HOW TO USE THE SOFTWARE
SETTING UP THE SYSTEM FOR DATA CAPTURE:
BOARD OPERATION/CONNECTION SEQUENCE
With the evaluation software installed, the following board
operation/connection sequence can be used:
1. Connect the SDP controller board to the evaluation board
via the J5 connector (screw into place as required). The
software is configured to find the evaluation board on either
the J4 or J5 connector of the SDP board.
2. Power the board with the appropriate supply, as described
in the Power Supplies section.
3. Connect the EVAL-SDP-CB1Z board to a PC using the
USB cable.
4. Start the evaluation software. Click Start > All Programs >
AD7902_03_Evaluation > AD7902_03_Evaluation_
Software.
5. Apply a signal source and capture data.
STARTING THE SOFTWARE
When the software starts running, it searches for hardware
connected to the PC. The software automatically detects the
generic attached to the PC, or you can choose to run the software
in standalone mode without any hardware connected.
With Hardware Connected
To run the program with hardware connected,
1. Click Start > All Programs > AD7902_03_Evaluation >
AD7902_03_Evaluation_Software. (To uninstall the
program, click Start > Control Panel > Add or Remove
Programs > AD7902_03_Evaluation.)
2. If the SDP board is not connected to the USB port when
the software is launched, a connectivity error displays (see
Figure 17). If a connectivity error is displayed, connect the
evaluation board to the USB port of the PC, wait a few
seconds, click Rescan, and follow the instructions.

3. After finding the evaluation board, the software connects
to the board and displays the dialog box shown in Figure 18.

4. After the board is correctly detected, the main window of
the software appears (see Figure 21), showing that the
EVAL-AD7902SDZ board is connected.
Without Hardware Connected
The software can run in standalone mode when no evaluation
board hardware is connected to the USB port.
1. Click Start > All Programs > AD7902_03_Evaluation >
AD7902_03_Evaluation_Software.
2. The software automatically seeks to find the hardware
connected; therefore, when no hardware is connected, a
connectivity error is displayed (see Figure 19). If you wish to
continue without hardware in standalone mode, click Cancel.

3. The software alerts the user that no hardware is connected
and that the software is going to continue in standalone mode.
