each time when pin 7 of connector X1 is tied to ground (triggered
auto-mode). The results of the measurements can be either read
from the transmit pin of the UART interface, or from the analog
outputs at connector X2.
NOTE: When the auto-mode is activated, the receive pin of the
UART interface has no function. The module will not respond to
any command sent to it.
The basic idea behind the auto-mode is that a fully configured and
calibrated module can be operated without the need of complex
communication protocols. However, the configuration (including
the configuration of the auto-mode!) and the calibration data have
to be adjusted in the full-control mode (or by using the USB-
interface cable in combination with the comfortable windows
software
Pyro Oxygen Logger ; please refer to the next chapter).
The communication protocol offers a special command for storing
the current configuration and calibration data permanently in the
internal flash memory. Thus, a fully configured module can be
operated in auto-mode even if the power supply is intermediately
interrupted.
A typical application scenario would be the following: the
FireStingO2-Mini-ST could be configured and calibrated in a
"calibration lab" using the full-control mode (or the windows
software
Pyro Oxygen Logger ). The configuration and the
calibration data are stored in the internal flash memory. Then the
sensor is brought to the "field application" which can be a remote
place. By connecting pin 6 of the connector X1 to ground the
module starts measuring without the need of any UART
communication. The measurement results can be read out from
the analog output (or from a text-string sent via the UART transmit
line).
