+AD-APARDPFWD-SL
+================
+
+2-port 10BASE-T1L Arduino Shield with SPoE Power Forwarding
+"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+General Description
+-------------------
+
+.. figure:: apard-pfwd-top-iso.png
+   :width: 475 px
+   :align: right
+
+   AD-APARDPFWD-SL
+
+The :adi:`AD-APARDPFWD-SL <AD-APARDPFWD-SL>` is a 10BASE-T1L power forwarder
+with Single Pair Power over Ethernet (SPoE) for development of field devices and
+applications on a :adi:`AD-APARD32690-SL <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 :adi:`AD-APARD32690-SL <AD-APARD32690-SL>` platform,
+the :adi:`AD-APARDPFWD-SL <AD-APARDPFWD-SL>` hardware features Arduino Mega
+Form-factor headers, and two 10BASE-T1L ports for connecting to a
+10BASE-T1L Power Sourcing Equipment (PSE) such as the
+:adi:`AD-RPI-T1LPSE-SL <AD-RPI-T1LPSE-SL>` 2-port 10BASE-T1L w/SPoE PSE
+Development
+Platform.
+
+To allow board stacking and development of field device applications using
+Arduino shields, the :adi:`AD-APARDPFWD-SL <AD-APARDPFWD-SL>` has extra tall
+headers that allows other Arduino shields to be stacked on top of it.
+
+The design also features a complete power and data isolation to the host
+:adi:`AD-APARD32690-SL <AD-APARD32690-SL>`.
+
+Evaluation Board Hardware
+-------------------------
+
+Primary Side
+~~~~~~~~~~~~
+
+.. figure:: apard-pfwd-top-with-labels.png
+
+   AD-APARDPFWD-SL Primary Side
+
+The :adi:`AD-APARDPFWD-SL <AD-APARDPFWD-SL>` uses 2 10BASE-T1L ports. One port
+is the input port (**P7**), which supplies power to the
+:adi:`AD-APARD32690-SL <AD-APARD32690-SL>` platform board, and the other port
+is the output port (**P8**), which can be used to connect to another 10BASE-T1L
+device or to daisy chain multiple devices. The input port is connected to the
+:adi:`LTC9111` SPoE PD controller, which extracts the SPoE power from the
+10BASE-T1L cable and provides it to the :adi:`LT8304` isolated flyback
+regulator. The :adi:`LT8304` provides a regulated 12V.
+
+Power is supplied to the :adi:`AD-APARD32690-SL <AD-APARD32690-SL>` platform
+board via **PIN8** of the **P1** header.
+
+The onboard :adi:`ADIN2111` PHY provides the 10BASE-T1L connection to the host
+platform board. The :adi:`ADIN2111` is connected to the
+:adi:`AD-APARD32690-SL <AD-APARD32690-SL>` platform board via the **P5** and
+uses the SPI4 port of the :adi:`AD-APARD32690-SL <AD-APARD32690-SL>`.
+
+The :adi:`ADIN2111` supports selectable peak-to-peak transmit levels of 1.1V or
+2.4V for each PHY. To select the desired level, configure the P9 and P10 solder
+jumpers for PHY1 and PHY2, respectively:
+
+- Disconnected: Sets the transmit level to 2.4V
+- Shorted: Sets the transmit level to 1.1V
+
+The generic SPI protocol is half duplex. Therefore, it is not possible
+to write frame data into the MAC_TX register and read from the
+MAC_RX register at the same time. To achieve full duplex transmission on
+Ethernet at 10 Mbps, OPEN Alliance SPI must be used.
+To select which SPI protocol to use, the **JP3** solder jumper should be
+configured as follows:
+
+.. csv-table::
+   :file: ADIN2111_SPI_Selection.csv
+
+The :adi:`ADIN2111` supports software power-down after power-up / reset for each
+port independently. To utilize this feature:
+
+- Short jumper P11 to enable the software power-down for PHY1.
+- In order to enable the software power-down for PHY2, configure JP4 solder
+  jumper with the following settings
+
+.. csv-table::
+   :file: ADIN2111_Power_Down_Selection.csv

+
+SPoE PD Power Class Selection (JP1 and JP2)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+By default, the :adi:`LTC9111` SPoE PD
+controller included in the :adi:`AD-APARDPFWD-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.

+
+.. warning::
+
+   Do not use PD Classes 15!
+
+   The :adi:`AD-APARDPFWD-SL <AD-APARDPFWD-SL>` evaluation board is not
+   designed to handle the class 15's power specifications.

+
+   Complete Evaluation Setup
+
+To establish a 10BASE-T1L connection to an
+:adi:`AD-APARD32690-SL <AD-APARD32690-SL>` using the
+:adi:`AD-APARDPFWD-SL <AD-APARDPFWD-SL>` evaluation board
+and ping the :adi:`AD-APARD32690-SL <AD-APARD32690-SL>`:
+
+#. Ensure that the jumpers and switches of the
+   :adi:`AD-APARDPFWD-SL <AD-APARDPFWD-SL>` are configured to the default settings.
+
+#. Connect the :adi:`AD-APARDPFWD-SL <AD-APARDPFWD-SL>` circuit evaluation
+   board to the :adi:`AD-APARD32690-SL <AD-APARD32690-SL>` Arduino headers.
+
+#. Using a USB-C cable, connect **P1** on the
+   :adi:`AD-T1LUSB2.0-EBZ <ad-t1lusb20-ebz>` evaluation board to a USB port on
+   the computer.
+
+#. 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-APARDPFWD-SL board.
+   * Using a PROFIBUS cable, connect **P1** on the AD-RPI-T1LPSE-SL
+     evaluation board to **P7** on the
+     :adi:`AD-APARDPFWD-SL <AD-APARDPFWD-SL>` evaluation board.
+   * Using a PROFIBUS cable, connect **P2** on the AD-RPI-T1LPSE-SL
+     evaluation board to **P2** on the
+     :adi:`AD-T1LUSB2.0-EBZ <ad-t1lusb20-ebz>` evaluation board.
+
+#. Upload the :git-no-OS:`AD-APARD32690-SL ADIN2111 Example <projects/ASWPF/src/examples/adin2111_example/>`
+   to the :adi:`AD-APARD32690-SL <AD-APARD32690-SL>` platform board using the
+   :adi:`MAX32625PICO <MAX32625PICO>` programmer.
+
+#. By default the :adi:`AD-APARD32690-SL <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
+   :git-no-OS:`AD-APARD32690-SL ADIN2111 Example
+   <projects/ASWPF/src/examples/adin2111_example/>`
+   with the new IP address.
+
+#. Update the IP address of the Raspberry Pi's Ethernet Interface depending on
+   which port of the :adi:`AD-RPI-T1LPSE-SL <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:
+
+   .. shell::
+      :user: analog
+      :group: analog
+      :show-user:
+
+      $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:: ad-t1lusb2-network.png
+      :width: 400 px
+
+      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.
+
+#. Wait for the **DS1** LED on the
+   :adi:`AD-APARDPFWD-SL <AD-APARDPFWD-SL>` evaluation board and the **DS1**
+   LED on the :adi:`AD-RPI-T1LPSE-SL <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.
+
+#. 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 :adi:`AD-APARD32690-SL <AD-APARD32690-SL>` platform
+   board using the following command:
+
+   .. shell::
+      :user: analog
+      :group: analog
+      :show-user:
+
+      $ping 192.168.97.50
