K-Pod data wiring

[Wes Stewart-2]

When my better half asked me for gift suggestions and I mentioned a K-Pod she
thought that was a great idea since I've aggravated an old rotator cuff injury
by constantly using my right hand tuning my K3 and running a mouse. I've since
trained my left hand to run the mouse and thought I could run the K-Pod the same.

The problem is the supplied data cable is too short and too stiff.  (IMHO there
are other deficiencies but those might be the subject of another message)  
Unfortunately, one is left to manufacture a cable, since there is an
admonishment in the manual to NOT have a connection to Pin 1 (they don't want to
rile up Jim Brown I guess).  The puzzling part is that they warn that if a
standard RJ12 cable is modified (not sure how one would do this) to break the
Pin 1 connection, the end with the disconnect should connect to the K3.  So I
question: 1) Why should it matter?  2) If Pin 1 is unused why is it connected to
something inside the K-Pod?

As far as I can tell Pin One is connected to the reset pin on the CPU (Micro-controller)
I would assume it's the same on the K-pod as well.

The connector on the K3 appears to be a Programming connector for the main Micro-controller

You should be able to take an off the shelf 6 pin cable and carefully cut through the outer cable covering over pin 1.
Then cut a small section out off the inner Pin 1 wire and put a wrap of black tape over the cable to protect it.


I would think as long as the cut is close to the radio end it would be functionally the same as cutting it right at the connector.

I would thing the two main concerns are not having them connected and getting stray RF into pin 1 (hence cutting close to the radio end)

You are correct.  The worry is that a wire dangling on that pin will upset the
controller if RF or other noise is induced.  My informant had the bright idea to
use the existing cable to get out of the radio and dangle it somewhere to the
rear and then use an RJ12 female-to-female connector and a longer standard RJ12
cable to the K-Pod.  Not elegant but effective.  Parts are on order.
