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.
Circuit Note
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.
