult to remove should the need arise.

How about a thin piece of cork, often used in crafts?

Ah yes, cork is a much better idea.... thanks a million!

Well I think Rick's idea of cork is the way to go, though maybe it wont be as glamorous as fish paper! hi hi. And it'll stay put sandwiched between the boards too, I imagine...

Onwards to the RF board portion starting tonight. This part I remember well on my first K2, the parts inventory alone takes most of the evening :).
