s Timing chart
To acquire images through an image grabber board, write parameters in the software program or parameter file by referring to
the following timing chart and description.

s External trigger mode
To acquire images in external trigger mode, input an external trigger pulse as shown below. When the time Tvd has passed after
the rising edge of the external trigger pulse, synchronous signals and video signals are output.

Tvd
Vsync+
(RS-422)
Hsync+, Pclk+ and Data 1-12 are the same as internal trigger mode.
· Tmin is defined as 1/Sf (int).
· Tmax is defined as the reciprocal of the minimum value of Sf (ext).
· Tvd=390 µs (C7942CA-02)
210 µs (C7943CA-02)
