Chapter 6 Troubleshooting
6.3 High Temperature Environments
The operating temperature of SMART2 increases as more features (channels used, HDR mode, etc.) are
enabled.
When the receiver is operating in an environment that is near its maximum ambient temperature, an increase in
the ambient air temperature or enabling additional features may cause the receiver to exceed its maximum oper-
ating temperature and generate a Temperature Status error. When a Temperature Status error occurs, the
receiver idles all channels, turns off the antenna and disables the RF hardware. The communication interfaces
continue to function so commands can be sent and logs received.
6.3.1 Indicators of an Error State
The indications that the receiver is in an error state, such as a Temperature Status error, are:
Logs that have a solution status will show INSUFFICIENT_OBS as the Solution Status.
l
The RXSTATUSEVENT log is output on all communication ports. This log will indicate an error condition in
l
the Receiver Error word of the log.
All logs output have Bit 0 set in the Receiver Status word of the log header.
l
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 41.
6.3.2 Recovering from a Temperature Status Error
The receiver must be reset or power cycled to recover from a receiver error such as a Temperature 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 occur-
ring again. See Mitigating High Receiver Temperature below.
6.3.3 Mitigating High Receiver Temperature
If the receiver has a high temperature warning or error, use one or more of the following suggestions to reduce the
receiver temperature.
If possible, reduce the ambient temperature around the receiver or move the receiver to an area with a lower
l
ambient temperature.
Disable the receiver features that are not required for the current operation of the receiver.
l
6.3.4 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.
