IRD Troubleshooting
The IRD that was provided with your satellite television service
may also be the cause of less-than-ideal operation.
4.2.1 IRD Data Port or Cable/Wiring
Refer to
Section 2.4.1, “Connecting the Antenna Unit Data Cable to
the IRD”
and your IRD user manual to confirm that the IRD is
properly connected to the Antenna Unit and the television.
4.2.2 AC Power Fluctuating
If the system periodically displays a picture for less than one
minute, then enters Search Mode 1, the IRD data port may be
locked up as the result of power fluctuations and will require a
reset. This can be verified by hooking up a PC to the data port
and checking for error messages. Reset must be done by:
1. Completely shutting down DC power to the
antenna.
2. Remove the AC source, either at the breaker or by
unplugging the IRD.
3. Wait at least 10 seconds before restoring power
first to the IRD and then to the antenna.
4.2.3 EchoStar IRD Commissioning Check
If you have purchased a DISH Network system, there is a chance
that your EchoStar IRD will fail to acquire the satellite when you
first activate it. This has been known to happen in IRDs that have
not been commissioned within several months of their
manufacture.
Appendix D
provides the manual satellite
acquisition and commissioning procedure.
4.2.4 Failed IRD Status Check
As detailed in
Appendix E
, TracVision SA completes a detailed
startup routine whenever it is turned on. One of the first checks
is the IRD status test. As noted in the typical startup cycles, the
expectation is that the IRD and its communications link to
TracVision SA will pass this test. There are, however, two
alternate results, each indicating a slightly different problem.

Troubleshooting
54-0149 Rev. B
The long-term fix, typically done at
original system installation, is to
install an Uninterruptible Power
Supply (like those available for use
with computer systems) on the IRD.
Be sure to specify a UPS with
adequate available current for all
devices attached to it. (An IRD
draws approximately 200 watts.)
