Sample script with description how to set up FTP, NTP, and the name of saved images with the current date
Purpose
This script is intended for use in applications where it is necessary to add a timestamp to scanned results or images saved via FTP.
Hardware
This script is designed to work with fixed-mount readers and has been tested on the DataMan 470 series.
Hardware List:
The system requires access to the NTP server to synchronize the internal clock. If access is not provided, the system will operate on the default date and time.
To set up the NTP server on the reader, navigate to the Settings tab.
You will need to fill in the required fields, including the time zone. Optionally, you can enter the NTP server address for date/time synchronization.
Once the data is entered, save all settings and reboot the device.
Scripting should be enabled under the Format Data tab.
Both scripts should be uploaded to their respective tabs (Data Formatting and FTP Storage).
To set up FTP storage for images, go to the Buffering and Transfer settings.
