Functional Block Diagram

See Figure 1 for the circuit block diagram and see the EVAL-

CN0349-PMDZ-Altium DesignerSchematic.pdf file for the

circuit schematics. This pdf file is located in the CN-0349

Design Support Package. A block diagram of the test setup is

shown in Figure 9.

Setup

For proper setup, take the following steps:

1. Connect the EVAL-CFTL-6V-PWRZ (6 V dc power supply)

to the SDP-PMD-IB1Z interposer board via the dc barrel jack.

2. Connect the SDP-PMD-IB1Z interposer board to the

EVAL-SDP-CB1Z SDP board via the 120-pin Connector A.

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

the USB cable.

4. Connect the EVAL-CN0349-PMDZ evaluation board to

the SDP-PMD-IB1Z interposer board via the 8-pin header

IMOD connector cable supplied with the CN-0349 board

(4-pin MTE cable, Digilent, Inc.).

Connect the conductivity cell to the EVAL-CN0349-PMDZ

evaluation board via the J1 terminal block. A photo of the

EVAL-CN0349-PMDZ board is shown in Figure 10.

Test

Launch the CN-0349 Evaluation Software. The software will be

able to communicate with the SDP board if the Analog Devices

SDP drivers are listed in the Device Manager. When USB

communications are established, the SDP board is used to send,

receive, and capture serial data from the EVAL-CN0349-PMDZ

board. Data, information, and details regarding how to use the

evaluation software for data capturing can be found in the

CN-0349 Software User Guide.
