Sequential Trigger Mode (Eps Trigger) - JAI CM-030GE-RH User Manual

8.5.5 Sequential Trigger Mode (EPS trigger)

This mode allows the user to define a preset sequence of up to 10 images, each with its own
ROI, Shutter and Gain values. As each trigger input is received, the image data with the
preset sequence is output as described below.

operation
Signals added to trigger can be selected by 0xB060 Camera Trigger Selector in the register
map via GPIO. The camera will functions on the rising edge of the trigger and Negative or
Positive should be determined accordingly.
The following default settings can be modified by the user to define a sequence.
ID
Width Height
1 656
2 656
3 656
4 656
5 656
6 656
7 656
8 656
9 656
10 656
The following registers are used to configure the sequence.
0xC0F4 Sequence Repetitions (Number of Repetitions – Note: 0 = repeat indefinitely)
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 to (1) for start
0xA040 Set Normal Mode to (0) for stop
Note:1) As for the details of register, refer to
Note:2) It is recommended to set the exposure time in the order from the shortest to the longest one.
Note:3) The minimum trigger interval is > Exposure time (expressed in L(Line)) + FVAL on Normal scan ( 511L) +
1L )
Note:4) Do not input the trigger just after the sequence is reset. It requires at least 500ms delay.
Note:5) In sequential mode, the exposure should be adjusted so that the LVAL async mode can always
function.
