Trigger Signal Input
13
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.
* DC IN connector 4th pin and 7th pin are available only when the GPIO input/output setting is switched to input.
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.
Use the 11th pin to input a trigger signal
The DC IN connector 11th pin is 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 DC IN connector 11th pin is selected as a trigger input,
when the terminal is open, the trigger will be activated.
Use the 4th or 7th pin to input a trigger signal
When input is via the 11th pin, the high level value varies between 2 V to 24 V and 3.5 V to 5.5 V. Low level value is
0 V to 0.4 V.
Use the 10th (ISO+) or 8th (ISO-) pin to input a trigger signal
When input is via the 11th pin, the high level value varies between 2 V to 24 V and 5 V to 24 V. Low level value is 0 V
to 0.4 V.
