External Triggering with the ST4

For all released versions, "R" versions of the firmware, external triggering is in there.  Unlike the TB3, where we actually selected "Ext. Triggering" from our interval during setup, ANY timelapse can be triggered externally when the program is paused.

Externally Triggering from the I/O port

1. Insert the i/o triggering cable to the side of the spectrum.  This is the stereo port on the right under the i/o icon.  Watch out, don't put this in the camera triggering port or it won't work.
2. The other end of the trigger cable can be a manual external intervolometer, or a bramper solution like The View.  If you are using the view, use their AUX2 port.
3. On your ST4, set up a timelapse shot and start it.
4. Pause the program by hitting the X button or the center of the onboard joystick.  If you need to jog back to the start, use the left DPAD or joystick to scrub to the beginning of your shot.
5. The I/O port is now "looking for a signal telling the spectrum the camera’s shot is complete to allow it to move the next position.  Once received, the spectrum will advance to its next position.

Manually triggering a shot for stop motion from the PS4 Dualshock

1. On your ST4, set up a timelapse shot and start it.
2. Pause the program by hitting the X button or the center of the onboard joystick.  If you need to jog back to the start, use the left DPAD or joystick to scrub to the beginning of your shot.
3. By hitting the R1 button on the PS4 remote, the spectrum will send a shutter signal to your camera through the camera triggering port, and then advance to the next position and wait.
4. Move Wallace or Grommit, or whatever other stop motion subject your are shooting.
5. When ready, hit the R1 button again.
6. Repeat.
7. If you ever need to reshoot or go back, you can scrub anywhere in your move by using the Dpad left and right buttons.

 Reasons to externally trigger:

• Want to manually advance a shot (stop-motion).
• Want to use a ramping solution and need to time motion.
• Want to synchronize multiple motion control rigs.

Special Notes for Beta Software

• The i/o port is a triggering port AND a communications port for serial communication.   Starting in our Beta R007_9, we allow users to configure the port to use three ways, Ext. Trigger, eMotimo API, or Dragonframe.   Make sure have selected Ext. Trigger for the above modes.
