Moxa's NE-4100 embedded device servers are designed formanufacturers who want to add sophisticated network connectivityto their serial devices. Moxa's embedded device servers can be usedto convert any device with a standard serial interface to an Ethernet -enableddevice in no time. The NE-4100 embedded device servers support 10/100 Mbps Ethernet, and provide ready-to-use operationmodes, including TCP Server, TCP Client, and UDP. In addition, aReal COM driver is included for backward compatibility with legacysoftware.

SNMP and E-mail Alerts for Event Trap and Notification

NE-4100 embedded device servers can be configured to send an SNMP trap or e-mail under the following conditions:


  • Cold/warm start
  • Password authentication failure
  • Change in DSR/DCD line signal
  • Change in IP address
  • Change in password
