CN-0326
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.

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.
