=====================================
A. Installing the DPT Device Driver
=====================================
If you are updating DPT software from version 1.1.1 or higher,
please read section B, "Updating the DPT Device Driver".
If you are upgrading DPT software from version 0.06 or earlier,
please read section C, "Replacing Old DPT4 Device Driver".
If this is the first time the DPT software has been installed
in your system, and DPT boards are installed in the computer,
Windows will have opened one or more "Found New Hardware Wizard"
dialog boxes (one for each board) when you first logged on.
For Windows 2000 installations, the device driver is installed
directly into the system's device driver folder. 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. When the system is rebooted and you log
back on, Windows will detect the new DPT devices and should
automatically install the device driver for them. If for some
reason it does not, or if you prefer not to reboot the system,
you can follow the steps outlined, below.
Installation using the Device Manager:
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 DPT board. Cancel any others
that appear for additional boards.
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. Depending on the version of the OS, this
will open a window with tabs titled, "System Properties",
or a windows with links, titled, "System".
4. For the "System Properties" window, choose the tab labeled
"Hardware" and then click on the "Device Manager" button.
For the "System" window with links, click on the link for
"Device Manager" under the "Tasks" heading.
5. The "Device Manger" window lists the devices currently
installed in the system. The list should include 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".
6. For each "PCI Device" listed, right click on the device
and select "Update driver" or "Update driver software"
command from the menu that appears. Depending on the
OS version, this will open a "Hardware Update Wizard"
or "Update Driver Software" window.
7a. For the "Hardware Update Wizard" window, you may be
asked about connecting to Windows Update". Select
"No not this time" and click the "Next" button.
In the next pane, choose "Install from a list or
specified location". Click "Next".
In the next pane, choose "Search for the best driver...".
Unselect "Search removable media...".
Select "Include this location in the search".
7b. For the "Update Driver Software" window, click on
"Browse my computer for driver software".
7c. For either window (OS) type continue by clicking the
"Browse" button and navigate to select "C:\cac\dpt\driver".
If you chose a different location to install the DPT
software, replace "C:\cac" with the folder you chose.
Click "Next" and the system will install the driver
for the device selected in step 6.
8. Repeat steps 6 and 7 for all of the "PCI Device" entries in
the "Device Manager" window. If any of them are not
DPT boards, the driver won't load.
9. 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.

one or more devices named, "cacdpt4 Device".
6. 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 "Cacdsp 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 DPT 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 DPT Flash Memory
====================================
The DPT 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 DPT 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
DPT 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 DPT Boards
====================================
The channelization functionality of DPT boards will not work
before DPT 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 DPT 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
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
