ADVField/Hydra Operation Manual (September 1, 2001) 23
• When turned on or off, many computers and data loggers send a signal out the serial port that
can be interpreted as a
BREAK
. If the ADV is connected to the serial port, this can interrupt data
collection or bring the ADV out of sleep mode. This may cause a loss of data or drain the bat-
teries. Always disconnect the ADV from the computer or data logger before turning it on/off.
• The ADV has an “accidental
BREAK
protection” feature. If the system was in data acquisition
mode or deployment mode, and a
BREAK
(or
+++
) is received (either manually or through elec-
tronic noise), the system will resume data collection unless a valid command is received with-
in the ensuing five-minute interval.
