In addition, it has the 8 digital Inputs and 8 digital outputs for external controls. The operation of the board is controlled by program API, figure [1-1] shows connection of the system (usually PC). [Figure 1-1. PCIe-FRM11 board Usage] As shown in Figure [1-1], the PCIe-FRM11 is inserted into any available PCI Express slot in your PC. It receives Image Frame from camera via Camera-Link Standard Interface. And, received data transmit to the API through PCI Express x1 interface

Primary functions are receiving the image frame data, transmitting/receiving UART data and controlling 8 bit digital inputs, and 8 bit digital outputs. However, it supports 5 bit digital inputs and 8 bit digital outputs for external interface with Dsub15 port. [Figure 2-1. Functional Block Diagram] -6-

FPGA Block Diagram] The core logic program of the FPGA is loaded by JTAG. It saves a program at the FPGA Program Logic and loads when power-up. PCIe-FRM11 supports Camera Link Base Configuration. Base Configuration consists of 4 LVDS signal lines that serialize 28 bit parallel signals including 24 data bits and 4 enable signals Frame Valid, Line Valid, Data Valid, and a spare, and one LVDS signal line to synchronize with camera, Asynchronous serial communication for communicating with the camera, including four CC (Camera Control) signals. All 11 LVDS signal lines, including two LVDS lines, are transmitted over the MDR cable. The transmitted signal is deserialized through the Channel Link chip in the PCIe-FRM11 into four image LVDS serial signals into a 28-bit parallel video signal and control signals (Frame Valid, Line -7-

8 Valid, Data Valid, and a spare). In addition, a clock signal is generated by one LVDS to synchronize the signal between the camera and the PCIe-FRM11, and the remaining camera control signals and communication signals are converted into a general TTL signal level. Camera Control CCx+ The above picture shows the camera control output circuit that can send the control signal from the PCIe-FRM11 board to the camera via the camera-link cable. All four digital outputs are output through Differential method. Each output is mapped to a digital output and output. Each bit position is shown in [Figure 2-3] below.

If any of these items is missing or damaged, contact DAQ system. - PCIe-FRM11 board - CDROM (drivers/manual/api/samples etc.) After unpacking, inspect the board carton to make sure there are no damages on the board. 4.2 Installation Sequence To install your PCIe-FRM11 board in your PC, follow the steps described in the document How to install PCI DAQ Board provided by DAQ System. If the document is missing, you can get it from The PCIe-FRM11 board is completely Plug & Play. There are no switches or jumpers to set. Therefore you can install it easily. - Your OS requirement : Windows 2000 SP4 or Windows XP SP1 above The PCIe-FRM11 connects to Express Card Port. After that you can show the below picture of New Hardware Search Wizard window. If new hardware is found, Wizard will ask you to install the corresponding driver. For installation of the driver, select the item Install from a list or specific location (Advanced) and

22 click Next as in the figure

23 If the installation is completely finished, you confirm it in the following ways. Do the following steps to show up the Device Manager window. [My Computer -> properties -> Hardware -> Device Manager -> Multifunction Adaptors -> PCIe-FRM11] [Figure 4-1. Select My computer -> Properties ]

25 [Figure 4-3. Device Manager window] If you can see the PCIe-FRM11 at Multifunction Adaptors, the driver installation is to have been over. (Check the red circle) Important Notice : After installation, you should re-boot the system for the proper operation

26 5. Sample Program. DAQ system provides a sample program to make the user be familiar with the board operation and to make the program development easier. You can find the sample program in the CDROM accompanying with the board. One of the execution file is FrmTest.exe. It stores the frame data to memory or hard-disk and displays it to Hexa-decimal values which can utilize necessary frame data to developers. The other is FRM11_TEST.exe. This programs sets the DVAL or HVAL for valid data line. Sample program is provided in source form in order to show the usage of API(Application Programming Interface) of the board and may be modified for customer s own usage. 5.1 FrmTest Program [Figure 5-1. When Sample program FrmTest.exe is executed]

27 To run the sample application program, you need to use API, it is a form of client DLL. To compile the sample source to make its executable file, you have to use Import Library files and header files. You can find them in the CDROM. To run the.exe file, the API DLL file (PCI_FRM11.DLL) must be in the same directory with the.exe file or Windows system folder. Another method is to add the directory of API DLL file to PATH environmental variable. [Figure 5-1] Execution sequence for sample program as shown below Device Init click Start click Get Info.

It is performed using the sample program FrmTest.exe on PC equipped with the PCIe-FRM11 board. Photo coupler Interface Circuit Image Frame Simulator PCIe-FRM11 BOARD Camera Link [Figure 6-1. Equipment Connection for Testing] Figure [6-1] shows connection of the equipments. Although the PCIe-FRM11 is shown outside the PC in this figure, but actually it is located in a PCI slot inside the PC. The image frame data is generated in the Image Frame Simulator made by DAQ System. If you have real camera or a frame source, you can use it. At this connected state, turn the all power on and execute test program ( FrmTest.exe ) on the PC. Follow the steps to test the function of receiving image frame data

35 Step 1. : Press the LVDS init button to initialize the LVDS circuit and then press the Start button to save Image Frame data. Step 2 : Press the Frame Read button. Then data are displayed on editor box. Compare the contents of the editor box with the data of the Image Frame Simulator. Comparison can be performed using the Save to button. It saves the contents of the editor box to a file. 6.2 UART Tx/Rx Test At the above stage, make the image frame simulator to send UART data to PCIe-FRM11 board periodically. Step 1 : Press the UART init button to initialize the UART and then press the Start Timer to get the UART data from the Image Frame Simulator. Then the gotten data are displayed on the editor box below the button. Compare the contents of the editor box with the data of the Image Frame Simulator. Step 2 : Write the data to the editor box beside the Send Serial Data button and press the Send Serial Data button to send it to the Image Frame Simulator via the UART. Compare the data on the editor box with that of the Image Frame Simulator. 6.3 DIO Input/Output test Continue the test from the previous stage. Step 1 : Step 2 : After to make all the output port 1 using DIO Write function of the test program, check the output state using the oscilloscope. To check photo-coupler output, you have to prepare some external circuit. Using DIO read function, read out each input state. To make some activation of the photocoupler input, you need to prepare some external circuit
