Page 9: Functions And Operations
CV-M4 CL, CV-M7 5.5. CV-M4 Block Diagram Fig. 9. Block diagram for the camera 6. Functions and Operations 6.1. Basic functions The CCD scanning format can be selected between full or partial scanning. With partial scanning only the vertical central part of the CCD sensor is read out with a higher frame rate. The partial scan is done by a fast dump read out of the lines in the vertical ccd register down to the top of the partial image. - Page 10 Binning mode is a function where the signal charge from 2 or more adjacent pixels are added together and read out as one pixel. A resulting full frame with lower spatial resolution can be read out with a higher rate, and higher sensitivity. The CV-M4 pixel charge from 2 adjacent lines are added together in the horizontal ccd register.
- Page 11 Color versions CV-M7 and CV-M7 These color cameras are identical to the monochrome cameras. Only the CCD sensor is changed to a RGB primary color type. Here the color mosaic lay out is shown in fig. 13. left. This lay out is known as a Bayer filter.

Page 13: Continuous Operation (Non Triggered)
6.3. Continuous Operation (Non triggered) Mode settings can be done with either RS-232C or switches. Trigger Mode Normal. TR=0. It is for applications where the camera is continuous running without external trigger. The shutter mode can be normal or programmable exposure. (SM=0, SM=1). The shutter will work in all 10 steps up to 1/10,000 second or with the programmable exposure in 1056 steps. - Page 14 CV-M4 CL, CV-M7 Fig. 17. Vertical timing details, full frame. Fig. 17A.

Page 16: External Trigger Modes
6.4. External Trigger Modes This camera has 3 external asynchronous trigger modes, which can be set by RS-232C commands or switches. Edge Pre-select Mode. TR=1 Pulse Width Control Mode. TR=2 Frame Delay read out mode. TR=3 The trigger can be H synchronous (HC=0) or H a-synchronous (HC=1). Refer to fig. 12. In H synchronous mode, the accumulation will start at the first H (LEN) after the trigger leading edge. -
Page 17: Edge Pre-Select Mode
6.5. Edge Pre-select Mode The trigger leading edge will start the exposure H synchronous or H a-synchronous (HC=0, HC=1). The exposure stops and is read out after the shutter time selected. It can be the 10 steps in normal or 1056 steps in programmable. SM=0 or SM=1. This mode will operate with full and partial scanning and with V-binning (M4 combinations is not allowed. - Page 18 CV-M4 CL, CV-M7 Remark that the dump read out in smearless takes 133H before the accumulation start.

Page 19: Pulse Width Control Mode
6.6. Pulse Width Control Mode In this mode the exposure starts from the leading edge of the trigger pulse, H synchronous or H a-synchronous. It stops at the trailing edge of the trigger pulse, and the resulting video is read out. -
Page 20: Frame-Delay Read Out Mode
6.7. Frame-delay read out Mode In this mode the pre selected exposure starts from the leading edge of the trigger pulse, H synchronous or H a-synchronous. It can be the 10 steps in normal or 1056 steps in programmable. SM=0 or SM=1. The resulting video is read out at the trailing edge of the trigger. This mode will operate with full and partial scanning and with V binning (M4 Partial scanning and binning in combinations is not allowed. -

The camera contains components sensitive to electrostatic discharge. The handling of these devices should follow the requirements of electrostatic sensitive components. Do not attempt to disassemble this camera. -
Page 30: Camera Link Test Points
10.3. Camera Link Test points Inside the camera Link versions cameras CV-M4+CL and CV-M7+CL there are some useful test points, which can be a big help in system troubleshooting. The timing signals are multiplexed into the Camera Link, so it is not possible to use an oscilloscope to control the timing for a camera frame grabber system. -
