Resetting the Link
Once the start sequence has been received by the Modulator it will
continue to receive data until it has a complete message. To ensure that
the Modulator is ready to receive a new message, sending a series of 255
space characters (0x20) will reset the internal buffers. This, however,
should not be required unless there has been some previous
communications problem. In doing this, the Modulator may send an error
indicating that the message is too long.
5.2 Messages to the Modulator
5.2.1 Functionality Constraints
Certain functionality of the Modulator is dependent upon the specific
Modulator model, the hardware options fitted and the software options
installed in it. The validity of some parameter values in configuration
messages to the Modulator is dependent upon the functionality available.
Parameter values are validated by the Modulator and accepted or rejected
as appropriate. For example, 8PSK modulation and its associated FEC rate
8/9 are only available if the Higher Order Modulation (HOM) software
option is installed.
5.2.2 Activate Configuration
Sending this message activates a stored configuration in the Modulator.
Configurations 1-8 are user-stored configurations, but Configuration 9 is
the configuration of default values for Modulator parameters. These default
values are built into the application code.
