Mapir Survey 3/2 HDMI PWM Trigger Cables
Use this cable to send a PWM (pulse width modulation) signal to Mapir Survey3 or Survey2 cameras to perform various functions. The diagram below shows the HDMI pins that are connected and the required PWM pulse to send depending on the function you want to perform.
In order to trigger the shutter (take a photo) on both cameras you should send a 2000us pulse. Use the 1000us as a neutral, do not do anything level.
For Survey3 cameras, you can also send the camera a 1500us pulse width to have the camera enter USB Media Transfer mode. If the camera is connected to a computer using the USB/POWER/FPV port, when in transfer mode the camera's SD memory card will then become mounted to the computer and you can access it as if the SD card was plugged into the memory card reader on your computer. This is very useful if using a companion computer on a drone as it is possible to extract the images from the camera and onto the computer's memory. Then you can do anything you want, such as process the photos or store them onto an external memory stick or SSD to easily take the photos off your drone.
