Canon G9 and trigger issue

Hello experts :-)
Currently using a canon G9 for aerial but have some probs. I control the trigger and settings thru a remote system by usb interface (vp-systems camremote2). First of all the I just found that when controlling the camera thru the usb the RAW settings wont work . And some other settings like TV and Av goes half auto so my shuttertimes goes high and result is fuzzy pics. Its all mounted on a askman 50 with pan and tilt.

So for testing, I downloaded and installed CHDK for the G9 (http://chdk.wikia.com/wiki/Downloads)(latest version)
Managed to configure it all, the camera with the CHDK and the remote control. The camremote "talks" to the G9 but.. when I trigger the shutter from my TX, it "only" focuses but doesnt take the picture.. like if the impulse was wrong or to "short/small".. Is it possible to configure the pulse, and if so to what and where? The CHDK seems to "take" over the settings as I wanted, so thats fine! Manual picutres works perfect with the CHDK and all the settings I made.
Tried different values from the TX, from 90% to 135%, same.. VP-systems camremote2 has an usb/chdk configuration, could it be in that, meaning needs software change?

Or better ideas? Scripts?

Thanks for all help an ideas.

I am not very familiar with the basic CHDK but I think there is an option to enable a 'fast' trigger mode where the photo is taken as soon as a USB high voltage is detected.

Normally, first on/off pulse focuses and second triggers.

I do not think you need to.

We will soon find out.

Replace DISKBOOT.BIN with this version :-

http://www.zshare.net/download/63230034fe6ee80e/

In Bracketing/Overrides menu set focus-mode to 'manual'.

(it does not actually put your camera into manual focus mode, it is a little 'trick').

At top of screen it should say FAST.

That means a photo will be taken as soon as USB pulse detected.

Does it work ?

Thanks mate, but no.
The "fast" appears and the cam tries, but stops with the focus fix and then goes back.. if I keep holding the trigger, manuel on this HW (camremote2) or the TX, it does the same.
Im running the lastest chdk, maybe I should try elder ones?

Hold abit now!.. After couple of reboots, removing the card for RAW checks etc... it works.. lol..

Thanks very much!
Going to do some tests... I'll back here.

Is it OK to go with this chdk?

that really should work, I have just tried with my A620 and a simple USB remote switch.

People use that mode with Aurico and the gentLES receiver with the single pulse-width output.

Plug your camera into your PC, it should take a photo immediately.

EDIT:

OK, posted as you replied.

If you want to hide the header at the top of the screen, in menu Stereo \SDM Header choose none or compact.

You have a new option in the Advanced\OSD Parameters\Zoom value, you can display horizontal field-of-view in degrees.

As to whether it is OK to use that version, you tell me

Thanks alot mate.
Just took it for a ride and good damn it works!
Its a biiit slow with RAW of, but hey, this ait the fastest camera and I bet I could get a better SD card, wich will be done tomorrow! The most and best is:
TV, AV and RAW + trigger now works as it should, controlled by ME!
Found 1 more future, if I do a fast trigger on my radio the camera locks and wait until next trigger and it snapps faster then ever :-) Perfect for aerial with vibrations etc!

Thanks again.. so strange.. here I am in Sweden.. novice and kinda... lost.. and hour later, its all fixed, all beacuse of a friendly internet friend! :-).. the power of wiki, forums and search tools :-)... oh well computers aswell ;-)
