PRELIMINARY

3.3.3 ExSync, Programmable Mode

When using the ExSync programmable mode to control exposure, several guidelines must be

followed:

• ExSync must remain high for a minimum of 1 µs.

• ExSync must remain low for a minimum of 1 µs.

• Timer 1 must be set to a minimum of 10 µs.

• Using full resolution, the minimum ExSync signal period is 2 ms for the A504

k/kc, 2.485 ms

for the A503

k and 13.52 ms for the A501k/kc.

• If the AOI feature is used, the minimum ExSync signal period is equal to

1/Maximum Frame Rate where the maximum frame rate is determined by the suitable for-

mula in section 3.11.1.

Assuming that these general guidelines are followed, the reaction of the camera to a falling

ExSync signal will be one of four cases, which are described in sections 3.3.3.1, 3.3.3.2, 3.3.3.3

and 3.3.3.4.

The FlashOut signal can be set into a mode where it is high while the effective ex-

posure occurs, i.e. while the Integrate Enabled signal is high.
