MOXA NPort 5250AI-M12-CT-T INTRODUCTION
The NPort 5000AI-M12 serial device servers are designed to instantly make serial devices network-ready and provide direct access to them from anywhere on the network. Moreover, they are compliant with EN 50121-4 and all mandatory sections of EN 50155, covering operating temperature, power input voltage, surge, ESD, and vibration. Thus, they are suitable for rolling stock and wayside applications where high levels of vibration exist in the operating environment.
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 email 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.
