1. General

The CV-A11 is a monochrome progressive scan 1/3” CCD cameras, designed for automated inspection application, featuring an extremely small housing and a wide range of unique functions. The asynchronous trigger can be set to work in several modes, to allow functions such as pulse width controlled shutter, programmable shutter speed and long time integration. All mode settings of the camera can be set up via an RS-232C interface, greatly reducing the need for mechanical switches of jumpers. The CV-A11 outputs an analogue video signal, with composite sync.

6. Functions and Operations

Apart from the standard continuous operation, the CV-A11 features three external asynchronous trigger modes (edge pre-select, pulse width controlled and start/stop) and a special frame-delay readout mode. Long integration time mode is also supported. In addition, the CV-A11 also provides a partial scan readout function.

6.1. Basic functions

Some of the primary camera functions need a general introduction before the operation modes are described. The list below shows the primary functions from the command list.

SM Shutter Mode Normal shutter, Programmable Exposure SH Shutter Speed Off to 1/100,000 second PE Programmable Exposure 1.5 H to 1023.5 H SC Scanning Format Full frame, 1/2 partial, 1/3, 1/6 partial TR Trigger Mode Normal, Edge, PWC, frame delay readout Long time exposure, start-stop, smearless (Edge) HC HD Accumulation H Synchronous, H Asynchronous.

The shutter SM can be set to normal (SM=0), where the exposure time is selected from 15 fixed step with the command SH, or programmable exposure (SM=1). Here the command PE allows 1023 step with 1 line period resolution (63.5 µs) in triggered mode. For normal mode, PE can be up to 523 for full, 275 for 1/2, 195 for 1/3 and 115 for 1/6 partial scan. The CCD scanning format SC 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. The partial part of the image is read out with normal speed. The lines below the partial image are read out and dumped with a high speed.

The accumulation mode HC is H synchronous (HC=0). For PWC mode (TR =2) and Frame Delay readout (TR=3) it can also be set to asynchronous accumulation (HC=1). In H synchronous mode, the exposure in will start at the first HD pulse after the trigger falling edge. In H asynchronous mode the exposure will start immediately at the leading edge of the trigger pulse without waiting for the HD. Fig. 9 and fig. 10 shows the details.

In normal continuous mode (TR=0) shutter speed up to 1/100,000 second can be used. In triggered shutter modes, the shortest shutter time is limited to ≥1,5 H or 1/10,000. In triggered shutter modes with full and partial scan, the exposure time is not limited to the frame read out time. It can be longer.

6.2. Input-output of HD/VD Signals

In the default setting the camera will accept external HD/VD signals on pin 6 and 7 of the 12 pin Hirose connector. If external HD/VD is applied, the camera will synchronize to it. If no external sync signals are applied, the camera will operate with its internal x-tal controlled sync. The camera scanning system should be set to the same as the external connected sync. In fig. 11 the time requirements to relation between VD and HD is shown. The input is TTL level as factory setting. It can be 75 Ohm terminated by the internal switch on the PK8299 board. SW2-1 for HD and SW2-2 for VD. On for 75 Ohm termination. To output the internal HD/VD signals on pin 6 and 7 the internal switch SW1-1 and 1-2 on the PK8299 board should be set ON. The output is TTL level from a 75-Ohm source. Refer to “7.4. Internal Switch and Jumper settings.” In trigger modes there are no continuous VD out. Only after an external trigger pulse, a VD pulse will be output.

To use this mode: Set function: SW 1 on PK8299 to IN for external VD/HD input. Factory default. SW 2 on PK8299 to 75 Ω for termination of VD/HD. SW 2 on PK8299 to TTL for TTL level for VD/HD. Factory defaults. SW 1 on PK8299 to OUT for internal VD/HD output. Input: Ext. VD in or int. VD out on pin 7 on 12-pin connector. Ext. HD in or int. HD out on pin 6 on 12-pin connector.

Important notes on using this mode

External sync system should follow the camera scanning system.

Fig. 11. Ext. HD and ext. VD phase conditions.

6.3. Continuous Operation (Non triggered)

For applications that do not require asynchronous external trigger (continuous operation). This is the factory default setting of the camera. See chapter 7.1 on how to select this mode.

To use this mode: Set function: Trigger mode to “Normal” TR=0 Shutter mode “Normal” or “Programmable” SM=0, SM=1 “Shutter Speed” SH=0 through 15 “Programmable exposure” for full scanning PE=1 through 523 PE for 1/2, 1/3 and 1/6 partial scan. < 275, 195, 115 Other functions Input: Ext. VD on pin 7 on 12-pin connector. If used. Ext. HD on pin 6 on 12-pin connector. If used.

6.4. External Trigger Modes

This camera has 6 external asynchronous trigger modes, which can be set by RS-232C commands.

1. Edge Pre-select Mode.TR=1 Pre-selected exposure. (SM=0, SM=1)

2. Pulse Width Control Mode. TR=2 Pulse width controlled exposure. (HC=0, HC=1)

3. Frame Delay read out mode. TR=3 PWC exposure read out by ext. VD. (HC=0, HC=1)

4. Long Time Exposure Mode. TR=4 Exposure is interval between ext. VD.

5. Start/stop Mode. TR=5 Exposure start by trigger and stop by ext. VD

6. Smearless Read out mode. TR=6 EPS Exp. after fast dump readout.(SM=0, SM=1)

The default accumulation is HD synchronously accumulation (HC=0). The accumulation starts at the first HD after the trigger leading edge. Details are shown in fig.15. In PWC mode (TR =2) and Frame Delay readout (TR=3), the accumulation mode HC can be set to asynchronous accumulation (HC=1). The exposure will start immediately at the leading edge of the trigger pulse without waiting for the HD. Fig. 16. below shows the details. In Edge pre-select TR=1 and smearless TR=6, the shutter mode can be SM=0 or SM=1. Smearless read out will reduce the smear caused by highlighted zones seen in images taken with a short shutter speed. Before the accumulation can start, a fast dump read out is performed. It takes 28H from trigger leading edge to start of accumulation.

Important notes on using trigger modes

• The HD synchronized accumulation starts at the first HD after the trigger leading edge. To avoid the <1H jitter caused by this delay, synchronize the external trigger to HD as shown in fig. 14. The trigger level translations should be placed inside A, which is 8 µsec.

• Do not input a new trigger before the previous video is read out. (WEN is high).

6.5. Edge Pre-select Mode

An external trigger pulse initiates the capture (input on pin 11 of the 12-pin Hirose connector or pin 5 of the 6-pin Hirose). The leading edge of the trigger pulse initiates the exposure (this is a falling edge if factory default). If the polarity of this pulse is reversed, the camera can be configured to correct for it. The exposure time (accumulation time) is governed by the predefined shutter speed set by RS-232C.

To use this mode: Set function: Trigger mode “Edge Pre-select” TR=1 Shutter mode to “Normal” or “Programmable” SM=0, SM=1 Shutter Speed using fixed steps SH=0 through 7 or Programmable exposure PE=1 through 1023 Polarity and other functions Input: Ext. trigger to pin 5 on 6 pin connector (or 11 on 12 pin connector) Ext. HD to pin 6 on 12 pin connector. (If used).

Fig. 17. Edge pre-select

Important notes on using this mode:-

• As the start of exposure will be synchronized with the internal H signal, the start of exposure may be shifted by max 1H. To avoid this shift (jitter), synchronize the camera with an external HD and make sure that the trigger pulse aligns to the HD signal as shown in Fig. 14.

• The duration of the external trigger pulse must be greater than 1H. It is recommended to make this longer, typically 9H. This is a TTL level pulse, which can be positive or negative going (the camera can be set to accept any polarity).

• Do not input ext. VD signal at pin 7 on 12 pin connector, as it may disturb the external trigger function.

• Do not input a new trigger before the previous video is read out. (WEN is high).

- 9 -

Page 11

CV-A11

6.6. Pulse Width Control Mode

The leading edge of the trigger pulse initiates the capture. The exposure time (accumulation time) is governed by the duration of the trigger pulse. If the polarity of this pulse is reversed, the camera can be configured to correct for it. The exposure time range is 1.5H to 1000H (shortest and longest pulse duration).

To use this mode: Set function: Trigger mode to “Pulse Width Control” TR=2 HD accumulation HC=0, HC=1 Polarity and other functions Input: Ext. trigger to pin 5 on 6 pin connector (or 11 on 12 pin connector) Ext. HD to pin 6 on 12 pin connector. (If used).

Fig. 18. Pulse width control.

Important notes on using this mode:-

• The exposure will start and stop synchronized to the internal H signal. It result in 1H jitter. To avoid this jitter, synchronize the camera with an external HD and make sure that the trigger pulse aligns to the HD signal as shown in Fig. 14.

• This trigger mode is also supported by a function called “HD Asynchronous Accumulation”, ACSII command “HC”. This function allows integration to start immediately at the leading (falling) edge of the Ext. Trig pulse instead of at the next horizontal drive pulse HD. Please refer to fig. 15 and fig. 16. To enable this function, set HC=1. (Factory default is HC=0). If the falling edge of the trigger falls inside the HD low pulse, a jitter up to 7.5µsec. can be expected. The exposure will start up to 7.5µsec. after the falling edge of the trigger.

• In HD asynchronous PWC mode avoid the trigger to raise inside the HD low period. It will cause 1 line image position jitter.

• Please note that the timing chart in Fig. 18 only shows the HD synchronous mode.

• Do not input external VD signal at Pin No. 7 of the 12-pin Hirose connector, as it may

disturb the external trigger function.

• Do not input a new trigger before the previous video is read out. (WEN is high).

CV-A11

6.7. Frame-delay read out Mode

This mode allows simultaneous capture of multiple camera using a common external trigger pulse subsequent multiplexed (sequential) readout using a single input frame grabber, as the user has control over when the image is read out from the CCD sensor. The exposure starts at the falling edge of the ext. trigger signal, and ends at the rising edge of the ext. trigger signal (in the same way as Pulse Width Control mode). The captured image is now stored in the CCD until an ext. VD signal is given to the camera. The effective video signal is output 14H after the falling edge of WEN signal.

To use this mode: Set function: Trigger mode to “Frame Delay Readout” TR=3 HD accumulation HC=0, HC=1 Polarity and other functions Input: Ext. trigger to pin 5 on 6 pin connector (or 11 on 12 pin connector) Ext. VD to pin 7 on 12 pin connector. Ext. HD to pin 6 on 12 pin connector. (If used).

Fig. 19. Frame delay read out

Important notes on using this mode:-

•

The readout delay time must not exceed 2 seconds. This is because visible dark current noise may appear on the video signal due to the long time exposure of the CCD image sensor.

•

This trigger mode is also supported by a function called “HD Asynchronous Accumulation”, ACSII command “HC”. This function allows integration to start immediately at the leading (falling) edge of the Ext. Trig pulse instead of at the next horizontal drive pulse HD. Please refer to fig. 15 and fig. 16. To enable this function, set HC=1. (Factory default is HC=0). If the falling edge of the trigger falls inside the HD low pulse, a jitter up to 7.5µsec. can be expected. The exposure will start up to 7.5µsec. after the falling edge of the trigger.

•

In HD asynchronous Frame-delay mode avoid the trigger to raise inside the HD low period. It will cause 1 line image position jitter.

•

As the start of exposure will be synchronized with the internal H signal, the start of exposure may be shifted by max 1H. To avoid this shift (jitter), synchronize the camera with an external HD and make sure that the trigger pulse aligns to the HD signal as shown in Fig. 14.

•

It is recommended to use a strobe light (e.g. LEDs or Xenon tube), as the CCD must not be illuminated during readout delay time. The EEN signal can be used to trigger a strobe light

•

See Fig. 11 for the phase relationship between ext. HD and ext. VD pulses.

•

Do not input a new trigger before the previous video is read out. (WEN is high).

- 11 -

Page 13

CV-A11

6.8. Long Time Exposure Mode

The exposure time is the interval between 2 ext. VD pulses sent to the VD input of the camera (Pin No. 7 of the 12-pin Hirose connector). The exposure starts after input of the first ext. VD pulse, and ends after the next input of the next ext. VD pulse, which again starts a new exposure. The long time exposure is a continuous process where each external VD will synchronize the camera, stop on exposure, start a new exposure and read out the previous accumulated signal. The exposure time can be selected in intervals of complete vertical timing periods (=525H).

To use this mode: Set function: Trigger mode to “Long Time exposure” TR=4 Polarity and other functions Input: Ext. trigger to pin 5 on 6 pin connector (or 11 on 12 pin connector) Ext. VD to pin 7 on 12 pin connector. Ext. HD to pin 6 on 12 pin connector.

Fig. 20. Long time exposure.

Important notes on using this mode:-

•

Exposure time range is 1/30 sec. to ∞. However, it is recommended not to use exposure over

2.0 sec. This is because visible dark current noise may appear on the video signal due to the

long time exposure of the CCD image sensor.

•

External sync system should follow the camera scanning system.

•

Ext. HD signal (TTL 2.0~5.0V) has to be input continuously.

•

See Fig. 11 for the phase relationship between ext. HD and ext. VD pulses

•

The EEN pulse is not provided when using this mode.

- 12 -

Page 14

CV-A11

6.9. Start/Stop Mode

The exposure time is controlled by the interval between the ext. trigger and the ext. VD signal. The exposure starts at the first HD pulse after the falling edge of the ext. trigger, and stops at the rising edge of the VD pulse. The range can be between 1/30 to 1/10,000 second. The Start/Stop mode is a continuous mode where the VD signal must be given continuously. It is not possible to input external VD randomly.

To use this mode: Set function: Trigger mode to “Start/Stop” TR=5 Polarity and other functions Input: Ext. trigger to pin 5 on 6 pin connector (or 11 on 12 pin connector) Ext. VD to pin 7 on 12 pin connector. Ext. HD to pin 6 on 12 pin connector. (If used).

Fig. 21. Start/stop mode.

Important notes on using this mode:-

•

Remark that the trigger should be applied up to 15.5 H after the ext. VD for the shortest

•

exposure.

•

External sync system should follow the camera scanning system.

•

See fig. 11 for the relationship between ext. HD and ext. VD.

•

Do not input a new trigger before the previous video is read out. (WEN is high).

6.10. Smearless Mode

This mode will reduce the unwanted smear signal from a highlighted scene when a short exposure time is used. The trigger mode is like edge pre-select, but a fast dump readout is performed before the active accumulation is started. It will remove the smear over the highlighted parts in the image, but there is still smear left below highlighted areas. The trigger leading edge will start the dummy readout. It takes 28 H before the exposure start. The exposure stops and the resulting video signal is read out after the selected shutter time. It can be the 9 first steps normal or 1023 step programmable. SM=0 or SM=1. This mode will operate with full and partial scanning. An EEN pulse will indicate the active accumulation time, and a WEN pulse indicates that the resulting video is read out.

To use this mode: Set function: Trigger mode “Smearless” TR=6 Shutter mode to “Normal” or “Programmable” SM=0, SM=1 Shutter Speed using fixed steps SH=0 through 7 or Programmable exposure PE=1 through 1023 Polarity and other functions Input: Ext. trigger to pin 5 on 6 pin connector (or 11 on 12 pin connector) Ext. HD to pin 6 on 12 pin connector. (If used).

Fig. 22. Smearless mode.

NOTE. Fig. 22 is omitted.

Important notes on using this mode.

• Do not input ext. VD signal at pin 7 on 12 pin connector, as it may disturb the external trigger function.

• Do not input a new trigger before the previous video is read out. (WEN is high).

6.11. Partial scan readout mode

This mode allows increased frame rate, as only a selected number of lines are read out. The vertical resolution is reduced as outlined below. Partial scan will operate in normal continuous mode and all trigger modes.

7.4. Internal Switch and Jumper Settings.

7.4.1. HD/VD input-output selection

In the default setting the camera will accept external HD/VD signals on pins 6 and 7 of the 12 pin Hirose connector. The composite video signal from the camera will be synchronized to an external HD/VD source connected to the camera. TTL level (between 2 and 5 V).

To set up the camera to output HD/VD signals on pins 6 and 7 on the Hirose connector follow these steps

1. Switch off the power to the camera.

2. Remove the camera cover, by removing the 5 screws.

3. Locate switches SW1-1 and SW1-2 on the PK8299 circuit board, and set both in the ON

position. See fig. 26.

Note: The termination of HD/VD output is 75 Ohm.

7.4.2. Selecting termination of HD/VD input signals

The default setting of the HD/VD input is high impedance TTL. The camera expects to get a signal that swings between 2 and 5 volts. This setting allows the largest number of camera to be synchronized from a single HD/VD source (such as another camera or a frame grabber). Under certain circumstances it may be necessary to terminate the HD/VD input, in order to match the impedance of the signal source, to eliminate over/undershoot or standing waves in the signal.

To change the HD/VD input to 75Ohm terminated, follow these steps

1. Switch off the power to the camera.

2. Remove the camera cover, by removing the 6 screws.

3. Locate switches SW2-1 and SW2-2 on the PK8299 circuit board, and set the according

both in the ON position. See fig. 25.

10. Appendix

10.1. CV-A11 emulating CV-M10 interfacing

The CV-A11 has a slightly different pin configuration on the 12-pin Hirose connector, compared to the M-series. This new configuration is compliant to the EIA-J standard. This means, however, that the CV-A11 is not completely backward compatible with the CV-M10, CV-M40, etc in all cases (depending on the cable configuration). The table below shows how to change the pin configuration, by changing internal solder jumpers. Please note: Only a qualified electronics technician or engineer should make these changes.

10.2. Precautions

Personnel not trained in dealing with similar electronic devices should not service this camera. 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. Do not expose this camera to rain or moisture. Do not face this camera towards the sun, extreme bright light or light reflecting objects. When this camera is not in use, put the supplied lens cap on the lens mount. Handle this camera with the maximum care. Operate this camera only from the type of power source indicated on the camera. Power off the camera during any modification such as changes of jumper and switch setting.

10.3. Typical CCD Characteristics

The following effects may be observed on the video monitor screen. They do not indicate any fault of the CCD camera, but do associate with typical CCD characteristics.

V. Smear

Due to an excessive bright object such as electric lighting, sun or strong reflection, vertical smear may be visible on the video monitor screen. This phenomenon is related to the characteristics of the Interline Transfer System employed in the CCD.

V. Aliasing

When the CCD camera captures stripes, straight lines or similar sharp patterns, jagged image on the monitor may appear.

Blemishes

Some pixel defects can occur, but this does not have an effect on the practical operation.

Patterned Noise

When the CCD camera captures a dark object at high temperature or is used for long time integration, fixed pattern noise (shown as white dots) may appear on the video monitor screen.
