Recommendations When Using Exsync - Basler L100k User Manual

3.2.1.2 Recommendations When Using ExSync

When using an ExSync signal to control operation, several general guidelines must be followed:
• ExSync must toggle.
• The ExSync signal period must not be lower than a defined minimum. The minimum ExSync
period for each camera version is shown in Table 3-1.

2048 Pixel CCD
Table 3-1: Minimum ExSync Signal Period
• The ExSync signal must remain high for at least 0.2 µs.
• The minimum exposure time is 1 µs. That means that:
In ExSync level-controlled mode, the ExSync signal must remain low for at least 1 µs.
In ExSync programmabe mode, the programmed exposure time must be at least 1 µs.
• In the ExSync Programmable mode:
Maximum allowed programmed exposure time = ExSync signal period - 1 µs.
• In ExSync edge-controlled and ExSync level-controlled modes, the relationship between the
the fall of the line valid signal and the rise of the ExSync signal must meet the minimum
requirements shown in Figures 2-4, 2-5, 2-7, and 2-9.
• When an exposure is triggered by the ExSync signal, the actual start of exposure can be
delayed by up to 1.3 µs. (This is commonly referred to as an exposure start delay.) The max-
imum delay depends on the camera model and the exposure mode that you are using. Table
3-2 shows the maximum delay for each camera model and exposure mode.
The actual length of the exposure time will be equal to the exposure time triggered by the
ExSync signal minus the delay. Actual exposure can be monitored using the Integrate Enabled
signal (see Section 3.4).
