Frequently Asked Questions

The PAX S920 and PAX A920 are advanced payment terminals within the PAX lineup, each tailored for specific functionalities. Although both are mobile terminals, they operate on different operating systems: the PAX S920 runs on the Linux-based Prolin OS, whereas the PAX A920 operates on Android. Additionally, the PAX A920 features a larger screen and both rear and front-facing cameras, whereas the S920 is camera-less. Both models include high-speed printers and lithium-ion batteries as standard features.

Follow these steps to connect your PAX S920 to WiFi:


  1. Make sure that your PAX S920 is turned on.  
  2. Press and hold the green button then select 1 to open Communication. 
  3. Enter your Password.
  4. Once the Password has been confirmed, select Main Comm. option from home screen.
  5. Navigate to WiFi, then scroll down to select the WiFi Parameters option.
  6. Choose your WiFi network of choice. Confirm the password. Following this, you should be connected to your local WiFi network.

There may be more than one option regarding the default password for your specific PAX S920 device. A few potential default passwords are:


  • 123456
  • 916860

The precise day and date of your WiFi installation (for example, if you were installing WiFi on your device on October 20th, 2024, your password would be 10202024).

In this context, PED is an acronym for Pin Entry Device. The PED handles sensitive cardholder data (including PIN numbers), among other functions crucial to your PAX S920. If you receive an error code indicating “PED tampered,” it suggests that your device may have been damaged or otherwise compromised. The issue could stem from something as straightforward as a depleted battery, though it is occasionally more serious. If you encounter this error code, refrain from solving the issue independently. Instead, contact PAX support or consider replacing your device.
