ExSync Line Synchronization with Electronic Shutter Control is the fourth mode (Figure 3.4.5). It gives the user asynchronous hardware control both start and end of integration. The control lines ExSync and ElectronicShutter are CameraLink TM lines CC1 and CC2 respectively as described in Reference A, and must be asserted by the frame grabber.

4.5 Lenses Fairchild Imaging does not supply lenses. 4.6 Positioning Accuracy of th e Sensor Chip in the Camera Positioning accuracy of the sensor chip in the horizonta l and vertical direction is + 0.2 mm. Rotational positioning accuracy is as shown.
4.9 Lens Modeling Several camera companies have included this and lik e information in their manuals. For reference material it is very useful. The focal point is the point at which the image of an infinitely distant object is brought to focus.
SECTION 5 Handling Instructions 5.1 Electrostatic Discharge The Fairchild Imaging LNL2048S is a metal oxide semiconductor (MOS) device, and as all such devices, has some limited inherent susceptibility to ele ctrostatic discharge (ESD). All reasonable and customary design steps have been taken to provide ESD protection circuitry.
SECTION 6 Troubleshooting 6.1 Check the Obvious Things Out First When trouble shooting, you want to start the process with the obvious components contained within your system: • Computer system: har.
Everything Seems To Be Working, But No Image Remove the cover from your PC and reset all the cards into the Mother board. Sometimes when you move your PC, cards inside the PC work themselves loose. Data Clocking/Output Signals Verify the presence of all data clocking and output signals.
SECTION 7 Product Support If after troubleshooting your camera, and you still have problems, collect the following data about your application and situation and call Fairch ild Imaging Customer Support.
REFERENCE A Camera Link TM Introduction Camera Link is a Protocol that is Implemented in Channel Link Hardware Camera Link is a communication interface for machine vision. The interface extends the underlying technology of Channel Link to provide a specification more useful in this application.
Video Data Signals The Channel Link technology is integral to the transmission of video data. Image data and image enable signals are transmitted on the Chan nel Link bus. Four enable signals are: FVAL-Frame Valid (FVAL) is defined HIGH for valid lines (not used by the CAM/CMOS – 2K.
Power Per the standard, power is not provided on the CameraLink TM connector of the camera. Power is supplied through the Hirose connector. Port Assignments See Tables 3.4.1 for the opt ions of using the CAM/CMOS - 2K.LS with CameraLink TM . In CameraLink TM , a p ort is defined as an 8-bit word as show n in Figure A.
Camera Link Connections -- the MDR 26-Pin Connector The 3M MDR-26 connector was selected for its robust design and reputation for success with high- frequency Channel Link transfer rates ov er several years of experience. The MDR-26 connector is addressed in Section 2.
