1033295-0001 Revision A

The transmitter is not available
because the satellite receiver
is not tuned for normal
operation

This condition occurs when the transmitter is disabled for
safety reasons. If this happens during installation or
commissioning, the installer will close the Antenna Pointing
program and resolve the condition.

The transmitter is available

This is the normal operational state and indicates that the
transmitter is ready to transmit data.

The transmitter is adjusting for
optimal network timing

This condition typically occurs when the DW6000 is first
commissioned or the first time it is used for data traffic. This
must occur before the DW6000 is able to transmit
successfully. Typically, this process usually takes less than a
minute.

The transmitter is unable to
communicate with the Network
Operations Center

This condition indicates that the unit has stopped attempting
to transmit user data because there were a number of failures
in sending data to the NOC over the satellite link. This could
be the result of weather conditions causing lost packets or,
rarely, return channel equipment failures in the NOC.

The transmitter is not available
because the receiver software
is out of date

This condition indicates that the installed software version is
not recent enough to operate on the network. New software
will be required from time to time due to network infrastructure
and capability upgrades and in order to maintain network
efficiency and fix any known problems.The system will
automatically update the software version to ensure that you
can enjoy uninterrupted operation. If you do not use the
DW6000 for a long period of time and miss the updates, you
may need to contact your service provider.

The transmitter is not
receiving network control
messages from the Network
Operations Center

This condition indicates a NOC equipment outage. This
should be a transient condition and the system should
recover automatically.

The transmitter is unable to
range because it cannot
communicate with the Network
Operations Center

Ranging is the process that adjusts the satellite transmitter
timing and power. The satellite transmitter conducts ranging
as needed to ensure that it can communicate successfully
with the Network Operations Center. This condition can
indicate any of the following:
• The NOC is not receiving ranging information from the

transmitter. This may indicate a transmit problem at the
NOC. This should get cleared in a few minutes.

• The transmitter is unable to achieve enough transmit power

to send ranging information to the NOC. Make sure that the
power supply is correct. The power supply should be Part
#1031105-0001.

• The transmitter is sending incorrect timing data because

incorrect ZIP code or incorrect latitude/longitude
information was entered during installation.

• The outdoor transmitter unit (ODU)--that is, the antenna--is

not operating properly or is not properly connected to the
DW6000. Please ensure that the transmit cable is securely
fastened to the satellite out connector.
