This is a 3 metre cable terminated with a 4 pin hirose conector at one end and a BNC plug at the other.

In addition to a number of other applications, The Imaging Source USB, FireWire and GigE CCD cameras are also
used for industrial purposes. Most of these applications require a trigger input and general purpose digital I/Os.
These features are provided by all USB cameras whose product code contains a "BU" (e.g. DMK 21BU04, DFK
41BU02.H, etc.), all FireWire cameras whose product code contains a "BF" (e.g. DMK 31BF03-Z, DBK 41BF02, etc.)
and all GigE cameras whose product code contains a "BG" (e.g. DMK 21BG04, DBK 41BG02.H, etc.).
The trigger input of all these cameras is available via a BNC connector and thus very easy to access. The access of
the digital I/Os depends very much on the application. Therefore, basically all USB and FireWire cameras offer a pin
header that can be accessed through a hole in the cameras backplane. Please note: GigE cameras do not provide
this pin header.

For all users who prefer to access the digital I/Os using an external connector, The Imaging Source offers cameras
with a 12-pin Hirose connector on the camera's backplane. The product code of these cameras ends with the
suffix ".H" (e.g. DMK 21BU04.H, DFK 41BF02.H, DBK 31BG03.H, etc.).
