2.6.2.3 Location Value 2
The DTA supports Location Value in the CVT of 2 (two). The DTA will attempt to tune to the frequency indicated
in the Frequency Vector field in the CVT with the Modulation Type provided. Once locked on, the DTA will
attempt to find the Program Number listed in the CVT and find the PID value for that program. The DTA will only
accept modulation types of 1 or 2; it will ignore the CVT if the modulation type of not 1 or 2. Failure to lock to the
frequency or acquire the PID after three attempts will result in the DTA reverting back to the previous operating
mode.
2.6.3 Code Object Delivery
The code object is delivered on an in-band FAT channel data carousel as specified in [Ref 1]. Evolution Digital will
provide the binary file necessary to perform the code download. The operator is responsible for creating the
carousel and CVT.
2.6.4 Code Download Retry
The DTA will attempt to download or validate the new image a total of three times. If after three attempts of trying
to download or validate code, the DTA fails, the DTA will return to the previous operating mode.
2.6.4.1 Failed Code Downloads
In the event the DTA fails to take the code download, the DTA will populate an appropriate message into the Code
Download Diagnostic Screen. Figure 18 and Figure 19 show examples of the Code Download diagnostic screen
when there is a code download failure. In Figure 18, the failure is due to the DTA not being able to locate the code
image on the QAM. Note that the DTA attempted to download the code one time but failed. This is shown by the
Validation Failure Count equaling one (1).
