Detailed switch and jumper setting is described in “7. Mode Setting”.
For connections see “5. Pin Assignment”.
Cautions in the Edge
1.Edge
2.The exposure start may delay 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 delay and jitter, the falling edge of the trigger pulse should be synchronized with the HD pulse as shown below. It can be the ext. HD input or the Internal HD output.
3.The ext. trigger input is 75 Ohm terminated as factory setting. (R127 short and
voltage level of the ext. trigger has to be 4.0
4.If the ext. trigger input and ext. HD input are from a source with TTL level, set
