text-command via the UART interface. The measurement results
can be either read out via the same UART interface. Alternatively,
measurement results can be also read from the analog output.
For further details please refer to the separately available
communication protocol.
5.2 Auto-Mode
In the full-control mode each single measurement has to be
triggered by a specific command sent via the UART interface (e.g.
the MSR- or TMP-commands for measuring oxygen or
temperature, respectively). Alternatively, an auto-mode can be
activated by connecting pin 6 of connector X1 to ground (Fig. 5).

The auto-mode offers the possibility, (i) that the measurements
are automatically triggered periodically by an internal timer
(interval auto-mode) or (ii) that the measurements are triggered
