7 Internal data logger
Function and operation of the internal data logger
The uSonic-2 provides an internal data logger. The internal data logger is a first-
in/first-out- organized data logger.
The capacity depends on the variant of the uSonic-2.
If the data logger is activated by LD=1, the datasets won’t be displayed at the
serial interface and will be stored in the internal data logger.
If the capacity of the data logger is exhausted, the oldest datasets will be
overwritten.
The stored datasets can be read out with the following commands via the serial
interface:
Logger start / stop:
LD=0 Stop logging The datasets will be displayed at the serial
interface and not be stored in the internal
data logger.
LD=1 Start logging The dataset will now be stored in the
internal data logger and not displayed at
the serial interface.
LD=2 Start logging The dataset will now be stored in the
internal data logger and also displayed at
the serial interface.
(See also p. 46, LD- command)
Read out logger:
RL Read Log RL displays the oldest, unread dataset of
the internal data logger and marks this
dataset as read. RL is allowed only if LD=1.
The command RL has to be repeated as often as all datasets are marked as
read. If all datasets are read the message “end of log” will appear.
