External Trigger 
The External Trigger lets you 
set up a sensor to trigger an 
action. This is used in any 
situation where you wish to 
autonomously trigger the 
flash, start the 
intervalometer, or take an 
exposure caused by some 
sensed event. 
The sensor will be detected 
when you plug it into the 
External Trigger Port (ECP) 
on the Master. 
Sensor modules such as an Audio Detector, Optical 
Detector, or Digital Trigger are available on a per 
request basis subject to availability. You can also 
plug in a switch to the Trigger Port to trigger from 
switch closures or provide your own sensors. A 
detailed specification for trigger port sensors is 
available upon request.
