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.

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.

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 µ 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.
