The FEC for a potential signpost may be individually entered. After entering the FEC, the

new FEC along with the current frequency and symbol rate will be programmed into the

DVB receiver.

LK: ----, lock, LOCK

This field indicates the current lock status from the DVB receiver. “----“ indicates that the

DVB receiver currently has not established a lock on the programmed parameters. “lock”

indicates that the DVB receiver has initial lock on the data stream. “LOCK” indicates that it

has established a better lock indicating that it is able to estimate a bit error rate from the data

stream.

ID:

This field indicates the current text that the DVB receiver has pulled off of a data stream.

Prior to establishing a lock, the string “RCIx” will appear indicating that the DVB receiver is

trying to lock on the parameters defined by signpost # x. If any of the parameters have been

individually programmed the string will be “RCI;”.

When a lock is initially established, text such as “MPEG-2” may appear. This indicates that

the DVB receiver recognizes a data stream but has not pulled the orbital data information

from the stream.

A few seconds after lock is established, a string indicating orbital slot data should appear.

For example, “119W” will be extracted from data stream coming off of the EchoStar satellite

located at 119.0 West longitude.

NOTE: not all uplinkers will faithfully multiplex the orbital slot information into the data

stream. One of the main reasons this maintenance screen exists is to monitor if the orbital

slot information is being sent from a potential signpost.
