Moxa’s NE-4100 embedded device servers are designed for manufacturers who want to add sophisticated network connectivity to their serial devices. Moxa’s embedded device servers can be used to convert any device with a standard serial interface to an Ethernet-enabled device in no time. The NE-4100 embedded device servers support 10/100 Mbps Ethernet, and provide ready-to-use operation modes, including TCP Server, TCP Client, and UDP. In addition, a Real COM driver is included for backward compatibility with legacy software.

SNMP and Email Alerts for Event Trap and Notification
NE-4100 embedded device servers can be configured to send an SNMP trap or email under the following conditions:

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