Note:
Input power and reflected power are not monitored.
Data requests will be serviced with the HPA in either ‘local’ or ‘remote’ mode.
However, for other commands to be executed, (with the exception of ‘remote
enable’) the HPA must be in ‘remote’ mode. Commands will be rejected as
unexecutable with the HPA in ‘local’ mode.
