3.1.1 Shutter Operation

The TM-7200/TM-6200 has a substrate drain type shutter mechanism which provides a superb picture
at various speeds without smearing. Manual shutter speed control can be selected at 1/60, 1/125, 1/250,
1/500, 1/1000, 1/2000, 1/4000, or 1/10,000 sec. rate.

3.1.2 Asynchronous Reset with Shutter

The TM-7200/TM-6200's asynchronous reset is flexible and takes external HD for phase locking.
Applying a VINIT pulse resets the camera's scanning and purging of the CCD.
When async reset pulse (VINIT) is applied to High state (+5V) with dial
switch select from1 to 9, the TM-7200/TM-6200 asynchronous camera
discharges the photo charges into the substrate drain although the camera is
still running on its sync timing and only outputs captured video. When the
negative going reset pulse is applied, the camera will latch the falling edge
to its next horizontal drive and reset vertical sync timing immediately. Then
it starts integrating for the period of shutter control set by either an external
pulse width pulse or internal shutter control. Therefore the horizontal phase
will not be interrupted. The TM-7200/TM-6200 asynchronous camera will output one field of shuttered
video after reset.
