Let's assume that the following routing is saved as user settings:
DIGITAL OUTPUT 1
is connected to
DIGITAL INPUT 2
DIGITAL OUTPUT 2
is connected to
DIGITAL INPUT 1
Autoswitch
enabled
Let's further assume that there is a sync signal on
DIGITAL INPUT 1
, and no sync signal on
DIGITAL INPUT 2
.
Therefore the actual configuration differs from the target configuration (the first output is
automatically switched to the second input).

Result:
The status register shows the actual current configuration and the saved user settings.
Command “h”: restore user settings
Description: Via this command the
RCM
tells the
RCS
of class
m
to restore the configuration which is
saved in the user settings. This command has impact on:
the connection of
DIGITAL INPUT 1
the connection of
DIGITAL INPUT 2
the status of a
uto switch
The
RCS
executes the command and sends the acknowledge which informs via the status
register about status of auto switch, outputs and inputs.
Example.
The comamnd
h
is sent to the second
RCS
:
Message

Assumption:The following configuration represent the user settings: sync signal on
DIGITAL INPUT 1
, no sync signal on
DIGITAL INPUT 2
, and both outputs are connected to
DIGITAL INPUT 1
, while auto switch is disabled.

Result:
The user settings are restored, previous made modifications of these connections and
functionalities are re-called.
Restoring configurations is an undo command.
