6.6 External Synchronization and Gen-lock
(via Camera Link interface ONLY)
The UC-610/UC-610CL camera automatically locks to the external sync source. The external sync
source must match the camera HD and VD specification, which are 55.554 KHz and 110.0 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 Integration
(via 12-pin Hirose connector ONLY)
The UC-610/UC-610CL 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.
