Iris video output

A video signal for lens iris control is found on pin 4. 12-pin connector. The signal is with composite sync. It is ac coupled from a 75Ω source. It can only be used for iris control in normal continuous mode.

Fig. 6. Video outputs

Trigger input

The trigger input is AC coupled. To allow a long wide pulse width, the input circuit is a flip-flop, which is toggled by the negative and positive differentiated spikes cause buy the falling and rising edge. The input signal level is 4V ± 2V. The trigger input impedance is 1.2 kΩ or 75Ω selectable via the internal switch S301-3.

Fig. 7. Trigger input

HD and VD input

The HD and VD input circuit can be 75Ω terminated via the internal switch S301-1 and S301-2. The input signal level is 4V ± 2V.

6. Functions and Operations

6.1. Basic operation modes

Apart from the standard continuous operation mode, the CV-M77 features four external triggering modes and a long time exposure mode. In all modes the camera can be synchronized to an external sync. The shutter time can be selected from 12 fixed steps, or from 788 steps with 1H resolution. In triggered mode it can also be controlled by the trigger pulse width. The frame delayed readout can operate in either edge pre-selected trigger, or pulse width controlled shutter mode.

Switches can set most modes and functions locally. All modes and functions can be remote controlled by RS-232C control. Alternative connections for input and output signals can be done by internal jumpers.

For details: refer to “7. Configuring the Camera”.

6.1.1. High frame rate.

From revision C, the CV-M77 camera has a new readout mode. It is the high frame rate mode. Here only every third line is read out. The 2 lines between are dumped. In this way the Bayer RGB mosaic pattern is unchanged. The DSP interpolation algorithm for RGB color output can still be used. The figures below shows the CCD sensor in normal mode and high frame rate mode. In high frame rate, the vertical ccd register is clocked with 3 times higher rate. But only the signals from every third line is transferred to the horizontal ccd register for read out. Signals from the lines between are dumped. The horizontal resolution is unchanged, but the vertical resolution is reduced to 1/3.

The advantages are:

 Frame rate 3 times higher  The image is sampled from the whole sensor area  Horizontal resolution unchanged

6.2. Input/Output of HD/VD Signal

6.2.1. Input of External HD/VD signals

This setting is factory pre-set. The video output is synchronized with external HD/VD signals if applied. If no ext. HD signal is input, the camera will switch to the internal X-tal controlled HD sync. If no ext. VD is connected, the camera will continue with its internal VD. For details: refer to “7. Configuring the Camera”.

To use this mode: Set function: SW 303.1 and 303.2 to ON for external HD/VD input. Factory default. SW 301.1 and 301.2 to OFF for TTL level for HD/VD. Factory defaults SW 301.1 and 301.2 to ON for 75 Ω termination of HD/VD.. Input: Ext. HD in on pin 6 on 12-pin connector. 4.0 Vp-p ±2.0V. Ext. VD in on pin 7 on 12-pin connector. 4.0 Vp-p ±2.0V.

Important notes on using this mode

External sync system should follow the camera scanning system.

The ext. HD/VD phase relations should follow as shown in fig. 10.

6.3. Continuous operation

This mode is used for applications that do not require asynchronous external trigger, but run in continuous operation. Mode setting and all other settings can be done via RS 232C control if rear switch SW1-10 is ON. Mode setting and some other settings can be done by switch if rear switch SW1-10 is OFF. For details: refer to “7. Configuring the Camera”.

To use this mode: RS SW1- Set function: Trigger mode to “Normal” TR=0 5, 6, 7 OFF Shutter to “Normal” or “Programmable” SM=0, SM=1 “Shutter speed” SH=0 through 11 1, 2, 3, 4 “Programmable exposure” PE=3 through 791 Other functions Input: Ext. HD in on pin 6 on 12-pin connector. 4.0 Vp-p ±2.0V. (If used). Ext. VD in on pin 7 on 12-pin connector. 4.0 Vp-p ±2.0V. (If used).

Important notes on using this mode

6.4. Trigger modes

The CV-M77 camera features 4 external triggering modes:

1 Edge Pre-Select. (EPS). Asynchronous reset and exposure start by an ext. trigger pulse. 2 Pulse Width Control. (PWC). Exposure control by the low period of the ext. trigger pulse. 3 Readout Delay EPS. Triggered EPS exposure. Readout controlled by external VD signal. 4 Readout Delayed PWC. Triggered PWC exposure. Readout controlled by external VD signal.

These external triggering modes operate with H non-reset. In H non-reset, the exposure will be synchronized to the internal HD, and the exposure will start at the first HD after the negative going edge of the trigger. Refer to fig. 13. The exposure stops 0.5 H after the last HD pulse. To avoid the <1H exposure jitter caused by this delay, it is recommended to synchronize the external trigger to HD as shown in fig. 14.

The trigger input can be TTL level or 75 ohm terminated by setting the specific S301 switch on the PK 8308 board to OFF or ON (see switch settings). When 75 ohm terminated the signal input level is 4.0 Vp-p ±2.0V.

Mode setting and all other settings can be done via RS 232C control if rear switch SW1-10 is ON. Mode setting and some other settings can be done by switch if rear switch SW1-10 is OFF.

For details: refer to “7. Configuring the Camera”.

Important notes on using this mode

Number of effective pixels per line in trigger modes are 1016 (h).

CV-M77

6.4.1. Edge Pre-select Trigger

This trigger mode operates in H non-reset mode. In H non-reset mode the exposure will start at the first internal HD after the trigger. The trigger input should be longer than or equal to 2 HD (102 µsec.). The external trigger pulse initiates the capture, and the exposure time (accumulation time) is governed by the fixed shutter speed set up by the rear panel DIP-switches or via RS-232C control. The EEN pulse indicates the actual exposure time. The resulting video signal will start to be read out after the selected shutter time. The WEN pulse indicates the start of valid video signal. Refer to timing charts for details. A new trigger pulse must not be applied before the video read out has finished. If the camera is synchronized to an external HD signal, there are some requirements to the phase between the ext. HD and the Ext. trigger. The falling edge of the trigger should be less than 8 µsec before the falling edge of the ext. HD and less than 2 µsec after the falling edge of the ext. HD (see fig. 14.). Otherwise the jitter will be too high.

Mode setting and all other settings can be done via RS 232C control if rear switch SW1-10 is ON. Mode setting and some other settings can be done by switch if rear switch SW1-10 is OFF. For details: refer to “7. Configuring the Camera”.

To use this mode: RS SW1- Set function: Trigger mode to “Edge Pre-Select” TR=1 5 ON, 6, 7 OFF Shutter to “Normal” or “Programmable” SM=0, SM=1 “Shutter speed” SH=0 through 11 1, 2, 3, 4 “Programmable exposure” PE=3 through 791 Polarity and other functions Input: Ext. trigger in on pin 5 on 6-pin con. (Or 11 on 12 pin). 4.0 Vp-p ±2.0V. Ext. HD in on pin 6 on 12-pin connector. 4.0 Vp-p ±2.0V. (If used).

Important notes on using this mode

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

• The trigger pulse width should be >2H to <2000H.

• A new trigger must not be applied before WEN is high.

CV-M77

6.4.2. Pulse Width Control Trigger

This trigger mode where the length of the trigger pulse determines the exposure time operates in H non-reset mode. In H non-reset mode the trigger pulse and the HD signal are synchronized. The exposure will start at the first HD pulse after the falling edge of the external trigger signal. The exposure ends 0.5 H after the HD following the rising edge of the external trigger signal. The trigger pulse must be longer than >1H (51µsec) and shorter than 2000 H. To avoid jitter the camera should be synchronized to an external HD. There are some requirements to the phase between the ext. HD and the Ext. trigger. The falling edge of the trigger should appear in the interval less than 8 µsec before the falling edge of the ext. HD and less than 2 µsec after the falling edge of the ext. HD and the rising edge off the trigger should be fall in the interval 8 µsec before the rising edge of the ext. HD and 2 µsec after rising edge of the ext. HD. (See figure

14.). The EEN pulse indicates the actual exposure time. The resulting video signal will start to be read out after the rising edge of the external trigger signal. The WEN pulse indicates the start of valid video signal. Refer to timing charts for details. A new trigger pulse must not be applied before the video read out has finished.

Mode setting and all other settings can be done via RS 232C control if rear switch SW1-10 is ON. Mode setting and some other settings can be done by switch if rear switch SW1-10 is OFF. For details: refer to “7. Configuring the Camera”.

To use this mode: RS SW1- Set function: Trigger mode to “Pulse Width Control” TR=2 1, 2 ON, 3 OFF Polarity and other functions Input: Ext. trigger in on pin 5 on 6-pin con. (Or 11 on 12 pin). 4.0 Vp-p ±2.0V. Ext. HD in on pin 6 on 12-pin connector. 4.0 Vp-p ±2.0V. (If used).

Important notes on using this mode

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

6.4.3. Frame Delay Readout EPS

This trigger mode operates in H non-reset mode. In H non-reset mode the exposure will start at the first internal HD after the trigger. The trigger input should be longer than or equal to 2 HD (102 µsec.). The external trigger pulse initiates the capture, and the exposure time (accumulation time) is governed by the fixed shutter speed set up by the rear panel DIP-switches or via RS-232C control. The EEN pulse indicates the actual exposure time. The resulting video signal will first start to be read out after the input of an external VD signal. The readout delay should not be to long due to visible dark current noise generated in the CCD sensor. The WEN pulse indicates the start of valid video signal. Refer to timing charts for details. A new trigger pulse must not be applied before the video read out has finished. If the camera is synchronized to an external HD signal, there are some requirements to the phase between the ext. HD and the Ext. trigger. The falling edge of the trigger should be less than 8 µsec before the falling edge of the ext. HD and less than 2 µsec after the falling edge of the ext. HD (see fig. 14.). Otherwise the jitter will be too high.

Mode setting and all other settings can be done via RS 232C control if rear switch SW1-10 is ON. Mode setting and some other settings can be done by switch if rear switch SW1-10 is OFF. For details: refer to “7. Configuring the Camera”.

To use this mode: RS SW1- Set function: Trigger mode to “Fame Delayed readout EPS” TR=3 1 ON, 2 OFF, 3 ON Shutter to “Normal” or “Programmable” SM=0, SM=1 “Shutter speed” SH=0 through 11 1, 2, 3, 4 “Programmable exposure” PE=3 through 791 Polarity and other functions Input: Ext. trigger in on pin 5 on 6-pin con. (Or 11 on 12 pin). 4.0 Vp-p ±2.0V. Ext VD on pin 7 on 12 pin con. (Or 1 on 9 pin ). 4.0 Vp-p ±2.0V. Ext. HD in on pin 6 on 12-pin connector. 4.0 Vp-p ±2.0V. (If used).

6.4.4. Frame Delay Readout PWC

This trigger mode operates in H non-reset mode. In H non-reset mode the trigger and HD is synchronized. The exposure will start at the first HD pulse after the falling edge of the external trigger signal. The exposure ends 0.5 H after the HD following the rising edge of the external trigger signal. The trigger pulse must be longer than >1H. To avoid jitter, the camera should be synchronized to an external HD. There are some requirements to the phase between the ext. HD and the Ext. trigger. The falling and rising edge off the trigger should be within 8 µsec. before the falling and rising edge of the ext. HD pulse and not later than 2µsec after the falling and rising edge of the HD pulse (see fig. 14.). The EEN pulse indicates the actual exposure time. The resulting video signal will first start to be read out after the input of an external VD signal. The readout delay should not be to long due to visible dark current noise generated in the CCD sensor. The WEN pulse indicates the start of valid video signal. Refer to timing charts for details. A new trigger pulse must not be applied before the video read out has finished.

Mode setting and all other settings can be done via RS 232C control if rear switch SW1-10 is ON. Mode setting and some other settings can be done by switch if rear switch SW1-10 is OFF. For details: refer to “7. Configuring the Camera”.

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

• The trigger pulse width should be >2H to <2000H.

• External sync system should follow the camera scanning system.

• A new trigger must not be applied before WEN is high.

6.4.5. Long Time Exposure

The exposure time is the interval between 2 ext. VD pulses sent to the VD input of the camera. The exposure starts after input of the first ext. VD pulse, and ends after the next input of the ext. VD pulse, which again starts a new exposure. The long time exposure is a continuous process where each external VD pulse will synchronize the camera, stop on exposure, start a new exposure and read out the previous accumulated signal. The exposure can be selected in intervals of complete vertical timing periods (=792H) This long time exposure mode operates in H non-reset mode. In H non-reset mode the external VD signal and the internal HD signal are synchronized. The exposure will start at the first HD pulse after the falling edge of the external trigger signal. See figure 14. for the phase relationship between ext. HD and ext. VD pulses.

Mode setting and all other settings can be done via RS 232C control if rear switch SW1-10 is ON.

This mode can not be set by switch! For details: refer to “7. Configuring the Camera”.

To use this mode: RS Set function: Trigger mode to “Long Time Shutter” TR=4 Polarity and other functions Input: Ext VD on pin 7 on 12 pin con. (Or 1 on 9 pin ). 4.0 Vp-p ±2.0V. Ext. HD in on pin 6 on 12-pin connector. 4.0 Vp-p ±2.0V. (If used).

Important notes on using this mode

• External sync system should follow the camera scanning system.

• External VD and HD phase relation should follow as shown in fig. 10.

• Depending of the temperature, it is not recommended to use integration >2 seconds.

SW301

The SW301 switches (1-3) in “ON” position activates 75Ω termination of ext. HD and ext. VD signals and it activates 75Ω termination of an ext. trigger signal. The factory setting is “OFF” enabling TTL signal termination for all three signals.

Fig. 22. Switch 301 HD, VD and trigger termination

SW302

The SW302 switch has the following functions: The switches (1-2) determines the color temperature, the switch (3) activates Composite sync. on the green video signal and the switch (4) outputs the WEN signal at the DSUB connector. The white balance is dependent on the color temperature of the light. The available settings are shown in the below table.

8. Camera Control Tool for CV-M77

The Camera Control Tool for Windows 98/NT/2000 can be downloaded from www.jai.com. The control tool contents a camera control program and tools for making your own program. For the integrator and experienced user, the Camera Control Tool is much more than a program with a window interface. It also provides an easy and efficient ActiveX interface built for MS Windows 98, ME, NT and 2000. The OCX interface has the ability to connect to the camera using the serial interface of the PC by reading and writing properties for the camera. This integration requires simple programming skills within Visual Basic, Visual C++ or similar languages in a Microsoft Windows environment.

8.1. Control Tool Windows

Fig. 27. Camera Control Tool windows

- 24 -

CV-M77

8.2. Camera Control Tool Interface

The Camera Control Tool Software is based on a main Tool Bar and a number of associated Tool Windows. Each button in the Tool Bar pops up a separate Tool Window when pressed. The layout of the program can be adjusted by arranging the windows the way it is preferred. The program will store this information and recreate this layout, when the program is restarted. All Camera Control Tools have a Communication Window and an About Window. The other window(s) contains camera control commands.

The About window

The about window contains a picture of the camera and information about the version of the program, Internet connection to JAI A/S and access to the help documents. The List box that contains the help documents will list all files, which have the extension .pdf and that are found in the program (default) folder

C:\Program Files\JAI A-S\’Control Tool Name’

It is possible to download updated operation manuals from the jai website:

http://www.jai.com/camera/manuals.asp/sprog=uk

An updated manual can be saved in the folder address mentioned above and it will automatically be included in the list of help files. For newer camera models the About Window also shows Model Name, camera ID and User ID. It is possible to edit and save free text in User ID. At the bottom of the windows (all windows but the Communication Window is a coloured bar. The bar is green when the Camera Control Tool is connected to a camera and the camera is turned on. The bar is red when the Camera Control Tool is not connected to a camera or when the camera is turned off.

The Communication Window

The Communication Window is used to connect the Camera Control Tool with the JAI camera. Depending of camera there are 2 possible ways to communicate with a JAI camera. RS-232: Select the communication port, where the serial cable is connected from the list box in the ‘Communication Port’ field, or click the ‘Auto’ button to search for a camera on communication port 1 to 16. The camera control program automatically sends a camera request on every communication port. The user is prompted to use a communication port if a camera answers the request. RS-232 and Camera Link: The Communication Window looks a bit different when it is possible to communicate with the camera using Camera Link and RS-232 com port. The Communication area contains 2 list boxes now.

- 25 -

CV-M77

RS-232 communication:

1. Select ’COM-ports’ from the ’CL Manufacturer/COM-ports’ list Box.

2. Select the communication port, where the serial cable is connected to the camera from the ’Serial Port’ list box or click the ‘Auto’ button to search for a camera on communication port 1 to 16.

The Serial Port list box and the Auto search button are only active when COM-ports is selected.

Camera Link communication: The ’CL Manufacturer/COM-ports’ list box also contains DLL file names (or frame grabber names) for all Camera Link frame grabbers that are installed in the pc. This is done by using a DLL file called "clserial.dll" to upload all frame grabber DLLs that are found in the pc. Just select the option for the frame grabber that is installed in the pc.

Auto search Click the auto button to search for a camera on communication port 1 to 16. The camera control program automatically sends camera request on every communication port. The user is prompted to use a communication port if a camera answers the request. This button is only used for RS-232 communication.

Off/On-line mode The Camera Control Tool Application can run Offline (without a camera attached) and all functions are fully functional in offline mode. Off line mode is indicated in The Communication Window, where a status field with graphic and text indicates the on/off-line status. Changing the selected communication port (from the communication window) changes the online/off-line status. If a camera is found on the selected communication port the application runs online otherwise offline.

Changing the settings in the application will automatically update the camera settings when the application is online. If the application looses connection with the camera it will automatically go to offline mode and it is indicated in the communication window.

Synchronize program and camera The Camera Control software has the ability to synchronize either the camera or the program. Click Synchronize camera to write all settings from the program to the camera or click the Synchronize program to load all settings from the camera to the program.

Files

When clicking the Write to File or Read from File button, the user is prompted for a file using a standard file dialog. New files are created if they do not already exist. Files for camera settings have the extension cam. Information about the communication port is not stored in the files. All settings are automatically sent to the camera when a file has been loaded (if the camera is online).

- 26 -

CV-M77

Factory and User Settings

Use the Store button to store the current camera settings into the user settings area in EEPROM. Current camera settings are not saved when the camera is turned off. To save current camera settings you have to save them on the available user areas. Use the Load button to restore previously saved camera settings from either the Factory or the User EEPROM area.

Write All Camera Data to File. Click the “Write Camera Data” button to save all camera settings into a text file. The information that can be saved is: Model Name, Camera ID, User ID, Firmware Version, Current Settings, Factory Settings and the available User Areas. The file is formatted as shown in the picture below:

EEPROM Current Area. Click the ‘Get Area’ button to read the power up settings area number.

7.3.3. Using the Camera Control Tool

Here is some practical information about the Camera Control Tool:

1. The Camera Control Tool bar is always on top of other windows.

2. When you minimize the Camera Control Tool bar all open windows will close.

3. It is possible to work with the Camera Control Tool when the camera is online and when the camera is offline.

4. The newer JAI cameras always start up with the last used user area (but for some old models it will start up with the last saved user area.)

5. The Camera Control Tool saves the last used settings (not the user area), which don’t have to be the same as for the last saved user area.

6. The setup file ’CameraName.ini’ stores all information about camera settings. When the program is started the last settings for the program are loaded from the file ’CameraName.ini’

7. When you turn on the camera and the Camera Control Tool, it is possible that the Camera Control Tool does not show the actual camera settings (see 4. and 5.).

a. To obtain the camera settings click “Synchronize Program”. b. To send the settings that are saved in the Camera Control Tool (last used settings)

to the camera click “Synchronize Camera”.

c. To see which area the camera has started up in click “Get Area”.
