Equipment Required

The following equipment is needed:

•

A PC with a USB port and Windows® XP and Windows®

Vista (32-bit), or Windows® 7 (32-bit)

•

EVAL-CN0326-PMDZ circuit evaluation board

•

EVAL-SDP-CB1Z circuit evaluation board

•

SDP-PMD-IB1Z SDP interposer board

•

CN0326 Evaluation Software

•

Power supply: 6 V wall wart or equivalent

•

Yokogawa 2000 Precision DC Power Supply or

equivalent

Getting Started

Load the evaluation software by placing the CN-0326 Evaluation

Software disc in the CD drive of the PC. Using "My Computer,"

locate the drive that contains the evaluation software disc and

open the Readme file. Follow the instructions contained in the

Readme file for installing and using the evaluation software.

Setup

The CN0326 evaluation kit includes self-installing software on a

CD. The software is compatible with Windows® XP (SP2) and Vista

(32-bit and 64-bit). If the setup file does not run automatically,

you can run the setup.exe file from the CD.

Install the evaluation software before connecting the evaluation

board and SDP board to the USB port of the PC to ensure that

the evaluation system is correctly recognized when connected to

the PC.

1. After installation from the CD is complete, power up the

SDP-PMD-IB1Z evaluation board as described in the

Power Supplies Configuration section. Connect the SDP

board (via either Connector A) to the SDP-PMD-IB1Z

evaluation board and then to the USB port of the PC

that will be used for evaluation using the supplied cable.

2. Connect the 12-pin right angle male pin header of the

EVAL-CN0326-PMDZ to the 12-pin right angle female

pin header of the SDP-PMD-IB1Z.

3. Before running the program shown in Figure 9, connect

the pH probe at the BNC terminal and the RTD sensor

to the terminal jack of the EVAL-CN0326-PMDZ.

4. After all the peripherals and power supply are all

connected and turned on, click Connect on the GUI

shown in Figure 9. When the evaluation system is

successfully detected by the PC, the EVAL-CN0326-

PMDZ circuit board can now be evaluated using the

software shown in Figure 9.

Functional Block Diagram

The functional block diagram of the test set-up is shown in

Figure 8. The test set-up should be connected as shown. A

screenshot of the main software window is shown in Figure 9.

Power Supply Configuration

The SDP-PMD-IB1Z must be supplied with 6 V dc power

supply and its jumper, JP1, should be set to 3.3 V to give power

to the EVAL-CN0326-PMDZ.
