Trigger Signal Input
Trigger signals can be input via the 4th, 7th, 10th, 11th pins of the DC IN connector, the CC1, CC2, CC3, CC4 pins of
the Digital IF connector, or the software command. Switchover of the trigger signal can be changed via the TRG-SRC
command.

TRG-SRC
Trigger signal polarity
Positive refers to a trigger signal polarity activated while rising from Low to Hi, or during the Hi interval. Negative refers
to a trigger signal polarity activated while falling from Hi to Low, or during the Low interval. The default value of a
camera is Negative. The GPI connectors 1, 2, and 3 are pulled up on the camera side. When a connector is open, the
trigger signal is at the high level and is logically inactive. Note that when Positive of GPI1, 2 or 3 is selected as a trigger
input, when the terminal is open, the trigger will be activated.
