This camera can operate in 5 primary modes. 1 non-triggered, 3 external H synchronous trigger
modes and 1 long time integration mode.
1. Normal continuous Mode. Pre-selected exposure.
2. Edge Pre-select Mode. Pre-selected exposure.
3. Pulse Width Control Mode. Pulse width controlled exposure.
4. Start Stop Mode Exposure start on trigger, end after ext. VD
5. Long time integration Accumulation controlled by ext. VD interval
In normal continuous mode and edge pre-select mode the shutter time can be selected from the
8 fixed steps. To avoid jitter, the trigger should be synchronized to HD as shown in fig. 11.
