protocol (FTP/HTTP/HTTPS).
Name—a login to access the automatic update server.
Password—a password to access the automatic update server.
Server—IP address or network name of the automatic update server when the static source is
selected; update.local name is used by default.
Update configuration—specifies to use automatic configuration updates.
Configuration file name—name and path to the configuration file located on the automatic update
server; MAC.cfg by default, where MAC is the MAC address of the device in the xx.xx.xx.xx.xx.xx
format.
Configuration upgrade period, min—time interval in minutes between requests for a configuration
file sent to the automatic update server.
Software update—enables automatic firmware updates.
Software version file name—name of the manifest file on the automatic update server that

4.1.1.1 Format of Options 66 and 67
Option 66 is required to retrieve the IP address or domain name of the automatic update server.
Syntax:
“<IP address or domain name of the update server>“
Example:
“update.local“
or
“192.168.1.3“
Option 67 is required to retrieve the path to the file with firmware version description (the manifest file)
and the path to the configuration file.
Syntax:
“<Path to smg4.manifest (or smg2.manifest) file>;<Path and name of the configuration file>“
Example:
“/smg4/firmware/smg4.manifest;/smg4/conf/<MAC>.cfg“
“/smg2/firmware/smg2.manifest;/smg2/conf/<MAC>.cfg”
If a device receives a configuration file name in the format "<MAC>.cfg" from the server, it automatically
replaces <MAC> with its own MAC address in the format 11.22.33.44.55.66 when addressing the server. This
means that the server should contain a configuration file named 11.22.33.44.55.66.cfg.
