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
everything sent to the connection arrives correctly at the target.
Supported protocols include:
ARP, UDP, TCP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, and SNMP for
network communications.
TCP, UDP, 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, leveraging 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 DeviceInstaller on page 16.)
Web Manager: Through a web interface configures the UDS settings using the
Lantronix Web Manager. (See 4: Configuring the UDS Using Web Manager.)
Serial and Telnet Ports: 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 5: Configuring the UDS Using Telnet or the Serial Port.)
