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

with 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 >

AD7903_03_Evaluation > AD7903_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 > AD7903_03_Evaluation >

AD7903_03_Evaluation_Software. (To uninstall the

program, click Start > Control Panel > Add or Remove

Programs > AD7903_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.

Figure 18. Software Connects to SDP Board

4. After the board is correctly detected, the main window of

the software appears (see Figure 21), showing that the

EVAL-AD7903SDZ 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 > AD7903_03_Evaluation >

AD7903_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.
