How to get started (CameraLink®)
1. Install a suitable frame grabber in your PC.
To find a compliant frame grabber, please see the frame grabber compatibility
list at www.photonfocus.com.
2. Install the frame grabber software.
✎
Without installed frame grabber software the camera configuration tool PFRe-
mote will not be able to communicate with the camera. Please follow the in-
structions of the frame grabber supplier.
3. Remove the camera from its packaging. Please make sure the following items are included
with your camera:
• Power supply connector (7-pole power plug)
• Camera body cap
If any items are missing or damaged, please contact your dealership.
4. Remove the camera body cap from the camera and mount a suitable lens.
When removing the camera body cap or when changing the lens, the camera
should always be held with the opening facing downwards to prevent dust or
debris falling onto the CMOS sensor.
Figure 2.1: Camera with protective cap and lens.
Do not touch the sensor surface. Protect the image sensor from particles and
dirt!
9

2 How to get started (CameraLink®)
To choose a lens, see the Lens Finder in the ’Support’ area at
www.photonfocus.com.
5. Connect the camera to the frame grabber with a suitable CameraLink®cable (see Fig. 2.2).
CameraLink®cables can be purchased from Photonfocus directly (www.photonfocus.com).
Please note that Photonfocus provides appropriate solutions for your advanced vision
applications.
Figure 2.2: Camera with frame grabber, power supply and cable.
Do not connect or disconnect the CameraLink®cable while camera power is on!
For more information about CameraLink®see Section 4.12.
6. Connect a suitable power supply to the provided 7-pole power plug. For the connector
assembly see Fig. A.1. The pinout of the connector is shown in Appendix A.
Check the correct supply voltage and polarity! Do not exceed the maximum
operating voltage of +12V DC (±10%).
7. Connect the power supply to the camera (see Fig. 2.2).
✎
The status LED on the rear of the camera will light red for a short moment, and
then flash green. For more information see Section 5.1.4.
8. Download the camera software PFRemote to your computer.
You can find the latest version of PFRemote on the support page at
www.photonfocus.com.
10

9. Install the camera software PFRemote. Please follow the instructions of the PFRemote
setup wizard.
Figure 2.3: Screen shot PFremote setup wizard
10. Start the camera software PFRemote and choose the communication port.
Figure 2.4: PFRemote start window
11. Check the status LED on the rear of the camera.
✎
The status LED lights green when an image is being produced, and it is red when
serial communication is active. For more information see Section 5.1.4.
12. You may display images using the software that is provided by the frame grabber
manufacturer.

Product Specification
3.1 Introduction
The MV1-D1312C CMOS camera series are built around the colour A1312C CMOS image sensor
from Photonfocus, that provides a resolution of 1312 x 1082 pixels at a wide range of spectral
sensitivity. It is aimed at standard applications in industrial image processing.
The principal advantages are:
• Resolution of 1312 x 1082 pixels.
• Bayer pattern filter and cut off filter @ 660nm
• High quantum efficiency (between 25% and 45%).
• High pixel fill factor (> 60%).
• Superior signal-to-noise ratio (SNR).
• Low power consumption at high speeds.
• Very high resistance to blooming.
• High dynamic range of up to 120 dB.
• Ideal for high speed applications: Global shutter.
• Colour resolution of up to 12 bit.
• On camera shading correction.
• Up to 512 regions of interest (MROI).
• 2 look-up tables (12-to-8 bit) on user-defined image region (Region-LUT).
• Image information and camera settings inside the image (status line).
• Software provided for setting and storage of camera parameters.
• The camera has a digital CameraLink®interface.
• The compact size of 60 x 60 x 45 mm3makes the MV1-D1312C CMOS cameras the perfect
solution for applications in which space is at a premium.
The general specification and features of the camera are listed in the following sections.
This manual applies only to MV1-D1312C cameras with revision 2.0 or higher.
The camera revision information is displayed as uC Revision in the Info tab of the
PFRemote application.

Fig. 3.2 shows the quantum efficiency and Fig. 3.3 the responsivity of the A1312C CMOS sensor,
displayed as a function of wavelength. For more information on photometric and radiometric
measurements see the Photonfocus application notes AN006 and AN008 available in the
support area of our website www.photonfocus.com.
The A1312C colour sensor is equipped with a cover glass. It incorporates an infra-red cut-off
filter to avoid false colours arising when an infra-red component is present in the illumination.
Fig. 3.4 shows the transmssion curve of the cut-off filter.
3.4 RGB Bayer Pattern Filter
Fig. 3.5 shows the bayer filter arrangement on the pixel matrix in the MV1-D1312C camera
series. The numbers in the figure represents pixel position x, pixel position y.
The fix bayer pattern arrangement has to be considered when the ROI configu-
ration is changed or the MROI feature is used (see 4.3). It depends on the line
number in which an ROI starts. An ROI can start at an even or an odd line num-
ber.
