General Setup
The following sections describe the steps for setting up the EV-ISO-4224-FMCZ Reference Design Board using ZedBoard™.
Reference Design Kit Contents
- EV-ISO-4224-FMCZ : ADAQ4224 Reference Design Board with Digital Signal and Power Isolation
- Micro-SD card with adapter containing system board software and Linux OS
Equipment
- Zedboard™ Rev 1.0 or later board
- DC/AC signal source (Audio Precision or similar high performance signal source)
- SMA cables
- XLR-SMA interposer board
- SD Card (included in the reference design board kit)
- Micro-USB to USB type A cable (optional)

General Description
The EV-ISO-4224-FMCZ is an isolated digital and power reference design for the ADAQ4224, a 24-bit, 2MSPS μModule Data Acquisition Solution. On the EV-ISO-4224-FMCZ, the electrically isolated temperature sensor of the ADAQ4224 is connected to the controller side and has a separate ground potential versus the data acquisition signal path ground. The EV-ISO-4224-FMCZ has the power management blocks to generate all the necessary supply rails and reference voltage for the operation of the ADAQ4224 μModule.

Getting Started
The following section contains the software installation instructions together with the hardware configurations necessary to use the EV-ISO-4224-FMCZ.
Software Installation Procedures
Download the Analysis/Control/Evaluation (ACE) Software installer from the Analog Devices website.
To ensure that the evaluation system is correctly recognized when it is connected to the PC, install the ACE and the ADAQ4224 ACE Plug-in first before connecting the EV-ISO-4224-FMCZ and ZedBoard™ to the PC.
Hardware Connection
The EV-ISO-4224-FMCZ connects to the ZedBoard™. The ZedBoard™ serves as the communication link between the PC and EV-ISO-4224-FMCZ. Figure 2 shows the connections between the EV-ISO-4224-FMCZ, the ZedBoard™ and the signal source.
Figure 2. Hardware Evaluation Setup
- Configure the P1 & P2 links on the EV-ISO-4224-FMCZ. Short pin 1 and pin 2 for both P1 and P2 jumper links.
- Configure the VADJ and Boot links on the ZedBoard™ as shown on Figure 3.
- Connect the EV-ISO-4224-FMCZ securely to the 160-way connector on the ZedBoard™. The EV-ISO-4224-FMCZ does not require an external power supply adapter.
- Connect the ZedBoard™ USB_OTG port to the PC, this micro USB to USBA cable is included on the ZedBoard™ kit. Power it up with the 12 V wall adapter included in the kit.

Software GUI Setup
Launching the Software
After installing ACE (see the Software Installation Procedures section), run the software with either of the following methods:
- Navigate to the destination folder of the ACE installer selected during the installation procedure and run the ACE.exe file.
- Search for ACE in the Start Menu and run the software.
- Click on the ACE.exe Desktop Shortcut
Figure 4. Launching ACE.exe from Start Menu
ACE Main Window
- The EVAL-ADAQ4224-FMCZ icon should be detected in the main window once the Zedboard powers-up and LD0 is blinking. Click Refresh Attached Hardware if the icon is not seen.
- Click on the EVAL-ADAQ4224-FMCZ icon to open up the Board View.

Board View
- The ADAQ4224 Communication Mode is selected in the CONFIGURATION Panel in the Board View window. The default mode is Single-Lane/24-bit output data coding/SPI mode/Single Data Rate
- Click on the either the ADAQ4224 or TEMP SENSE icon to open the Chip view for the ADAQ4224 ADC or the ADAQ4224 Temperature Sensor
- Table 1 shows the maximum sampling frequency that can be set for each communication mode. Note that this is a limitation on the Zedboard, not the ADAQ4224.

- The no. of samples per capture can be set in this window.
- A Coherency calculator can also be used to calculate for a coherent input frequency with respect to the set sampling frequency and no. of samples.
- There are different tabs that can be selected to perform a waveform capture, an FFT capture and a histogram capture.
