4.1 Perms/Temps/Searching & Settings
The term "settings" is used throughout this document and includes the following set of
parameters:
Table 4.1: Settings Parameters for the Unity 550
The IRD is acting on one of three groups of settings at any given time, each of which is
described in
Table 4.2
Setting Description
Carrier The downlink frequency specified in MHz with up to two decimal places. This
value's absolute difference with the LNB LO frequency must be as specified in
main body of the Product Spec.
Data_rate Data rate is specified in Mbps with up to three decimal places. See the main body
of the Product Spec for the allowable range.
Fec_rate The inner FEC code ratio can have one of the values specified in the main body of
Product Spec.
Tag_site The Carrier ID "tag" with a value range of 0 through 15. The tag is text representing
the downlink carrier frequency in MHz. For multi-hop links, multiple tags are
embedded in the control stream and the selected value must correspond to the
particular downlink being received.
Note: Tag site 15 is a special entry. It means "receive this carrier without
requiring a matching carrier ID".
[program] This is the Program number, the identifier for a Program within the received
Transport stream. It must be a * wildcard or a number between 1 and 65535
inclusive. If the * wildcard is entered, the unit will select the first available program
in a program table contained with the Transport stream.
