PC2-CamLink–Installation Overview Warning! (Grounding Instructions) Static electricity can damage electronic components. Please discharge any static electrical charge by touching a grounded surface, such as the metal computer chassis, before performing any hardware installation. If you do not feel comfortable performing the installation, consult a qualified computer technician. Never remove or install any hardware component with the computer power on.
Sapera LT Library Installation Note: to install Sapera LT and the PC2-CamLink device driver, logon to the workstation as an administrator or with an account that has administrator privileges. The Sapera LT Development Library (or ‘runtime library’ if application execution without development is preferred) must be installed before the PC2-CamLink device driver. • Insert the DALSA Sapera CD-ROM. If AUTORUN is enabled on your computer, the DALSA installation menu is presented.
• When using Windows Vista or Windows 7, a message asking to install the DALSA device software is displayed. Click Install. Upgrading Sapera or any Board Driver When installing a new version of Sapera or a DALSA acquisition board driver in a computer with a previous installation, the current version must be un-installed first. Upgrade scenarios are described below.
To upgrade the board driver only: • Logon the computer as an administrator or with an account that has administrator privileges. • From the Windows start menu select Start • Control Panel • Add or Remove Programs. • Select the DALSA PC2-CamLink Device Driver, click Remove, and then in the InstallShield dialog click on Remove to uninstall the board driver. • When the driver un-install is complete, reboot the computer is prompted to do so. • Logon the computer as an administrator again.
• The PC2-CamLink serial port (mapped to COM3 in this example) is available as a serial port to any serial port application for camera control. Note that this serial port is not listed in the Windows•Control Panel•System Properties•Device Manager because it is a logical serial port mapping.
Configuring Sapera The Sapera Configuration program (Start•Programs•DALSA•Sapera LT•Sapera Configuration) allows the user to see all available Sapera servers for the installed Sapera-compatible boards. Viewing Installed Sapera Servers The System entry represents the system server. It corresponds to the host machine (your computer) and is the only server that should be present at all times. As shown in the following screen shoot, server index 1 is the PC2-CamLink board installed.
Increasing Contiguous Memory for Sapera Resources The Contiguous Memory section lets the user specify the total amount of contiguous memory (a block of physical memory occupying consecutive addresses) reserved for the resources needed for Sapera buffer allocation and Sapera messaging. For both items, the Requested value dialog box shows the default driver memory setting while the Allocated value displays the amount of contiguous memory that has been allocated successfully.
Host Computer Frame Buffer Memory Limitations When planning a Sapera application and the host frame buffers used, as well as other Sapera memory resources, do not forget the needs of the Windows operating system memory. Window XP, as an example, should always have a minimum of 128MB for its own use. A Sapera application using scatter-gather buffers could consume most of the remaining system memory.
IFC Software Installation IFC-SDK™ The IFC (Imaging Foundation Classes) library offers a C++ Application Program Interface (API) intended for use with DALSA’s PC2-CamLink board. IFC is packaged within the “Imaging Studio CD-ROM”. See the IFC-SDK™ Software Manual for information concerning IFC. Information in this manual matches IFC 5.8. Note that PC2-CamLink is supplied with either Imaging Studio (IFC) or Sapera LT.
• The ‘Select Components’ window is displayed (see above screen shot). If you do not see PC2CamLink in the list, select Next to display more boards. Check PC2-CamLink and select Next. Note that only the support, configuration files and examples for the board(s) chosen get copied to your hard drive. • The ‘Select Program Folder’ window is displayed. You can either retain the default program folder or create a new one. Select Next for the installation to begin.
Configuring Serial Port Under IFC Optional COM Port Assignment The IFC “Set Board COM Port” application tool is used to assign the COM Port. Run the program from the Windows Start menu: Start•ProgramsIFC version 5.8•Tools•Set Board Com Port. The ‘Set Image Capture Board Uart ComX Port’ window appears. The PC2-CamLink board/s appear/s in the ‘Select Board’ window. See screenshot below.
• Under ‘Select Board’ choose the PC2-CamLink board (CL2 prefix) you want to map (CL20 is the first PC2-CamLink board, CL21 is the second, …). • Under ‘Select COM Port Number’ assign an unused COM Port number to that PC2-CamLink board and click Set. • Click Close. • Reboot PC for the new settings to take effect. Setup Example Using HyperTerminal • Run HyperTerminal and type a name for the new connection when prompted, click OK.
Starting Camera Configurator The IFC Camera Configurator® program is the camera interfacing tool for frame grabber boards supported by the IFC library, such as the PC2-CamLink. Camera Configurator® generates the required camera configuration file (yourconfig.txt) based on the timing and control parameters entered. Run the program from the Windows Start menu: Start•ProgramsIFC version 5.8•IFC Camera Configurator. The live acquisition window is an important tool within Camera Configurator.
Upgrading Onboard Firmware The Firmware Update program is used to upgrade onboard firmware, automatically opening on the first reboot after installation. It can be launched manually if upgrading a board not present in the system when the PC2-CamLink driver software was first installed.

Camera Control and Synchronization FVAL, LVAL, and DVAL LVAL is the line valid input. The rising edge of LVAL enables and clocks the horizontal offset and clocks the horizontal active counters in the valid video window generator. This indicates a valid line is output by the camera. FVAL is the frame valid input. The rising edge of FVAL enables and clocks the vertical offset and vertical active counters in the valid video window generator. This indicates a valid frame is output by the camera.
CC1-CC4 Four camera controls are reserved to act as general-purpose camera controls. They are referred to in the Camera Link™ standard as CC1, CC2, CC3 and CC4.
Note: The EXSYNC and PRIN pulse generators are fired by the selected trigger source. For area scan, if no trigger source is enabled, the pulse generators are triggered as soon as the previous frame has been captured. This is similar to a free-running mode where EXSYNC and PRIN are generated as fast as possible. For linescan cameras, a line trigger source is required to get an EXSYNC or PRIN pulse. You can select the user timer to generate a trigger at a specified rate.
The EXSYNC signal can be selected as an output on any of the four camera control lines on the Camera Link™ connector. Note: The EXSYNC pulse is always fired from the selected trigger event. EXSYNC can be used as the exposure input to some area scan cameras. EXSYNC might also be used as the line transfer input on some linescan cameras. Sapera Parameters for EXSYNC: Refer to Time Integration method in the Sapera Acquisition Parameters Reference manual.
PRIN Pulse Generator Ext. Trigger PRIN Active Time Offset Figure 4: PRIN Pulse Generator The PRIN signal can be selected as an output on any of the four camera control lines on the Camera Link™ connector. Note: The PRIN pulse is always fired from the selected trigger event. Sapera Parameters for PRIN: Refer to Time Integration method in the Sapera Acquisition Parameters Reference manual. PRIN is typically designated by pulse #0 in the various time integration methods.
Area Scan Triggers The External Trigger allows image acquisition to be synchronized to external events. When acquiring an image in External Trigger mode, the acquisition will not start until the PC2-CamLink receives a trigger signal. Acquisition begins with the next valid frame after the trigger. A variety of trigger events can fire the EXSYNC and PRIN pulse generators for area scan cameras.
Let: t(et) = time of external trigger in μs t(vt) = time of validated trigger in μs t(d) = debounce circuit duration from 0 to 255μs We therefore get: t(vt) = t(et) – t(d) If: t(vt)> 0, then a valid trigger is detected and acquisition is fired Opto Formed by a LED emitter combined with a photo detector in close proximity, an opto-coupler (or opto-isolator) allows for the connection between the PC2-CamLink external trigger and the user circuitry using separate grounds.

Depending on the amount of light that is being emitted, the transistor can be turned ON, just like a switch.
other words, +5V is connected to Ext_Trig+ and the sink trigger source is connected to Ext_Trig-. This will normally require the application the invert the polarity of the trigger in the camera configuration file. Many TTL devices will not supply enough current to reliably drive the Ext_Trig+ of an opto-coupled input; a buffer is needed between the TTL output and the Ext_Trig+ input.

Shaft Encoder Web inspection systems with variable web speeds typically provide one or two synchronization signals from a web mounted encoder to coordinate trigger signals. The trigger signals are used by the acquisition linescan camera. The PC2-CamLink supports single or dual shaft encoder signals. Dual encoder signals are typically 90° out of phase relative to each other and provide greater web motion resolution.

User Timer PC2-CamLink offers a user timer that can be used to fire a line acquisition at a specified frequency. Note this user timer is asynchronous to all input pins. The line rate generated by the user timer ranges from 1μs to 65535μs in steps of 1μs. Virtual Frames Triggers Virtual frame is a method grouping a number of consecutive lines from a linescan camera into a frame buffer.

Strobe One strobe signal is available on pin 15 of the DB-15 connector (J2). The pulse duration and polarity are programmable (up to 65 seconds). The strobe signal is attained by using an LVT244 driver with the following electrical characteristics: Electrical parameters Description Value VOH typ Typical high-level output voltage 3.
delay parameter represents the time from the external trigger to strobe pulse assertion. In Slow Strobe mode, the strobe pulse occurs after a certain delay following the FVAL and the trigger, respectively. Strobe duration is programmable. See below for diagram. Basically, the strobe pulse is asserted from the first FVAL following the trigger. This mode is often used with free-running cameras. Slow Strobe Ext.
Serial Port The Camera Link™ cabling specification includes a serial communication port for direct camera control by the frame grabber. The PC2-CamLink supports this serial communication port either directly or by mapping it to a host computer COM Port. Any serial port communication program, such as Windows HyperTerminal, can connect to the camera in use and modify its function modes via its serial port controls.
Camera Interface The PC2-CamLink supports the Camera Link™ specification base configuration (one connector, 24bit data) and clock rates up to 66 MHz. The Camera Link™ specification also defines medium and full configurations with two and three connectors as well as a larger data size. The PC2-CamLink does not support the medium and full configurations. All signal and timing characteristics match the Camera Link™ specification. • The PC2-CamLink accepts up to 24-bit data in differential format.

Single Channel One channel presents the pixel data in sequential order. The acquired sequence represents the original image, without need of sorting or reformatting. The figure below (single channel) shows where the data appears in the original image. PC2-CamLink can support this format for pixel depths from 8-bit up to 16-bit. The IFC Software Library calls this “One Channel Left to Right” or CL2_1CHAN_L2R.
Dual-Channel Interline One channel carries the even lines, the other the odd lines. The lines are ‘interlaced’ in the original image. Data is presented simultaneously on both channels. The figure below (Interline) shows where the data appears in the original image. There are two options, as shown in the figure below. Channel A can present the even lines 0, 2, 4, 6, 8 or the odd lines 1, 3, 5, 7, 9. The PC2-CamLink can support this format for pixel depths from 8-bits up to 12-bits.

IFC IFC Support for YCrCb Engine: Create an image connection using IfxCreateImgConn()with the flag IFC_YCRCB_SINK or use IfxCreateImgSink() with the YCRCB_SINK flag. PCI Controller PCI controller has scatter-gather support to reduce CPU usage to a minimum. It retrieves a buffer descriptor list from host memory. The PCI controller can sustain an average transfer rate up to 100MB/second with bursts of 132MB/second.
Case 1: Line size below 4KB If the camera line dimension is smaller than 4096Bytes, the average line bandwidth must be used to evaluate if the camera’s bandwidth is acceptable for a FIFO-based frame grabber, such as the PC2CamLink. Line size = nb pixel/ lines * Bpp where Bpp is the number of bytes required to store each pixel. 8-bit pixels require 1 byte/pixel while the pixel depth of 10, 12, 14 or 16-bit/pixel requires 2 bytes/pixel.
Bandwidth Optimization Pixel Depth Truncation One of easiest techniques is to transfer only the eight most significant bits when the camera’s pixel depth is higher than 8-bits. If this compromise is acceptable, this will result in half the bandwidth required for the full pixel depth. PC2-CamLink has the ability to truncate the digital information to 8bits/pixel.
Visual Status LEDs PC2-CamLink hosts two visual status LEDs on its PCI bracket. They are labeled ACQ (acquisition) and TRIG (external trigger). The ACQ LED indicates the status of the acquisition based on the signals going through the Camera Link™ MDR-26 connector. Possible LED states are outlined in table below.
Parallel I/O PC2-CamLink provides digital I/O capability for controlling or monitoring external events. The digital input and output lines, available on the 26-pin header located at the top of the board, can be cabled to a 25-pin D-Sub connector that occupies an open slot in the PC chassis. The functionality of the I/O port is as follows: IN(7-0) Eight digital TTL input lines provide the capability to read these as either raw or latched (by STROBE_I) inputs.
Sapera support for Parallel I/O: Access to Parallel I/O is achieved using members of the SapGio class. Refer to Sapera++ Programmer’s manual for a complete description of the SapGio functions.
Acquisition Interrupts The PC2-CamLink provides acquisition interrupts that allow an application to monitor the acquisition status accurately. This is one of the many elements that frame the “trigger-to-image reliability” model supported by PC2-CamLink and its Acquisition and Control Unit (ACU).
Interrupt-Related Definitions Interrupt An interrupt is an electrical signal sent by the PC2-CamLink board to the computer CPU to indicate an event on the frame grabber. The PC2-CamLink driver has excellent reaction time to interrupts since interrupts are processed inside an interrupt service routine (ISR) at kernel level. Event An event is a WIN32 object that can take two states: signaled and nonsignaled. It is used for thread synchronization.
Start/End of Line For linescan cameras, the Start of Line interrupt represents the beginning of a valid line output by the camera. It is asserted on the LVAL pulse (at the beginning of the line). This is represented by CL2_INTR_HB in IFC. Sapera offers the End of line interrupt through the CORACQ_VAL_EVENT_TYPE_END_OF_NLINES event with N=1. Warning: Start/End of Line interrupts occur at a very high rate. This may saturate your CPU and prevent proper functioning of your OS.
End of PCI Transfer The End of PCI Transfer interrupt is generated when each frame or virtual frame has been transferred to host memory. In Sapera, CORXFER_PRM_EVENT_TYPE provides the various transfer events. The following are available on PC2-CamLink: -CORXFER_VAL_EVENT_TYPE_END_OF_FRAME -CORXFER_VAL_EVENT_TYPE_START_OF_FRAME -CORXFER_VAL_EVENT_TYPE_END_OF_LINE -CORXFER_VAL_EVENT_TYPE_END_OF_NLINES -CORXFER_VAL_EVENT_TYPE_END_OF_TRANSFER Under IFC, the end of transfer is represented by CL2_INTR_BMDONE .
Error Support Interrupts PC2-CamLink supports a number of interrupts generated when problematic conditions occur within the system. These interrupts are used to notify applications that something erroneous occurred. Error Support Interrupts are part of the “trigger-to-image reliability” support. Skipped Frame A Skipped Frame condition is signaled when the onboard FIFO is full resulting in the remainder of the current acquired frame to be discarded.
Camera Power PC2-CamLink can provide up to 1.5A of 5V or 12V power to the camera through the DB-15 connector. The voltage supply is dependent on the configuration of jumper J13. Refer to "J13: Power to Camera Voltage Selector" on page 72 for jumper settings. The floppy power connector J14 must be connected if your camera requires more than 0.5A. That is, if J14 is not connected, the PC2-CamLink will use power from the PCI connector to power the camera.
• • Error on Pixel Clock: No pixel clock detected from the camera. Visual indicators on the PCI bracket give a clear indication of the acquisition and trigger status. Additional LEDs are present at the back of the board, below the floppy power connector. These LEDs indicate a camera power overflow. The rest of trigger-to-image reliability is handled internally by the ACU to correctly synchronize acquisition with camera control and image transfer.

The advantages of the Camera Link™ interface are that it provides a standard digital camera connection specification, a standard data communication protocol, and simpler cabling between camera and frame grabber.
Data Port Summary The Camera Link™ interface has three configurations. A single Camera Link™ connection is limited to 28-bits requiring some cameras to have multiple connections or channels. The naming conventions for the three configurations are: • Base: Single Channel Link interface, single cable connector. • Medium: Two Channel Link interface, two cable connectors. • Full: Three Channel Link interface, two cable connectors.
Camera Controls Four LVDS pairs are reserved for general-purpose camera control, defined as camera inputs and frame grabber outputs. • Camera Control 1 (CC1) • Camera Control 2 (CC2) • Camera Control 3 (CC3) • Camera Control 4 (CC4) Note: the PC2-CamLink by default implements the control lines as follows (using DALSA Corporation terminology).

Sapera Software Example Grab Demo Overview Program Start•Programs•DALSA•Sapera LT•Demos•Grab Demo Program file \Dalsa\Sapera\Demos\Classes\vc\GrabDemo\Release\GrabDemo.exe Workspace \Dalsa\Sapera\Demos\Classes\vc\SapDemos.dsw Description This program demonstrates the basic acquisition functions included in the Sapera library. The program allows you to acquire images, either in continuous or in oneshot mode, while adjusting acquisition parameters.
Using the Grab Demo Server Selection Run Grab Demo from the Start Menu: Start•Programs•DALSA•Sapera LT•Demos•Grab Demo. When activated, Grab Demo first displays the “Acquisition Configuration” window. The first drop down menu allows you to select any installed Sapera acquisition server (that is, installed DALSA acquisition hardware using Sapera drivers). The second drop down menu allows you to select the available input devices present on the selected server.
Grab Demo Main Window The main window provides control buttons and a central region where the grabbed image is displayed. Developers can use the source code supplied with the demo as a foundation to quickly create and test the desired imaging application.
The various functions are described below: File Control Three controls are provided for image file transfers • New: Clears the current image frame buffer. • Load: Retrieves images in BMP, TIF, CRC, JPG, and RAW formats. • Save: Prompts for a file name, file save location, and image format. Acquisition Options Note that unsupported functions are grayed out and not selectable. Function support is dependent on the frame grabber hardware in use.
• Count and Size: Select the number of frame buffers and the image size here. • Type – Contiguous: Frame buffers are allocated in contiguous system memory (single memory block - no segmentation). • Type – Scatter-Gather: Frame buffers are allocated throughout system memory in noncontiguous memory (paged pool). Pages are locked in physical memory so a scatter-gather list can be constructed. This type allows for the allocation of very large size buffers or large buffer counts.
An important component of CamExpert is its live acquisition display window that 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 open the help file for more descriptive information on CamExpert.
Camera Files Distributed with Sapera The Sapera LT CDROM includes camera files that are compatible to PC2-CamLink supported cameras. When using CamExpert, you may use the camera files (CCA) provided to generate a camera configuration file (CCF) that describes the desired camera and frame grabber configuration. DALSA continually updates their camera application library that contains application information and prepared camera files.
Legacy files using the “.CVI” extension (CORECO VIDEO files) contain all operating parameters related to the frame grabber board, i.e., what the frame grabber can actually do with camera controls or incoming video. The Sapera parameter groups located within the file: • Activates and sets any supported camera control mode or control variable. • Defines the integration mode and duration. • Defines the strobe output control.

Troubleshooting Overview This section provides suggestions for resolving installation or usage problems that may be encountered with the PC2-CamLink due to the constant changing nature of computer equipment and operating systems. Note that information provided within this section will be updated with the latest information DALSA can provide for each manual version release.
Saving the Log • • • • Start Log Viewer From the menu bar select File•Save Messages… Select a filename (e.g., log.txt) Send log to DALSA Technical support Here is a typical log: Saving the PCI Diagnostics • • • • Start PCI Diagnostics Select the Save button. The dump of PCI configuration file is saved under PCIDUMP.TXT Send PCIDUMP.TXT to DALSA Technical Support Note that the DALSA PCI Vendor ID is 0x11EC. The PC2-CamLink board PCI Device ID is 0x2021.
Symptoms PC2-CamLink board not detected The board is not seen when an application is started. This is due to a module creation error under IFC or because the Sapera Server is not present under Sapera. Note: PC2-CamLink is supported by two different APIs: Sapera LT and IFC. You must install one or the other. It is not possible for PC2-CamLink to work under both APIs on the same machine. PC2CamLink will only work correctly with the last API installed on the machine.
Potential Hardware or PCI Failure • Make certain that the PC2-CamLink board is properly seated in the PCI slot. It is preferable to screw in the board securely to the computer chassis at the PCI bracket (some computer chassis use a clip mechanism instead of a screw). This ensures that the board remains stable when you connect/disconnect cables. • Make certain that the 3.3V (LED6) or 5V (LED5) LED is lit at the back of the board (below the floppy power connector).
• Open the registry editor. Click on Windows Start button and select ‘Run…’. In the Run dialog box, type ‘regedit’ (without the quotes) and click OK. This will start the registry editor. Go to the HKEY_LOCAL_MACHINE•SYSTEM•CurrentControlSet•Service•Pc2c folder. You should see the following key: • • Start REG_DWORD • 0x00000002 • If the Pc2c folder is absent, this indicates a problem with the installation process. Make certain that you have ‘Administrator’ privileges when you perform installation.
have not connected a floppy power cable from the PC power supply to the PC2-CamLink floppy power connector, do so if LED3 (12V overload) is lit. • Start the camera configuration tool (CamExpert for Sapera LT, or Camera Configurator for IFC) and select a suitable camera configuration file. Start the grab. The acquisition LED should blink rapidly (at about 15Hz) when the ACU is capturing valid data. Any error indication is reported by having the trigger LED turn red.

Glossary of Terms Bandwidth Describes the measure of data transfer capacity. A computer system’s PCI expansion bus is rated for a maximum peak data bandwidth of 132 MB/s. PCI devices must share the maximum PCI bus bandwidth when transferring data to and from system memory or other devices. Bus A common pathway, or channel, between multiple devices.
Frame buffer An area of memory used to hold a frame of image data. A frame buffer may exist on the acquisition hardware or be allocated by the acquisition hardware device driver in host system memory. Grab Acquiring an image frame by means of a frame grabber. Grayscale In image processing, the range of available brightness levels, displayed in shades of gray. In an 8-bit system, the gray scale contains values from 0 to 255. Host Refers to the computer system that supports the installed frame grabber.
(e.g., 8-bits, 15-bits, 24-bits) defines the number of gray levels or colors possible for each pixel. RGB A representation of color using the three primary colors (red, green, blue) as components. Video signals in RGB format are typically a non-composite video standard. A digital true color image can be represented by 8-bits per color (24-bits/pixel). Often image data is stored or transferred in 32-bits/pixel where the upper 8-bits of each pixel are unused.
