Setting up Vantiv Integrated Payments

Once you've received your terminals from Vantiv, you're ready to start setting up Vantiv Integrated Payments in Vend.

Important: You won't be able to complete the following steps until you've registered with Vantiv.

Create the payment type in Vend

2. Select 'Payment types'

3. Click the 'New Payment Type' button.

4. Choose 'Vantiv Integrated'

Set up each terminal

The following steps will need to be followed for each Dejavoo terminal you want to use. You can complete these steps on any computer, provided it's connected to the same network as the payment terminal.

Important: Each terminal can only be paired with one Register at a time.

Connect the Vantiv supplied terminal

1. Plug your terminal into your Internet router using an Ethernet cable (they need to be on the same network!)

2. Connect the terminal power

3. Turn the terminal on.

4. The screen should say 'POS Online.'

5. You will be asked to set the time on your payment terminal, please ensure this is correct as this will have an impact on the daily batch and settlement.

Connect the terminal to your Vend register

2. Click 'Configure your Vantiv Integrated account with Vend'.

3. A prompt will open stating 'Vantiv Integrated Payment would like access to your Vend Account'. Click the 'Allow Access' button.

4. Enter the serial number of the terminal you want to pair with this computer (It's on the back of the Dejavoo terminal.)

5. Hit 'Next'.

6. We'll send a test transaction for $0.01 to make sure the terminal is connected and working.

7. In Vend, select 'Yes' to accept, then on the terminal choose 'x' to cancel.

8. If you have more than one register, choose which register you'll be using this terminal with.

9. Hit 'Next'.

Connecting your Dejavoo terminal to your WiFi network (optional):

1. From the Terminal's Idle screen press the Enter/OK Key

2. Enter the Manager Password: 1234

3. Go to Utility then press Enter/OK

4. Enter the manager password again

7. Choose WIFI and pick the network you want to connect.

Note: The security protocol you need is WPA2

8. Next, go to Configure and set a password/passcode.

9. After entering passcode press the yellow key twice then go to Connect. Once it's connected press the Red or Yellow key until you are back on the POS > online or the Idle screen.

Reassign a terminal to a new register

If you want to use a terminal you've already connected with a different register, you'll need to reassign it.

1. Open the Setup page

2. Choose 'Payment Types'

The terminal displays 'POS Online' but does not light up when I attempt to pair it to a register

Please confirm the terminal and the Vend register are both on the same local network (they must be on the same subnet). You may also follow the steps above to Reassign a terminal and run through the pairing process again to make sure it was completed successfully.
