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 .
1.1 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 Introduction
1- 2
1.2 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.
◆
Ease of Use
The MSS4 has a simple but powerful command interface for both users and system
managers. The MSS Local mode supports command line editing and command line
recall. An extensive Help facility is included.
The EZWebCon utility (provided on the CD-ROM) allows you to configure the
MSS from any host machine running the Java Virtual Machine (JVM). It also allows
remote host logins into the MSS, which are similar to Telnet logins.
The Lantronix ThinWeb Manager, a set of HTML pages stored on the MSS, allows
youto configureserver informationvia aJavaScript-enabled webbrowser. Formore
information, see Web Browser Login and Configuration on page 3-6.
◆
Remote Configuration
The MSS can be logged into and remotely configured via a network login, a Telnet
login to the remote console port, EZWebCon, or a web browser connection to the
MSS’s internal HTTP server.
◆
Context-Sensitive Help
Context-sensitive on-line help is available at any time. You may type Help by itself
for overall help, Help <command> for help on a specific command, or a partial
command line followed by a question mark for help on what is appropriate at that
particular point.
Note:
See the MSS Reference Manual for more information.
◆
Reloadable Operating Software
The MSS stores its operating code in Flash ROM, which means that it does not have
to download code at boot time. If necessary, you can upgrade the MSS’s operating
code to support additional features as newer code becomes available. Also, you can
configure the MSS to request a downloaded configuration file at boot time.

Introduction TCP/IP Support
1- 3
◆
Security
The MSS includes several configurable security features:
❍
Automatic session logouts when a port is disconnected or a device is turned off.
❍
Password protection for privileges, ports, services, maintenance commands,
and the remote console.
❍
An IP security table, which allows the MSS manager to restrict incoming and
outgoing TCP/IP connections to certain ports and hosts. This allows managers
to restrict MSS access to a particular local network segment or host.
◆
Diagnostics
Power-up and interactive diagnostics help system managers troubleshoot network
and serial line problems.
◆
SDK Support
TheMSS supports theLantronixSoftware Developer Kit(SDK), which allowsusers
to customize the MSS and add functionality. For more information about the SDK,
please contact Lantronix directly.
Note:
The SDK does not allow users to configure custom PC card support.
1.3 TCP/IP Support
The MSS supports the TCP/IP network protocol. A network protocol is a method of
communicating over Ethernet. The protocol specifies a certain arrangement of data in the
Ethernet packets, and provides different services for its users.
TCP/IP support includes Telnet, Rlogin, UDP, DNS, and WINS. The Telnet terminal
protocol is an easy-to-use interface that creates terminal connections to any network host
supporting Telnet. Rlogin is a protocol that allows users to initiate a TCP/IP login session.
UDP (User Datagram Protocol) is a connectionless protocol that results in smaller packet
headers, no session overhead, and the ability to send to multiple hosts. The MSS also
supports the use of Domain Name Servers (DNS), allowing a network nameserver to
translate text node names into numeric IP addresses. For WINS support, the MSS can be
configured to announce itself as a WINS node.
The MSS also implements basic Simple Network Management Protocol (SNMP)
functionality. SNMP commands enable users, usually system administrators, to get
information from and control other nodes on a local area network (LAN), and respond to
queries from other network hosts. The MSS allows configuration of one community name
with read/write access. Instructions for SNMP configuration are available in the SNMP
section of this guide, page 4-5.

2.2 Installing in a Wired Network
The MSS should be positioned close to the device it will be servicing. Since powering
down the unit will terminate any active sessions, it may be desirable to place the server in
a location secure from user access. Also be aware of the unit’s environmental operating
limits and cabling requirements. See Appendix C and Appendix E for details.
The following diagram shows a properly-installed MSS in a wired Ethernet network. The
numbers in the diagram refer to the installation steps in this section.
Figure 2-4: MSS Connected to Serial Device and Network
1Connect the MSS to a serial device. Note that all serial ports are initially configured
for RS-232 networking.
AConnect one end of a serial cable to either one of the MSS DB9 connectors or
screw terminal blocks (depending on the model). See Appendix C for MSS
connector pinout information.
Note: For the first connection, you may want to connect a serial terminal to
the console port, designated as the first serial port. This will allow you
to verify that your server is working and to configure the necessary
network settings. The console port is initially set for 9600 baud, 8 data
bits, one stop bit, and no parity.

When using a screw terminal block, you may have to connect from 2 to 6 wires
depending upon the desired MSS usage mode. Do not over-tighten the screws,
but make sure the wire is secure in the block.
Figure 2-5: Connecting Wire to Screw Terminal Blocks
B Connect the other end of the cable to your serial device’s serial port.
2 Connect the MSS to the network via one of the following methods.
❍
Connect one end of a twisted-pair 10/100BASE-T cable to the Ethernet
network. Connect the other end of the cable to the RJ45 Ethernet port on the
front of the MSS.
❍
Connect one end of a fiber optic cable to the Ethernet network. Connect the
other end of the cable to the fiber link ports (ST-style connector) on the front of
the MSS.
3 Supply power to the MSS. This can be done through either the MSS power jack or
the screw terminal power connector. Do not supply power to both the power jack and
the screw terminal at the same time.
A Connect one end of a power connector to the MSS via one of the following.
➜
Connect the barrel jack end of the power cable to the MSS power jack.
➜
Connect power to the 9-30V screw terminal power connector and to ground
and chassis ground.
B Supply power to the MSS by connecting the power cube end of the power cable
to a standard wall outlet.
When the MSS receives power, it will begin a three-step boot process.
❍
The MSS runs through a set of power-up diagnostics for approximately five
seconds. The OK and Serial LEDs should show varying patterns corresponding
to the test being run.
Note:
If there is a valid connection to a wired Ethernet network, the Link
LED should remain solid green or yellow once the unit has completed
booting.
TXRX

❍The MSS tries to obtain TCP/IP configuration information via DHCP, BOOTP,
and/or RARP. This procedure takes approximately 40 seconds if no hosts
answer the request, and boot messages will be sent to the console port. The OK
LED will blink green approximately three times per second, and occasionally
yellow as packets are sent and received.
Note: For more information on BOOTP, RARP, or DHCP, refer to your
operating system’s documentation.
❍The MSS determines if the code in the Flash ROMs is valid. If so, it loads the
code and begins normal execution. This step takes approximately five seconds.
Once the MSS is running normally, the Link LED should be solidly lit to indicate
a functioning wired Ethernet connection and the OK LED should blink once every
two seconds.
4Supply power to the attached serial device(s), if necessary.
5Ensure the MSS is working. There are a couple ways to check:
❍Wait for approximately 30 seconds after powering the unit up. If the Link LED
is solidly lit and the OK LED blinks green once every two seconds, the MSS is
operating normally.
❍If you have connected a serial terminal to the console port, press the Return
key. You should see several lines of start-up messages followed by a Local>
prompt.
2.3 Installing PC Cards
The following sections explain how to install different kinds of cards in the MSS PC card
slots. Not all PC card types or brands are supported. Check the Lantronix web site for a
complete list of currently supported technologies.
2.3.1 Installing an 802.11 Card
Although 802.11 networking is enabled by default, you may need to configure other 802.11
settings before the wireless card will work properly. To view your current 802.11
configuration, enter the Show 80211 command. This command may also be useful if you
experience any problems with your wireless network. See 802.11 Configuration on page 4-
16 for more details.
Note: You cannot have more than one 802.11 card installed in the MSS at
one time.

2.3.3 Installing a Modem Card
An installed modem card will appear as an additional serial port on the MSS. If only one
card is installed, the card will appear as Port 5 regardless of which slot it is in. If two cards
are installed, the card installed in the top slot (slot 1) will appear as Port 5 and the card in
the bottom slot (slot 2) will appear as Port 6.
If you are an SDK user, you can access the port by using device “tt4” for port 5 or “tt5” for
port 6.
Follow these steps to properly install supported modem cards.
1Power off the MSS by removing the plug from the outlet..
2Insert a supported modem card into one of the PC card slots.
3If desired, insert another supported modem card into the other PC card slot.
4Power up the MSS by plugging the power supply back in the outlet.
The MSS should boot up normally.
For instructions on how to use the modem card, see Modem Cards on page 4-22.
