6.6 External Synchronization and Gen-lock
(via Camera Link interface ONLY)
The UP-1800 camera automatically locks to the external sync source. The external sync source
must match the camera HD and VD specification, which are 31.367 KHz and 30.0 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 UP-1800DS-CL 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.
