Table 7: Receive code (RxCode) messages and corrective actions
3 | The receiver is not locked to a signal | If the DW4020 had been operating previously, this status is |
|
| probably due to inclement weather conditions and will be |
|
| corrected when the weather improves. This condition can also |
|
| indicate that the IRU 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 at the user location, a NOC |
|
| outage due to inclement weather or other reasons, a misaligned or |
|
| faulty antenna, or faulty cabling. If this keeps happening under |
|
| normal weather conditions, make sure the power supply is correct. |
|
| The power supply should be Part # |
|
| supply is correct, try |
|
| power cord from the wall outlet and then plugging it 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. Only when the receiver is in this state will the |
|
| transmitter operate correctly. |
|
|
|
6 | The receiver is not detecting a signal | This condition occurs when the IRU 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 |
|
| DW4020. Also, make sure that the power supply is correct. The |
|
| power supply should be Part # |
|
| the DW4020 by unplugging the power cord from the wall outlet |
|
| and then plugging it back in. |
|
|
|
7 | The receiver is locked to an unknown | This condition should only be seen during installation and occurs |
| network | 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 |
|
| The latter requires an antenna repointing. |
