5.11 External Synchronization and Gen-lock
The UP-600 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.
a) HD
H:
2.5V to 5V
L:
0V or GND
Pulse width:
5-50% duty cycle, see figure 8 shown below.

5.12 Integration
The UP-600 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.
