EVALUATION BOARD SETUP PROCEDURES

The AD7903 evaluation board connects to the (EVAL-SDP-CB1Z)

system demonstration board. The EVAL-SDP-CB1Z board is

the controller board, which is the communication link between

the PC and the main evaluation board.

Figure 1 shows a photograph of the connections made between

the EVAL-AD7903SDZ daughter board and the EVAL-SDP-CB1Z

motherboard.

Connecting the Evaluation and SDP Boards to a PC

1. Install the AD7903 software. Ensure that the EVAL-SDP-CB1Z

board is disconnected from the USB port of the PC while

installing the software. The PC must be restarted after the

installation is complete.

2. Before connecting power, connect the 120-pin connector, J5,

of the EVAL-AD7903SDZ board to Connector J4 on the

EVAL-SDP-CB1Z board. Nylon screws are included in the

EVAL-AD7903SDZ evaluation kit and can be used to

ensure that the EVAL-AD7903SDZ and EVAL-SDP-CB1Z

boards are connected firmly together.

3. Connect the 9 V power supply adapter included in the kit

to the EVAL-SDP-CB1Z.

4. Connect the EVAL-SDP-CB1Z board to the PC via the

USB cable. (If you are using Windows® XP, you may need to

search for the EVAL-SDP-CB1Z drivers. Choose to auto-

matically search for the drivers for the EVAL-SDP-CB1Z

board if prompted by the operating system.)

Verifying the Board Connection

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 connected 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. From

the list of System Tools, click Device Manager.

b. Under ADI Development Tools, Analog Devices

System Development Platform SDP-B should appear

(see Figure 15), indicating that the EVAL-SDP-CB1Z

driver software is installed and that the board is

connected to the PC correctly.
