NCR Self-Checkout Scale: Troubleshooting Incorrect... | terminalfaults.org

Technical Background:

The self-checkout scale relies on a real-time clock (RTC) chip powered by a small battery or supercapacitor. The system attempts to synchronize with an external time server via network connection (NTP). Fluctuations in mains power, network latency, and battery degradation affect time accuracy. Serial communication issues on the internal bus can also disrupt accurate time updates.

Symptoms:

The NCR self-checkout scale displays an incorrect date and/or time.

Possible Causes:

Weak or depleted RTC battery/supercapacitor preventing the scale from maintaining the correct time when power is off or during power dips.
Network connectivity issues preventing the scale from synchronizing with a Network Time Protocol (NTP) server.
Incorrect NTP server configuration within the scale's software settings.
Power fluctuations or surges affecting the RTC chip's operation.
Software bugs or glitches causing time synchronization failures.
Damaged or loose network cable leading to intermittent connectivity.

Solution:

1

Verify the network cable is securely connected to both the scale and the network switch/router.
2

Check the scale's network configuration to ensure it has a valid IP address, subnet mask, gateway, and DNS server.
3

Confirm that the scale is configured to use a valid and reliable NTP server. The default NCR server or a public server like pool.ntp.org can be used.
4

Perform a software reset of the scale through the operator menu (refer to NCR documentation for specific steps).
5

Check the scale's system logs for any error messages related to time synchronization or network connectivity.
6

Ensure that the scale's software is up to date. Outdated software may contain bugs that affect time synchronization.
7

As a temporary workaround, manually set the correct date and time through the operator menu.

Safety Warning:

Safe Handling: Always unplug the scale from the power outlet before inspecting or adjusting any cables. Avoid contact with internal components. Ensure the area around the scale is dry and free of obstructions. The scale contains electronic components sensitive to electrostatic discharge (ESD). Avoid touching connectors without proper ESD grounding.

Prevention:

To prevent future date/time issues, ensure a stable power supply to the self-checkout scale. Use a UPS (Uninterruptible Power Supply) to protect against power outages and surges. Regularly inspect network cables for damage and ensure they are securely connected. Periodically check the scale's time synchronization settings and ensure they are correctly configured.

Expert Tip:

If the time is consistently off by the same amount, this could indicate an incorrect timezone setting in the scale's configuration. Verify the timezone setting and adjust if necessary. A failing RTC battery *may* present as intermittent network connection failures when the system struggles to boot.

Frequently Asked Questions

•How do I access the operator menu on the NCR self-checkout scale?

Refer to the NCR documentation for the specific key combination or procedure to access the operator menu. It typically involves pressing a sequence of buttons on the touchscreen or keypad.

•What are the default network settings for the NCR self-checkout scale?

The default network settings vary depending on the model and configuration. Consult the NCR documentation or contact NCR support for the specific default settings for your scale.

•How often should the RTC battery be replaced?

The RTC battery typically lasts for 3-5 years. Replace it when the scale consistently loses time even after network synchronization.
