6.1.2 Special pin description
For the IO lines that can work as input or output the corresponding output of this pin
has to be set to high (with PFAL command “
has to be set to high (with PFAL command “
$PFAL,IO
4
.Set=high”
), otherwise 0V will be
measured
(and the device could be damaged).
6.1.2.1 Analog input (6)
Analog voltage up to 35.0 V with 10 bit resolution can be processed and
remotely evaluated by a server application. Pull-up resistor to a constant input
voltage allows for resistive transducers to ground, e.g. fuel sensor or thermistors.
Because the pin 6 can operate either as digital or analog, it has to be
remotely evaluated by a server application. Pull-up resistor to a constant input
voltage allows for resistive transducers to ground, e.g. fuel sensor or thermistors.
Because the pin 6 can operate either as digital or analog, it has to be
configured and calibrated for such purposes before using.
To use these IOs as analog inputs, the following configuration is required in the
software.
To use these IOs as analog inputs, the following configuration is required in the
software.
PFAL,IO
0
.Config=AI,2,11
PFAL,IO
0
.Config=DI,3,6
where 0 is the index corresponding to IO1 (pin 6). The strings AI and DI are identifiers
for analog and digital input respectively. While the value after strings e.g. 3 and 6 are
min. and max. voltages that will be used to generate Low and High events respectively.

6.1.2.1.1Connection example using IO1 as analog inputs:
This pin can be connected to a temperature sensor (a NTC resistor for instance).
Therefore, you can set a low and high temperature alarm. Passage through
these thresholds will trigger an alarm. As alarm type you can use an SMS or a
TCP with GPIOP as attachment protocol. The SMS contents can be sent to a
mobile phone. An application example is shown in figure below:
