Make Serial Devices Ready to the Network
The Industrial Serial Server SE5404D is a 4-port gateway between Ethernet (TCP/IP) and serial signal communications. It allows almost any serial device to be connected to a new or existing Ethernet network. By encapsulating serial data and transporting it over to Ethernet, SE5404D offers full-duplex, bi-directional data transmission transparent between serial port and
Ethernet network.

Easy to Use
Flexible configuration options enable this unit to be setup over Ethernet by Telnet, Web browser, Serial Console, or other utilities. Packed in a rugged metal housing for DIN rail or wall mount with 9~48VDC wide power input range, SE5404D is ideal for almost any industrial and manufacturing automation. Atop Virtual COM software provides existing Windows based
applications to access a serial device by mapping to a remote serial server via Ethernet.

Specially Designed for Automation Fields
In industrial and manufacturing automation fields, SE5404D is used as a field d e v ice t o connect Ethernet through TCP/IP protocol directly. It is also specially designed for conjunction with PLCs, HMIs, Barcode Scanners, Data Terminals, Electronic Kanbans , Shop Floor Control Systems, and Pick-to-Light Systems.
