4.2.4 Failed IRD Status Check
As detailed in
Appendix E
, TracVision Cruiser 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 Cruiser will pass this test.
There are, however, two alternate results, each indicating a
slightly different problem.
Test Result: NONE
If the system tests achieves a result of
NONE
, there is no
communication at all between the antenna unit and the IRD.
Solution
Check to be certain the IRD and TracVision Cruiser are
both connected properly at the low-speed data port. Refer to
Section 2.4, “Connecting the Antenna Unit,”
for correct Antenna
Unit to IRD wiring procedures and diagrams. After verifying
the connection, cycle the power on and off and review the
startup test results.
This may also be caused if the high-speed data port on an
EchoStar IRD is not enabled. See
Appendix D
for instructions on
enabling the EchoStar high-speed data port.
Test Result: UNKNOWN
In the instance of a result of
UNKNOWN
, a communications
link exists, but the data received by the antenna unit is garbled
and unrecognizable.
Solution
As with a result of
NONE
, first check to be certain the IRD and
TracVision Cruiser are connected properly at the low-speed
data port. Refer to
Section 2.4, “Connecting the Antenna Unit,”
for correct Antenna Unit to IRD wiring procedures and
diagrams. After verifying the connection, cycle the power on
and off and review the startup test results. If this does not
initially succeed, refer to
Section 2.5, “Connecting the IRD to
Vessel Power”
and follow the IRD reset procedure.
