Frame Rate Settings for Format 7

For Format 7, the offset address 600h frame rate settings are disabled, but with this camera, the frame rates for Modes 1 to 4 are determined by the packet size.

Functions

1394 Bus Synchronization

Timing used to start exposure is synchronized with the 1394 bus time cycle register.

If cameras are connected in a bus connection, they are automatically synchronized in a 1394 bus operation. As 400 Mbps frequency area restriction can affect the synchronization, you must set the video mode in which the cameras can transmit video signal at the same time. 1394 synchronization does not work in long exposure mode. In a long exposure, the exposure time is set longer than the image transmission cycle.

CPU operation timing can cause jitter in 1394 bus synchronization. (Approx. 4 ∝sec)

Hardware external synchronization will ensure further accuracy.

ExposureOut

When trigger is OFF, or software trigger is ON, a signal that indicates the exposure time is output from the BNC connector of the camera.

16-bit Mode

The camera supports 16-bit Black & white (Monochrome) mode, but because the output of the AD converter is 10-bit, only the least significant 10 bits of the 16 bits will handle data. The upper 6 bits will be filled with zeros.

exposure time

The LOW period that is given by an output wave form is an approximate guideline. It does not correspond exactly to the actual exposure time.
