Software and Hardware Setup

Host System Requirements

To achieve best system performance, the following minimum requirements are recommended:  Operating system: Windows XP Professional, Windows Vista, Windows 7 (either 32-bit or 64-bit for

all) are supported.

Network Adapter Requirements

 GigE network adapter (either PCI card or LOM): For high performance you must use a Intel

PRO/ 1000 MT ad apter.

The Spyder3 GEV camera works only with network adapters based on the Intel 82546, 82541, and 82540 network chips. The driver will also function with adapters based on the Intel 82544 chip, but these are not recommended due to bugs in the chip that can cause control packets to be lost if sent while data is streaming.

Ethernet Switch Requirements

When you require more than one device on the same network or a camera-to-PC separation of more than 100 metres, you can use an Ethernet switch. Since the Spyder3 GEV camera complies with the Internet Protocol, the camera should work with all standard Ethernet switches. However, switches offer a range of functions and performance grades, so care must be taken to choose the right switch for a particular application.

Setup Steps: Overview

Take the following steps in order to setup and run your camera system. They are described briefly below and in more detail in the following sections.

1. Install and Configure Ethernet Network Card

If your host computer does not have a Gigabit network adapter or equivalent (PCI bus Gigabit NIC) already installed, then you need to install one.

For Gigabit performance we recommend the Intel PRO/ 1000 MT adapter, or equivalent. Follow the manufactu rer’s installation instructions.

A GigE Vision compliant XML device description file is embedded within the cam era’s firmware allowing GigE Vision compliant applications (e.g. Pleora`s Coyote, and SaperaLT) to recognize the cam era’s cap abilities im mediately after connection. The Spyder3 camera was tested with and supports SaperaLT which gives you access to the CamExpert GUI, a GigE Vision compliant application.

Software Installation

Install Sapera LT with CamExpert to control the Spyder3. You can access Sapera drivers, SDKs, and demos from the following link: http:/ / www.teledynedalsa.com/ mv/ support/ driverSDKlist.aspx

Teledyne DALSA 03-032-20123-00

16 Spyder3 GigE Vision SG-14 Cameras User’s Manual

2. Connect Power, Ethernet and I/O Cables

 Connect a power cable from the camera to a +12 VDC to +15 VDC power supply.  Connect the Ethernet cable from the camera to the computer Ethernet jack.  If using the external signals connect the external control cable to the camera.

3. Establish communicating with the camera

Start the GUI and establish communication with the camera.

4. Check camera LED, settings and test pattern

Ensure that the camera is operating properly by checking the LED, the current settings, and by acquiring a test pattern.

5. Operate the Camera

At this point you will be ready to operate the camera in order to acquire and retrieve images, set camera functions, and save settings.

03-032-20123-00 Teledyne DALSA

Spyder3 GigE Vision SG-14 Cameras User’s Manual 17

Step 1. Ethernet Network Card: Install and Configure

Install Network Card

The following network card has been tested and is recommended for use with this camera: Intel Pro/ 1000 MT Desktop Adapter (33-MHz, 32-bit PCI). Order Code: PWLA8391GT (single packs). Follow the manufactu rer’s recom mend ations t o install this card in the host PC.

Configure Network Card

The configuration shown here uses the Windows XP operating system as the host platform.

The camera communicates using the Ethernet connection and employs the static IP address: 192.168.5.100 (default). A static address ensures the fastest operation. Alternatively, you can use a dynamic IP address.

To configure the network card from the host PC:

1. In the Start menu under ―Control Panel‖ select ―Netw ork Connections,‖ and configure the

network card as follows:

2. Select the installed network card and click on ―Ch ange settin gs of this con n ectio n .‖

3. Enable the ―Intern et Prot ocol (TCP/ IP)‖ option only.

4. With ―Internet Pr otocol (TCP/ IP)‖ selected , click on the ―Prop erties‖ bu tton .

GPIO Connector: External Input

A single 15-pin general purpose input / output (GPIO) connector is used to receive or control external signals. For example, the GPIO connector can be used to receive EXSYNC, PRIN (pixel reset), and direction signals.

The GPIO connector is programmed through the GUI application. In CamExpert the relevant parameters are located in the category Inputs Group.

Figure 12: GPIO Connector and Pin Numbers

Table 7: GPIO Connector Pinout

A schematic of the TTL input circuitry is shown in Figure 13: TTL Input Schematic. The input signals are fed into the engine from external sources via the GPIO connector.

GPIO Isolation

All of the GPIOs are isolated from the rest of the camera and the camera case. They are not isolated with respect to each other and share a common return (ground) through pin 5 of the GPIO connector. Note: The shell connection of the GPIO connector is not isolated and it should not be used as a return (ground) for the GPIO signals. The shell connection is attached to the camera case.

GPIO Configuration

Refer to Appendix C: GPIO Control for a detailed description of the GPIO use-cases and configuration options.

Using Sapera CamExpert with Spyder3 Cameras

CamExpert is the camera interfacing tool supported by the Sapera library. When used with a Spyder3 camera, CamExpert allows a user to test all Spyder3 operating modes. Additionally CamExpert saves the Spyder3 user settings configuration to the camera or saves multiple configurations as individual camera parameter files on the host system (*.ccf).

An important component of CamExpert is its live acquisition display window which allows immediate verification of timing or control parameters without the need to run a separate acquisition program.

For context sensitive help, click on the button then click on a camera configuration parameter. A short description of the configuration parameter will be shown in a popup. Click on the button to

open the help file for more descriptive information on CamExpert.

The central section of CamExpert provides access to the Spyder3 parameters. Note: The availability of the parameters is dependent on the CamExpert user setting.

Description of the Camera Settings

The camera operates in one of three settings:

1. Current session

2. User setting

3. Factory setting (Default, read-only)

The current settings can be saved (thereby becoming the user setting) using the User Set Save parameter. A previously saved user setting (User Set 1) or the factory settings can be restored using the User Set Selector and User Set Load parameters.

The relationship between these three settings is illustrated here and described below:

32 Spyder3 GigE Vision SG-14 Cameras User’s Manual

Current Session Active Setting

The active setting for the current session is the set of configurations that are operating while the camera is currently running, including all unsaved changes you have made to the settings before saving them .

These active settings are stored in the camera’s volatile memory and will be lost and cannot be restored if the camera resets or if the camera is powered down or loses power.

To save these settings for reuse the next time you power up or reset the camera, or to protect against losing them in the case of power loss, you must save the current settings using the User Set Save parameter. Once saved, the current settings become your User Set 1.

User Setting

The user setting is the saved set of camera configurations that you can customize, resave, and restore. By default the user settings are shipped with the same settings as the factory set.

The command User Set Save saves the current settings to non-volatile memory as a User Set. The camera automatically restores the last saved user settings when it resets and / or powers up.

To restore the last saved user settings, select the User Set parameter you want to restore and then select the User Set Load parameter.

Factory (Default) Settings

The default setting is the camera settings that were shipped with the camera and which loaded during the

cam era’s first pow er -up. To load or restore the original factory settings, at any time, select the Default / Factory Setting parameter and then select the User Set Load parameter.

Note: By default, the user settings are set to the factory settings.

Please note: the following features are not restored during a factory setting load / restore:

 FFC Coefficients set number  Analog Gain selector  Blacklevel selector  Digital Offset selector  Background Subtract selector  Line selector  PRNU CalibrationTarget  Gain Calibration Target  Gain Calibration Selector

Line Trigger

Trigger Mode

The state of the line trigger. If OFF, then the line trigger is internally generated. If ON, then triggered by an external signal.

Trigger Source

The external source that causes a line trigger. The line trigger is from the GPIO_PIN0. This feature is available only when Line Trigger Mode is set to ON.

Trigger Activation

Determines the type of signal (high or low) that will cause a line trigger. Line Trigger Mode must be ON.

External Line Trigger Frequency

Reads the external line trigger frequency. NOTE: The camera cannot detect frequency less than 5 Hz and will display 1 if it cannot detect a signal. This featur e is available when the Line Trigger Mode is set o ON and Sensor Direction Control is set to External.

Timing: Exposure and Synchronization

Image exposures are initiated by an event. The trigger event is either the camera's programmable internal clock used in free running mode, an external input used for synchronizing exposures to external triggers, or a programmed function call message by the controlling computer.

Trigger commands are available as members of the Sensor Control set.

GigE Vision Input Controls

The three trigger modes are described here:

Free running (trigger disabled)

The camera free-running mode has a programmable internal timer for line rate and a programmable exposure period. Line rate is 0.1 fps to the maximum supported by the sensor. Exposures range from the sensor minimum to a maximum also dependent on the current line rate. This always uses Synchronous mode where exposure is aligned to the sensor horizontal line timing.

External trigger

Exposures are controlled by an external trigger signal. External signals are isolated by an opto-coupler input with a time programmable debounce circuit. The following section provides information on external trigger timing.

Software trigger

An exposure trigger is sent as a control command via the network connection. Software triggers can not be considered time accurate due to network latency and sequential command jitter. But a software trigger is more responsive than calling a single-line acquisition (Snap command) since the latter must validate the acquisition parameters and modify on-board buffer allocation if the buffer size has changed since the last acquisition.

Exposure Modes in Detail

Mode A. Internally Programmable Line Rate and Exposure Time (Factory Setting): ExposureMode Timed and LineTriggerMode Off (Internal)

Operates at a maximum line rate and exposure time.

 When setting the line rate (using the AcquisitionLineRateAbs command), exposure time will be reduced, if

necessary, to accommodate the new line rate. The exposure time will always be set to the maximum time (line period – line transfer time – pixel reset time) for that line rate when a new line rate requiring reduced exposure time is entered.

 When setting the exposure time (using the ExposureTimeAbs command), line time will be increased, if

necessary, to accommodate the exposure time. Under this condition, the line time will equal the exposure time + line transfer time.

Example 1: Exposure Time less than Line Period

Mode B. External Trigger with Maximum Exposure: ExposureMode Off and LineTriggerMode On (External)

Line rate is set by the period of the external trigger pulses. The falling edge of the external trigger marks the beginning of the exposure.

Example 2: Line Rate is set by External Trigger Pulses.

Mode C. Smart EXSYNC, External Line Rate and Exposure Time: ExposureMode TriggerWidth and LineTriggerMode On (External)

In this mode, EXSYNC sets both the line period and the exposure time. The rising edge of EXSYNC marks the beginning of the exposure and the falling edge initiates readout.

Example 3: Trigger Period is Repetitive and Greater than Read Out Time.

Binning

Binning is the combining of two or more image sensor pixels to form a new combined pixel prior to readout or digitizing. A binned image using the same exposure settings as a non -binned image will show an improved signal-to-noise ratio, reduced scanning times (due to lower spatial resolution) and save as a smaller image file size compared with a non-binned image, at the expense of lower image resolution.

For this camera, the default binning value is 2 x 2, 4 physical pixels on the sensor are combined into one image pixel. This operating mode is ideal for applications that require faster acquisition and processing times and require greater signal collection.

The Binning Horizontal feature in the Image Format Control set represents the number of horizontal pixels that will be combined (added) together.

Processing Chain Overview and Description

The followin g d iagram sh ow s a sim p lified block d iagr am of the camer a’s analog an d d ig ital processing

chain.

The analog processing chain begins with an analog gain adjustment, followed by an analog offset adjustment. These adjustments are applied to the video analog signal prior to its digitization by an A/ D converter.

The digital processing chain contains the FPN correction, the PRNU correction, the background subtract, and the digital gain and offset.

All of these elements are user programmable and most are members of the Analog Controls and Data Processing sets.

Figure 24: Signal Processing Chain

Teledyne DALSA 03-032-20123-00

46 Spyder3 GigE Vision SG-14 Cameras User’s Manual

Analog Processing

Optimizing offset performance and gain in the analog domain lets you achieve a better signal-to-noise ratio and dynamic range than you would achieve by trying to optimize the offset in the digital domain only. Therefore, you should perform all analog adjustments prior to any digital adjustments.

1. Analog gain (the Gain (dB) or Calibrate Gain Target parameters in the Analog Controls set) is

multiplied by the analog signal to increase the signal strength before the A/ D conversion. It is used to take advantage of the full dynamic range of the A/ D converter. For example, in a low light situation the brightest part of the image may be consistently coming in at only 50% of the DN. An analog gain of 6 dB (2x) will ensure full use of the dynamic range of the A/ D converter. Of course the noise is also increased.

2. The analog offset or black level (Black Level (DN) command) is an ―artificial‖ offset introd u ced into

the video path to ensure that the A/ D is functioning properly. The analog offset should be set so that it is at least 3 times the rms noise value at the current gain.

Digital Processing

To optimize camera performance, digital signal processing should be completed after any analog adjustments.

1. Fixed pattern noise (FPN) calibration (calculated using the Calibrate FPN parameter) is used to

subtract away individual pixel dark current.

2. The digital offset (Digital Offset (DN) parameter) en ables th e su b traction of the ―artificial‖ A / D

offset (the analog offset) so that application of the PRNU coefficient does not result in artifacts at low light levels due to the offset value. You may want to set the Digital Offset (DN) value if you are not using FPN correction but want to perform PRNU correction.

3. Photo-Response Non-Uniformity (PRNU) coefficients (calculated using the PRNU Target and

Calibrate PRNU, or PRNU Calibration Algorithm Selector parameters in the Data Processing family) are used to correct the difference in responsivity of individual pixels (i.e. given the same amount of light different pixels will charge up at different rates) and the change in light intensity across the image either because of the light source or due to optical aberrations (e.g. there may be more light in the center of the image). PRNU coefficients are multipliers and are defined to be of a value greater than or equal to 1. This ensures that all pixels will saturate together.

4. Background subtract (Background Subtract (DN) parameter) and system (digital) gain (Digital

Gain (DN) parameter) are used to increase image contrast after FPN and PRNU calibration. It is useful for systems that process 8-b it d ata bu t w an t to take ad v antage of the cam era’s 12 bit d igital processing chain. For example, if you find that your image is consistently between 128 and 255DN (8 bit), you can subtract off 128 (Background Subtract (DN) 2048) and then multiply by 2 (Digital Gain (DN) 8192) to get an output range from 0 to 255.

Analog Gain and Offset Adjustment

Optimizing offset performance and gain in the analog domain allows you to achieve a better signal-tonoise ratio (dynamic range). All analog signal processing chain commands should be performed prior to FPN and PRNU calibration and prior to digital signal processing commands.

Set Analog Gain

Analog gain is multiplied by the analog signal to increase the signal strength before the A/ D conversion. It is used to take advantage of the full dynamic range of the A/ D converter .

The Analog Controls > Gain Selector feature selects the tap to apply the gain value to. The Gain (dB) feature is then used to apply a gain value in a range from -10 dB to +10 dB.

Note: This feature is not available on the 4k camera model.

Calibrate Camera Gain

Instead of manually setting the analog gain to a specific value, the camera can determine appropriate gain values. This command calculates and sets the analog gain according to the algorithm determined by the first parameter using the Calibrate Gain Selector feature. This feature is not available for the SG-1404K80 cameras.

Notes:

 This function requires constant light input while executing.  If very few tap pixels are w ithin the ROI, gain calculation may not be optimal.  When all taps are selected, taps outside of the ROI are set to the average gain of the taps that are

within the ROI.

 Perform analog gain algorithms before performing FPN and PRNU calibration.  All digital settings affect the analog gain calibration. If you do not want the digital processing to have

any effect on the camera gain calibration, then turn off all digital settings by sending the commands: DigitalOffsetRaw 0, EnablePixelCoefficients 0, SubtractBackgroundRaw 0, and DigitalGainRaw 4096

Please note: only the ―Digital A ver age Pixel at Target‖ algorithm is available on 4k models.

Also note: the Calibrate Gain Selector command can take up to 10 seconds. Please adjust the GUI's timeout values (in the Advanced Processing set) accordingly.

Set Analog Offset (Black Level)

Sets the analog offset. The analog offset should be set so that it is at least 3 times the rms noise value at the current gain. The analog offset is configured for the noise at the maximum specified gain and as a result you should not need to ad just the analog offset.

The Black Level Selector parameter selects which tap is selected: All, Tap1, or Tap2. Followed by using the Black Level (DN) feature to select an offset value in a range from 0 to 255 DN (12 bit LSB).

Update Analog Gain Reference

The Update Gain Reference feature sets the current analog gain setting to be the 0 dB point. This is useful after tap gain matching allowing you to change the gain on all taps by the same amount.

Calibrate the Camera to Remove Non-Uniformity (Flat Field Correction)

Calibration Overview

When a camera images a uniformly lit field, ideally, all of the pixels will have the same gray value. However, in practice, this is rarely the case (see example below) as a number of factors can contribute to gray scale non-uniformity in an image: Lighting non-uniformities and lens distortion, PRNU (pixel response non-uniformity) in the imager, FPN (fixed pattern noise) in the imager, etc.

Figure 25. Image with non-uniformities

By calibrating the camera you can eliminate the small gain difference between pixels and compensate for light distortion. This calibration employs a two-point correction that is applied to the raw value of each pixel so that non-uniformities are flattened out. The response of each pixel will appear to be virtually identical to that of all the other pixels of the sensor for an equal amount of exposure.

Correction Overview

This camera has the ability to calculate correction coefficients in order to remove non-uniformity in the image. This video correction operates on a pixel-by-pixel basis and implements a two point correction for each pixel. This correction can reduce or eliminate image distortion caused by the following factors:

 Fixed Pattern Noise (FPN)  Photo Response Non Uniformity (PRNU)  Lens and light source non-uniformity

Correction is implemented such that for each pixel:

=[(V

output

The algorithm is performed in two steps. The fixed offset (FPN) is determined first by performing a calibration without any light. This calibration determines exactly how much offset to subtract per pixel in order to obtain flat output when the CCD is not exposed.

The white light calibration is performed next to determine the multiplication factors required to bring each pixel to the required value (target) for flat, white output. Video output is set slightly above the brightest pixel (depending on offset subtracted).

– FPN (pixel ) - digital offset) * PRNU (pixel) – Background Subtract] x System Gain

input

Flat Field Correction Restrictions

It is important to do the FPN correction first. Results of the FPN correction are used in the PRNU procedure. We recommend that you repeat the correction when a temperature change greater than 10°C occurs or if you change the analog gain, integration time, or line rate.

PRNU correction requires a clean, white reference. The quality of this reference is important for proper calibration. White paper is often not sufficient because the grain in the white paper will distort the correction. White plastic or white ceramic will lead to better balancing.

Note: If your illumination or white reference does not extend the full field of view of the camera, the camera will send a warning.

For best results, ensure that:  50 or 60 Hz ambient light flicker is sufficiently low not to affect camera performance and calibration

results.

 For best results, the analog gain should be adjusted for the expected operating conditions and the

ratio of the brightest to darkest pixel in a tap should be less than 3 to 1 where:

 The camera is capable of operating under a range of 8 to 1, but will clip values larger than this ratio.

03-032-20123-00 Teledyne DALSA

Spyder3 GigE Vision SG-14 Cameras User’s Manual 51

 The brightest pixel should be slightly below the target output.  When 6.25% of pixels from a single row within the region of interest are clipped, flat field correction

results may be inaccurate.

 Correction results are valid only for the current analog gain and offset values. If you change these

values, it is recommended that you recalculate your coefficients.

Digital Signal Processing

To optimize camera performance, digital signal processing should be completed after any analog adjustments.

Step 1: Prepare for Calibration

For best results, the camera should be setup for calibration with similar conditions as to those in which it will be used. For example, data mode, exposure times and line rates, scan direction, etc.

Step 2: FPN Calibration

Note that you do not need to turn off the FPN and PRNU coefficients before calibrating, the camera will do this automatically.

1. Stop all light from entering the camera. The best way to do this is to put on lens cap.

2. Calibrate FPN using the FPN Calibrate command.

3. Use the Read FFC Calibration Result parameter to determine if your calibration was a success or

not.

4. To save the calibrated FPN coefficients to the FFC coefficient set shown, use the Set FPN Save

parameter.

Step 3: PRNU Calibration: White Calibration

Performs PRNU calibration to user entered value and eliminates the difference in responsivity between the most and least sensitive pixel creating a uniform response to light. Using this command, you must provide a calibration target.

Executing these algorithms causes the Background Subtract Raw value to be set to 0 (no background subtraction) and the Digital Gain Raw value to 4096 (unity digital gain). The pixel coefficients are disabled (Pixel Set Load 0) during the algorithm execution but returned to the state they were prior to command execution.

1. Remove the lens cap and prepare a white, uniform target.

2. Adjust the line rate so that the average output is about 80% of the full ou tput by: adjusting the

lighting, if you are using an internal exposure mode. Or, adjust the line rate, if you are using the Smart Exsync mode.

3. Set the PRNU target value using the Target to Calibrate PRNU command. The target value (always

counted as 12-bit) and is 1024 to 4055 DN. For example, if you want to set the target to 255 x 80% = 204 DN in 8-bit mode, then the target value is (204/ 255) x 4096 = 3277 DN in 8-bit mode. Therefore, you can set the target to 3300 DN: Target to Calibrate PRNU is 3300.

4. Calibrate the PRNU using the PRNU Calibrate command.

5. Use the Read FFC Calibration Result parameter to determine if your calibration was a success or

not—see the belowfor the possible results.

6. To save the calibrated PRNU coefficients to the FCC coefficient set shown, use the Set PRNU Save

parameter.

7. After the above command is completed, both the FPN and PRNU coefficients are automatically

turned on.

Appendix A: Clear Dark Current

Setting the Readout Mode

Refer to the Clearing Dark Current section for more information on this feature.

Use the Readout Mode feature (from the Analog Controls family) to clear out dark current charge in the vertical transfer gates immediately before the sensor is read out.

The available readout modes are Auto, Dark Current, and Immediate Readout.

Auto: Clears dark current below ~ 45% of the maximum line rate. (Default mode.) Dark Current Clear: Dark current clear. Always clears dark. Reduces the maximum line rate. Immediate Readout: Immediate readout. Does not clear dark current.

Notes:  The vertical transfer gates collect dark current during the line period. This collected current is added

to the pixel charge. This additional charge is especially noticeable at slower line rates.

 This value is saved with the camera settings.  If the user is using internally programmable line rate and exposure time, or internally programmable

line rate and maximum exposure time, and immediate read out mode, with Acquisition LineRate Abs at 45% of the maximum, and then Read outMode 1 is selected, the following warning will be displayed, but the AcquisitionLineRateAbs value will not be changed: Warning 09: Internal line rate inconsistent with readout time> The effect in both internal and external line rate modes is that an EXSYNC is skipped and, therefore, the output will be at least twice as bright.

Gate Dark Current Clear

Image sensors accumulate dark current while they wait for a trigger signal. If the readout is not triggered in a reasonable amount of time, then this dark current accumulation may increase to an excessive amount. The result of this happening will be that the first row, and possibly additional rows (lines), of the image will be corrupt.

The sensor used in the Spyder3 GEV camera contains two sources of dark current that will accumulate with time: 1) in the photo sensitive area, an d 2) in the gates used to clock-out the charge. The gate dark current can account for approximately 20% of the total dark current present. While the exposure control has direct control over the amount of dark current in the photo sensitive area, it has no control over the charge accumulated in the gates. Even with exposure control on, at low line rates, this gate charge can cause the camera to saturate.

Using the Readout Mode command, the camera user can control the camera's behavior in order to minimize the dark current artifact.

The modes of operation selected by the Readout Mode command are: Auto, On, or Off.

Note: This command is only available in low sensitivity and tall pixel modes. High sensitivity mode operates only in the immediate read out position.

Immediate read out mode (Off)

In this mode the image is read out, including accumulated dark current, immediately following the trigger or the EXSYNC falling edge. There are no line rate limitations other than the amount of gate d ark current that can be tolerated at low line rates. There are no timing or exposure anomalies other than situations where EXSYNC is removed from camera. In this case, the camera will operate in a "watchdog" state. For information on artifacts that may be experienced while using this mode, see the Artifacts section below.

Gate dark current clear mode (On)

In this mode the gate dark current will be cleared continuously. After the trigger (EXSYNC) is received, the dark current is cleared from the image sensor before the image is acquired. The line rate is limited to ½ the maximum line rate available for that model of camera. For information on artifacts that may be experienced while using this mode, see the Artifacts section below.

When operating in the dark current clear mode, there will be a slight delay, equivalent to one read out time, before the actual exposure is implemented. The actual exposure time will not be altered.

Table 14.

Auto Mode (Auto)

In this mode the line rate from the camera will automatically cause a switch between the gate dark current clear mode and non gate dark current clear mode. The frequency of when this mode switchover occurs depends on the camera model. In cases where the line rate is rapidly increased from below the Dark Current Clear to Immediate Readout Transition Frequency to above the Immediate Readout to Dark Current Clear Transition Frequency, the first line following this transition will likely be corrupted. The table below outlines the artifacts that may be seen d uring this transition period. All subsequent lines after this occurrence will be as expected. In the case of a slow transition (that is, when the EXSYNC line rate increases by less than 10% of the previous line rate) a line readout will not become corrupt. There are also limitations on the exposure time when operating in auto mode: If the line rate exceeds half the maximum line rate, then the exposure time cannot exceed the time stated in Table 14. Note: DALSA recommends Auto mode for most users. For information on artifacts that may be experienced while using this mode, see the Artifacts section below.

Appendix B: Sensitivity Mode

Sensitivity Mode and Pixel Readout

The camera has the option to operate in either high sensitivity or low sensitivity mode or in tall pixel mode.

When in high sensitivity mode, the camera uses both line scan sensors and its responsivity increases accordingly. When in low sensitivity mode, the camera uses the bottom se nsor. When operating in tall pixel mode, the camera operates using both sensors, creating a 28µm x 14µm pixel.

High sensitivity mode permits much greater scanning speeds in low light. It can also allow for reduced lighting levels.

The sensitivity mode is software controlled through GigE-compliant interface using the Sensitivity Mode feature, part of the Image Format Controls set.

In high sensitivity mode, the camera uses either a 14µm x 14µm pixel (1k and 2k models) or a 10µm x 10µm pixel (4k model) and captures the same image twice, resulting in a brighter image.

Description

INPUT_ 0+

LVDS/ TTL format (positive)

Appendix C: GPIO Control

The cam era’s Gener al Purp ose Inpu t / Outp ut (GPIO) con n ector allow s the ca m era to receive (and in

some cases output) direct, real-time control signals that are independent from the Ethernet communications. For example, the GPIO connector can be used to control EXSYNC, PRIN (pixel reset), and direction signals.

You may want to use non-Ethernet control signals because Ethernet network protocols introduce a small but measurable and unpredictable lag that may not allow for extremely precise and reliable control of camera behavior, such as line rate, integration time, and readout direction.

In general, to configure the GPIO you need to accomplish three main tasks:

1. Assign a physical camera pin and signal to a GPIO Input number.

2. Map the GPIO Input or Output using the parameter commands located in the Line Trigger

Function, Inputs, Outputs, Direction Control, and Sensor Control groups in the GUI. (Please note that this step has already been performed for the Beginner level scenarios described below.)

3. If you want to use applications other than those provided in the Beginner level examples, you can

use the LUT programming language to map the GPIO Input Configuration to the GPIO Output Configuration in the Guru level.

Note: the screenshots presented in this section are from the CamExpert GUI. If you are using a different GUI the arrangement of the commands and parameters may be different.

GPIO Getting Started: Beginner Mode

NOTE: The following instructions are based on the default settings of the camera. Cameras are shipped from the factory in a default setting. Default settings are restored by loading the factory default (see Trigger Settings (GURU) for details).

The GPIO Connector

The GPIO connector is used to interface external signals in and out of the camera. The connector contains 15 pins that can configure 4 inputs and 4 outputs (See Figure 1 and Table 1). Three of the four inputs/ outputs (i.e. 0 to 2) can be configured as Off, LVDS (Low Voltage Differential Signal), or TTL (Transistor/ Transistor Logic). The remaining input and output (i.e. 3), can be configured as either Off or TTL.

Configure GPIO Signal Levels

Before using any external triggers, the input lines must be set to a proper signal level: either TTL (transistor-transistor logic) or LVDS (low-voltage differential signaling). The Spyder 3 GigE cameras hardwire 3 input lines that require signal level selection:

Line0 – line trigger or rotary encoder phase A input Line1 - Frame trigger Line2 – Direction control or rotary encoder phase B input

Steps 1

Select the line: 0, 1, 2.

Steps 2

Select the corresponding signal format: TTL or LVDS.

Trigger Settings: GURU Mode

In most use-cases the camera mode settings described in the Beginner section will suffice. Using the commands and parameters available in the Guru level allow you to perform finer adjustments to the triggers or create different use-cases from the ones predefined in the Beginner level.

The following instructions are based on the default settings of the camera. Cameras are shipped from the factory in a default setting. Default settings are restored by loading the factory default (see the figure below).

NOTE: loading the factory default will take 10 seconds or more to complete. If you are not using CamExpert, it is recommended that you set your GUI timeout values to maximum setting. If you do not adjust the GUI timeout, your GUI will disconnect during factory load.

After Factory default settings are loaded, parameters will be configured as follows;

Pulse Generator

The behavior of the Pulse Generator is defined by their delay and w idth. The delay is the amount of time the pulse is inactive prior to the pulse, and the width is the amount of time the pulse is active. The Pulse Generator signals can be set in either triggered or periodic mode. In triggered mode, the pulse generator is triggered by either the rising edge or high level of the input signal. When triggered, the pulse generator is inactive for the duration of the delay, then active for the duration of the width. After that, it will become inactive until the next trigger occurs. If a trigger occurs while pulse generator is already handling a previous trigger, the new trigger is ignored. In periodic mode, the trigger continuously generates a signal that is based on the co nfigured delay and width. The period of the pulse is therefore the delay time plus the width time.

Displays the value of the parameter, in nanoseconds, of a complete delay-width cycle of the pulse generator. This value is computed every time the delay, width or granularity is modified and is available regardless of the periodic mode.

Pulse Frequency (Hz)

Displays the frequency of the pulse generator. This value is computed every time the delay, width or granularity is modified and is available regardless of the periodic mode.

Pulse Generator Timing

Positive Pulse Generated from a Rising Edge Trigger

Negative Pulse Generated from a Level High Trigger

The software can generate two internal signals using the internal pulse generators. The behavior of each of these two pulse generators is defined by a delay and a width. As shown in the accompanying diagrams, the delay is the time between the trigger and the pulse transitions. The width is the time the pulse stays at the active level before transitioning. The periodic mode, the delay determines the low time of the pulse. Each pulse generator generates a signal that can be used as an input to the GPIO Control Block. A triggered pulse generator needs an input signal that comes from an output of the GPIO Control Block.

Note: There is one clock cycle between the output signal of a pulse generator and the outputs of the GPIO

Control Block. The labels for the inputs from the pulse generators in the GPIO Control Block programming languages are:

Rescaler

The Rescaler lets you change the frequency of a periodic input signal. You can use the Rescaler to multiply the period by up to 4096 or divide it by up to 4095.

Figure 61: Granularity

The Rescaler is defined by the following settings:

Granularity

The granularity is the number of clock cycles during which the rescaler checks for activity on its input. The value to use depends on the period/ frequency of the input signal. If a frequency lies between two different granularity settings, the lowest setting will yield a better precision. The possible values are:

 The ―Min. Frequency‖ is a fixed min im um , otherw ise the incom ing signal per iod cou n ter gets

The divider applied to the input frequency. The resulting frequency is computed as follows:

Input Selection

Indicates which label in the GPIO LUT will be associated with the rescaler. Make sure you select an input label that is not being used for its default behavior. For example, Q9 is used to send a trigger to pulse generator 0. If pulse generator 0 is used in triggered mode, then it will be triggered by Q9 and cannot be used as the input for the rescaler. The possible values are: Q3, Q7, Q8. Q9, Q10, Q11, Q16, and Q17.

Backup Enabled

Indicates if the rescaler will use a back-up input source if its main source stops its activity.

Backup Window

Specifies the window of time during which there can be no activity from the main input source before the rescaler switches to the back-up source. As soon as activity is detected, the rescaler returns to its main input source.

Input Debouncing

The Debouncers tab is used to configure the debouncers of the camera. The debouncers are associated with the first and second PHYSICAL inputs of the software, usually Input 1 and Input 2.

The debouncers make sure that their corresponding inputs filter out bouncing effects. Bouncing is when there are a few very short pulses when the input signal transitions from low to high. Without debouncing, the controller may see these small pulses as real signals. The debouncers make sure that the signal is truly high for the specified amount of time before it is declared as high. The same applies to the falling edge.

Input 0 Value

Indicates the debouncing value for input 0. Each unit is equal to 16 clock cycles (30ns each), or 480ns.

Input 1 Value

Indicates the debouncing value for input 1. Each unit is equal to 16 clock cycles (30ns each), or 480ns.

Delayer

The delayer is used to delay an input signal. The output of the delayer is the delayed version of the input signal. A delayer is defined by:

Delay: The delay is a value expressed in the number of rising edges from the reference signal. Reference Signal: A periodic input signal that is used to generate the delay from the input source. It is

important that this reference signal be periodic. Also note that the pulse width of the signal you want to delay must be greater than the period of the reference signal. Input Source Selection: The delayer does not have a pre-assigned label in the GPIO Look-Up Table (Qn). This parameter is used to select a label that is not used by another GPIO module. The output of the delayer is considered an input for the GPIO Look -Up Table. The labels for the output from the delayer in the GPIO Control Block programming languages depend on the LUT input configuration.

Figure 62: Delayer

The following sections provide details on the LUT control block, the LUT programming language and the advanced features of the GPIO.

PLC Control

PLC control allows very precise control of the camera. Most users do not need to access the PLC functions as the Beginner level and Guru level functions are adequate for the majority of use-cases. However, Spyder provides a PLC and LUT programming for users who require highly specialized control of the camera functions.

In general, to configure the PLC, you need to accomplish three main tasks:

 Assign a physical camera pin and signal to a GPIO Input number.  Map the GPIO Input or Output using the parameters located in the Line Trigger Function, Inputs, Outputs, Direction

Control, and Sensor Control groups. (NOTE: This will override the factory default in beginner level. )

 Use the LUT programming language to map the GPIO Input Configuration to the GPIO Output in Guru level.

The following sections provide d etails on the LUT control block, the LUT programming language and the advanced features of the PLC.

Note: the screenshots in th is section are fr om the Cam Exp ert GUI. Other GUI’s shou ld contain a simila r

arrangement to what is shown.

The PLC Control Block

All signals pass through the PLC Control Block. Depending on its programming, the PLC Control Block generates output signals that can be redirected to various camera outputs. The PLC control block uses a look up table (LUT) to generate the outputs. This LUT contains eight different inputs, each of which can generate 18 different outputs, resulting in 256 entries of 18 bits.

Teledyne DALSA 03-032-20123-00

90 Spyder3 GigE Vision SG-14 Cameras User’s Manual

Note that all external inputs (from the camera, TTL inputs, and PLC controls) a re resynchronized. The outputs from the look-up table are synchronous. The LUT is programmed using a simple language. This language allows you to create logical equations that specify the conditions that set particular outputs

Note: There is a delay of two clock cycles between the inputs of the LUT and its outputs. A clock cycle has a period of 30 nanoseconds, so the delay is 60 nanoseconds. The signals in the PLC Control Block are defined in the tables below. Inputs to CamExpert are labeled In (where n is an integer from 0 to 7) and outputs are labeled Qn (where n is an integer from 0 to 15).

PLC Input Signal Routing Block

The followin g code sets the first entr y in the PLC’s sign al r outing block: Setting the Signal Routing Block is complicated by the fact that each entry in the table has a different set of enumerated inputs. So for example, a value of 0 for i0(i.e. GPIO Input 0) means something different for i6 (i.e. Pulse Generator 1 Output). Below is a table of enumerated values with respect to each entry.

Signal Routing Block

In its simplest terms, the Signal Routing Block is a group of switches that let you route signals to the Lookup Table. You can direct PLC inputs and feedback inputs to signals I0 through I7.

The Signal Routing Block lets you redirect signals from the IO Block, the Vid eo IO Block, Lookup Table, and the Enhanced Function Block back into the Lookup Table for further processing. Because most of the other blocks in the PLC use preconfigured inputs and outputs, the Signal Routing Block is the primary method of routing a signal from one block to another.

Teledyne DALSA 03-032-20123-00

94 Spyder3 GigE Vision SG-14 Cameras User’s Manual

How the Signal Routing Block Works

The Signal Routing Block has 8 outputs (I0 - I7). Each output uses a 16:1 multiplexer that connects to 16 inputs.

The Signal Routing Block has more than 16 input signals, so not every input can be connected to every one of signals I0 - I7. However, signals I0 - I7 are functionally identical, so connecting to a specific one isn’t important. If you can’t route the input with your first choice, simply choose another.

The Lookup Table lets you connect any input signal I0-I7 to any Lookup Table output signal Q0-Q17

You can manipulate your inputs using simple or complex Boolean expressions. The following expressions are both valid:

Q0 = I6

Q6 = !(I4 & I6) & ((I2 ^ I5) | I1)

How the Lookup Table Works

The Lookup Table has 8 inputs (I0 - I7) capable of two states each (true, false). Thus, the outputs have a total number of 256 input combinations. The result of each combination can be 1 or 0.

When you modify the equations in the Lookup Table, the controller calculates the results of all 256 input combinations and stores the result of each output as a 256-bit lookup table (hence the name). There are 18 outputs (Q0 - Q17), so the controller calculates 18 different lookup tables.

The controller then passes the resulting 18 lookup tables to the IP Engine. Knowing the value of the 8 inputs, the PLC needs only look up the value of the resulting output (for each output), rather than calculate it. Thus, the Lookup Table can achieve a propagation delay of only one system clock cycle (30 ns), regardless of the complexity or number of Boolean expressions.
