Moxa’s NE-4100 Series offers compact, embedded serial device servers designed for manufacturers who need fast and efficient Ethernet connectivity for their serial devices. With a footprint smaller than a credit card and a low power requirement of just 1.5 W, these modules are ideal for OEM applications where space and power are limited.

Supporting RS-232, RS-422, RS-485, and TTL interfaces, the NE-4100 Series operates in Real COM, TCP Server, TCP Client, and UDP modes. With SNMP traps and email alerts for monitoring system events, and broad compatibility with many operating systems, these modules are industrial-grade solutions for modern network integration needs.
