I have downloaded and installed a script from Gentles who supplied a RC remote USB trigger/remote zoom for my A495. The trigger works fine but not the remote zoom. Any ideas?

I presume you have a gentWIRE-USB2 and are trying to use the ZoomNShoot.bas script available at http://www.gentles.ltd.uk/gentwire/chdk_sdm/index.htm

What exactly happens when you try to control the zoom (e.g. what do you see on the camera's LCD)?

Hello, all that happens is the same as if I tried to trigger the shutter ie the shutter fires but NO zoom. I DO have the USB 2 from Gentles - correct.

Try this version of the script. I added one line to display the value of the USB pulse in your camera's display. Let me know what value is printed ?

Code: [Select]

@title gentled chdk2 A-series Zoom and Shoot - Version 2
rem author Dave Mitchell - dave@zenoshrdlu.com
rem this script lets a Gentled CHDK2 use two servo channels to control zooming and shooting
rem 
rem It's designed to work on A-series cameras which have a small number of zoom steps.
rem It will not work properly on S-series cameras, because these have 128 zoom steps.
rem 

while 1
   do
      a = get_usb_power
   until a>0
   print "pulse=",a
   if a < 5 then gosub "ch1up" 
   if a > 4 and a < 8 then gosub "ch1mid" 
   if a > 7 and a < 11 then gosub "ch1down" 
   if a > 10 and a < 14 then gosub "ch2up" 
   if a > 13 and a < 17 then gosub "ch2mid" 
   if a > 16 and a < 20 then gosub "ch2down" 
   if a > 19 then print "error"
wend
end

:ch1up
   print "shoot"
   shoot
   return

:ch1mid
   print "channel 1 middle"
   return

:ch1down
   print "channel 1 down"
   return

:ch2up
   click"zoom_in"
   print "zoom in"
   return

:ch2mid
   print "channel 2 middle"
   return

:ch2down
   print "zoom out"
   click "zoom_out"
   return

return
