Follow these steps to setup your P400 Plus terminal
When you have completed these steps, you are ready to process payments! ✅
Setup P400 Plus terminal
Open the cover on the back of the terminal, connect the dongle cable, and close the cover.
Tighten the cam lock screw on the back cover (if present), to help prevent damage to the cable connector caused by pulling the cable.Turn on the terminal by connecting it to a power source. During startup the display turns on and off a few times.
Configuring network
Connect your terminal to the internet so that it can communicate with the Adyen payments platform. Follow the instructions for the network connection you want to use: Ethernet LAN or Wi-Fi.
Connecting to Wi-fi
Press 9 and then the green button below
On the terminal display, select Configure network
Enter PIN code: 7705
Turn on the Wi-Fi toggle switch
Select the + icon to add a network. The terminal scans for Wi-Fi networks
Choose the desired network from the list and enter the Wi-Fi password, or select Add manually and enter the name (SSID) of the Wi-Fi network and the Wi-Fi password
Select the check mark to confirm. The terminal sets the network as default automatically, and connects to it. You'll now see a Wi-Fi icon at the top of the display
Connecting to Ethernet
Connect an Ethernet cable to the Ethernet (LAN) port on the dongle.
That is the port marked with ETH.
Connecting the Ethernet cable to the wrong port (the RS232 port) may severely damage the terminal
Test the payments platform connection
Payments are processed on the Adyen payments platform. To test the connection with that platform:
Select Settings > Diagnostics > PSP connection.
Check if the Status is Successful. If the display says Failure the terminal is not connected
