Figure 4. Test Setup Block Diagram

Setup

Connect the 120-pin connector on the EVAL-CN0274-SDPZ to

the connector on the EVAL-SDP-CS1Z. Use nylon hardware to

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

ends of the 120-pin connectors.

With power to the supply off, connect a 3.0 V power supply to the

J3 connector. Alternatively, Connector J2 can be used on the

bottom of the PCB to power the entire circuit off two AAA

batteries. Connect the USB cable supplied with the EVAL-SDP-

CS1Z to the USB port on the PC. Note: Do not connect the USB

cable to the mini-USB connector on the SDP board at this time.

Test

Apply power to the J3 screw terminal or place batteries in the J2

connector on the bottom of the PCB batteries (move Jumper J6

to the left-hand position for battery operation). Launch the

CN0274 evaluation software and connect the USB cable from

the PC to the mini-USB connector on the EVAL-SDP-CS1Z.

Once USB communications are established, the EVAL-SDP-CS1Z

can now be used to send, receive, and capture serial data from

the EVAL-CN0274-SDPZ.

Information regarding the EVAL-SDP-CS1Z can be found in

the SDP User Guide.

Information and details regarding test setup and calibration, and

how to use the evaluation software for data capture can be found in

the software Readme file found at: www.analog.com/CN0274-

UserGuide.
