Understanding possible issues with a Nayax Onyx on an Arcade Machine
The most common issue is an M02 error code. When displayed it means that the Nayax has experienced a problem while trying to connect to a mobile network signal and/or in some cases has failed to get a local network signal (LAN connection).
The Nayax reader should still respond to user requests at this point. Push the menu button on the front of the Nayax unit, as indicated by 3 lines. You should be presented with a screen with a few options. look for the top left button here, marked 'Terminal Info' and push it.
The screen should change to show information regarding the mobile service it is receiving. Like on modern smartphones there is a signal strength indicator and below it an 'RSSI' reading.
Understanding the RSSI Reading
The RSSI is reported as a number and scales between 0 and 99. Strange as it might seem, the lower the number the better the mobile service the Nayax Onyx is receiving. These readers can in fact connect to any mobile network service and will pick the strongest signal it can find at start-up.
For everyday reliable operation is it best to have an RSSI that is under 20. In fact even to about 34 that service should work, but might be slower to respond.
Anything above this figure will normally mean there is not really a good enough or reliable enough signal for the Nayax Onyx to operate fully. This is likely to lead to periods of no service, as the the Mobile Signal fluctuates.
Fault Resolutions for Nayax Onyx on an Arcade Machine
In most cases this is reliant upon the Mobile Network Signal returning to a usable level and hopefully the Nayax Onyx will start to operate normally again.
Effectively there is little else an operator can do. Relocating the machine, or moving the aerial location, to try and help secure a better signal.
However, the best solution for problematic signal service is to connect the Nayax Reader to a Local Area Network Service (LAN).
This is a job for our service team working in partnership with the venue to secure such a LAN service and re-fit the Nayax Onyx with new cables.
Nayax Connected to a Network (LAN)
In some cases the Nayax Onyx might be connected to your local network or Wifi service. In this case using the terminal Info button will show the status of that network connection.
If the network is connected correctly then the screen should show a LAN IP address and the Gateway IP address. If either of these are missing/blank then there is a network issue which we will need to review.
Even with a faulty LAN connection the Nayax will try and 'fallback' to a mobile network connection. However, if the Nayax is using LAN then it is likely that the mobile network, in your venue, is not strong enough to work properly.
IMPORTANT: It is also possible that the Nayax might be 'Out of Order' even with good LAN and Gateway IP addresses. In this case the most likely problem is that your internal network is currently experiencing issues with access to the internet.
