Signal Present Meter Block

Please refer to the TTP Overview section for more details on the controlling Tesira devices using the TTP protocol.

Each element of the command instruction is delimited by one or more spaces. The commands are case sensitive and upper and lower case characters are used.

The TTP string to adjust a DSP object attribute is structured in the following order:

Instance_Tag Command Attribute [Index] [Value] LF

Instance Tag: Is always required. Review the Instance Tag section for more details.
Command: Is always required. Review the Command section for more details.
Attribute: Is always required. Review the Attribute section for more details.
[Index]: Is shown in [Brackets] as may be required depending on the Attribute being referenced. If not required it should not be defined. Depending on the Attribute, it can be made up of one or more indexes. Please refer to the Index section for more details.
[Value]: Is shown in [Brackets] as may be required depending on the Command or Attribute being referenced. If not be required it should not be defined. The Value would not normally have spaces, if it does it can be defined in "double quotes". It can also be a numerical value. Please refer to the Value section for more details.
LF: A Line feed or Carriage Return is used to define the end of the command.
