Circuit Note
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
is contained in the CN-0229 Design Support Package:

CN-0229
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.
