Delayed Readout Eps And Pwc Modes (Eps And Pwc) - JAI AT-200GE User Manual

Important Notes:
 Minimum trigger interval is; Exposure time + 1252L(FVAL on normal scan) + 1L
 In order to operate this mode, it is recommended to set the shutter speed first at a smaller
value and then a bigger value.
 Do not input the trigger signal right after the sequence is reset. At least, 500ms duration is
needed. This may cause malfunction.
 ROI can be set for horizontal direction by 8 pixels increment. For vertical direction, it is 1
pixel increment.

9.7.6 Delayed Readout EPS and PWC Modes (EPS and PWC)

This mode can be used to delay the transmission of a captured image. When several cameras
are triggered simultaneously and connected to the same GigE interface, it allows the cameras
to be read out in sequence, preventing congestion.
The image data is not transmitted directly by the trigger 0 and is stored in the memory
located at the Ethernet Interface. By the falling edge of the soft trigger 1, the image data is
output.
The AT-200GE has up to 4 frames to store, and the stored image data can be output at the
consecutive timing of trigger 1.
This mode can work in EPS mode and PWC mode.
