Using TFTP: Command Line Interface
To download new firmware from a computer:
1. Enter the following from a TFTP command line interface:
tftp –i <ip address> put <local filename> <destination file name>
The following examples demonstrate the TFTP command sequence to download
the .rom file and the .cob file:
tftp –i 192.168.1.111 put UDS2100_6102.rom U4
tftp –i 192.168.1.111 put UDS2100_webm_1403.cob WEB4
2. In the Remote file name field, enter the current internal operational code (U4) or
WEB1 to WEB19 for the internal Web interface.

using DeviceInstaller to download the *.ROM file over the serial port.
To recover firmware:
1. Connect the COM interface of your PC to serial port 1 of the unit.
2. Start DeviceInstaller. If your PC has more than one network adapter, a message
displays. Select an adapter and click OK.
3. From the Tools menu, select Advanced/Recover Firmware. The Serial Port
Firmware Upgrade window displays.
4. For Port on PC, enter the COM port on the PC that is connected to the serial
port of the Lantronix unit.
