Cautions in the Pulse Width Control Mode.
1.Pulse width control mode is effective only in
2.The exposure start may be delayed up to 1H max., when the falling edge of ext. trigger pulse is not synchronized with the falling edge of ext. HD signal. To avoid this 1H jitter and delay, the falling edge of the ext. trigger pulse should be synchronized within 4.4 usec. to the HD pulse. It can be the ext. HD in or the Internal HD out.
See cautions in Edge
3.The voltage level of the ext. trigger has to be 4.0
