Trigger signals are independent timing and control signals that can be sent between hardware along trigger cables. The trigger interface shows which of the trigger cable standards the camera uses.
Figure 1: SMA interface in the Dhyana 95V2 sCMOS camera
SMA (short for SubMiniature version A) is a standard triggering interface based on a low-profile coaxial cable, very commonly used in imaging hardware.
Figure 2: Hirose interface in the FL 20BW CMOS camera
Hirose is a multi-pin interface, providing multiple input or output signals via one single connection to the camera.
Figure 3: CC1 interface in the Dhyana 4040 sCMOS camera
CC1 is a specialized hardware triggering interface located on the PCI-E CameraLink card used by some cameras with CameraLink data interfaces.
