Error flags are divided into WARNING and FATAL errors. FATAL errors
cause the PROLOGGER to stop operating and revert to sleep mode.
WARNING errors are for information only.
To wake a logger from sleep mode the logger must be connected to a
computer and the RTS signal presented. This powers on the logger but does
not allow signal scanning or log programs to run, however normal RS-232
communications can occur after the prompt (*CR).
A logger RESET will also set the logger from “sleep” to operating state.
