ZED Link Mono GPIO Triggering

The ZED Link Mono GMSL2 capture card allows to synchronize external sensors by using triggering signals on the 6 pins 2mm pitch GPIO connector J4.

Master mode - Trigger out #

The ZED Link Mono capture card is configured to operate in master mode by default.

It is not required to enable the output synchronization signal which is available on the pin #6 of the GPIO connector J4 as soon as the Jetson device boots and the ZED Link GMSL2 driver is installed. The default output signal is 60 Hz if no camera is opened and configured with a different frame rate.

  • Connect the ground signal (Yellow - GND) to the pin #1.
  • Connect the trigger out signal (Green - MFP0) to the pin #6.

Triggering signal #

The output trigger signal is a square wave, with its rising edge synchronized with the end of the exposure phase of the CMOS sensor.

The signal has a fixed Amplitude of 3.75V +/- 12%, while Width and Frequency change according to the frame rate setting of the camera.
