combination with several operating modes: for a secure data transmission, CMAC2
for integrity protection and CTR3 for encryption. Each LoRaWAN®device is person-

14 WIKA operating instructions WIKA-radio unit, model Netris®1
14614412.01 07/2023 EN/DE
EN
alised with a unique 128-bit AES key (AppKey) and a globally unique identifier
(EUI-64-based DevEUI), both used during the device authentication process.
→Further details can be found in the official LoRaWAN®Security White Paper from the
LoRa Alliance®, see https://lora-alliance.org
Bluetooth®Low Energy
Bluetooth®Low Energy communicates in the licence-free 2.4 GHz ISM band and is a
globally harmonised energy-efficient radio standard. Bluetooth®Low Energy uses 40
channels between 2.402 GHz and 2.480 GHz. Encryption is performed using the AES
128 encryption algorithm in combination with distributed key replacement.
The radio unit transmits the measured value as an optional broadcast message on the
advertising channels 37, 38 and 39, in addition to the instrument name and the battery
charge status. Further information and detailed configuration and command options are
available via a point-to-point connection.
Pairing is established using a passkey entry method and requires the entry
of a security code. Instrument settings can only be accessed after pairing
has been completed.The pairing key is set individually for each instru-
ment and is made available to the customer with the quick start guide. For
individual applications, the pairing key can be configured by the user via the
app.
If the security code is entered incorrectly 5 times, the instrument is blocked
for connection with this code. After disconnecting the voltage supply or
removing the battery, 5 attempts are once again available. If this is not
possible for technical reasons, e.g. because the sensor cannot be reached
to open the case, contact technical support.

Information on the installation of the receiving gateway
Position the gateway in such a way that the transmission power is optimally utilised. For
this, the following recommendations should be observed:
■Depending on the application, a gateway for indoor or outdoor use should be
selected.
■The radiation characteristics of the antenna should be taken into account when
positioning the gateway.
■If the sensors are located on one level, vertical mounting of the LoRaWAN®antenna
on the gateway is recommended.The location should ideally be in the middle of the
area to be covered.
■If the sensors are located on several levels, the gateway should be placed in the
middle of the building and the gateway antenna should be aligned horizontally.
■Another option is to place the gateway outside the building and align the antenna
vertically. In this way, a sufficient radio connection can be established from the
outside to several floors.
■In outdoor areas, ensure that the gateway is mounted at a sufficient height and is not
covered by anything in the immediate vicinity. The higher the gateway is positioned,
the further the LoRaWAN®connection reaches.

The temperature adjustment can be found in the “myWIKA wireless device” app under
“Device” / “Device actions” / “Temperature adjustment”.
The associated “password” is WIKA_Calibration!.
For RTD sensors (Pt100/Pt1000 2- /3-wire), adjustment values can be saved separately
in the radio unit:
1. Set the RTD sensors to be calibrated via “sensor measurements”.
2. Manual reset of “offset” and “gain” via “user calibration”. Reset “gain” to 1.0f
and “user calibration” “Offset” to 0.0f or reset the instrument to factory settings.
The user calibration is set at the factory and offers a high level of accuracy,
so calibration by the customer is not necessary.
Resetting the radio unit to the factory settings resets the settings for all RTD
variants (PT100/PT1000 2-/3-wire).
Two calibration points (P1 in K < P2 in K) must then be measured. In order to achieve a
high degree of accuracy, it is advisable to wait a short time until the measured value has
settled and to record this and the reference value.
The calculation of “offset” and “gain” will be carried out in accordance with the follow-
ing formulae:
Finally, the calculated values of “gain” and “offset” are entered and these are trans-
ferred to the radio unit using the “apply” button.
