Embedded Serial Servers

Embed a Device Server to Network Serial Based Hardware

Without an Ethernet port it's almost impossible to network older test, measurement, automation or point-of-sale equipment. The solution is an embedded serial server. An embedded serial server interfaces 10Base-T Ethernet with the RS-232 serial standard. Some products also handle RS4-22 and RS-485. It acts as a bi-directional translator between serial port-equipped devices and a modern Ethernet network. Data streams from the equipment are packetized and broadcast over a network or to a specific device like a PC. It also decodes data packets sent to the equipment over a network, converting them to a format and baud rate the equipment can accept.



Equipment designed for serial communication is found in industries from building access control to industrial automation and healthcare. Many retail point-of-sale systems incorporate a serial interface, as do building automation, data acquisition systems, and motion and process controllers.

Coupling this built-in serial port to an embedded serial server gives the equipment a unique IP address. Connected this way, it can send and receive data over an Ethernet network avoiding the need to replace older “legacy” equipment.

Product range

Antaria Technologies offers industrial-grade embedded serial servers ranging from the bare board LS100B to the board-mount NEMO10. Bare board devices come without an enclosure. They are intended for incorporation into existing equipment. On the serial side, there’s a male nine pin DB9 type connector and for Ethernet an RJ45 (phone style) socket.

When all that’s needed is cost-effective bi-directional communication between one RS-232 port and one Ethernet port the LS100B does the job. The maximum serial data speed is 115 kbps. TCP/IP protocols are fully supported enabling access over a LAN or broadband network.  Software for configuration and management over Telnet or the serial port is included.

Faster, more secure

Similar to the LS100B, the PS110B also handles RS-422 and RS-485 communication at speeds of up to 230 kbps.  It has features to simplify set up and use. Built-in Dynamic DNS protocol lets users access the connected serial device with its domain name. A Linux OS provides an easy-to-use configuration and management interface.  Security is addressed through features such as SSH, SSL, IP address filtering and HTTPS.

A programmable device server

The SS100B incorporates features such as flexible operation mode, TCP/UDP multicasting, telnet COM port control protocol support (RFC2217 compliant), SSL encryption, and port event handling. Security is provided through HTTPS, IP address filtering and SCP and RS-232, RS-422 or RS-485 serial-to-Ethernet connectivity is supported at speeds of up to 230 kbps.

Circuit board-mounted

The compact NEMO10 embedded device server mounts directly on a circuit board, embedding Ethernet connectivity directly into equipment like security systems, POS units, factory machinery, and medical devices. With speeds of up to 115 kbps, it supports 10Base-T Ethernet, ARP, IP/ICMP, TCP, Telnet, DHCP and PPPoE.

Don’t discard legacy equipment

Ethernet connectivity is essential in many businesses and industries, but achieving it needn’t mean discarding older equipment. Just add a serial device server and put it on a network.
