This document describes procedures for the installation
and updating of CAC DPT device driver on 32-bit Windows
versions XP and later.
Unlike earlier releases, the device driver for Windows XP
and later is now authenticated using a digital signature
and must be installed or updated using the system's device
manager, as described below.
This document also discusses updating the flash memory and
initialization if DPT channelization.
The procedures described herein assume that the DPT
hardware (the boards, themselves) are already installed
in your system.
This document includes the following sections:
A. Installing the DPT Device Driver
- for "First Time" installation.
B. Updating the DPT Device Driver
- for upgrades from previous
release versions.
C. Updating the DPT Flash Memory
- for all DPT software installs or upgrades.
D. Initializing DPT Boards
- for all DPT software installs or upgrades.
=====================================
A. Installing the DPT Device Driver
=====================================
If you are updating DPT software from a previous software release,
please read section B, "Updating the DPT 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.
Click on the "Cancel" button of this wizard if you have not
already. This will abort the wizard for the first DPT board.
Cancel any others that appear for additional boards.
Install the device driver using the Device Manager:
1. Open the Control Panel from the Windows "Start" button,
select "Settings" then "Control Panel".

software, replace "C:\cac" with the folder you chose.
Click "Next" and the system will install the driver
for the device selected in step 5.
7. Repeat steps 5 and 6 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.
8. Close the "Device Manager", "System Properties" and
"Control Panel" windows.
You should now continue with sections C and D 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.

You should now continue with sections C and D 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.
====================================
C. 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.
====================================
D. Initializing DPT Boards
====================================
The channelization functionality of DPT boards will not work
before DPT boards are initialized.
From a command shell window (see section C) 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.
