Basic Operation and Features

3-24 Basler A500k

PRELIMINARY

3.3.4 Free-run Mode

When using the free-run, programmable mode to control exposure, several guidelines must be

followed:

• The internal control signal must remain high for a minimum of 3 µs.

• The internal control signal must remain low for a minimum of 10 µs.

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

2.485 ms for the A503

k, and 13.52 ms for the A501k.

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

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

formula in section 3.10.1.

Assuming that these general guidelines are followed, the reaction of the camera will be one of four

cases, which are described in sections 3.3.4.1, 3.3.4.2, 3.3.4.3 and 3.3.4.4.

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

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