6.6 External Synchronization and Gen-lock
(via Camera Link interface ONLY)
The UC-900CL camera automatically locks to the external sync source. The external sync source
must match the camera HD and VD specification, which are 15.73KHz and 14.98Hz 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-900CL 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.
