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:
LED1 | 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.
LED1 | LED 2 | LED 3 | LED 4 | Description |
Off | Blinking | On | On | No connection with the payments platform. |
3. The terminal has connected to our platform and now tries to board itself to your store.
LED1 | 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.
LED1 | 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.
Payment
The terminal has received a payment request and is ready for the shopper to tap their card or phone to the NFC-reader:
LED1 | LED 2 | LED 3 | LED 4 | Description |
On | Off | Off | Off | The CTLS logo also lights up |
LED1 | LED 2 | LED 3 | LED 4 | Description |
On | On | On | On | The buzzer also sounds |
Error
The terminal has failed to load its keys and needs to be replaced:
LED1 | 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.
Stop using the terminal and contact your support team immediately.
