2: Introduction
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, 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
Additional Features
Modem Emulation: In modem emulation mode, the UDS can replace
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 Assigning the IP Address: DeviceInstaller on page 16.)
Lantronix
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 5: Configuration via Telnet or Serial Port (Setup Mode).)
