SETTING UP THE SYSTEM FOR DATA CAPTURE
After completing the steps in the Software Installation
Procedures and Evaluation Board Hardware sections, set up the
system for data capture as follows:
1. Allow the Found New Hardware Wizard to run after the
EVAL-SDP-CB1Z board is plugged into your PC. (If you
are using Windows XP, you may need to search for the
EVAL-SDP-CB1Z drivers. Choose to automatically search
for the drivers for the EVAL-SDP-CB1Z board if prompted
by the operating system.)
2. Check that the board is connecting to the PC correctly
using the Device Manager of the PC.
a. Access the Device Manager as follows:
i. Right-click My Computer and then click Manage.
ii. A dialog box appears asking for permission to
allow the program to make changes to your
computer. Click Yes.
iii. The Computer Management box appears. Click
Device Manager from the list of System Tools
(see Figure 18).
b. The EVAL-SDP-CB1Z board should appear under
ADI Development Tools. This indicates that the
driver software is installed and that the board is
connecting to the PC correctly.

Launching the Software
After completing the steps in the Setting Up the System for Data
Capture section, launch the AD7176-2 software as follows:
1. From the Start menu, select Programs > Analog Devices
> AD7176-2 > AD7176-2 Evaluation Board Software.
The main window of the software then displays.
2. If the AD7176-2 evaluation system is not connected to the
USB port via the EVAL-SDP-CB1Z when the software is
launched, a connectivity error displays (see Figure 19).
Connect the evaluation board to the USB port of the PC,
wait a few seconds, click Rescan, and then follow the on-
screen instructions.
Figure 19. Connectivity Error Alert
When the software starts running, it searches for hardware
connected to the PC. A dialog box indicates when the generic
SDP attached to the PC is detected, and then the main window
appears (see Figure 20).
