NPort 5450AI-M12 overview


The NPort 5000AI-M12 serial device servers are designed to make serial devices network-ready in an instant, and provides direct access to serial devices from anywhere on the network. Moreover, the NPort 5000AI-M12 is compliant with EN 50121-4 and essential sections of EN 50155, covering operating temperature, power input voltage, surge, ESD, and vibration,  making them suitable for rolling stock and wayside applications where high levels of vibration exist in the operating environment.

The NPort 5000AI-M12’s 3-step web-based configuration tool is straightforward and user-friendly. The NPort 5000AI-M12’s web console guides users through 3 simple configuration steps that are necessary to activate the serial-to-Ethernet application. With this speedy 3-step web-based configuration, a user only needs to spend an average of 30 seconds to complete the NPort settings and enable the application, saving a great amount of time and effort.

NPort 5000AI-M12 device servers support SNMP, which can be used to monitor all units over Ethernet. Each unit can be configured to send trap messages automatically to the SNMP manager when user-defined errors are encountered. For users who do not use SNMP manager, an e-mail alert can be sent instead. Users can define the trigger for the alerts using Moxa’s Windows utility, or the web console. For example, alerts can be triggered by a warm start, a cold start, or a password change.
