Open-Collector Hardware Output - TFA KlimaLogg Pro Mode D'emploi

If the synchronization is successful, another beep sounds and the USB
symbol is displayed steadily. The KlimaLogg Pro starts to transfer his
datas to the PC.
Initiate contact:
Synchronization is only required once in order to assign the logger to the
software. In order to initiate contact to the software during the next start,
it is only necessary to press the USB button once. The KlimaLogg Pro
then attempts to establish the connection for 5 seconds and displays the
assignment received from the software on the text display.
For information about the operating of the PC software, we recommend
that you use the manual (which is available as PDF file at the installation
folder of the software) or use the help function in the PC software.
Note:
The data sets that have been recorded are wirelessly transferred to the
PC using the USB transceiver. The average transfer speed is 20 data
sets per second. In extreme cases, it can take almost 45 minutes until all
data sets have been downloaded (when the memory is completely filled).
During radio-clock reception, communication with the USB receiver is not
possible and is interrupted. When reception is successful,
communication is automatically restored again.
OPEN COLLECTOR HARDWARE OUTPUT:
The KlimaLogg Pro has an open collector hardware output.
This output has two switching outputs that react as follows in case of an
alarm on channel 1.
Switch point 1, active when the temp. or rH is exceeded on channel 1.
Switch point 2, active when the temp. or rH is undershot on channel 1.
A switch point is active as long as the alarm limit is triggered and
deactivated again as soon as the respective value is again within the
standard range or the respective alarm setting is deactivated.
The open collector output has a jack for a 3.5 mm jack plug. The
following drawing shows the configuration.
