Pin 1, ENL
ENL refers to “Enable Line.” It is an active-high TTL signal and is asserted during the
valid pixel period on each line, as shown in the diagrams in Appendix A. It returns low
during the inter-line period between each line and during the inter-frame period between
each frame.
Pin 2, DIFF_RESET_OUT
This pin is an active-low TTL signal that is the buffered version of the CameraLink CC1
signal. The CC1 signal, driven from the host, is one of the software-controlled trigger
signals for the camera as described in Appendix A. The CC1 signal is brought out of the
