EVALUATION BOARD SOFTWARE
INSTALLING THE SOFTWARE
The EVAL-AD7400/AD7401 evaluation kit includes self-
installing software on CD, for controlling and evaluating
the performance of the AD7400 or AD7401 when it is
operated with the EVAL-CED1Z. The software is compatible
with Windows® 2000/XP. If the setup file does not run
automatically, setup.exe can be run from the CD.
When the CD is inserted into the PC, an installation program
automatically begins. This program installs the evaluation
software. The user interface on the PC is a dedicated program
written especially for the AD7400 or AD7401 when operating
with the EVAL-CED1Z.
Note that the software should be installed before the USB cable
is connected between the EVAL-CED1Z and the PC.
This ensures that the appropriate USB driver files have been
properly installed before the EVAL-CED1Z is connected to the PC.
When the software is run for the first time with EVAL-CED1Z
connected to the PC, the PC automatically finds the new device
and identifies it. Follow the on-screen instructions that appear
automatically. This installs the drivers for the EVAL-CED1Z on
the PC. If an error appears on screen when the software is first
opened, then the PC does not recognize the USB device.
Correct this error with the following steps:

Click the My Computer icon, then select Properties.
When the System Properties window opens, select the
Hardware tab.
Click Device Manager in the Hardware Tab of the System
Properties window.
Examine the devices listed under the Universal Serial Bus
Controller heading.
If an unknown device is listed, right click this option and
select Update Driver.
The New Hardware Wizard runs twice. Under ADI
Development Tools, the hardware is listed as ADI Converter
Evaluation and Development Board (WF).
Reboot your PC.

SETTING UP THE EVAL-CED1Z
This section describes how the evaluation board, the EVAL-
CED1Z, and the software should be setup to begin using the
complete system.

Install the EVAL-AD7400/AD7401 software.
Connect the EVAL-CED1Z board and the evaluation
board via the SPORT connector. Apply power to the
EVAL-CED1Z via the 7 V, 15 W power supply provided.
At this stage, the green LED labeled Power, on the EVAL-
CED1Z, should be lit indicating that the EVAL-CED1Z is
receiving power.
The USB cable can then be connected between the PC and
the EVAL-CED1Z. A green LED positioned beside the USB
connector on the EVAL-CED1Z board lights up indicating
that the USB connection has been established.
The EVAL-AD7400/AD7401 is detected. Proceed through
any dialog boxes that may appear (use the recommended
options) to finalize the installation.
Start the EVAL-AD7400/AD7401 software. The FPGA on
the EVAL-CED1Z is automatically programmed when the
software is opened. The two red LEDs (D14 and D15) on
the EVAL-CED1Z now light up. This indicates that the
EVAL-CED1Z is functional and ready to receive instructions.
