Getting Started

Load the evaluation software by placing the CN-0229 evaluation

software CD into the CD drive of the PC. Using My Computer,

locate the drive that contains the evaluation software CD and

open the Readme file. Follow the instructions contained in the

Readme

file for installing and using the evaluation software.

Functional Block Diagram

Figure 5 shows a functional block diagram of the test setup. The

EVAL-CN0229-PADSSchematic

pdf file contains the detailed

circuit schematics for the CN-0229 evaluation board. This file

Setup

Connect the 120-pin connector on the EVAL-CN0229-SDPZ

circuit board to the CON A connector or the CON B connector

on the EVAL-SDP-CB1Z (SDP) board. Use nylon hardware to

firmly secure the two boards, using the holes provided at the

ends of the 120-pin connectors. After successfully setting the dc

output supply to +15 V, −15 V, and +6 V output, turn the power

supply off.

With power to the supply off, connect a +15 V power supply to

+15 V pin of CN1, a −15 V power supply to the −15 V pin of

CN1, and GND to the GND pin of CN1. Connect +6 V to CN2

the same way. Turn on the power supply and then connect the

USB cable with the SDP board to the USB port on the PC. Note:

Do not connect the USB cable to the Mini-USB connector on

the SDP board before turning on the dc power supply for the

EVAL-CN0229-SDPZ.
