Service Codes

Each element of the Service Code instruction is delimited by a single space. The commands are case sensitive and upper and lower case characters are used. The TTP string is structured in the following order:

Instance_Tag Service [Index] [Value] LF

Instance Tag: Is always required. Review the Instance Tag section for more details
Service: Is always required. Review the Service section for more details.
Index: Is shown in [Brackets] as may be required depending on the Service being referenced.
[Value]: Is shown in [Brackets] as may be required depending on the Command or Service being referenced. If not be required it should not be defined. Would not normally have spaces, if it does it can be defined in "Double Quotes". Can also be a numerical value. Refer to the Value section for more details.
LF: A Line feed or Carriage Return is used to define the end of the command.

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.

Status Indicator Reason Codes

Indicator reasons provide the user with more detail of indicators by way of text strings. It is possible for this list to change but has no functional effect on the amplifier product.

Reason Code	Text in GUI	Comment
1	PSU SAFEMODE	PSU is in safe mode
2	SENS FLT:DSP	There is no activity in voltage and current sense on any channel when power is ON
3	AUDIO FAULT	Deactivated Audio OK/ or missing audio clocks.
4	NEED SERVICE:1	The PSU did not get the PFC state OK signal after turning on the PFC in three attempts OR PFCStateOk has gone low during normal operation (HW error)
5	NEED SERVICE:2	The PSU did not get the DC state OK signal after turning on the DC/DC in three attempts OR DCStateOk has gone low during normal operation (HW error)
6	NEED SERVICE:3	The PFC output voltage did not reach the level where the DC/DC should be turned on within the required time
7	NEED SERVICE:4	Communication with DICO was lost
