Get started

Get your new unattended terminal up and running:

1. Assign the terminal to your store.
2. Inspect the terminal.
3. Set up the S1U2 terminal:
   1. Mount the terminal in the front panel of the kiosk or self-service machine.
   2. Connect the cables.
   3. Board the terminal.
   4. Update the terminal software.
4. Do any remaining steps related to mounting the terminal.

When you've completed these steps, you're ready to process payments!

Assign the terminal

During the installation, the S1U2 terminal obtains its configuration by boarding itself to your store. Contrary to most other terminals, you always need to assign an unattended terminal to a store before boarding the terminal.

• Assign the terminal to your store using your Customer Area or using API calls.

Inspect the terminal

Because payment terminals process sensitive card data, you must verify that the terminal you received is the correct one, supplied by Adyen, and hasn't been tampered with.

1. Verify that the box containing the terminal hasn't been opened and that the security seal is intact.
   The security seal is a red label with a bar code and a number, stuck across the lid of the box.

2. If you have access to the Adyen Customer Area, log in and under Point of sale > Orders and returns find the order for your terminal. Then:

   • Verify that the serial number (S/N) on the box is the same as in the Customer Area.
   • Verify that the security seal number on the box is the same as in the Customer Area.

   • Using the track & trace link, track the order with the carrier to verify that they confirm having delivered the payment terminal.

3. Break the security seal, take the terminal out of the box, and verify that the serial number (S/N) on the terminal is the same as the serial number on the box.

4. Inspect the terminal for tampering. Check for missing seals or screws, additional wires or labels, holes in the device, and anything inserted in or attached to any part of the terminal.

Mount the terminal

You need to mount the S1U2 payment terminal on your vending, ticketing, multimedia kiosk, or other self-service solutions. To learn how to mount S1U2, see:

• The installation instructions from the manufacturer of your self-service machine.
• The installation instructions from Castles, the manufacturer of the S1U2 payment terminals.

Connect the cables

1. Connect the MDB harness cable to the back of the terminal. This cable connects the terminal to the Ethernet cable, the power supply, and optionally to the audio output device.

   You can also connect the Ethernet cable directly into the terminal between the MDB slot and the SIM/SAM card slots.

2. Connect the cellular communication antenna cable to the top antenna slot. To boost the signal, you can also connect two antennas.
3. If your use case requires it, connect your self-service device to the S1U2 using the USB-A or USB-C slots on the back.

The S1U2 terminal now starts up.

Connect to your network

Connect your terminal to the internet so that it can communicate with the Adyen payments platform and your own back-end systems.

Connect to Wi-Fi

1. After selecting your language on the Welcome screen, select the arrow button:
   
2. On the Setup Wi-Fi screen, select the + sign.
3. Turn on the WLAN toggle switch.
4. Select a Wi-Fi network from the list, or select the + sign and add the name (SSID) of the Wi-Fi network.
5. Enter the Wi-Fi password.
6. Select OK.
   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.

Updating the connection settings

If you need to change Wi-Fi usage later:

1. Select Settings > Network.
2. Enter your passcode.
3. Select Wi-Fi. You can now:
   • Turn Wi-Fi on or off using the WLAN toggle switch.
   • Add another network as described above.

Cellular 3G/4G failover

Your S1U2 terminal can automatically switch to processing payments using a cellular connection when the internet connection fails. For this you need to have a SIM card subscription with us for the terminal. When in doubt, contact our POS Support Team.

Board the terminal

Remember that the terminal can only board if it is assigned to your store.

1. When the display shows Board the terminal, on the screen press OK.
2. When the display shows the store that the terminal is assigned to, press OK to confirm.

Update the terminal software

1. Under Settings, select Device info > Software version.
2. Enter the Admin & Settings passcode and select Continue.
3. Select Install now.

When the terminal finishes downloading and installing the software, it reboots. After that, you're ready to accept payments.
