5 Synchronizing Cameras
Note: Please refer to “Appendix D: Power and I/O Connections” on page 85
for electrical specifications. Do not experiment with these connections if you
are unsure of compatibility with your source as they are very sensitive to over
voltage and can be easily damaged.
5-1 Sync In
Per Frame:
The IL3 is easily synchronized to an external
device such as another camera, or a
precision timing generator. The “Per Frame”
option is used when you wish the camera
to capture at a rate of one sync-pulse per
frame or fewer.
To set up Sync-In:
1. Open the Record Controls tab in
Fas
M
otion.
2. Click on the “Enable Sync In” check box to enable Sync In.
Note: As soon as Sync In is enabled, the camera need a sync pulse in order to continue taking Live
frames. You may not notice this immediately because Fas
M otion will continue to display the last
frame it captured.
3. Select Rising Edge or falling edge depending on your preference.
4. Select Per Frame. (Per Second Synchronization will be covered in the next section.)
5. Set the master frame rate. This is the speed in Hertz of the input signal. It is important that the
input signal does not exceed this because this is the number the camera will use to calculate
integration timing.
6. Set the rate divisor. In the example shown in “Figure 5-1: Sync In Settings Dialog”, the desired
frame rate is 250, while the Master Frame rate is 500, so a divisor of 2 is used.
7. The camera’s frame rate will now be set at 250 and all of the shutter settings are adjusted
accordingly.
In this example, the Max (frame rate) is 506. The camera’s resolution was set at 1280 x 1024 for which
506 is the maximum frame rate. If you wish to change your maximum frame rate, you must change
the resolution in the Record/Settings menu.
