Configuring the P400+ payment terminal 

Before using the P400+ terminal, it must be connected to power and your network via Ethernet or Wi-Fi. Ensure the terminal remains charged while you complete the onboarding process. 

To configure your payment terminal:

1. Slide the back cover up and remove it. 
2. Connect the adapter cable into the slot on the back of the terminal.
3. Slide the back cover on again.
4. Plug the power cable into the adapter cable's power port.
5. Plug the power cable into a power outlet.
6. (Optional) Connect an Ethernet cable to the port labeled ETH on the adapter cable. If connecting via Wi-Fi, follow the steps outlined here to connect. 

The terminal powers on automatically and stays on while plugged in. It does not have a power switch. 

Connecting the terminal to your Wi-Fi network

The P400+ payment terminal supports both Wi-Fi and Ethernet connections. If you don't have access to your router to set up a wired connection, you can connect the terminal to the same Wi-Fi network as your POS register. 

To connect the terminal to Wi-Fi:

1. The terminal will display Network Disconnected. Tap Connect.
2. Select Wi-Fi.
3. Tap the + icon to add a network.
4. Choose your Wi-Fi network from the list.
5. (Optional) Select Add manually to enter your SSID (network name) and password.
6. Use the number pad or the on-screen keyboard to enter your Wi-Fi password.
7. (Optional) If using the number pad, press the key on the number pad repeatedly to cycle through the letters until the desired letter is displayed. 
8. Tap the Check mark icon on the screen or press the green Circle button.
9. Press the red X button to return to the home screen. 

A Wi-Fi symbol should appear in the upper left corner of the screen, indicating an active connection.

Pairing the terminal with your POS

The next step is to pair your terminal with your POS. Each POS register can be paired with one payment terminal, but a terminal can be paired with multiple registers, allowing the POS registers to process payments through the same terminal.

To pair your terminal with the POS: 

1. Go to your POS.
2. In the navigation menu, select Lightspeed Payments. A window will appear showing all terminals assigned to your site.
   
3. (Optional) If you don't see your payment terminal, click Refresh terminal info at the bottom of the pop-up window. 
4. Find your payment terminal using the serial number.
   
   You can find the serial number on the back of the terminal below the barcode, or by pressing the 5 key followed by the green Circle button to access Device Info.
5. Click Pair.
   
6. Wait for the pairing process to complete successfully, then tap OK.
   

Once paired, process a transaction at checkout by selecting Lightspeed Payments to test the connection.
