Dejavoo Z11 PIN pad troubleshooting. Diagnose communication errors, cable faults, and electrostatic discharge issues. Follow our professional repair steps.
A lit display suggests power is present, but the keypad controller might be faulty or the communication link is down.
Power surges can damage electronic components. Consider using a surge protector.
Physical shock can damage internal connections or components.
Electrostatic Discharge (ESD) can damage the PIN pad's internal components. Avoid touching the connector pins. Ensure hands are discharged before handling the device. Do not use excessive force when connecting or disconnecting cables. Never open the PIN pad enclosure due to PCI-PTS security requirements and tamper-evident features. This will void the warranty and render the device unusable.
Minimize cable strain by ensuring sufficient slack in the communication cable and avoiding sharp bends.,Regularly clean the PIN pad surface with a dry, lint-free cloth to prevent the buildup of dust and grime.,Implement ESD prevention measures, such as using anti-static mats and wrist straps, especially during dry winter months.,Periodically inspect the communication cable and connectors for damage or corrosion.
Try a different USB port on the main terminal. Some USB ports may provide insufficient power or have driver conflicts. If the Z11 uses a separate power adapter, ensure it is the correct voltage and amperage specified by Dejavoo.
