6.6 External Synchronization and Gen-lock
(via Camera Link interface ONLY)
The UC-1830CL camera automatically locks to the external sync source. The external sync source
must match the camera HD and VD specification, which are
31.408 KHz and 29.998 Hz
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.
b) VD
H:
2.5V to 5V
L:
0V or GND
Pulse width: 0.5-50% duty cycles

6.7 Long Term Integration
(via 12-pin Hirose connector ONLY)
The UC-1830CL camera can be integrated up to 2 seconds. To start integration, pin #11 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. If integration is preferred to control via Camera
Link interface, consult UNIQ for further details.
