Chapter 16 Firmware and Configuration File Maintenance

The following table describes some of the commands that you may see in third party FTP 
clients.

The G-1000 v2 supports the up/downloading of the firmware and the configuration file using 
TFTP (Trivial File Transfer Protocol) over LAN. Although TFTP should work over WAN as 
well, it is not recommended.

To use TFTP, your computer must have both telnet and TFTP clients. To backup the 
configuration file, follow the procedure shown next:

1 Use telnet from your computer to connect to the G-1000 v2 and log in. Because TFTP 

does not have any security checks, the G-1000 v2 records the IP address of the telnet 
client and accepts TFTP requests only from this address.

2 Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 – System 

Maintenance.

3 Enter command “sys stdio 0” to disable the SMT timeout, so the TFTP transfer will not 

be interrupted. Enter command “sys stdio 5” to restore the five-minute SMT timeout 
(default) when the file transfer is complete.

4 Launch the TFTP client on your computer and connect to the G-1000 v2. Set the transfer 

mode to binary before starting data transfer.

5 Use the TFTP client (see the example below) to transfer files between the G-1000 v2 and 

the computer. The file name for the configuration file is rom-0 (rom-zero, not capital o).

Note that the telnet connection must be active and the SMT in CI mode before and during the 
TFTP transfer. For details on TFTP commands (see following example), please consult the 
documentation of your TFTP client program. For UNIX, use “get” to transfer from the G-1000 
v2 to the computer and “binary” to set binary transfer mode.
