It is possible to make 23 timings with the dip switches ... so one for on/off
The timing off the bursts must be exact!
With my D80 the unit was placed at the back shell and the back off the IR receiver.
You have to try this out. Good luck!
Cheers! However, I'm not sure to understand regarding the timing of the bursts. Do you mean the IR protocol ?
Additionally, here's GentLED feedback:
This is tricky. You can remove the black plastic housing, that reduces the size to 38x24x13mm, but that excludes the toggle switch that sticks out. See the jpg I attach, you can see the shape is not square so that may help?
Note that the IR light comes out of the top side and this must point to the IR sensor on the camera. It needs to be within 5cm and doesnt need to be straight towards it. For a small charge we could make one without box and with IR LED on short wire so you can lead it nearer camera sensor? This is a little fragile but once installed in housing it may be good Does this help?
In the Aquatica housing, the largest space I can figure is underneath the camera on the left. But the toggle switch might stick out too much from the back of the camera against the housing's lip. Maybe a replacement with a push switch is enough.
With the IRled pointing from the left front underneath the camera, the 5D sensor might catch the signal.. Otherwise, I asked for a quote with a short wired IRled and if the wired IRled can be easily replaced.
Standard unit is currently 30 pounds so it's worth a try.
