CV-A10 CL and CV-A70 CL 1. General This manual will cover the digital monochrome progressive scan camera CV-A10 CL, and its color version, CV-A70 CL. The CV-A10CL is a Camera Link successor for the CV-M10BX/RS cameras. The progressive scanned CV-A10CL has a single digital video output as Camera Link. The frame rate for full frame is 60 fps. Functions like partial scanning and horizontal and vertical binning allows higher frame rates.

CV-A10 CL and CV-A70 CL 5.3. Input and output circuits In the following schematic diagrams the input and output circuits for video and timing signals are shown. 5.3.1. Iris video output This signal can be used for lens iris control in Continuous and Reset Continuous Trigger mode. The signal is taken from the CCD sensor output before the gain circuit. The video output is without sync. The signal is 0.7 Vpp from <400 Ω ac coupled. Do not use auto shutter (CCD iris) when auto iris lens is used.
CV-A10 CL and CV-A70 CL 5.3.5. 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.
CV-A10 CL and CV-A70 CL 6. Functions and Operations 6.1. Basic functions The A10CL-A70CL camera is a progressive scan camera with 10 or 8 bit video output in single channel Camera Link. An analogue iris video signal can be used for lens iris control. The camera has 1/2, 1/4 or 1/8 partial scanning for faster frame rates. Vertical and horizontal binning is possible. The H and V binning can operate separate or together. 2:1, 3:1 a 4:1 binning is available.
CV-A10 CL and CV-A70 CL 6.1.3. CV-A10 CL. Binning H Binning is only on CV-A10 CL. The binning functions can be used for higher frame rate or for higher sensitivity. The drawback is lower resolution. Vertical binning is done by adding the charge from pixels in adjacent lines in the horizontal ccd register. Horizontal binning is done by adding the charge from adjacent pixels in the sample/hold circuit capacitor. In horizontal binning, the pixel clock will not change, so the grabber will over sample.

Input of External HD/VD signals External synchronizing is only possible in full and partial scanning. For trigger mode only ext. HD can be input. HD and VD input pins are shared with the RS-232C interface, which is factory default. SW301.2 (HD/RxD) and SW301.3 (VD/TxD). The video output is synchronized with external HD/VD signals if applied.

Input of external trigger The external trigger signal can be via Camera Link (TI=0), or pin 10 on 12 pin connector. (TI=1). Here it should be 4.0 Vp-p ±2.0 V from a 75 Ω source. Factory setting TTL. For 75 Ω termination SW302.1 should be ON. 6.3.3.
CV-A10 CL and CV-A70 CL 6.4. Operation Modes This camera can operate in 5 primary modes. 1. 2. 3. 4. 5. TR=0 TR=1 TR=2 TR=3 TR=10 Normal continuous Mode. Edge Pre-select Mode. Pulse Width Control Mode. Sensor Gate Control Reset Continuous Trigger Pre-selected exposure. Pre-selected exposure. Pulse width controlled exposure. Strobe illuminated exposure with delayed read out Pre-selected exposure. The triggered shutter in EPS, PWC and RTC mode can be LVAL synchronous or LVAL asynchronous accumulation.
CV-A10 CL and CV-A70 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, 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. (26.7 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 first LVAL after the trigger trailing edge.
CV-A10 CL and CV-A70 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 will be 4 µsec. for shutter speeds up to 1/75,000. 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. A new trigger must not be applied before the previous frame is read out. (FVAL is low).
CV-A10 CL and CV-A70 CL 6.4.3. Continuous operation For applications not requiring asynchronous external trigger, but should run in continuous operation, this mode is used. For timing details, refer to fig. 13. through fig. 17. To use this mode: Set function: Input: Trigger mode to “Continuous”. Scanning Vertical binning. (CV-A10 CL only) Horizontal binning. (CV-A10 CL only) Shutter mode normal, programmable or auto Shutter speed Programmable exp. Other functions and settings Ext.
CV-A10 CL and CV-A70 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 asynchronous. The resulting video signal will start to be read out after the selected shutter time. To avoid up to 1LVAL time jitter in LVAL synchronous accumulation it is recommended to synchronize the trigger to HD. (See fig. 23.).
CV-A10 CL and CV-A70 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 <120 frames. The accumulation can be LVAL synchronous or LVAL a-synchronous. To avoid up to 1LVAL time jitter in LVAL synchronous accumulation it is recommended to synchronize the trigger to HD. (See fig. 23.). Use LVAL synchronous accumulation (LS=0) for highest trigger rate.
CV-A10 CL and CV-A70 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. After a fast dump read out, which takes 86 LVAL, a new triggered exposure is started and read out as normal. If no further trigger pulses are applied, the camera will continue in normal mode.
CV-A10 CL and CV-A70 CL 6.4.7. Sensor Gate Control This mode is for applications with strobe flash illuminations or long time accumulations up to several frames. In this mode the camera is running continuously. The external Sensor Gate control signal will disable the internal XSG pulse so the accumulation will continue during the next frame. The resulting video is read out after the first FVAL (or SG), following the trailing edge of the Sensor Gate Control signal.
CV-A10 CL and CV-A70 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. This central part of the image is read out with normal speed.
CV-A10 CL and CV-A70 CL Gain settings. AS=0, AS=1. The video gain can be selected between manual gain (AS=0), or AGC (AS=1). Manual gain is set by the gain level command GA=. The reference level for the AGC is set by the AGC reference level AG=. In AGC mode the video level is kept constant by the automatic gain control circuit within a 15 dB range. For CV-A70CL 12 dB. Together with the auto shutter function it will keep the video output constant over a wide range of illumination.
