This document describes procedures for the installation and updating of CAC DPT4 device driver. It also discusses updating the flash memory and initialzation if DPT4 channelization. The procedures described herein assume that the DPT4 hardware (the boards, themselves) are already installed in your system. This document includes the following sections: A. Installing the DPT4 Device Driver - for "First Time" installation. B. Updating the DPT4 Device Driver - for upgrades FROM software release 1.1.1 or higher. C. Replacing Old DPT4 Device Driver - for upgrades FROM software pre-release versions 0.06 or earlier. D. Updating the DPT4 Flash Memory - for all DPT4 software installs or upgrades. E. Initializing DPT4 Boards - for all DPT4 software installs or upgrades. ===================================== A. Installing the DPT4 Device Driver ===================================== If this is the first time a DPT4 software has been installed in your system, and DPT4 boards are installed in the computer, Windows will have opened a "Found New Hardware Wizard" dialog box when you first logged on. In this case, the easiest method to complete the device driver installation is to reboot the system. Rebooting is also necessary to ensure that any new environment settings become effective. If you are updating DPT4 software from version 1.1.1 or higher, please read section B, "Updating the DPT4 Device Driver". If you are upgrading DPT4 software from version 0.06 or earlier, please read section C, "Replacing Old DPT4 Device Driver". To reboot the system click on the Windows "Start" button and select "Shut Down". In the dialog that appears choose "Restart" from the pulldown menu and click "OK". When the system is rebooted and you log back on, Windows will detect the new DPT4 devices and should automatically install the device driver for them. If you prefer not to reboot you can follow these steps to complete the device driver installation: 1. Click on the "Cancel" button of the "Found New Hardware Wizard" if it is still on your screen. This will abort the wizard for the first DPT4 board. Additional DPT4 devices will be installed automatically. 2. Open the Control Panel from the Windows "Start" button, select "Settings" then "Control Panel". 3. From the "Control Panel" window select and run the "System" control panel. This will open a window titled, "System Properties". 4. In the "System Properites" window, choose the tab at the top labeled "Hardware". 5. Click on the "Device Manager" button. This will open the "Device Manger" window. The "Device Manager" window lists the devices currently known by the system. 6. In the list of device types displayed there should be an item named "Other devices". Expand the list (if necessary) by clicking the "+" to the left of "Other devices". This should reveal one or more devices named, "PCI Device". 7. For each "PCI Device" listed in step 6, right click on the device and select "Uninstall" from the menu that appears. Click "OK" in the "Confirm Device Removal" window. 8. Repeat step 7 for all of the "PCI Device" entries in the "Device Manager" window. 9. In the upper left-hand corner of the "Device Manager" window click on "Action" and in the menu that appears and select "Scan for hardware changes". 10. The computer will scan for new hardware and should detect and install the DTP4 devices. A device type labeled "CACDSP" with devices labeled "DPT4" should then appear in the list of devices. 11. Close the "Device Manager", "System Properties" and "Control Panel" windows. You should now continue with sections D and E in this document. You can re-open this document found in the file dpt\driver\drv_info.txt which is located in the folder you installed the DPT software into. ==================================== B.

For each "cacdpt4 Device" listed in step 5, right click on the device and select "Uninstall" from the menu that appears. Click "OK" in the "Confirm Device Removal" window. 7. Repeat step 6 for all of the "cacdpt4 Device" entries in the "Device Manager" window. When the last of these is removed the device type named "cacdspt Device" will also be removed. 8. Reboot the system. Click on the Windows "Start" button and select "Shut Down". In the dialog that appears choose "Restart" from the pulldown menu and click "OK". When the system is rebooted and you log back on, Windows will detect the new DPT4 devices and should automatically install the device driver for them. You should then continue with sections D and E in this document. You can re-open this document found in the file dpt\driver\drv_info.txt which is located in the folder you installed the DPT software into. ==================================== D. Updating the DPT4 Flash Memory ==================================== The DPT4 boards include flash memory which stores FPGA configuration data and program code for the MIPS processor. This software release may include updates for the flash data. To ensure that the DPT4 boards are up to date run the dpflashup program from a command shell window. Click on the Windows "Start" button and select "Run". In the dialog that opens there is a text line labeled "Open" into which you should type the word, "cmd", (without the quotes). Then click the "OK" button. This should open a command shell window. In the command shell window run the dpflashup program by typing dpflashup all Hit the "Enter" key on the keyboard. The program will compare the code versions in the flash of each DPT4 board with the versions supplied with the new software release. Any new versions will be loaded in the flash memory. In some cases, depending on which flash data is updated, the changes will not take effect until the system is power-cycled. The dpflashup program will display a message about this if a power-cycle is required. ==================================== E. Initializing DPT4 Boards ==================================== The channelization functionality of DPT4 boards will not work before DPT4 boards are initialized. From a command shell window (see section D) run the dpinit program as shown below. dpinit The dpinit program starts the MIPS processor running on all of the DPT4 boards found in the system. For each board initialized the program will display the word "Done". It takes a few seconds for the MIPS processor to initialize the channelization software on the board. This program needs to be run each time the system is turned on. You may want to add the dpinit command to a startup script for your login session. It does not hurt to run the command more than once. When run a second time it first halts the MIPS processor and then restarts it to do a full initialization.Download Driver Pack
