Using a method called serial tunneling, the xDirect encapsulates serial data into packets and
transports them over Ethernet. Using two xDirect units, connected by a network, virtual serial
connections can extend across a facility or around the world.
Figure 2-1 Serial Tunneling Example
The Com Port Redirector software available for download at
www.lantronix.com/support/downloads simplifies the integration process by extending the
functionality of COM-port-based Windows™ applications. Virtual COM ports, mapped to remote
device servers on the network, can replace direct serial connections.

2: Introduction
Protocol Support
The xDirect uses the Internet Protocol (IP) for network communications and the Transmission
Control Protocol (TCP) to assure that no data is lost or duplicated and that everything sent to the
connection arrives correctly at the target.
Supported protocols include:
ARP, UDP/IP, TCP/IP, BOOTP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, and SNMP for
network communications.
TCP/IP, UDP/IP, and Telnet for connections to the serial port as well as Telnet Com Port
Control.
TFTP for firmware updates.
IP for addressing, routing, and data block handling over the network.
User Datagram Protocol (UDP) for typical datagram applications in which devices interact with
other devices without a point-to-point connection.
Additional Features
Modem Emulation: In modem emulation mode, the xDirect can replace dial-up modems. The unit
accepts modem AT commands on the serial port and then establishes a network connection to the
end device. This arrangement leverages network connections and bandwidth to eliminate
dedicated modems and phone lines.
Built-in Web Server: The xDirect includes a built-in web server for configuring the unit and
displaying operating and troubleshooting information on the attached links to online support.
Security Features: Password Protection and 256-bit AES Encryption
Configuration Methods
After installation, the xDirect requires configuration. For the unit to operate correctly on a network,
it must have a unique IP address on the network. There are three basic methods for logging into
the xDirect and assigning IP addresses and other configurable settings:
Web Manager: View and configure all settings easily through a web browser using the
DeviceInstaller: Configure the IP address and related settings and view current settings on
the xDirect using a Graphical User Interface (GUI) on a PC attached to a network. You will
Serial and Telnet Ports: Use Setup Mode, a command line interface. There are two
approaches to accessing Setup Mode: making a Telnet connection to the network port (9999)
or connecting a terminal (or a PC running a terminal emulation program) to the unit's serial

in the packaging.
Note: The provided power supply is 5 VDC 1A. For all xDirect units power can also
be supplied via pin 9 (+) and pin 5 (-) on the DB9F connector (voltage range = 5 VDC
to 15 VDC). The xDirect will draw 1.3W max power.
Required Information
Before configuring the xDirect, have the following information available:
Hardware Address
Take note of the unit’s hardware address (also known as the Ethernet or MAC address). It is on
the product label, in the format: 00-80-A3-XX-XX-XX, where the XXs are unique numbers
Hardware Address: _____-_____-_____-_____-_____-_____
IP Address
The xDirect must have a unique IP address on your network. This address references the specific
unit. By default, the unit is DHCP-enabled and automatically assigned an IP address on DHCP-
enabled networks. If you are assigning a static IP address, the systems administrator generally
provides the IP address, subnet mask, and gateway.
Note: The factory default IP address is 0.0.0.0 to enable DHCP, BOOTP, and AutoIP.
When the units boots, it sends a DHCP broadcast to try and get an IP address. If it
receives no reply from a DHCP server, the xDirect tries BOOTP. If the xDirect does not
receive a response from BOOTP, it reverts to an AutoIP address.

indicates the end of transmission. The default setting is 1.
Pack Control
Enable Packing
Select to enable packing on the xDirect.
Two firmware-selectable packing algorithms define how and when packets are
sent to the network.
The standard algorithm is optimized for applications in which the unit is used in
a local environment, allowing for very small delays for single characters, while
keeping the packet count low.
The alternate packing algorithm minimizes the packet count on the network
and is especially useful in applications in a routed Wide Area Network (WAN).
Adjusting parameters in this mode can economize the network data stream.
Disabled by default.
Idle Gap Time
Select the maximum time for inactivity. The default time is 12 milliseconds.

6: Configuration Via Telnet or Serial Port (Setup
Mode)
You must configure the unit so it can communicate on a network with your serial device. As an
alternative to using a web browser, as described in the previous chapter, you can use the following
procedures remotely or locally:
Use a Telnet connection to configure the unit over the network.
Use a terminal or terminal emulation program to access the serial port locally.
The series of prompts at which you enter configuration settings is called Setup Mode.
Note: Detailed information about other setup methods are available from your Lantronix
Sales Associate.
The unit’s configuration is stored in nonvolatile memory and is retained without power. You can
change the configuration at any time. The unit performs a reset after the configuration has been
changed and stored.
This chapter explains how to access and use Setup Mode. To complete the configuration,
Note: The menus in the configuration chapters show a typical device. Your device may
have different configuration options.
Accessing Setup Mode
Telnet Connection
To configure the unit over the network, establish a Telnet connection to port 9999.
Note: You can also use DeviceInstaller to access Telnet. Select the device from the
main window list, and click the Telnet Configuration tab. Skip steps 1 and 2.
To establish a Telnet connection:
1. From the Windows Start menu, click Run and type the following command, where x.x.x.x is
the IP address, and 9999 is the unit’s fixed network configuration port number:
Windows: telnet x.x.x.x 9999

DHCP Name
If a DHCP server has automatically assigned the IP address and network settings, you can
discover the unit by using the DeviceInstaller network search feature or Monitor Mode (see
Note: When you enter Monitor Mode from the serial port with network connection
enabled and issue the NC (Network Communication) command, you see the unit’s IP
configuration.
There are three methods for assigning DHCP names to the unit.
Default DHCP Name: If you do not change the DHCP name, and you are using an IP of
0.0.0.0, then the DHCP name defaults to XX.XX.XX.XX (XXXXXX is the last 6 digits of the
MAC address shown on the label on the bottom/side of the unit). For example, if the MAC
address is 00-20-4A-12-34-56, then the default DHCP name is C123456.
Custom DHCP Name: You can create your own DHCP name. If you are using an IP address
of 0.0.0.0, then the last option in Server configuration is Change DHCP device name. This
option allows you to change the DHCP name to an alphanumeric name (LTX in our example).
Change DHCP device name (not set) ? (N) Y
Enter new DHCP device Name : LTX
Numeric DHCP Name: You can change the DHCP name by specifying the last octet of the IP
address. When you use this method, the DHCP name is LTXYY where YY is what you chose
for the last octet of the IP address. If the IP address you specify is 0.0.0.12, then the DHCP
name is LTX12. This method only works with 2 digit numbers (01-99).

b) Response
Character Response A single character is transmitted to the serial port when there is a change in
connection state: C = connected, D = disconnected, N = host unreachable. The
IP address of the host connecting to the CoBos device will be provided when you
use verbose mode.
This option is overridden when the Active Start Modem Mode or Active Start
Host List is in effect. Default setting is Nothing (quiet).
c) Active Startup
No Active Startup
Does not attempt to initiate a connection under any circumstance. Default setting.
With Any Character
Attempts to connect when any character is received from the serial port.
With active Modem
Control in
Attempts to connect when the Modem Control In input changes from not
asserted to asserted.
With a Specific Start Attempts to connect when it receives a specific start character from the serial port.
Character
The default start character is carriage return.
Manual Connection
Attempts to connect when directed by a command string received from the serial
port. The first character of the command string must be a C (ASCII 0x43), and the
last character must be either a carriage return (ASCII 0x0D) or a line feed (0x0A).
No blanks or space characters may be in the command string. Between the first
and last command string characters must be a full or partial destination IP address
and may be a destination port number.
The IP address must be in standard decimal-dot notation and may be a partial
address, representing the least significant 1, 2, or 3 bytes of the remote IP
address. The period is required between each pair of IP address numbers.
If present, the port number must follow the IP address, must be presented as a
decimal number in the range 1-65535, and must be preceded by a forward slash
(ASCII 0x2F). The slash separates the IP address and the port number. If you
omit the port number from a command string, the internally stored remote port
number starts a connection.
If a partial IP address is presented in a command string, it is interpreted to be the
least significant bytes of the IP address and uses the internally stored remote IP
address to provide the most significant bytes of the IP address. If the IP address
entered is 0.0.0.0/0, the device server enters Monitor Mode.
For example, if the remote IP address already configured in the unit is 129.1.2.3,
then an example command string would be C3/7. (This would connect to
129.1.2.3 and port 7.) You may also use a different ending for the connection
string. For example, C50.1/23 would connect you to 129.1.50.1 and port 23.
If an IP address does not follow the first command string character (which is "C"),
the subsequent character string is interpreted as the host name and domain to be
used in DNS lookup. This character string can include a destination port number
as well. The port number can be preceded by either a forward slash (/) or a colon (
: ).

Host List Option (Hostlist)
Autostart (Automatic
Connection)
If you enable Autostart, the unit automatically connects to the remote IP
address and remote port specified when the firmware starts.
Hostlist
If you enable this option, the device server scrolls through the hostlist until it
connects to a device listed in the hostlist table. Once it connects, the unit
stops trying to connect to any others. If this connection fails, the unit
continues to scroll through the table until it is able to connect to another IP in
the hostlist.
Hostlist supports a minimum of 1 and a maximum of 12 entries. Each entry
contains the IP address and the port number.
The hostlist is disabled for Manual and Modem Modes. The unit does not
accept a data connection from a remote device when the hostlist option is
enabled.

To enable the hostlist:
1. Enter a Connect Mode of 0x20 (2X), where X is any digit. The menu shows you a list of current
entries already defined in the product.
2. To delete, modify, or add an entry, select Yes. If you enter an IP address of 0.0.0.0, that entry
and all others after it are deleted.
3. After completing the hostlist, repeat the previous step if necessary to edit the hostlist again.
4. For Retrycounter, enter the number of times the Lantronix unit should try to make a good
network connection to a hostlist entry that it has successfully ARPed. The range is 1-15, with
the default set to 3.
5. For Retrytimeout, enter the number of seconds the unit should wait before failing an
attempted connection. The time is stored as units of milliseconds in the range of 10-65535.
The default setting is 250.
d) Datagram Type
Directed UDP
When selecting this option, the prompt requests the Datagram type. Enter 01 for
directed or broadcast UDP. Datagrams of type 01 can be sent as a broadcast by
enabling this option. The default is not to broadcast.
Note: Datagrams are sent as subnet-directed broadcasts.
When the UDP option is in effect, the unit never attempts to initiate a TCP
connection because it uses UDP datagrams to send and receive data.
e) Modem Mode
In Modem (Emulation) Mode, the unit presents a modem interface to the attached serial device. It
accepts AT-style modem commands and handles the modem signals correctly.
Normally, there is a modem connected to a local PC and a modem connected to a remote
machine. A user must dial from the local PC to the remote machine, accumulating phone charges
for each connection. Modem Mode allows you to replace modems with xDirects, and to use an
Ethernet connection instead of a phone call. By not having to change communications
applications, you avoid potentially expensive phone calls.
To select Modem Mode, set the Connect Mode to C6 (no echo), D6 (echo with full verbose), D7
(echo with numeric response), CF (modem responses only, numeric response), or CE (modem
responses only, full verbose).
Note: If the unit is in Modem Mode, and the serial port is idle, the unit can still accept
network TCP connections to the serial port if Connect Mode is set to C6 (no echo), D6
(echo with full verbose), D7 (echo with numeric response, CF (modem responses only,
numeric response), or CE (modem responses only, full verbose).
Without Echo
In Modem Mode, echo refers to the echo of all of the characters
entered in command mode; it does not mean to echo data that is
transferred. Quiet Mode (without echo) refers to the modem not
sending an answer to the commands received (or displaying what
was typed).

Error
Received commands must begin with the two-character sequence AT and be terminated with a
carriage return character.
The unit ignores any character sequence received not starting with AT, and only recognizes and
processes single AT-style commands. The unit treats compound AT commands as unrecognized
commands.
If the Full Verbose option is in effect, the unit responds to an unrecognized command string that is
otherwise formatted correctly (begins with AT and ends with carriage return) with the "OK"
message and takes no further action.
If the Numeric Response option is in effect, the unit responds to an unrecognized command
string that is otherwise formatted correctly with a "0" message and takes no further action.
When an active connection is in effect, the unit transfers data and does not process commands
received from the serial interface.
When a connection is terminated or lost, the unit reverts to command mode.
When an active connection is in effect, the unit terminates the connection if it receives the
following sequence from the attached serial device:
No serial data is received for one second.
The character sequence +++ is received, with no more than one second between each two
characters.
No serial data is received for one second after the last + character. At this time, the unit
responds affirmatively per the selected echo/response mode.

Pack Control
The packing algorithms define how and when packets are sent to the network. The standard
algorithm is optimized for applications in which the unit is used in a local environment, allowing for
very small delays for single characters, while keeping the packet count low. The alternate packing
algorithm minimizes the packet count on the network and is especially useful in applications in a
routed Wide Area Network (WAN). Adjusting parameters in this mode can economize the network
data stream.
Pack control settings are enabled in Flush Mode. Set this value to 00 if you do not need specific
functions.
Note: All bit positions in the table that are blank represent “don’t care” bits for that
particular option, which can be set to either a 0 or 1 value.

Packing Interval
Packing Interval defines how long the unit should wait before sending accumulated characters.
This wait period is between successive network segments containing data. For alternate packing,
the default interval is 12 ms.
Trailing Characters
In some applications, CRC, Checksum, or other trailing characters follow the end-of-sequence
character; this option helps to adapt frame transmission to the frame boundary. The default setting
is 00 (none).
Send Characters
If 2-Byte Send Character Sequence is enabled, the unit interprets the sendchars as a 2-byte
sequence; if this option is not enabled, the unit interprets them independently. The default
setting is 0 (disabled).
If Send Immediately After Characters is not set, any characters already in the serial buffer
are included in the transmission after a "transmit" condition is found. If this option is set, the

unit sends immediately after recognizing the transmit condition (sendchar or timeout). The
default setting is 0.
Note: A transmission might occur if status information needs to be exchanged or an
acknowledgment needs to be sent.
DisConnTime (Inactivity Timeout)
Use this parameter to set an inactivity timeout. The unit drops the TCP connection to the local port
if there is no activity on the serial line before the set time expires. Enter time in the format mm:ss,
where m is the number of minutes and s is the number of seconds.
DisConnTime (00:00) ?:
To disable the inactivity timeout, enter 00:00. Range is 0 (disabled) to 5999 seconds (99 minutes,
59 seconds). Default setting is 0.
Send Characters
Enter up to two characters in hexadecimal representation in sendchar.
SendChar 1 (00) ? _
SendChar 2 (00) ? _
If the unit receives a character on the serial line that matches one of these characters, it sends the
character immediately, along with any awaiting characters, to the TCP connection. This action
minimizes the response time for specific protocol characters on the serial line (for example, ETX,
EOT). Setting the first sendchar to 00 disables the recognition of the characters. Alternatively, the
Telnet Terminal Type
This parameter displays only if you enabled the terminal type option in Disconnect Mode. With this
option enabled, you can use the terminal name for the Telnet terminal type. Enter only one name.
With terminal type option enabled, the unit also reacts to the EOR (end of record) and binary
options, useful for applications like terminal emulation to IBM hosts.
Channel (Port) Password
This parameter appears only if the channel (port) password option is enabled in Disconnect Mode.
With this option enabled, you can set a password on the serial port. The default setting is all 0s.

xDirect supports 128-, 192-, and 256-bit encryption key lengths.
Note: Configuring encryption should be done through a local connection to the serial
port of the xDirect, or via a secured network connection. Initial configuration information,
including the encryption key, is sent in clear text over the network.
To configure AES encryption on the xDirect:

2. When prompted, enter the encryption key length. The xDirect supports 128-, 192-, and 256-bit
encryption key lengths.
3. When prompted to change keys, select Y.
4. At the Enter Keys prompt, enter your encryption key. The encryption keys are entered in
hexadecimal. The hexadecimal values are echoed as asterisks to prevent onlookers from
seeing the key. Hexadecimal values are 0-9 and A-F.
For a 128-bit key length, enter 32 hexadecimal characters.
For a 192-bit key length, enter 48 hexadecimal characters.
For a 256-bit key length, enter 64 hexadecimal characters
5. Continue pressing Enter until you return to the Change Setup menu.
6. From the Change Setup menu, select option 9 to save and exit.
Encryption only applies to the port selected for data tunneling (default 10001), regardless of
whether you are using TCP or UDP.
Generally, one of these situations applies:
Encrypted xDirect-to-xDirect communication. Be sure to configure both xDirect devices with
the same encryption key.
Third-party application to xDirect-encrypted communication: xDirect uses standard AES
encryption protocols. To communicate successfully, products and applications on the peer
side must use the same protocols and the same encryption key as the xDirect.
Lantronix Secure Com Port Redirector provides an encrypted connection from Windows-
based applications to the xDirect. Information about SCPR is at www.lantronix.com/device-
networking/utilities-tools/scpr A 30-day trial version of SCPR is available.
Note: Developers can license the Lantronix Encryption Library Suite.
Enable Enhanced Password
This setting defaults to the N (No) option, which allows you to set a 4-character password that

You can obtain the most up-to-date firmware and release notes for the unit from the Lantronix web
Reloading Firmware
There are several ways to update the unit's internal operational code (*.ROM): using
DeviceInstaller (the preferred way), using TFTP, or using the serial port. You can also update the
unit's internal Web interface (*.COB) using TFTP or DeviceInstaller.
Here are typical names for those files. Check the Lantronix web site for the latest versions and
release notes.
Table 10-1 Firmware Files
ROM File
COB
xdirect_6900.rom
xdirect_webm_2000.cob
Please refer to the DeviceInstaller online Help for information about reloading firmware using
DeviceInstaller. The other methods are discussed below.
Using TFTP: Graphical User Interface
To download new firmware from a computer:
1. Use a TFTP client to send a binary file to the unit (*.ROM to upgrade the unit's internal
operational code and *.COB to upgrade its internal Web interface).
Note: TFTP requires the .ROM (binary) version of the unit's internal operational code.
2. In the TFTP server field, enter the IP address of the unit being upgraded.
3. Select Upload operation and Binary format.
4. Enter the full path of the firmware file in the Local file name field.
5. In the Remote file name field, enter the current internal operational code (U5) or WEB1 to

1. Connect Power Input only to IEC Class III or NEC Class 2 Circuits. Connect POE only to IEEE 802.3
series Standard (Ethernet).
2. In the case of more than one power sources are plugged in for power redundancy (e.g. PoE and DB9F
pins, or mini USB-B and DB9F pins, or PoE and DB9F pins), unit's power usage is likely provided between
sources. Also, note that this redundancy configuration does not guarantee an uninterrupted operation at
the moment when one source goes out of service.
3. Lantronix power supply shipped with xDirect is UL certified 0° to +40°C operating only, thus, users are cau-
tioned when using with xDirect in environments outside of this temperature range. Users can:
a) use both the xDirect and the power supply at 0° to +40°C, or
b) place the power supply in the environment temperature 0° to +40°C, and run the output cord to xDirect
which could be placed in its own environment operating -40° to +75°C, or
c) use a power supply that has similar rated temperature to that of xDirect so that the power supply and
xDirect can be placed in the same environment.

Appendix D: Alternative Ways to Assign an IP
Address
Earlier chapters describe how to assign a static IP address using DeviceInstaller, Web Manager,
and Setup Mode (through a Telnet or serial connection). This section covers other methods for
assigning an IP address over the network.
DHCP
The unit ships with a default IP address of 0.0.0.0, which automatically enables DHCP. If a DHCP
server exists on the network, it provides the unit with an IP address, gateway address, and subnet
mask when the unit boots up.
You can use the DeviceInstaller software to search the network for the DHCP-assigned IP address
and add it to the list of devices retrieved.
Note: This DHCP address does not appear in the unit’s Setup Mode or in Web
Manager. You can determine your unit’s DHCP-assigned IP address in Monitor Mode.
When you enter Monitor Mode from the serial port with network connection enabled and
issue the NC (Network Communication) command, you see the unit’s IP configuration.
AutoIP
The unit ships with a default IP address of 0.0.0.0, which automatically enables
Auto IP within the unit. AutoIP is an alternative to DHCP that allows hosts to obtain an IP address
automatically in smaller networks that may not have a DHCP server. A range of IP addresses
(from 169.254.0.1 to 169.254.255.1) has been explicitly reserved for AutoIP-enabled devices. Do
not use this range of Auto IP addresses over the Internet.
If your unit cannot find a DHCP server, and you have not manually assigned an IP address to
it, the unit automatically selects an address from the AutoIP reserved range. Then, your unit
sends out a (ARP) request to other nodes on the same network to see whether the selected
address is being used.
If the selected address is not in use, then the unit uses it for local subnet communication.
If another device is using the selected IP address, the unit selects another address from the
AutoIP range and reboots. After reboot, the unit sends out another ARP request to see if the
selected address is in use, and so on.
AutoIP does not replace DHCP. The unit continues to look for a DHCP server on the network. If it
finds a DHCP server, the unit switches to the DHCP server-provided address and reboots.
Note: If a DHCP server is found, but it denies the request for an IP address, the unit
does not attach to the network, but waits and retries.
AutoIP can be disabled by setting the unit’s IP address to 0.0.1.0. This setting enables DHCP but
disables AutoIP.

Appendix D: Alternative Ways to Assign an IP Address
BOOTP
Similar to DHCP, but for smaller networks. Automatically assigns the IP address for a specific
duration of time.
ARP and Telnet
If the unit has no IP address, you can use Address Resolution Protocol (ARP) method from UNIX
and Windows-based systems to assign a temporary IP address.
To assign a temporary IP address:
1. On a UNIX or Windows-based host, create an entry in the host's ARP table using the intended
IP address and the hardware address of the unit (on the product label on the bottom of the
unit).
arp -s 191.12.3.77 00:20:4a:xx:xx:xx (Unix)
arp -s 191.12.3.77 00-20-4a-xx-xx-xx (Windows)
Note: For the ARP command to work on Windows 95, the ARP table on the PC must
have at least one IP address defined other than its own.
2. If you are using Windows 95, type ARP -A at the DOS command prompt to verify that there is
at least one entry in the ARP table. If the local machine is the only entry, ping another IP
address on your network to build a new entry in the ARP table; the IP address must be a host
other than the machine on which you are working. Once there is at least one additional entry in
the ARP table, use the following command to ARP an IP address to the unit:
arp -s 191.12.3.77 00-20-4a-xx-xx-xx
3. Open a Telnet connection to port 1. The connection fails quickly, but the unit temporarily
changes its IP address to the one designated in this step.
telnet 191.12.3.77 1
4. Open a Telnet connection to port 9999, and press Enter within five seconds to go into Setup
Mode. If you wait longer than five seconds, the unit reboots.
telnet 191.12.3.77 9999
Note: The IP address you just set is temporary and reverts to the default value when the
unit’s power is reset, unless you configure the unit with a static IP address and store the
changes permanently.

Appendix E: Binary to Hexadecimal Conversions
Many of the unit's configuration procedures require you to assemble a series of options
(represented as bits) into a complete command (represented as a byte).
The resulting binary value must be converted to a hexadecimal representation.
Use this chapter to learn to convert binary values to hexadecimals or to look up hexadecimal
values in the tables of configuration options. The tables include:
Command Mode (serial string sign-on message)
AES Keys

Conversion Table
Hexadecimal digits have values ranging from 0 to F,
which are represented as 0-9, A (for 10), B (for 11),
etc. To convert a binary value (for example, 0100
1100) to a hexadecimal representation, treat the
upper and lower four bits separately to produce a two-
digit hexadecimal number (in this case, 4C). Use the
following table to convert values from binary to
hexadecimal.
