CV-A33CL 1. General The CV-A33CL is a digital CMOS camera designed for automated imaging applications, featuring high speed within a uniform and compact housing. The high-speed shutter function, asynchronous random trigger mode and partial scan mode, with window of interest, allows the camera to capture high quality images of fast moving objects with a high frame rate. The CV-A33CL features the Camera Link standardized multiplexed signal output interface.

CV-A33CL 5.3. Input and Output Circuits 5.3.1. Trigger input The trigger inputs on pin #10 12 pin Hirose connector is AC coupled. To allow a long pulse width, the input circuit is a flip flop, which is toggled by the negative or positive differentiated spikes caused by the falling or rising trigger edges. The trigger polarity can be changed. Trigger input level 4 V ±2 V. It can be 75Ω terminated by internal SW300 on PK8388A. The trigger inputs can be changed to Camera Link input.
CV-A33CL 5.3.3. Camera Link interface The video output is Camera Link with 10 or 8 bit video placed in a base configuration. The digital output signals follow the Camera Link standardized multiplexed signal output interface. The Camera Link output driver is NS type DS90CR285MTD. The data bits from the digital video, FVAL, LVAL, DVAL and EEN are multiplexed into the twisted pairs, which are a part of the Camera Link. Trigger signals and the serial camera control are feed directly through its own pairs.
CV-A33CL 6. Functions and Operations In the following the format shown in “7.3. CV-A33CL command list” are used for function commands and parameters. 6.1. Basic functions The CV-A33CL camera is a progressive scan camera with 10 or 8 bit video output in single channel Camera Link. Programmable partial scan, where the start line and the number of lines can be selected with 1 line increment is also available.
CV-A33CL 6.1.3. Column Process The voltage signal from a single pixel is send to the Columns column amplifier trough the 4 to 1 multiplexer. After 10 bit the S/H circuit, the offset and gain calibrating is video To shift Offset Register perform. A 10 bit A/D converter send the digital pixel Amp S/H Gain A/D through calibr 1 to 4 signal to the digital horizontal shift register by a 1 to 4 multiplex multiplexing.
CV-A33CL 6.1.6. Window of Interest If a higher frame rate is wanted, it is possible to change the CMOS sensors sensing area to the window of interest. WS =1 for windows scan. The X,Y start coordinate, the window width and height can be programmed. WX can be in the range 0 to 657 WY can be in the range 0 to 490 WW can be in the range 2 to 659. (WX + WW ≤ 659) WH can be in the range 3 to 493. (WY + WH ≤ 493) The frame rate will not increase if the width WW is reduced.

CV-A33CL 6.2.4. LVAL a-synchronous accumulation The CV-A33CL has LVAL a-synchronous accumulations only. The accumulation will start 28 µsec. after the trigger leading edge. EEN will indicate the accumulation time. When the accumulation stops after the selected shutter time, the LVAL phase is reset and restarted. 1 LVAL = 16.825 µsec. 16.8 µsec. LVAL Trigger Accum Delay 28 µsec. EEN Fig. 16.
CV-A33CL 6.2.5. Timing for window of interest With WS=1, the X and Y start coordinates (WX and WY), and the width and height (WW and WH) for the window of interest can be programmed with 1 pixel interval. The minimum window size is 2(h) x 3 (v). If the window is specified outside the full image area, it will be placed up to the right or low limit as shown in fig 17. right. Figures marked with (*) in the timing diagrams below will change with other window settings.
CV-A33CL 6.3. Input/Output of Timing Signals 6.3.1. Input of Timing Signals It is not possible to synchronize the camera from an external sync source except by an extern trigger pulse. The camera will always run with its internal X-tal controlled timing. Trigger input through Camera Link. TI=0 Trigger input as TTL on pin #10 on 12 pin Hirose. TI=1 The trigger polarity is active low. TP=0 Trigger input can be changed to active high.
CV-A33CL 6.4.1. Continuous Operation (Non triggered) Mode settings can be done with RS-232C. 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 8 steps up to 1/20,000 second or with the programmable exposure in 2 to 493 steps. In programmable exposure the actual exposure is 1 LVAL less than the PE value.

CV-A33CL 6.4.3. Pulse Width Control Mode The exposure will start 28 µsec. after the trigger leading edge, and it stops and is read out at the trigger trailing edge. This mode will operate with full window or windows of interest scanning. An EEN pulse will indicate the active accumulation time, and a FVAL pulse indicates that the resulting video is read out.
CV-A33CL 6.4.4. Auto trigger Mode The auto trigger function, TR=3 can be used as sensing device inside the camera field of view. It sense in a programmable window from top of the image. The continuous output is sent to the frame grabber, which PC should be programmed to sense if an object is passing the window. The horizontal position and the signal threshold could be the programmed parameters. If an object passing is detected, a trigger is send to the camera.
CV-A33CL 6.5. Other Functions. User ID. The command (UD) the user can save up to 16 characters in the camera to identify the camera. Bit Allocation. The command (BA) will select the number of bits in the Camera Link output to 8 or 10 bit. Black Level. The command (BL) is for adjusting the video black level (or set-up level). GAin level. The command (GA) is for adjusting the gain level between 0 and 15 dB. CaliBration of CMOS sensor.
CV-A33CL 7.2. RS-232C control All configuration of the CV-A33CL camera is done via the RS-232C port on the 12 pin HR connector or via Camera Link. (Internal switch SW200 off for HR).
