The „tftpd32“ program is started directly from the folder with the U 262 update files. In the window
that opens, click on the „Settings“ button first and make the settings as shown in Figure 21:
Figure 20: Settings for the tftpd32 TFTP program
To start the update, the server address which is input into the „(T)FTP Server address“ line now
needs to be the IP address of the local computer (Figure 19), and the protocol needs to be set to
TFTP. It is therefore also no longer necessary to input a username and a password. In the „File“
line, select the „Update“ option, and start the update by clicking on the „Submit“ button.
NOTE:
A reboot or network failure during an update procedure can result in the U 262 Gateway software
crashing fatally. The device would then need to be sent to the ASTRO factory for repair.
