A transmitter may be disabled for short periods of time by the NOC for service or troubleshooting. It may also be disabled if the user discontinues the satellite service. If this condition persists, it can only be corrected by requesting that the unit be enabled. 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. 4 The transmitter is not responding to commands sent from the receiver This condition indicates that something is not operating properly in the Receive/Transmit Unit configuration. Perform the following actions to attempt to recover from this condition: • Verify that the Indoor Receive and Transmit Units are securely connected with a 25-pin parallel cable. • Reset the IRU by unplugging the IRU power cord from the wall socket and then plugging the power cord back into the wall socket. This will reset the Indoor Receive and Transmit Units. This condition could also be caused if the power supply is faulty. If this condition cannot be resolved by following the steps listed above, then you may need to replace the power supply, the Receive/Transmit unit cable and/or the Transmit Unit. Chapter 3 • The User Interface 1031484-0001 Revision 2 Table 6: Transmit status (TxCode) messages and corrective actions 5 The transmitter is not locked to the 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 the 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 by going to the Receive Statistics page. This could also be caused by inclement weather. 7 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. 8 The transmitter is available This is the normal operational state and indicates that the transmitter is ready to transmit data. 9 The transmitter is adjusting for optimal network timing This condition typically occurs when the DW4020 is first commissioned 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 the software version to ensure that you can enjoy uninterrupted operation. If you do not use the DW4020 for a long period of time and miss the updates, you may need to contact Customer Care. 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 ...
