Figure 1 AD-APARDSPOE-SL

The AD-APARDSPOE-SL is a 10BASE-T1L power extractor with Single Pair Power over Ethernet (SPoE) for development of field devices and applications on a AD-APARD32690-SL platform board. The SPoE powered device (PD) and isolated flyback regulator provide 12 V power to the platform board. SPoE Class 10-12 (24 V nominal) and Class 13-14 (55 V nominal) are supported.

Designed for use on the AD-APARD32690-SL platform, the AD-APARDSPOE-SL hardware features Arduino Form-factor headers, and 3 pins to extract power from the AD-APARD32690-SL board.

To support board stacking and the development of field device applications using Arduino shields, the AD-APARDSPOE-SL is equipped with extra-tall headers, enabling other Arduino shields to be stacked on top of it.

The design also features a complete power isolation to the host AD-APARD32690-SL.

Figure 2 AD-APARDSPOE-SL Primary Side

The AD-APARDSPOE-SL uses 3 headers to connect to the AD-APARD32690-SL platform board to extract the SPoE power:

  • P5 is for the negative voltage rail.

  • P6 is for the positive voltage rail.

  • P7 is for the ground rail.

Power is supplied to the AD-APARD32690-SL platform board via PIN8 of the P1 header.

SPoE PD Power Class Selection (JP1 and JP2)

By default, the LTC9111 SPoE PD controller included in the AD-APARDSPOE-SL circuit is configured for PD Class 12. If a different PD class is required for the application, the JP1 and JP2 solder jumpers should be reconfigured to match the desired class.

Figure 6 Complete Evaluation Setup

To establish a 10BASE-T1L connection to an AD-APARD32690-SL using the AD-APARDSPOE-SL evaluation board and ping the AD-APARD32690-SL:

  1. Ensure that the jumpers and switches of the AD-APARDSPOE-SL are configured to the default settings.

  2. Connect the AD-APARDSPOE-SL circuit evaluation board to the AD-APARD32690-SL Arduino headers.

  3. Using a USB-C cable, connect P1 on the AD-T1LUSB2.0-EBZ evaluation board to a USB port on the computer.

  4. Operation with SPoE PSE:

    • Set the output of the PSE or DC power supply to either 24V (Class 12) or 55V (Class 14), depending on the settings of JP1 and JP2 on the AD-APARDSPOE-SL board.

    • Using a PROFIBUS cable, connect P1 on the AD-RPI-T1LPSE-SL evaluation board to P1 on the AD-APARD32690-SL evaluation board.

    • Using a PROFIBUS cable, connect P2 on the AD-RPI-T1LPSE-SL evaluation board to P2 on the AD-T1LUSB2.0-EBZ evaluation board.

  5. Upload the AD-APARD32690-SL TCP Echo Server Example to the AD-APARD32690-SL platform board using the MAX32625PICO programmer.

  6. By default the AD-APARD32690-SL has 192.168.97.40 as its IP address. If you are using a different IP address, make sure to update the AD-APARD32690-SL TCP Echo Server Example with the new IP address.

  7. Update the IP address of the Raspberry Pi’s Ethernet Interface depending on which port of the AD-RPI-T1LPSE-SL you are using (ETH1 / ETH2).

    Warning

    ADD STATIC IP FOR BOTH PORTS ETH1 192.168.97.10 ETH2 192.168.90.10

    Save the table and reboot the system by entering the following command in the console:

    analog@analog:~$

    sudo reboot

    • From the start menu open the Control Panel and click on Network and Internet

    • Click on View network status and tasks

    You should see two networks.

    Figure 7 Network Connections

    • Click on the Connections: Ethernet and click on Properties

    • Select Internet Protocol Version 4 (TCP/IPv4) and click on Properties

    • Select Use the following IP address: and type in the following IP address and Subnet mask:

      IP address: 192.168.90.zzz
Subnet mask: 255.255.0.0

      where zzz is a number between 1 and 254, currently unused in the network (for example, 10 cannot be used, since it is used by the AD-RPI-T1LPSE-SL).

    • Click on OK to save the changes and close the dialog boxes.

  8. Wait for the DS3 LED on the AD-APARD32690-SL evaluation board and the DS1 LED on the AD-RPI-T1LPSE-SL evaluation board to turn on and start blinking at the same time. This indicates that a 10BASE-T1L link has been established.

  9. Now you can ping the device to see if the connection is working properly. Open a terminal on your host PC connect to the AD-RPI-T1LPSE-SL through SSH:

    ssh analog@192.168.90.10

    Enter the password analog when prompted.

    You can now ping the AD-APARD32690-SL platform board using the following command:

    analog@analog:~$

    ping 192.168.97.50
