After the new firmware has been transferred to the DGy 201, the final 
step is to install the firmware into DGy 201 non volatile memory. 
Installation of the DGy 201 firmware requires the ufw command to be 
issued from a command line interface. You can use either the serial (RS-
232) port or open a Telnet session on the Ethernet (10/100 BASE-T) port 
to complete this final step. 

Connect to the DGy 201 by either the serial port using a serial 
emulator or the Ethernet port as a telnet session.

Verify that you have established communication to the 
command line interface by typing either help at the command 
line prompt. If the connection is set up correctly the DGy 201 
should respond with a list of commands.

Type the command ufw and press ENTER.

The DGy 201 will prompt you with a warning message: 

 

“This command will replace the current firmware with the 
firmware you just downloaded and restart the system. Do you 
want to proceed (y/n) ?”

Type ‘y to proceed or “n” to terminate the process.

When the installation is complete the DGy 201 will automatically 
reboot. This is indicated by the front panel LED indicators being 
turned on simultaneously. Wait fifteen seconds for the boot 
process to complete before moving on to the next step.

Reconnect the serial emulator or start a new Telnet session with 
DGy 201 and type “ver”. DGy 201 should respond with the new 
firmware version number. The firmware upgrade process is now 
complete.

Note Communications 

with 

the 

unit will be lost during the 

installation process. This is normal and does not 
indicate that there is a problem with the installation 
process. This process may take several minutes.

Do NOT turn the power off during this time.
