BG2 Battery Grip Pin Layout

I did a search for the the layout of the pins on the battery grip for the K10d/K20d, but couldn't find anything.
Does anyone know where I could find it or if they have some information that could help?

Here's the problem: Too many times I have the camera set up in Av or TAv and I accidentally hit the Green button on the grip. This changes the settings I had originally set. I usually don't notice until I've taken quite a bit of photos.

My solution: I'd like to try and cover the corresponding pin(s) with some sort of insulation to prevent the Green button from working on the grip.

Can anyone help?

-If not shooting in portrait, turn the grip off. I had a problem with firing the shutter when carrying my K10 over my shoulder.
-As far as the green button in general...I'm not sure if the pins are individual circuits or a data connection.

Each pin isn't carrying a different signal (like an old analogue hifi connector). They all carry data - so the pins are working together more like a usb connector.
If you cover one pin, it will stop the connector working altogether.

In TAV or M, you can set your camera to have the green button disabled. May or may not help here.

Thanks for the replies.

I tend to switch between landscape and portrait a lot sometimes when I'm shooting, so this wouldn't work for me too well.

On my camera (K10d) you can only choose between Program Line, Tv Shift and Av Shift for the Green button function. There is no option to disable it.

I'm looking to get a K5 in the near future, and a grip to go with it eventually. It looks like the layout of the green button on the grip will help reduce the chance of accidentally hitting it.

Again....Thanks for your help!

The pinouts are mentioned in this thread.

Well if you do bump up to a K5, I just checked and you can disable the green button, but the button on the bg4 is easily pressed, as it is right where your thumb rests.

Thanks for the link to the thread. Unfortunately the links in that thread don't work anymore, but it lists the pins and their corresponding functions.
I took a small piece of tape and covered pin 10 (Green Button). I put the grip on the camera, turned it on and the green button was disabled!
Everything else seemed to work properly.

I'm thinking of using a really thin plastic tube with the end melted shut to place over the pin as a more"permanent" solution. This way it's still completely reversible.

Thanks again for your help!

Can you post a picture of which pin is #10? This sounds like a great fix, and something I might want to do when I get my grip.

Thanks

The simplest solution would be to mask the green button on the grip with tape and a brass or plastic coated tack pin with the pin broken off. Even a thin ordinary shirt/pant button should work well. Place it over the green button and then put cello tape over it.
This is better then attempting to tamper with the pins on the grip or the camera. A simple reversible process too.
But what intrigues me is that I always have the grip on my camera and have never had problems with the green button - accidental presses or whatever??

Another solution: position a small rubber o-ring so as to protect the button from all but intentional activation. Contact/rubber cement or a dab of silicon sealer works OK and can be removed later if necessary. Available in the plumbing parts dept among other places.

I don't have a picture of the pins, but it's easy to figure out:

With the tripod mounting screw to the left of the pins it should look something like this:

1,2,3,4,5,6
7,8,9,10,11
12,13,14,15,16,17

The bold numbers are the pins from the battery and are a little thicker than the rest.

Hope this helps!
