TECHNICAL REFERENCE
Cameras of the 7700-2 series provide
10-bit output in Camera Link format to an
external frame grabber.
Operating in progressive scan mode,
they use a 1/2-inch sensor to provide 1004
× 1004 pixel resolution at 30 frames per
second.
Higher frame rates can be established,
but with a corresponding reduction in the
number of lines available for readout.
The color version (7720-2) of this cam-
era has an antialiasing lter in front of the
sensor. Sensor color ltering is the Bayer
pattern. All color processing is performed
by the external computer.
Operation in the UV region, (250-400nm)
requires a model 7732-2000 version of the
camera — which has the sensor faceplate
glass removed.
Setup and control of the camera is through
the rear-panel MDR connector operating via
asynchronous serial communications.
Offset, gain, and other functions are ad-
justable through this serial interface. Preset
camera congurations can be established to
allow for a rapid change of duty.
Inserting a paper clip through a hole in the
rear panel performs a hard reset. Also on the
rear panel is a green indicator that illuminates
when the 12 V dc power is applied.

LINK
Camera link 26 pin connectors require special tooling to assemble.
Thus, cables are only available pre assembled.
Note: All cameras can use cables of the 3M company 14B26 series (table 5).
However, for cameras above serial number 410368 only cables of the 14T26
series can be used (table 6).
