tim er for fram e rate and a p rogram m able exp osu re p e riod .

External trigger: Exp osu res are controlled by an external trigger signal. The external trigger
signal can be either a Cam era Link control line (i.e. CC [4 : 1]) or a general p u rp ose inp u t (e.g.
GPIO [2 : 1]. General p u rp ose inp u ts are isolated by an op to-cou p ler inp u t w ith a tim e
p rogram m able d ebou nce circu it.
