Recovering From A Temperature Status Error; Mitigating High Receiver Temperature; Monitoring The Receiver Temperature - Novatel SMART7 Installation And Operation Manual

Chapter 8 Troubleshooting
To determine the cause of the error, log the RXSTATUS log and check the Receiver Error word.
If Bit 9 is set, it is a Temperature Status error. For information about reading the Error Word,
refer to Error Word on page 78.

8.3.2 Recovering from a Temperature Status Error

The receiver must be reset or power cycled to recover from a receiver error such as a Tem-
perature Status error.
Log information is lost when the receiver is reset. Therefore, any logs required to identify and
troubleshoot the error, such as the RXSTATUS log, should be collected before resetting the
receiver.
Also, steps should be taken to reduce the cause of the receiver temperature error to prevent the
error from occurring again. See Mitigating High Receiver Temperature below.

8.3.3 Mitigating High Receiver Temperature

If the receiver has a high temperature warning or error, use one or more of the following sug-
gestions to reduce the receiver temperature.
If possible, reduce the ambient temperature around the receiver or move the receiver to an
l
area with a lower ambient temperature.
Disable the receiver features that are not required for the current operation of the receiver.

8.3.4 Monitoring the Receiver Temperature

If the receiver is operating in a high ambient temperature environment, you can monitor the
receiver temperature using the RXSTATUS and HWMONITOR logs.
1. Log the RXSTATUS log and check Bit 1 of the Receiver Status word.

For information about reading the Receiver Status word, refer to Status Word on page 77.
2. If Bit 1 is 0, the temperature is okay. Continue monitoring, but no action is required.
If Bit 1 is 1, the receiver temperature has exceeded the warning limit.
3. Log the HWMONITOR log and check the two temperature status fields (0x01 and 0x16).
