Knowledge Base - DW7000 Rx/Tx Codes

Hughes DW7000 units use a numbered code system to describe the state of the transmitter and receiver functions. These codes can be found on the System Status page. Below is a list of all codes in use. DW7000 codes use the same numbering scheme as other DirecWay hardware, but may not use some codes and have minor differences in debugging steps because of the different hardware. For information on how to find these codes, see the troubleshooting guide for your unit.

Rx Codes:

Code	Description	Comments
1	The receiver is in pointing mode.	This condition indicates that the installer is performing antenna pointing. In this mode, the transmitter is disabled for safety reasons since the installer is working near the dish. If this occurs during normal operation, try power-cycling the DW7000 by unplugging the power cord from the wall outlet and then plugging it back in.
2	The receiver is in factory or NOC mode.	This status is for DW7000 testing purposes only and should never be seen by users. If this occurs during normal operation, try power-cycling the DW7000 by unplugging the power cord from the wall outlet and then plugging it back in.
3	The receiver is not locked.	If the DW7000 had been operating previously, this status is probably due to inclement weather conditions and will be corrected when the weather improves. This condition indicates that the Receiver is unable to receive the signal from the NOC. This is also associated with a signal level less than 30. This occurs if there is a weather outage for the user, a NOC outage, a misaligned or faulty antenna, or faulty cabling. If this keeps happening under normal weather conditions, make sure the power supply to the DW7000 is correct. The power supply should be Part # 1031105-0001. If the power supply is correct, try power-cycling the DW7000 by unplugging the power cords from the wall outlet and then plugging them back in.
4	The receiver is locked to the wrong network.	This condition should only be seen during installation and occurs when the receiver is locked to a signal, but the signal ID does not match the ID that was assigned to the user during commissioning or the ID that was entered by the installer during manual pointing. If this occurs during normal operation, it may be due to the user changing acquisition parameters, including frequency and/or location of satellite, or the antenna becoming misaligned.
5	The receiver is operational.	This is the normal operating state where the receiver is receiving data from the NOC. This is the only state when the transmitter will operate correctly.
6	The receiver is not detecting any signal.	This condition occurs when the Receiver is not detecting any type of radio signal from the antenna. This could indicate that the cabling between the receiver and the antenna is faulty or that the receiver itself is faulty. Check that the cables are firmly connected on the DW7000. Also, make sure that the power supply to the DW7000 is correct. The power supply should be Part # 1031105-0001. Try power-cycling the DW7000 by unplugging the power cords from the wall outlet and then plugging them back in.
7	The receiver is locked to an unknown network.	This condition should only be seen during installation and occurs when the receiver is locked to a signal but there is no DIRECWAY Network ID on that signal. If this occurs during pointing or commissioning, the antenna has not been pointed correctly. If it occurs during normal operation, it may be due to the user changing acquisition parameters, including frequency and/or location of satellite, or the antenna becoming misaligned. The former condition can be corrected by re-commissioning the site. The latter requires an antenna repointing.

Tx Codes:

Code	Description	Comments
1	The transmitter has been disabled by the Network Operations Center.	This condition occurs when the transmitter is not enabled. A transmitter may be disabled for short periods of time by the NOC for service troubleshooting. It may also be disabled if the user discontinues the satellite service. The most common reason to see Tx Code 1 is that the site has been suspended for virus activity. To restore service, contact technical support.
2	The transmitter has been placed in test mode by the Network Operations Center.	This status requires no user action and this test usually completes in 15 minutes or less. This condition occurs when the NOC places the transmitter into special transmission modes to measure the performance of the transmitter. When in this mode, the unit is unable to transmit normal user data to the NOC.
3	The transmitter is locking to the receive carrier.	This condition occurs during initial startup or when the receiver is locking to the receive signal. It is normal for this condition to persist for up to 10 seconds. If this condition persists for more than 10 seconds, try disconnecting and reconnecting the receiver coaxial cable and wait 10 seconds. If the situation still persists, then the Indoor Transmit unit may need to be replaced.
5	The transmitter is not locked to network timing.	No action is necessary if this condition occurs from time to time and quickly resolves itself. If this issue persists, it is likely due to a NOC-related service issue. The condition may also be due to Indoor Transmit Unit failure. In rare cases, the Transmit unit may fail and may have to be replaced.
6	The transmitter is not available because the receiver is not detecting a signal or is not locked to the correct network.	Check your receive signal. This condition occurs when the Indoor Receive Unit is not receiving a good signal. The receiver must be locked to the correct network in order for the transmitter to operate. If your receiver is not locked (no signal) or is locked to the wrong network, the transmitter is unable to transmit data. Please verify that you have a good signal strength.
7	The transmitter is not available because the receiver is not tuned for normal operation.	This condition occurs when the transmitter is disabled for safety reasons. This should only be seen during installation or antenna pointing.
8	Transmitter available for Normal Operation.	This is the normal operational state and indicates that the transmitter is ready to send data. This state can only be reached when the Rx Code is 5. If you have an abnormal Tx Code, start troubleshooting with the Rx Code first.
9	The satellite transmitter is adjusting for optimal network timing.	This condition typically occurs when your DW7000 is first commissioned, is being ranged, or the first time it is used for data traffic. This must occur before the Indoor Transmit Unit is able to transmit successfully. Typically, this process usually takes less than a minute.
10	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 return channel equipment failures in the NOC.
11	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 your software version to ensure that you can enjoy uninterrupted operation. If you keep the DW7000 down for a long period of time and miss the updates, you may need to contact technical support.
12	The transmitter is not receiving network control messages from the Network Operations Center.	This condition indicates a NOC equipment outage. This may be a transient condition and the system should recover automatically.
13	The transmitter is unable to range because it cannot communicate with the Network Operations Center.	Ranging is the process that adjusts your satellite transmitter timing and power. Your 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 the wrong zip code or latitude/longitude information was entered during installation. The outdoor transmitter unit (ODU) is not operating properly or is not properly connected to the ITU. Please ensure that the transmit cable is securely fastened to the Transmit Unit.
14	The transmitter is not available because ranging has failed.	Ranging is the process that adjusts your satellite transmitter timing and power. Your satellite transmitter conducts ranging as needed to ensure that it can communicate successfully with the Network Operations Center. This condition indicates that the transmitter is not operational because ranging has failed. This may happen due to the antenna becoming misaligned or if repeated attempts to range do not succeed. This condition may also be caused due to adverse weather conditions. In rare cases, this may also indicate NOC issues but should clear within a few minutes. If your system was operational in the past and you see these messages repeatedly, you can try to force range by performing the Connectivity Test in the DW7000 web interface.
15	The transmitter is waiting for a ranging request to be processed by the Network Operations Center.	This condition occurs if the system is busy adjusting power and timing for other users. This process may take up to a minute or more.
16	The transmitter is waiting for a transmit request to be processed by the Network Operations Center.	This condition occurs when the system is unable to provide transmit bandwidth. This occurs when many users sign-on simultaneously. It should clear in a few minutes automatically.
17	The transmitter is unable to obtain an available transmission rate.	This condition occurs if the transmitter cannot successfully range. Ranging is the process that adjusts your satellite transmitter timing and power. Your satellite transmitter conducts ranging as needed to ensure that it can communicate successfully with the Network Operations Center. Possible causes are: The transmitter could not achieve enough power to transmit. This is likely caused by an installation problem where the antenna is not accurately pointed or it maybe a transmitter power problem. Check the power supply and make sure that it is Part # 1031105-0001.
18	The transmitter is requesting a transmit pointing test.	This condition can occur during installation when the Antenna Pointing program on the installation computer requests that the transmitter perform a transmit pointing test. This condition persists until the NOC responds that the transmitter is either actively performing the pointing test or is queued to perform the test when test resources become available in the NOC. This is a normal condition for initial installation. The transmitter may also periodically go into this condition for short periods of time (less than 5 seconds) to perform periodic transmit pointing tests. These periodic tests are performed to ensure that the antenna is pointed accurately.
19	The transmitter is queued for a transmit pointing test.	This condition can occur during installation when the Antenna Pointing software on the installation computer requests a transmit pointing test and the NOC has responded that the transmitter is queued for the next available test time. It may also occur when the transmitter is performing periodic background transmit pointing tests at the same time that other users on the network have requested tests. This is a normal state after initial installation.
20	The transmitter is performing a transmit pointing test.	This condition occurs when one of the following tests are active: During installation, the Antenna Pointing software requests that the transmitter perform a transmit pointing test. This condition will persist until the Antenna Pointing software exits from the transmit pointing test mode. The DW7000 performs a periodic background transmit pointing test to make sure that the antenna has not got misaligned. This periodic test takes less than 5 seconds. If the problem persists, try power-cycling the DW7000 by unplugging the wall outlet and plugging it back in.
21	The transmitter is disabled because a transmit pointing test failed.	This condition occurs when the transmitter fails a transmit pointing test. This indicates that the transmitter did not meet the minimum specifications required. This is likely due to an antenna installation problem. The antenna installer needs to fine-point the antenna. The transmitter will not transmit until the transmit pointing test passes.
22	The transmitter is disabled because a transmit pointing test cannot be performed	This condition occurs when the transmitter cannot perform the transmit pointing test when initially installed or when the transmitter is required to range. The condition indicate that the NOC components needed to perform the transmit pointing test are not operational.
23	The transmitter is disabled because a transmit pointing test cannot be performed	This condition occurs when the transmitter is required to perform a periodic background transmit pointing test, but has not been able to perform the test within the time window required. The transmitter is expected to be in this condition for no more than two minutes at random periodic intervals. This condition can occur after the transmitter is first powered on after it has been powered off for more than a day. If the unit remains in this condition for more than two minutes, then the automated transmit pointing components in the NOC are likely experiencing problems. This condition should clear in a few minutes.
24	The transmit cable is not connected	This condition occurs if the DIRECWAY unit is not able to detect the transmit cable connection. Please check your transmit cable and make sure it is securely connected. This condition can also occur if the transmit cable is not connected to the Antenna or if either the cable or the Antenna is damaged.
