1: Introduction
The Lantronix MSS family of Device Servers allows you to network-enable a variety of serial devices that
were not originally designed to be networked: personal computers, terminals, modems, industrial
machinery, and more. This capability brings the advantages of remote management and data accessibility
to thousands of serial devices.
The MSS4 offers a solution for almost every networking need. All MSS4 models provide four serial ports,
which are capable of RS-232, RS-422, and RS-485 communications, and a 10/100BASE-T Ethernet port.
In addition, certain models of the MSS4 include a 100BASE-FX fiber link Ethernet port and two PC card
slots. The slots can be used for 802.11 wireless Ethernet, flash storage, and modem cards.
Note:
For a current list of supported PC card technologies, please check the Lantronix Web
site, www.lantronix.com.
Parts of this manual assume knowledge of the IEEE 802.11 Standard governing wireless networking. If you
are not familiar with wireless networking concepts and implementation, please refer to the Standard or the
documentation that came with your wireless PC card.
Throughout this manual, the MSS4 may be referred to as the
MSS
or as the
Server
.
Model Overview
There are four MSS4 models, designated as -D, -S, -DFP, and -SFP. The models are differentiated by
whether or not they have a DB9 serial connector, screw terminal blocks, PC card slots, and fiber link
Ethernet.
MSS Features
TCP/IP and UNIX Compatibility
The MSS supports a variety of TCP/IP features, including Telnet, Rlogin, UDP, DNS, SNMP, WINS,
FTP, DHCP, BOOTP, RARP, and HTTP.
Connectivity
The MSS can connect serial devices directly to a 10/100BASE-T or 100BASE-FX wired Ethernet
network or an 802.11 wireless Ethernet network.
