C8940 series
PCI board for CCD multichannel detector head
C8940 series is an interface board equipped with a PCI bus controller. Two types C8940 series are available: C8940 compatible with RS-
422 digital interface cameras and C8940-01 compatible with LVDS digital interface cameras. Both types can be directly connected to a
Hamamatsu multichannel detector head to perform image acquisition.
The internal dual buffer memory control circuit permits transfer of acquired image data to the PCI bus while acquiring image data. This
control circuit also allows monitoring and acquiring images without caring about the image data size.
C8940 series also has a trigger function that acquires images from a CCD multichannel detector head in free-running operation. It is
therefore possible to start acquiring a specified number of frames by input of an external trigger signal, or to acquire one image at each
input edge of external trigger signals, or to acquire sequential frames in a period specified between external trigger levels. C8940 series
can also generate trigger signals.
Furthermore, C8940 series has a frame rate measurement function to use during image acquisition, as well as a serial interface function
and digital I/O function allowing you to control the CCD multichannel detector head through a single camera interface cable.

s Selection guide
C8940 series is available with two different digital interfaces.
C8940 series has a 16-bit PCI panel connector, but also works with a 32-bit camera interface when an optional extended panel
(A9414) is added.
