Section 4. Interpreting Screen Displays
The IDR V1000 screens provide detailed information on the status of the receiver, the
satellite signal, the received data, and the output ports. This section describes how to
interpret the screen information to troubleshoot problems or to monitor IDR V1000
status. The descriptions of the screens are organized in the order of the
troubleshooting steps listed in Table 4-1.
If you need additional background information or definition of terms, refer to Section
5 and the Glossary
Identifying
Problem
Indications
The first indications of a problem typically show up as missing or damaged data on
the end user’s display monitor:
•
Data was being passed to the monitor and suddenly stops for extended periods
•
Data isn’t being displayed in the expected format
•
Data is garbled or pieces of data are missing
Table 4-1. Screens Related to Troubleshooting Steps
Step
Check These Basics:
Refer to these screens:
1
Verify cables (output, coaxial, and power) are
connected.
Not applicable
2
Make sure the IDR V1000 is receiving data.
•
Check the quality of the signal
•
Check for indications of errors in
transmissions
Show status
•
Superscreen
•
Demodulator screen (AGC
and EbNo readings)
•
TDD screen (CTL CH)
3
Check the output port to see that data is
getting through
•
Check data buffering in logical receiver
•
Check flow control at output port
Show status
•
Serial port status
•
Session activity
Diagnostics
•
Test serial port output
NOTE: The structure of the screen displays— the order in which screens are
accessed, the position of the fields, as well as the contents of some of the
fields—stays the same, even when the type of received data may affect some
of the interpretations.
Statistically-multiplexed data requires, and yields, more processing
information, much of which is captured within the screen displays. The
other data types, transparent asynchronous and transparent synchronous,
are handled differently at both ends and generate different types of status.
Different field interpretations are noted here if they vary depending on the
type of data being handled.
