6.6 External Synchronization and Gen-lock
The USS-600CL camera automatically locks to the external sync source. The external sync source
must match the camera HD and VD specification, which are 31.49KHz and 59.97Hz respectively.
Both external HD and VD are TTL level signals.

Pulse width: 5-50% duty cycle, see figure 8 shown below.

6.7 Integration
The USS-600CL camera can be integrated up to 2 seconds without severe noise or dark current
effect. To start integration, pin #11 (same as pin #27 of 40-pin digital connector) of the 12-pin
connector must be connected to GND or 0V. The integrated video will be shifted out following the
next vertical drive after pin #11 goes back to high or 5V level, as shown in figure 9 below. If a
frame grabber does not capture the immediate frame or integrated video, the normal video (before
the integration) will display again on the monitor.
2.5V to 5V
0V or GND
2.5V to 5V
0V or GND
