Ajdustments in general

Information

Generally there are few adjustments to be made in ML Gateway, when modules 
has been replaced. 
To maintain or service ML Gateway there is no need for a special ServiceTool as 
known from other Bang & Olufsen products. All types of service or adjustments 
are executed from a web-based user interface.

Survey of adjustments

The follwing adjustments/settings are available in the web-based user interface:

-  Network Settings.
-  Setting up the date and time in the product.
-  Setting up the text size (to fit screen resolution of the web interface).
-  Change password (login password to ML Gateway).
-  Master Link Gateway Protocol settings.
-  Serialising the serial number into the product (PCB52, Digi module).
-  Backup/restore the customer’s data to a new PCB52, Digi module.

Additional information

!  The web interface is organised into a series of screens which can be selected by 

means of the navigation bars.
Try to avoid using the browser’s back and forward navigation buttons, as you may 
lose the information you are entering.
Also, note that changing to another screen does not save the modifications you 
have made. There are ‘Apply’ or ‘Save’ buttons next to most controls and data 
fields.

!  When a configuration is uploaded to ML Gateway, e.g. when PCB52, Digi module 

is replaced, the uploaded project will not be activated automatically (it will only 
replace the current EDIT version). 
It is required to TEST and then SAVE the newly uploaded configuration in order to 
activate it. For this procedure please refer to the ‘Programming’ section in ML 
Gateway.

!  When it is required to initialise the serial number in to ML Gateway (only relevant 

when PCB52, Digi module is replaced) a command line interface (CLI) must be 
used. For this purpose it is recommended to use
