Protocol Support
The UDS 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.
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 UDS 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 UDS includes a built-in web server for configuring the unit and
displaying operating and troubleshooting information on the attached links to online
support.
Configuration Methods
After installation, the UDS 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 UDS and assigning IP addresses and other configurable
settings:
DeviceInstaller
: Configure the IP address and other network settings on the UDS using
a Graphical User Interface (GUI) on a PC attached to a network.
(See
4: Using DeviceInstaller
.)
Web-Manager
: Through a web browser, configure the UDS settings using the Lantronix
Web-Manager. (See
5: Configuration Using Web-Manager
.)
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 port. See
6: Configuration via Telnet or Serial Port (Setup Mode).
