How to enble NTP server on Windows System to sync the time with Robustel device in a private network?
Overview
The customer's factory operates on a pure internal network. Our R5020Lite gateway is required to collect data and transmit it to the factory's server database (Windows Server) for storage. Simultaneously, as the database has an MQTT program enabled, time synchronization with the gateway is necessary for proper communication.
