Configuring the V400m payment terminal
Before you can begin processing payments, your V400m terminal must be fully set up. This section walks you through inserting the paper roll, turning on the terminal, and completing the boarding process.
Inserting the paper roll
The first step in preparing your terminal for use is loading the receipt paper. Follow the instructions below to insert the paper roll properly.
To insert the paper roll:
- Lift the paper compartment latch and open the cover.
- Insert the paper roll with the edge of the paper feeding from the top. Leave a small portion sticking out of the compartment.
- Close the compartment securely.
Powering on and boarding the terminal
After loading the paper, you can power on and board the V400m terminal. Ensure the terminal remains charged while you complete the onboarding process below.
To power on and board the terminal:
- Connect the power cable to the side of the terminal and plug the other end into a power source.
- If it doesn’t turn on automatically, press and hold the green circle button until the display turns on.
- Once powered on, tap Board terminal.
- When the screen displays your business information, tap Confirm.
When powered on for the first time or after a long period of inactivity, the terminal may run a 10–20 minute maintenance sync and update its software. The screen may also turn on and off a few times during this process.
Connecting the terminal to your Wi-Fi network
To pair your terminal with your Lightspeed Restaurant POS, start by connecting your terminal to the same Wi-Fi network as your POS register.
To connect the terminal to your Wi-Fi:
- Press the 9 key followed by the Confirm key (green circle) button on the terminal keypad.
- Enter the admin PIN: 5773.
- Tap Network > Wifi > Add network.
- Select your Wi-Fi network from the list.
- Use the number pad or the on-screen keyboard to enter your Wi-Fi password.
- (Optional) If using the number pad, press the key repeatedly to cycle through the letters until the desired letter is displayed.
- Press the Confirm (green circle) button.
- Press the red x button to return to the home screen with the Lightspeed logo.
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:
- Go to your POS.
- In the navigation menu, select Lightspeed Payments. A window will appear showing all terminals assigned to your site.
- (Optional) If you don't see your payment terminal, click Refresh terminal info at the bottom of the pop-up window.
- 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. - Click Pair.
- 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.
