JAI TM-1020 用户手册

The TM-1020 series can be reset with external reset pulse (VINIT). Set the dial switch to “9.” Apply a 
pulse-width control VINIT signal generated from an external event trigger to the camera. The internal 
reset pulse will be latched to HD and at the 9th HD timing from the external pulse leading edge 
(negative going edge). The CCD discharge pulse will be generated to clear the images. The internal 
VINIT will be generated at the following edge (positive going edge) of the external pulse, resetting the 
internal timing including the video sync. The shutter speed is the same as the external pulse width, but 
the integration delays 9H from the leading edge. For the immediate reset option, please contact JAI, Inc.

For the progressive format, one frame of video output will start from the rising edge of the pulse width 
control. When VINIT is kept high (5V), subsequent frames will contain black or invalid video until the 
next falling edge of Vinit triggers another frame.
