In preferences only Camera section is of main interest.
• Video- Format and Video-Mode are related to the DCAM specification settings. (See 4.5
for tables)
• X-Offset and Y-Offset are available if the camera supports partial scan and describe the
upper left start-corner of the image
• X-Size and Y-Size adjust the size of the partial image.
NOTE: The camera itself may change these values to the ones it supports.
• Framerate sets the desired rate in frames/s according to the properties of the camera.
• Packetpayload is calculated according to the settings above per IEEE1394 ISO cycle.
• Colormode enables various settings according to the abilities of the camera.
• Triggermode (int.) is the continuous mode whereas (ext) is the trigger mode. This mode
needs a negative edge of TTL level at the Trigger input connector of the camera. You get
triggered images with a maximum frequency according to the framerate setting. This is
important to know because it allows to adjust bus bandwidth! But: The camera will drop
images if the trigger frequency is higher than the Framerate setting!!
• TX- Speed refers to the max bus frequency and should stay at 400. Only users of the
DFW-X300 must switch down for this camera to 200 Mb/s. Other cameras connected to
the card may operate at 400 Mb/s.
