Q3: The PAX S300 pin pad is not working properly or shows a black screen. How do I fix it?

If the screen is completely black, then the pin pad is not getting any power. Make sure the power cable is attached and the power socket is good. Some pin pads use a smart power plug for remote power control. If the smart plug is turned off, the power socket will not work. Either power on the smart plug or move the power cable to a working socket.

Pin pads can malfunction when they are powered on for a long time. We recommend a reboot at least once a week. Unfortunately, PAX S300 pin pads can only be rebooted by performing a power cycle. Here’s how to power cycle a PAX S300 pin pad:

  1. Follow the thick black cable of the pin pad to the fan-out hub (about 2 feet away).

  2. At the fan-out hub, disconnect the small black power cable (the L shaped barrel connector labelled PWR in this diagram).

  3. Make sure the right pin pad is turned off; should be completely black.

  4. Wait for 10 seconds (very important).

  5. Then, plug the power connector back in.
