Context Dependencies
:SYSTem:PRESet clears the Error Queue.
The queue is cleared (emptied) on *CLS, power-on, or upon reading the last
error from the queue.
If the Error Queue overflows, the last error in the queue is replaced with the
error -350, "Queue overflow". Any time the queue overflows, the least recent
errors remain in the queue and the most recent error is discarded.
The maximum length of the Error Queue is 30.
This command switches the operation mode (primary or install) of the
Receiver.
Expanded Syntax
:SYSTem:LANGuage "INSTALL" or "PRIMARY".
Parameter
The “INSTALL” language is part of a highly-specialized set of features used to
erase the Receiver’s firmware, and to install a new firmware revision. It should
be selected only when firmware installation is required.
The “INSTALL” language offers the limited number of commands and queries
which are documented in this section. This set is designed to provide the
Receiver status and control capability required during firmware upgrade.
NOTE The SatStat program provides a Service menu which automates firmware
installation.
The “PRIMARY” language provides the capabilities required for normal
Receiver operation. If the “INSTALL” language has been selected as part of the
firmware upgrade, the “PRIMARY” language should be selected after the
upgrade to restore normal operation.
