Fig. 59: Exposure Time Offsets Depending on Device Link Throughput (acA200-165u and acA2040-90u Cameras
Only; All 8 bit- and 12 bit-Pixel Formats)
To obtain the wanted exposure time with trigger width exposure mode:
1. Subtract the value for C
4
(see Table 32 and Figure 59) that applies to your camera model, from
the wanted exposure time.
2. Use the resulting time as the signal high time for the ExFSTrig signal if the signal is not
inverted or as the low time if the signal is inverted.
