Ricoh GR IV camera triggering, duty cycle and period

1

Hi everyone,

We would like to trig a Ricoh GR DIGITAL IV with a reach rtk unit. We made custom cable following the available information on emlid website

We are getting the hotshoe returns but can not trig the camera with our reach.

How can we find the duty cycle information for a specific camera (Ricoh GR IV and other)? Did someone already experience issue with ricoh GR IV ?

One more question, how can we compute duty cycle from PWM values? I am a bit confused with the duty cycle as mentionned in the reach view. As far as I know, duty cycle is expressed in % and not in ms as in reachview.

Regards

Adrien
