UX410 user manual

Learn how to set up and use the UX410 unattended payment terminal.

The UX410 payment terminal allows shoppers to pay with a contactless card or a mobile wallet by tapping their card or phone on or near the NFC-reader. Instead of a display, this terminal has indicator LEDs, an illuminating contactless logo, and a dual-tone buzzer to indicate the progress of the payment and other events.

The UX410 payment terminal consists of two separate devices:

  • UX410 NFC-reader (also called antenna unit)
  • UX410 controller unit

These devices are intended for mounting in a self-service machine such as a vending machine, coffee machine, token dispenser, or parking payment system.

Get started

Get your new unattended terminal up and running:

  1. Assign the terminal to your store.
  2. Inspect the terminal.
  3. Install the terminal.
  4. Monitor the boarding process.

When LED 4* is blinking slowly, you are ready to process payments!

* The four LEDs are above the contactless logo. LED 4 is to the right of the logo.

Supplied components

  • UX410 NFC-reader
  • UX410 Controller unit
  • Clamping plate and four M4 washers and nuts to secure the reader
  • RJ45 communication cable
  • SMA (RF) antenna cable
  • Power cord/adapter


Component Device dimensions Cutout dimensions
UX410 NFC-reader Height 80mm x Width 80 mm x Depth 16mm Height 61.2mm x Width 73.2mm
UX410 controller Height 90mm x Width 100mm x Depth 34mm (none)

For the NFC-reader, the front of the self-service machine needs to have an installation panel of about 2mm thick with a cutout and 4 mounting holes.

Assign the terminal

During the installation, the UX410 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.

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 terminal serial number (S/N) on the box is the same as in the Customer Area. This refers to the serial number of the controller unit, and it is listed on the box two times.
    • 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 NFC-reader and the controller unit out of the box, and verify that the part numbers (P/N) and serial numbers (S/N) on the devices are the same as the numbers 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 such as the card reader or ports.
If any of the above checks fails, contact our POS Support Team immediately.

Install the terminal

Apart from the supplied components, you will need at least:

  • 8 bolts, washers, and nuts to secure the clamping plate and the controller unit inside your self-service machine.
  • Installation instructions form the manufacturer of your self-service machine.

Proceed as follows:

  1. Mount the NFC-reader to the front of the installation panel.

    1. Remove the protective film from the back of the NFC-reader.
    2. Place the stud bolts of the NFC-reader through the holes in the front of the installation panel.
    3. At the back of the installation panel, place the flat side of the clamping plate over the stud bolts.
    4. Secure the NFC-reader using the four supplied M4 washers and nuts to a torque of 0.7 Nm.
    5. Secure the clamping plate to the installation panel.
    6. Remove the protective film from the front of the NFC-reader.

  2. Secure the controller unit inside the self-service machine near the NFC reader, using 4 bolts, washers, and nuts to a torque of 0.7 Nm.

    Do not install the controller unit inside a chassis that can be removed from the self-service machine.

  3. Connect the NFC reader to the controller unit.

    1. Connect the SMA (RF) cable to the back of the NFC-reader and to the RF port on the bottom of the control unit.
    2. Connect the RJ45 cable to the back of the NFC-reader and to the COMM port on the bottom of the control unit. Don't use the COM1 port.

      The RF port and the COMM port are located next to each other on the bottom of the control unit, and are marked ANT.

  4. Connect an Ethernet cable between the LAN port on the controller unit and your network.

    Only connect a regular Ethernet cable to the LAN port. Using any other type of cable or another port, such as the COM1 RS232 port, might severely damage the device.

  5. Connect the power cord between the DC IN port on the controller unit and a power supply unit in the self-service machine or an external power source.

The controller beeps. After approximately a minute, a green light and an amber light on the LAN port turn on. The terminal starts boarding.

Monitor the boarding process

When you finish the installation, the UX terminal starts up, connects to the network, and boards itself to your store. The LEDs indicate the steps in this process.

The steps may go too fast to follow. But if an issue occurs, the LEDs indicate the step where the process has stopped:

  1. The terminal tries to connect to your network:

    LED 1 LED 2 LED 3 LED 4 Description
    Blinking On On On No network
  2. The terminal has connected to your network and now tries to connect to our platform:

    LED 1 LED 2 LED 3 LED 4 Description
    Off Blinking On On No connection with the Adyen payments platform
  3. The terminal has connected to our platform and now tries to board itself to your store:

    LED 1 LED 2 LED 3 LED 4 Description
    Off Off Blinking On Not boarded

    The terminal will stay in this state if it hasn't been assigned to a store (or merchant account representing a store).

  4. The terminal has boarded and is ready to accept payments:

    LED 1 LED 2 LED 3 LED 4 Description
    Off Off Off Blinking slowly Ready

If boarding doesn't succeed, the terminal will try again after two minutes. Remember that the terminal can only board if it is assigned to your store.
After ten retries, the terminal stops trying to board. You can't tell it has stopped trying; LED 3 continues to blink and LED 4 remains on. You can trigger the boarding process again by disconnecting the controller unit from the power source, and then connecting it again.

Other LED signals

During the boarding process, the LEDs indicate the progress. There are various other events and situations that are also indicated with LED signals. We describe a few of them here.


The terminal has received a payment request and is ready for the shopper to tap their card or phone to the NFC-reader:

LED 1 LED 2 LED 3 LED 4 Description
On Off Off Off The CTLS logo also lights up

The shopper has tapped their card or phone and the NFC-reader has read the card details:

LED 1 LED 2 LED 3 LED 4 Description
On On On On The buzzer also sounds


The terminal has failed to load its keys and needs to be replaced:

LED 1 LED 2 LED 3 LED 4 Description
Off Off On On Keys not loaded

Red light

A red LED 1 indicates a warning. The terminal may have been tampered with.
