CC640 Digital Camera
6. Operational Description
6.1 Self Timed Mode
In self-timed mode the camera is capable of waking itself up and acquiring an
image. In order to place the camera in self-timed mode use the Device
Configuration Software to set the Self-Timed Interval parameter to non-zero.
Self-Timed Example 1:
To take a picture every 15 minutes starting at Midnight the self-timed mode
parameters should be set as follows:
Start Minute:
0
Stop Minute: 1440
Self-Timed Interval: 15
Self-Timed Example 2:
To take a picture every Hour starting at 4:00AM and ending at 11:00PM the self-
timed mode parameters should be set as follows:
Start Minute:
240 (4 hours * 60 Minutes)
Stop Minute: 1380 (23 Hours * 60 Minutes)
Self-Timed Interval: 60
6.2 External Trigger Mode
An image acquisition can also be triggered from the Ext. Input Signal on the
camera. It is recommended that a short pulse be used to initiate the image
acquisition. If a positive voltage is applied and not removed before the image
acquisition sequence is complete, the camera will begin another image acquisition
immediately after. An image acquisition can be as short as 10 Seconds.
NOTE External Trigger Mode can be used in conjunction with the Self-
Timed Mode by following all the steps as listed in this section.
