Standard Composition The standard camera composition consists of the camera main body and tripod mount plate.

SW301.1. Factory setting is CL. The 26 pin MDR connector pin assignment follows the Camera Link base configuration. For a detailed description of Camera Link specifications, please refer to the Camera Link standard specifications found on www.jai.com CV-A33 Camera CV-A33 Camera Camera Link Cable...
CV-M9 CL 5.3.5. Bit allocation in Camera Link connectors The CV-M9CL camera has outputs for the RGB signals in Camera Link. The RBG output can be allocated as 3 x 8 bit in Camera Link base configuration. Connector 1 is then used. For 3 x 10 bit RGB output in Camera Link, 2 connectors are used in medium configuration.
CV-M9 CL 6. Functions and Operations 6.1. Basic functions A 16-bit processor controls all functions in the CV-M9CL camera. The CCD sensor output is normalized in preamplifiers. The signals are then digitized to 12 bits. Digital gain control and look-up tables can do signal processing in 12 bits before it is truncated to a 10 or 8 bit camera link signal.
CV-M9 CL 6.1.2. Knee function The internal video signal is 12 bit, and only 8 or 10 bit is output. By help of the look-up table function it is possible to compress or expand the video signal to change the dynamic range. It can be done individually for R, G and B with the knee function.
CV-M9 CL 6.2. Sensor Layout and timing 6.2.1. CCD Sensor Layout Fig. 13. CCD sensor layout Table for scanning. The below table shows the start line, the stop line and the number of active lines in the vertical centred scanned area on the CCD sensor. The front and back lines are the lines used for the fast dump readout used in partial scanning.
CV-M9 CL 1L = 50.96 µs Fig. 20. Vertical timing for V binning. 6.3. Input/Output of Timing Signals For settings, please refer to chapter “7. Configuring the Camera” 6.3.1. Input of external trigger Input of external trigger signal can be via Camera Link (TI=0). Factory setting. Or as TTL on the 12 pin connector pin 10.
CV-M9 CL 6.4.1. LVAL synchronous accumulation With LS=0, the accumulation will start synchronously with LVAL. The trigger pulse should be longer than 2 LVAL intervals, and the accumulation will then start at the first LVAL after the trigger leading edge. The exposure start delay will be up to 1 line. (42.07 µsec.). In EPS mode the exposure stops 0.5 L after the selected shutter time, (in number of LVAL).
CV-M9 CL 6.4.2. LVAL a-synchronous accumulation With LS=1, the accumulation will start immediately after the trigger leading edge. The exposure start delay is 9.7 µsec. In EPS mode the exposure stops 0.5 L after the selected shutter time, (in number of LVAL). In PWC mode the exposure stops 0.5 L after the trigger trailing edge.
CV-M9 CL 6.4.3. Continuous operation For applications not requiring asynchronous external trigger, but should run in continuous operation, this mode is used. In this mode it possible to use a lens with video controlled iris. For timing details, refer to fig. 13. through fig. 20. To use this mode: Set function: Trigger mode to “Continuous”...
CV-M9 CL 6.4.4. Edge Pre-select Trigger Mode An external trigger pulse initiates the capture, and the exposure time (accumulation time) is the fixed shutter speed set by SH or PE. The accumulation can be LVAL synchronous or LVAL a- synchronous. The resulting video signal will start to be read out after the selected shutter time.
CV-M9 CL 6.4.5. Pulse Width Control Trigger Mode In this mode the accumulation time is equal the trigger pulse width. Here it is possible to have long time exposure. The maximum recommended time is <2 seconds. The accumulation can be LVAL synchronous or LVAL a-synchronous. The resulting video signal will start to be read out after the trigger rising edge.
CV-M9 CL 6.4.6. Reset Continuous Trigger mode The RCT mode is in principle the same as normal continuous mode. The difference is that an external trigger pulse will immediately stop the video read out and reset and restart the vertical timing.
CV-M9 CL 6.4.7. Sensor Gate Control This function is for applications with strobe flash illuminations or long time accumulations up to several frames. The external Sensor Gate control signal will disable the internal SG pulse so the accumulation will continue during the next frame. As long as the sensor gate control signal is low, the accumulation will continue.
CV-M9 CL 6.5. Other Functions. Scanning. SC=0 through 3. 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.

CV-M9 CL RCT FVAL type. RF=0, RF=1. This command selects the FVAL type in RCT mode. Refer to chapter 6.4.6. Reset Continuous Trigger mode. Trigger input select. TI=0, TI=1. This function selects the trigger input to be through Camera Link (TI=0), or as TTL through the 12 pin Hirose connector (TI=1).

CV-M9 CL Knee function. KN=0, KN=1. If KN=1 is received the knee function is enabled. With the knee functions is possible to change the relation between CCD signal and the resulting output video signal. With the function disabled, the transfer slope is 1:1. The level where the slope should be changed is set with the knee point settings.
CV-M9 CL 6.5.1. Customized shading correction. From factory, the CV-M9CL camera is delivered with a shading correction adjusted to work with homogeny lightening coming from a DC regulated halogen lamp at 3200K and a certain Fujinon lens. This shading data stored in the factory area is also used for the 3 user areas. For other fixed illumination and for another fixed lens in a specific setup, it makes sense to make a temporary customized shading calibration.
CV-M9 CL 6.6. Request Functions. The following commands are for identification and help. Fig. 33. shows some printout examples from a PC running terminal emulator software. (Hyper terminal). Status, version, camera ID, model name, user ID and the help list are shown. Please refer to chapter 7.2.
