Hi. How can we help?

Setting up the Verifone P400+ with Lightspeed Payments

The Verifone P400+ terminal is quick and easy to set up with Lightspeed Payments. When you receive the terminal from Lightspeed, it will already be configured for your account, so all you will need to do is plug in and pair the terminal.

It is important that you only use the terminal supplied to you by Lightspeed, as any terminal obtained from a third party may not be correctly configured for your account and could present a security risk.

In the box

When you receive your payment terminal, the box will contain:

  • 1 power cable
  • 1 Verifone P400+ terminal
  • 1 adapter cable
  • 1 ethernet cable

Physical setup

To set up the terminal:

  1. Open the back of the terminal by sliding the tab up and pulling away.
  2. Plug the adapter cable into the back of the terminal.
  3. Replace the tab.
  4. Plug the power cable into the electrical port on the adapter cable.
  5. Plug your ethernet cable into the port on the adapter cable labeled ETH.
    Note: Only a wired internet connection is supported for the P400+ at this time
  6. Plug the other end of the power cable into a power source.

The terminal will boot up immediately - there is no power switch. If the terminal is plugged in, it is on.

Pairing the terminal

Once the terminal has finished booting, you'll need to pair it with your account.

  • To pair your terminal:

    1. Navigate to Settings >Payment Processing.
    2. Click + Add Terminal.
    3. Enter a descriptive name for the terminal.
    4. Use the drop-down menu to select the terminal model: Verifone P400 Plus.
    5. On the terminal's number pad, enter 07139. This will display an activation code.
    6. Enter the three-word activation code exactly as it appears on the terminal's screen (including the hyphens).
    7. Click Add.
    8. The terminal will return to the default screen and you are now ready to accept card payments.
    9. (Optional) Confirm the connection between Lightspeed Retail and your payment terminal by clicking Test connection.

    Disconnecting the terminal

    If you ever need to disconnect the terminal from your account, you can do so from the Payment Processing screen.

    1. Navigate to Settings > Payment Processing.
    2. Click the delete terminal button next to the name of the terminal you wish to unpair.

    7. Tap Done.
    8. The app will confirm that the payment terminal has been successfully paired. Tap Done.
    9. The terminal's name and status will be displayed. Tap Done.

    The terminal's name and status will now be visible on the profile screen.

    Disconnecting the terminal

    If you ever need to disconnect the terminal from your account, you can do so.

    1. Tap the payment terminal on the profile screen.
    2. Tap the information button next to the terminal's name.

Resolving problems with your P400+

If you're experiencing trouble with your P400+ payment terminal, there are a few things you can check on your own to help you resolve the issue. Before anything else, there are certain conditions that are required for the P400+ to operate, and you should verify that these conditions are met.

  • Navigate to Settings > Locations, click Customize beside the correct location, then click Credit Card and verify that Lightspeed Payments is set as the payment gateway.
  • Navigate to Settings > Payment Processing, and verify that the terminal is displayed with the paired status.
  • If you have multiple P400+ terminals, verify that the correct terminal is selected before starting the payment.
  • If you have multiple networks, verify that both the P400+ terminal and your computer or iPad are connected to the same network.
  • For some users, a recent software update has caused the P400+ payment terminal to frequently disconnect from the Retail POS iPad app. While we work to resolve the issue, you can resolve your terminal's connection instability by unpairing the terminal through the Manager interface, then re-pairing the terminal through the POS interface. You can find detailed instructions here.

  • Unplugging the terminal from its power source and plugging it back in will reset the terminal. This will resolve the problem most of the time. The terminal may update when restarted. Note that the update should never take more than 15 minutes. If it does, the terminal may have lost its connection to the internet during the update, or may be frozen again. Try unplugging the terminal and plugging it back in again to resolve this.

  • To verify that the terminal is able to connect to the internet, enter 0-8-6-2-4 on the pin pad. The terminal will run a network probe, after which the screen should display:

    OK: Armada
    OK Stripe

    After noting the results of the test, press the 0 (zero) key to exit the test.

    If the OK messages above do not display, it means the terminal is not connected to the internet. After verifying that the ethernet cable is still securely connected, you can check your computer’s firewall/blacklist settings or your router settings to try to find the source of the problem.

  • Useful information about the terminal's firmware version and network can be obtained by checking the device status. Doing so and taking a picture of the results can help our Support team diagnose any issues you were not able to resolve on your own.

    To check the device status, enter 0-4-2-6-8 on the pin pad. The screen should display:
    • P400 Plus IP address (defaults to DHCP)
    • Account ID
    • Device software version
    • Location
    • Network gateway, DNS
    • Network mask
    • a MAC address, or WLAN network name

    After you've taken a picture of the results, press the 0 (zero) key to exit the test.
