Basically, the SYNC provides a signal to synchronize the
video with other video equipment. Sometimes the video
equipment that is used with PULNiX cameras require the
necessary SYNC signals to drive a camera. In this situa-
tion, the camera must have the ability to accept an exter-
nal sync source. Note: Not all of PULNiX cameras
accept an external sync source. So make sure to read
the data sheet and look for sync specifications to deter-
mine if the camera has that capability.
Interlace and Non-Interlace Video
Interlace and non-interlace video is the way the actual
horizontal lines of video information will be scanned out,
for example, to a video monitor. The standard operation
is the interlace mode. In the interlace mode, the first field
is scanned out on the monitor which is the odd field (odd
horizontal video lines). Once the odd field is completed
the even field (even horizontal video lines) is started back
at the top (known as retrace) and scanned down until it
reaches the bottom. Remember, each field is timed 16.7
msec. apart. The interlacing mode of operation is the
most common way of displaying video on a monitor.
For non-interlace mode, the camera will only scan out the
same field over and over again. On most of PULNiX's
cameras, this will require the camera to be operated with
an external sync input only.
Camera Features
At this point we will get into more of the specific functions
that are applicable to PULNiX's video line.
Lens Mount
Again the best place to start is at the front end. The front
of the camera is where the lens will be attached. The two
most common type of mounts are the bayonet and the C-
mount. A majority of the cameras come with a C-mount
type thread on the front end. Some of the older models
like the TM-34K and TM-540 have bayonet mounts. The
newer models can use bayonet type lenses with a special
adapter part# BC-5 (note this adapter functions as a
close-up ring). Also the bayonet models can be easily
adapted to use C-mount type lenses as well. For your
information, lenses will be discussed further down the
road.
Tripod Adapter
PULNiX's full line of video cameras have the feature of a
tripod mount adapter. This will allow a user to physically
mount the camera to a fixture such as a camera tripod
stand. The video standard is a 1/4" coarse thread for the
U.S. market. Some cameras also have a M6 metric
thread available. To determine what type of thread
dimensions are available for a particular camera look at
the camera data sheet under dimensions.
Camera Back End
The back end of the camera is where most of the action
takes place. This is where the camera's power, video,
sync, auto iris controls, and shutter control are located.
The majority of our camera line has the following configu-
ration in terms of the type of connector.
