Figure 37 – “Direct Tune” Interface on Advanced Edit page

This section gives you a method to force a tuner to a particular satellite and transponder pair.

This ability can especially useful when attempting to track and isolate RF problems with the

COM1000 system. The data required to perform this operation can be gathered from the basic

“Tune” interface shown in Figure 34 above. A brief explanation of each field follows.

Network_ID – This field displays the DIRECTV network of the currently tuned channel. This

number correlates to a specific satellite, and can be used in conjunction with the

“Frequency_Index” field below to determine whether the card is locked to the correct channel

version (as of this version of the manual, all SD content resides on Network 0, and the HD

content is spread across Networks 10 and 15).

Frequency_Index – This field displays the DIRECTV frequency index of the currently tuned

channel. This number correlates to a specific transponder, and can be used in conjunction with

the “Network_ID” field above to determine whether the card is locked to the correct channel.
