Connect the P400 plus to your network

Connect your terminal to the internet so that it can communicate with the Adyen payments platform and your own back end systems.

Connect the P400 plus to your wired network

  • Connect your Ethernet cable to the ETH port on the dongle.

Only connect a regular Ethernet cable to the ETH port. Using any other type of cable or another port (for example, the RS232 port) might severely damage the device.

Connect the P400 plus to your wireless network

If the terminal is not yet boarded:

  1. Press the Configure Network button on the display.

    This button is only available when the P400 is not connected with an Ethernet cable

  2. Press 3. Wifi.
  3. Press 1. Turn on Wi-Fi to make sure the Wi-Fi is turned on.
  4. The terminal will begin scanning for Wi-Fi networks.
  5. Choose the desired network and enter the wireless password.
  6. The terminal sets the network as default automatically, and connects to it.
  7. Exit the network menu to begin boarding the device.

If the terminal is boarded:

  1. Press 9 and then press  to open the Admin menu. 
  2. Enter your Admin PIN code. If you don't know this code, see our POS Troubleshooting section.
    The terminal displays the Admin menu.
  3. Press 1. Network.
  4. Press 3. Wifi.
  5. Press 3. Scan networks.
  6. Tap the name of the network and enter the password.
  7. The terminal sets the network as default automatically, and connects to it.

(Optional) Configure a static IP address

By default, DHCP is enabled on the payment terminal. With this setting, your DHCP server assigns an IP address to the terminal.
If you are not able to use a DHCP server, you need to disable DHCP and define a static IP address for the terminal:

  1. On a connected terminal, open the Admin menu:

    1. Press 9 and then the Confirm button. (On some models, it is Confirm and then 9.)
    2. Enter the PIN code for the Admin menu and press the Confirm button.
      Where do I find the Admin PIN?

  2. Select Network and then, depending on your connection type:

    Connection type Select
    Wired Ethernet.
    Wireless WiFi > select your Wi-Fi network > IP Settings.
    Bluetooth Bluetooth > IP Settings.
  3. In IP Settings, clear the Use DHCP check box.
  4. Enter your network details. To type a period (.), press 1 twice. Enter the IP address, the Subnet mask, the Default gateway, the Preferred DNS, and the Alternate DNS.

    The static IP address must be unique in the network and, if you have more than one terminal, unique for each terminal.

  5. Select Apply.
