CN0561 A multi-channel data acqusition (DAQ) system measures a real world phenomenon such as temperature, force, acceleration, or vibration, converting measurements into digital values for data processing, storage, or transmission. A typical DAQ system is comprised of a sensor, analog filtering and signal conditioning circuitry, an analog-to-digital converter (ADC), and digital controller. CN0561 shown below is for High performance Piezo Accelerometer with Fault Protection. writeup
To begin using the evaluation board, take the following steps:
Add in any other details you want as well.
«ADD in a PICTURE» of the circuit block diagram, hardware image, or functional diagram. Please be sure to make the proper directory for images and other files related to this CN. If you need help doing so, please look online at Doku Wiki tutorials or ask someone who has done it before.
Add any and all connectors and options that customers can talk to or configure. Explain pinouts, provide part numbers for sensors you used, any third party equipment you connected so customers can replicate the setup which you tested & verified on.
Use an image here or a table with the reference designator and options
The chip select is configurable to be routed to 3 general purpose I/O pins of the board, digital pins 8, 9 and 10, allowing multiple boards using SPI communications protocol to be stacked up.
This could be a sensor specific requirement. (Optional) Point being, don't leave out details on the hardware config and capability.
The EVAL-CN0398-ARDZ shield board comes with a BNC connector J1 for pH sensors as shown on the image below
The output of the pH sensor is bipolar and gives a maximum signal of ±414 mV at 25°C. The AD7124-8 operates from a single power supply therefore the pH probe should be biased above ground so that it is within the acceptable common-mode range of the AD7124-8. One of the integrated features of the AD7124-8 is its internal bias voltage generator that sets the common mode voltage of a channel to AVDD/2, or 1.65 V. This bias voltage from the ADC is applied to the pH probe shield and sets the output of the sensor 1.65 V ±414 mV at 25°C. For information about pH calibration, visit CN0398 Circuit Note.
Are there any switches or reset buttons, describe them.

Your board may be more or less complicated, so just ensure that you talked about everything that a customer would want to know about and change.
Terminal block P3 is the power supply input (input range:+9.5V to +36V DC). The EARTH terminal can be connected to an external earth connection, to the GND terminal or left floating if an external earth connection is not used.
