Sequential Trigger Mode (Pre-Select trigger)

The ROI, Shutter and Gain values can be preset up to 10 sequences. Along with every trigger input,
the image data with the preset sequence is output as described below.
Trigger
Sequence
Operation
Signals added to trigger can be selected by 0xB060 Camera Trigger Selector on register map via
GPIO. The camera will functions on the rising edge of the trigger and Negative or Positive should
be determined accordingly.
For the sequence, the following default settings are installed.
ID
Width
1 1392
2 1392
3 1392
4 1392
5 1392
6 1392
7 1392
8 1392

The following registers are used to configure the sequence.
0xC0F4 Sequence Repetitions (Number of Repetitions)
0xC0F8 Sequence Ending Position (Ending Position)
0xA30C Sequence Reset Command (1 only)
0xB060 Selection for Camera Trigger 0
0xA040 Trigger mode selection and 0x09 for Sequential EPS mode
Example of settings
Setting: Repeat 5 times from ID 1 through ID 8
0xC0F4 Set to 0x05
0xC0F8 Set to 0x08
0xB060 For instance, Pin 6 of the 12-pin Hirose connector for Opto IN 1
0xA040 Sequential PS (9)
0xA3F0 Set this for start
0xA040 Set Normal Mode (0) for stop
Please refer the detailed register description on Camera Register Map which is included in the SDK.
The following table shows the minimum trigger interval in a-synchronous accumulation mode. In
the sequential mode, only a-synchronous mode is functional. Therefore, the trigger timing should
be set so that the timing is not in synchronous mode.
