7.5 Parameters Overview
Term definition
Probe ID
The probe ID is an unmistakable ID with max. 5 characters which is recognized by the receiver.
The ID can be individually changed, for example, to achieve a better overview of a system.
However, ensure that an ID is only assigned once within the reception range to avoid malfunc-
tions.
Transmission interval
This parameter is used to define the time intervals used to transmit data to a receiver. The set-
ting of the "Transmission interval" parameter affects the battery service life. For this reason, act
with caution and do not only consider the transmission quality when selecting the interval.
Transmission frequency
The transmission frequency defines the frequency band used to transmit data to a receiver. The
transmission frequency is determined to 868.4 MHz in Europe because special regulations are
determined for the ISM band (Industrial-Scientific-Medical-Band) concerning transmission in-
terval and transmission capacity.
In the 915 MHz frequency band, it is possible to select between frequencies.

TIP!
At a transmission interval of > 15 s, the probe transmits a so-called Link telegram, i. e. the
telegrams are transmitted at the factory-set intervals for a period of 30 minutes, afterwards at
the set transmission interval.
TIP!
If the setup plug is connected, the probe automatically transmits telegrams with a transmis-
sion interval of 1 s to enable the receiver to detect changes. After the setup connector is re-
moved, the telegrams are transmitted again at the set transmission interval.
