xSenso 2100 User Guide 14
2: Introduction
xSenso 2100 is a compact DIN-rail or wall mount solution that enables sensors with analog
outputs (voltage or current) to easily and transparently send real-time data to any node on the
network or over the Internet. xSenso is an ideal solution for remote monitoring and data logging of
critical events in process control and automation applications. With its low port density, xSenso
can be affordably installed in dispersed locations. In applications where analog sensors and
controllers are used, xSenso can be configured to send alarms via emails or text messages when
readings are outside predefined ranges. These alarms allow control engineers to take immediate
corrective action when certain thresholds are met. Its embedded web server makes it possible to
monitor the input readings, chart or log the data using browsers on computers, smartphones, and
tablets from anywhere in the world.
Key Features
Power Supply: 9-30 VDC input voltage (1 terminal screw block and 1 barrel jack, where
when both are used, may operate as redundancy and failover)
Ethernet: 1 Port Ethernet 10Base-T or 100Base-TX (auto-sensing for speed, duplex and
cross-over CAT5 cable)
Analog Inputs: 2 configurable analog inputs with available ranges: ±100mV, ±1V, ±10V or
±20mA
USB Ports: One 2.0 full speed USB port for device management and configuration
Temperature Range: Storage and operating temperature between -40° to +85°C
Applications
The xSenso device server connects analog sensors such as those listed below to Ethernet
networks using the IP protocol family.
Temperature Gage
Environmental Data Sensors
Gas Monitoring Devices
Sensors measuring humidity, pressure, flow, level, force, weight and gas or air quality
Protocol Support
The xSenso device server contains a full-featured IP stack. Supported protocols include:
ARP, HTTP, HTTPS, UDP/IP, TCP/IP, SSH, SSL, RSS, ICMP, BOOTP,DHCP, Auto IP,
Telnet, SMTP, DNS, FTP, TFTP, XML and Syslog for network communications and
management.
TFTP for uploading/downloading files.
FTP and HTTP for firmware upgrades and uploading/downloading files.

2: Introduction
xSenso 2100 User Guide 15
TCP/IP, UDP/IP, Telnet, SSH, SSL, TCP AES and UDP AES for command/response based data
acquisition application or alarm triggered connection
HTTP/HTTPS web based monitoring of input readings, chart and data logging
SMTP for alarm triggered e-mail notification
Troubleshooting Capabilities
The xSenso offers a comprehensive diagnostic toolset that lets you troubleshoot problems quickly
and easily. Available from the CLI or Web Manager, the diagnostic tools let you:
View memory and IP socket information.
Perform ping and traceroute operations.
Conduct forward or reverse DNS lookup operations.
View all processes currently running on the xSenso, including CPU utilization.
View system log messages.
Configuration Methods
After installation, the xSenso 2100 requires configuration. For the unit to operate correctly on a
network, it must have a unique IP address on the network. There are four basic methods for
logging into the xSenso and assigning IP addresses and other configurable settings:
Web Manager: View and configure all settings easily through a web browser using the
Lantronix Web Manager. (See “Configuration Using Web Manager” on page 25.)
DeviceInstaller: Configure the IP address and related settings and view current settings on
the xSenso using a Graphical User Interface (GUI) on a PC attached to a network. You will
need the latest version of DeviceInstaller. (See “Using DeviceInstaller” on page 23.)
Command Mode: There are two methods for accessing Command Mode (CLI): making a
Telnet or SSH connection, or connecting a terminal (or a PC running a terminal emulation
program) to the unit’s USB port. (See Configuration Using the MGMT (USB) Port below and
the xSenso Command Reference Guide for instructions and available commands.)
XML: The xSenso supports XML-based configuration and setup records that make device
configuration transparent to users and administrators. XML is easily editable with a standard
text or XML editor. (See the xSenso Command Reference Guide for instructions and
commands.)
Configuration Using the MGMT (USB) Port
In order to configure and manage the device, connect the computer via USB cable to the xSenso
MGMT port and run a terminal emulation program (e.g., Tera Term).
Note: Device connection will be lost upon reboot. Close the connection (also close
emulation program terminal if needed), unplug and plug in the USB port, and reopen the
connection.
1. Install the USB device driver, as necessary.

2: Introduction
xSenso 2100 User Guide 16
Connection to the MGMT port is via USB-CDC-ACM. This driver is available in Windows. In
order to enable Windows to recognize the USB-CDC-ACM connection to the Lantronix device,
the driver installation file referenced below needs to be provided when prompted by the
Windows Device Driver Installation Wizard. For Windows 7 installation, it is recommended to
manually install the driver before plugging in the USB cable to the xSenso device port. This
can be done by installing a legacy driver for a COM port, with the Have Disk... option.
The device installation file (linux-cdc-acm.inf) may be accessed in one of two ways:
a. DeviceInstaller installation directory (typically at c:\Program File\Lantronix\Device
Installer\4.3).
b. Follow the instructions in Appendix E: USB-CDC-ACM Device Driver File for Windows
Hosts to create the .inf file and follow the windows driver installation steps as outlined
above.
2. Connect the USB cable to the MGMT (USB) port of the xSenso device.
3. Connect the USB cable from the xSenso to the USB port on your computer.
4. Apply power. If drivers are installed, a virtual com port will be created on the computer.
5. Launch an emulation program terminal (e.g., Tera Term) and select the virtual com port.
6. Open up the virtual com port. The serial setting should be 9600, 8,none, and 1.
7. Click OK.
8. Press Enter in the terminal window. You will be prompted to login.
9. Login to the xSenso to configure it. The default login and password:
User Name: admin
Password: PASS
Addresses and Port Numbers
Hardware Address
The hardware address is also referred to as the Ethernet address, physical address, or MAC
address. Sample hardware address:
00-80-A3-14-1B-18
00:80:A3:14:1B:18
IP Address
Every device connected to an IP network must have a unique IP address. This address references
the specific unit.
Port Numbers
Every TCP connection and every UDP datagram is defined by a destination and source IP
address, and a destination and source port number. For example, a Telnet server commonly uses
TCP port number 23.
The following is a list of the default server port numbers running on the xSenso:

2: Introduction
xSenso 2100 User Guide 17
TCP Port 22: SSH Server (Command Mode configuration)
TCP Port 23: Telnet Server (Command Mode configuration)
TCP Port 80: HTTP (Web Manager configuration)
TCP Port 21: FTP
UDP Port 30718: LDP (Lantronix Discovery Protocol) port
TCP/UDP Port 10001: Tunnel 1 (see note below)
Note: Additional TCP/UDP ports and tunnels will be available, depending on the product
type. The default numbering of each additional TCP/UDP port and corresponding tunnel
will increase sequentially (i.e., TCP/UDP Port 1000X: Tunnel X).

The product information label on the unit contains the
following information about the specific unit:
Bar code
Product Revision
Part Number

You can reset the xSenso to factory default settings, including clearing the network settings. The
IP address, gateway, and netmask are set to 00s.
To reset the unit to factory defaults:
1. Place the end of a paper clip or similar object into the reset opening (see Figure 3-1) and press
and hold down micro switch during a power cycle for a minimum of 25 seconds.
2. Remove the paper clip to release the button. The unit will continue the boot process restoring
it back to the original factory default settings.
