***) is also valid for WS502-UMB, WS503-UMB, WS504-UMB, WS510-UMB
Sensors marked (ext) in the table are additional accessories and not included with the
device. The table shows which external sensors can be connected to the different models.
Note: The external temperature sensor and the external rain gauge use the same input, so
only one of them can be connected simultaneously.
Attention: Please note that, due to the approval of the radar sensor used, there are different
country options on equipment which includes precipitation measurement by radar
technology.
The equipment is connected by way of an 8 pole screw connector and associated
connection cable (length 10m).
The measured values are requested over the RS485 interface in accordance with UMB
protocol.
During commissioning, configuration and measurement polling takes place using the UMB-
Config-Tool (Windows® PC software) or the ConfigTool.NET (for WS100-UMB)
4.1 Air Temperature and Humidity
Temperature is measured by way of a highly accurate NTC-resistor while humidity is
measured using a capacitive humidity sensor. In order to keep the effects of external
influences (e.g. solar radiation) as low as possible, these sensors are located in a ventilated
housing with radiation protection. In contrast to conventional non-ventilated sensors, this
allows significantly more accurate measurement during high radiation conditions.
WS100-UMB is not intended for air temperature measurement, so it is not equipped with a
radiation shield. Air temperature values with reduced accuracy are available as service
channels for additional information.
Additional variables such as dewpoint, absolute humidity and mixing ratio are calculated
from air temperature and relative humidity, taking account of air pressure.
Operating Manual Smart Weather Sensor
G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany 11
4.2 Air Pressure
Absolute air pressure is measured by way of a built-in sensor (MEMS). The relative air
pressure referenced to sea level is calculated using the barometric formula with the aid of
the local altitude, which is user-configurable on the equipment.
4.3 Precipitation
Tried and tested radar technology from the R2S-UMB sensor is used to measure
precipitation. The precipitation sensor works with a 24GHz Doppler radar, which measures
the drop speed and calculates precipitation quantity and type by correlating drop size and
speed.
WS401-UMB and WS601-UMB are using an unheated rain gauge for precipitation
measurement. This version can be recommended for low power application etc.
4.4 Wet Bulb Temperature
The wet bulb temperature is the temperature of a moist or icy surface exposed to air flow.
4.5 Specific Enthalpy
Parameter of state of the humid air, composed of the specific enthalpies (heat capacity) of
the components of the mixture and related to the mass fraction of the dry air (at 0°C).
4.6 Air Density
The air density indicates how much mass in a given volume of air is contained and it is
calculated from the measured values of air temperature, humidity and air pressure.
4.7 Wind
The wind meter uses 4 ultrasonic sensors which take cyclical measurements in all directions.
The resulting wind speed and direction are calculated from the measured run-time sound
differential. The sensor delivers a quality output signal indicating how many good readings
were taken during the measurement interval.
4.8 Compass
The integrated electronic compass can be used to check the north – south adjustment of the
sensor housing for wind direction measurement. It is also used to calculate the compass
corrected wind direction.
4.9 Heating
The precipitation sensor and wind meter are heated for operation in winter.
4.10 Global Radiation
The global radiation is measured by a pyranometer mounted in the top cover of the Smart
Weather Sensor.
4.11 Lightning Sensor
WS800-UMB includes lightning detection by an integrated sensor analysing the radio wave
emission of lightnings. It delivers a count of recognized lightnings.
The sensor analyses spectrum and wave form of the received signal to suppress the
detection of man made electrical discharges. Nevertheless false detections can not be totally
excluded specially in an environment with high power electrical equipment.
4.12 External Temperature Sensor
Optionally all models may be equipped with an external NTC temperature sensor for the
acquisition from additional measurement points. The type of NTC is the same as used for the
internal air temperature sensor.
External temperature sensor and external rain gauge can not be connected at the same
time.
Operating Manual Smart Weather Sensor
12 G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany
4.13 External Rain Gauge
Models without integrated precipitation acquisition can be equipped with an external rain
gauge.
External rain gauge and external temperature sensor can not be connected at the same
time.
4.14 (WS100-UMB only: ) Impulse Output for Rain Gauge Simulation
WS100-UMB provides a digital impulse output for simulation of a rain gauge. Depending on
configuration settings the output is pulsed once for each 1.0mm, 0.1mm or 0.01mm (default)
of precipitation.
If the WS100-UMB is configured for impulse output, the serial interface is not available for
communication in UMB or other serial protocols.

5 Generation of Measurements
5.1 Current Measurement (act)
In accordance with the specified sampling rate, the value of the last measurement is
transmitted when the current measurement value is requested. Each measurement is stored
in a circular buffer for the subsequent calculation of minimum, maximum and average
values.
5.2 Minimum and Maximum Values (min and max)
When requesting the minimum and maximum values, the corresponding value is calculated -
via the circular buffer at the interval (1 – 10 minutes) specified in the configuration - and
transmitted.
Note: In the case of wind direction, the minimum / maximum value indicates the direction at
which the minimum / maximum wind speed was measured.
5.3 Average Value (avg)
When requesting the average value, this is calculated - via the circular buffer at the interval
(1 – 10 minutes) specified in the configuration - and transmitted. In this way moving
averages can also be calculated.
For some values the standard deviation is calculated for the same interval. The calculation of
standard deviation will only be activated after the related UMB channel has been requested
for the first time.
5.4 Vectorial Average Value (vct)
In the specific case of wind measurement, measurements are calculated vectorially. To this
end, the average values of the vectors are generated internally. This calculation is performed
with the same configured interval time as that for the minimum, maximum and average
values. Hence the value (wind speed) and angle (wind direction) of the vector are calculated.
Note: On delivery, the interval for the calculation of minimum, maximum and average values
is set at 10 minutes. If necessary, this can be adjusted to the particular requirements (1 – 10
minutes) with the aid of the UMB-Config-Tool (see page 31).
Note: The evaluation of the standard deviation values is deactivated after power on of the
device. The function will be activated with the first request to any of the standard deviation
channels.
To get standard deviation values of the first integration period after power on a dummy
request to any one of the standard deviation channels should be inserted.

Note: The second measurements are averaged over 10 seconds for the output of the current
(act) measurement. The 'fast' channels deliver every second a value.
The minimum / maximum wind direction indicates the direction at which the minimum /
maximum wind speed was measured.
The corrected wind direction is calculated from the wind direction measured by the wind
sensor and the heading measured by the compass.
Optionally the compass correction of the wind direction can be activated for all wind direction
values. (Settings by UMB Config Tool)
Note: The correction function is designed for correction of the wind direction of a statically
mounted sensor. If the alignment of the sensor changes during the measurement (i.e. if the
sensor is mounted on a rotating platform or similar) the correction function will not in all
cases work properly, especially not for the vector average.
It is of course possible to use the correction function for mobile measurement units, where
the alignment is changed between measurement periods.
*) Note: The evaluation of the standard deviation values will be activated after the first
request of a standard deviation channel. Please see p. 11.

50% do not represent a general problem. If the value falls towards zero the measuring
system is reaching its limits.
If during critical ambient conditions the system is no longer able to conduct reliable

Note: Reliable operation of the compass is only possible, if the sensor has been mounted
according to the instructions in this manual, i.e. on top of the pole. Should the sensor be
mounted on a traverse, the distribution of iron masses will be different from the situation
during factory calibration. This may lead to additional deviation of the bearing. This also
applies to lightning rods mounted at the pole top!
Dependent on the location of the installation the local declination of the earth magnetic field
has to be considered. The declination value is entered using the UMB-Config-Tool (see page
34). The declination for the installation location can be found in the Internet, e.g. at
http://www-app3.gfz-potsdam.de/Declinationcalc/declinationcalc.html
http://www.ngdc.noaa.gov/geomagmodels/Declination.jsp
Note: When the fan is not rotating the compass measurement value will be influenced by the
magnetic field of the fan. Normally the compass measurement will be performed with the fan
rotating to compensate this influence. If, starting from device version 037, the fan will not be
switched on in case of low operating voltage (less than 12V) deviations of the compass
measurement value must be accepted.
Note: When the device is operated in Power Saving Mode 1 or 2 the compass measurement
is performed only once after power on. Later changes of the orientation of the device will not
be recognized.

Note: The device versions with radar technology (WS100-UMB, WS400-UMB, WS600-UMB,
WS700-UMB, WS800-UMB) calculate the precipitation intensity from the accumulated
precipitation differences of the last 6 minutes before the measurement data request.
The lower resolution of the rain gauge would lead to high fluctuation of the intensity values,
so the rain gauge versions (WS401-UMB and WS601-UMB), as well as the external rain
gauge, use the accumulated precipitation of the last 60 minutes prior to the current
measurement for intensity calculation.

Note: As the magnetic North Pole indicated by the compass differs from the Geographic
North Pole, account must be taken of the declination (variation) at the location when aligning
the sensor.
Depending on the location, the variation can be more than 15° (in North America for
example). In Central Europe the variation can be largely ignored at present (< 3°). You can
find further helpful information on this subject on the Internet.

7.3 Selecting the Installation Location
In order to guarantee long service life and correct equipment operation, please pay attention
to the following points when selecting the installation location.
7.3.1 General Instructions
Stable subsurface for installing the mast
Free access to the equipment for maintenance works
Reliable power supply for permanent operation
Good network coverage when transmitting over a mobile communications network
Note: The computed measurements specifically apply to the equipment location only. No
conclusions can be drawn with regard to the wider environment or a complete road section.
ATTENTION:
Only approved and tested appliances (conductors, risers etc.) should be used to install the
device on the mast.
All relevant regulations for working at this height must be observed.
The mast must be sized and anchored appropriately.
The mast must be earthed in accordance with regulations.
The corresponding safety regulations for working at road side and in the vicinity of the
road carriageway must be observed.
If the equipment is installed incorrectly
It may not function.
It may be permanently damaged.
Danger of injury may exist if the equipment is allowed to fall.
7.3.2 Sensors with Wind Measurement / Compass
Installation at the top of the mast
Installation height at least 2m above the ground
Free field around the sensor
Note: Buildings, bridges, embankments and trees may corrupt the wind measurement.
Equally, passing traffic may cause gusts which may influence the wind measurement.
Note: for accurate compass readings, an aluminium mast is recommended.
7.3.3 Sensors with Radar Precipitation Measurement
Installation on the top of the mast
Installation height at least 4.5m above the ground
Distance to road carriageway at least 10m
Distance from moving objects (e.g. trees, bushes and even bridges) at least 10m at the
height of the sensor
Note: Falling or moving objects, e.g. falling leaves or leaves blowing in the wind, may cause
false measurements and/or precipitation types.
Note: Strong wind can influence the accuracy of the precipitation measurement.
Note: When selecting the installation location please take care to position the device at a
suitable distance from other systems incorporating a 24GHz radar sensor, such as traffic
counting devices on overhead gantry signs. Otherwise cross effects and system
malfunctions may occur. In the final analysis, the distance to other measuring systems also
depends on their range of coverage and signal strength.

8.1 Supply Voltage
The supply voltage for the Smart Weather Sensor is 12 - 24V DC. The power supply unit
used must be approved for operation with equipment of protection class III (SELV).
Starting with device version 037 the Smart Weather Sensor has an extended supply voltage
range of 4 … 32V DC. Operation with a supply voltage of 24V is recommended. Limitations
apply in case of supply voltages lower than 12V (see below).
8.1.1 Limitations in 12V mode
If the heating is operated on 12V DC, account must be taken of the functional restrictions in
winter operation.
Note: A heating voltage of 24V DC is recommended to guarantee full heating duty.
8.1.2 Limitations in Case of Operation with Supply Voltage Below 12V
When operating a Smart Weather Sensor (device version >= 037) with supply voltages lower
than 12V DC, the fan will be not switched on, independent of the fan operating mode. This
may influence the accuracy of temperature and humidity measurement in case of solar
radiation.
Additionally deviations of the compass measurement values have to be accepted.
When operating the Smart Weather Sensor in Power Save Modes with supply voltages
below 12V the minimal supply voltage depends on the length of the connection cable.
The minimal permitted supply voltage (UBmin)can be approximately evaluated from the
equation:
UBmin = 4V + 0.3V (cable length / m)
The minimal supply voltage for a 10m cable is then UBmin = 6V. The influence of the cable
length on minimal supply voltage can be reduced by using of a cable with larger wire cross
section.
8.2 RS485 Interface
The equipment has an electrically isolated, half-duplex, 2 wire RS485 interface for
configuration, measurement polling and the firmware update.
See page 46 for technical details.

Warning: The heating voltage (red = positive heating voltage; blue = heating voltage
ground) is not connected to the ISOCON-UMB but wired direct to the power supply unit.
During installation please also refer to the operating manual for the ISOCON-UMB.
8.4 Use of Surge Protection (8379.USP)
When using surge protection (Order No.: 8379.USP), please pay attention to the connection
example in the surge protection operating instructions.
8.5 Connection of External Temperature and Precipitation Sensors
External sensors are to be connected to pins 5 and 6 of the plug connector, i.e. to the gray
and pink wires of the cable delivered with the Smart Weather Sensor.
The temperature sensors as well as the external rain gauge are unipolar, so any connection
sequence can be chosen.
The type of external sensor has to be set using the UMB Config Tool.
For details please refer to Chapter18.
8.6 (WS100-UMB only: ) Connection of Impulse Output for Rain Gauge
Simulation
The digital impulse output is available between pin 7 (gray wire) Uout and pin 1 (white) GND.
In idle state the voltage level at Uout is approximately equal to the supply voltage. Each time
the configured amount of precipitation is reached, Uout is pulsed for about 50ms to GND
level.
Activation of the rain gauge simulation mode and selection of the resolution have to be set
by ConfigTool.NET.
For details please refer to Chapter 10.2.

9 Commissioning
After the equipment has been installed and connected correctly, the sensor begins
autonomously to take measurements. A Windows® PC with serial interface, UMB-Config-
Tool software and interface cable (SUB-D 9 pole; jack - socket; 1:1) are required for
configuration and test purposes.
Attention must be paid to the following points:
Check for correct equipment operation on site by carrying out a measurement request with
the aid of the UMB-Config-Tool (see page 39).
Configure the local altitude in order to ensure the correct calculation of relative air
pressure (see page 34).
The device must be aligned to the North in order to ensure correct wind measurement
(see page 24), or the automatic compass correction must be activated (see page 34).
In order to get correct compass headings the local declination must be configured (see
page 18and 34).
If several Smart Weather Sensors are operated on a UMB network, a unique device ID
must be assigned to each device (see page 33).
There is no protective cover to remove on the sensor itself.

10 Configuration and Test
Lufft provides Windows® PC software (UMB-Config-Tool) for configuration purposes. The
sensor can also be tested and the firmware updated with the aid of this software.
Note: UMB-Config-Tool is not suitable for configuration settings of the WS100-UMB.
ConfigTool.NET shall be used for configuration settings of the WS100-UMB. Please
refer to the ConfigTool.NET manual.
Attempts to modify the settings of the WS100-UMB by UMB-Config-Tool may render the
device inoperative.
The function test of the WS100-UMB (channel selection and measurement polling) can
optionally be done using UMB-Config-Tool.
With regard to contents the following description applies also to WS100-UMB, as far as the
specific instrumentation of this type is concerned.

Modbus-RTU, Modbus-ASCII, Terminal-Mode, XDR).
Timeout: In the event of a temporary changeover of the communications protocol, the
system switches back to the configured protocol after this time (in minutes)
Important note: If the baud rate is changed, after saving the configuration on the sensor,
the sensor communicates at the new baud rate. When operating the sensor in a UMB
network with ISOCON-UMB, this baud rate must not be changed; otherwise the sensor is
no longer addressable and can no longer be configured.
10.2.4 Temperature, Humidity and Fan Settings
Offset: Absolute offset on the measurement in the unit of the accompanying
channel (for on-site calibration).
Interval: Time in minutes for the minimum, maximum and average value calculation
interval.
Fan: to reduce electrical power consumption, the fan can be switched off.
Note: if the fan is switched off, all heaters will also be switched off!
With the fan switched off deviations in temperature and humidity
measurement can occur by solar radiation!
Note: In order to calculate dew point, absolute humidity and mixing ratio, the temperature
and humidity measurement always requires the same interval. For this reason different
intervals cannot be set.

functioning and accuracy of the sensor.
10.2.8 Precipitation Sensor Settings (Rain Gauge)
The rain gauge module can be operated with resolutions 0.2mm or 0.5mm. The setting of the
resolution is to be done in two steps:
Mechanical setting
Configuration setting
The mechanical setting works by modifying the effective area of the funnel. The sensor is
delivered with a reduction ring, which can be mounted on the funnel to reduce the area.
Funnel with reduction ring resolution 0.5mm
Funnel without reduction ring resolution 0.2mm
Then the resolution is set in the sensor configuration using the UMB Config Tool.
Caution: If mechanical setting and configuration setting do not conform, the sensor will
deliver wrong precipitation values!

10.4 Operating Modes of the Smart Weather Sensor
The power consumption of the Smart Weather Sensor can be adjusted to the properties of
the individual installation by setting the operation mode.
The operation of the power save modes however has certain constraints. These have to be
considered when designing the installation.
In normal operation, where all specified properties of the Smart Weather Sensor are fully
available, the power consumption is mostly determined by heating and fan operation.
10.4.1 Power Saving Mode 1
Following measures are active in power saving mode 1:
The ventilation of the temperature / humidity unit is switched off
All heaters are switched off
The radar rain sensor (WS800-UMB, WS700-UMB, WS600-UMB, WS400-UMB, WS100-
UMB) is not working continuously. The sensor is activated once per minute for one second
(WS100-UMB: 5sec), if precipitation is detected, it remains turned on until the end of the
event, otherwise it is deactivated after this one second again.
Compass measurement is only performed once after power up. The fan, which is
otherwise deactivated, will be switched on shortly for the time of this measurement.
The WS700-UMB / WS800-UMB increases the measuring cycle time for global radiation
from 10 seconds to 1 minute.
Note: This setting has the following restrictions:
With the fan switched off deviations in temperature and humidity measurement can occur
by solar radiation.
Only limited winter operation is possible in this operating mode because any icing might
prevent the correct operation of the rain sensor or wind meter.
The rain detection may be delayed up to 2 minutes. Short events are possibly not
detected. Thus, deviations in the accuracy of the precipitation quantity are possible.
Compared with normal operation the power consumption of a WS600-UMB can be reduced
to 10% even neglecting the heating. (during precipitation events the consumption is slightly
higher, due to the rain sensor then permanently switched on, about 20% compared to normal
operation).
Operating Manual Smart Weather Sensor
G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany 41
10.4.2 Power Saving Mode 2
Power saving mode 2 permits another relevant reduction of the power consumption, but
adds on the other hand more severe restrictions.
In this operation mode the device will be almost completely switched off and will wake up
only by the data request for one measurement cycle. During measurement and data
transmission the device will be switched on for about 10 – 15 sec. The total consumption will
be mostly determined by the data request interval.
Note: This operating mode has the following restrictions:
All restrictions of power saving mode 1
Power saving mode 2 is not available for devices with radar rain sensor (WS800-UMB,
WS700-UMB, WS600-UMB, WS400-UMB, WS100-UMB). We recommend devices with
tipping bucket rain gauge for low power applications.
The calculation of average, minimum and maximum as well as precipitation intensity are
not available. Only instantaneous values will be transmitted.
Compass measurement is only performed once after power up. The fan, which is
otherwise deactivated, will be switched on shortly for the time of this measurement.
Communication protocol Modbus is not available
When using the UMB protocol a certain request sequence and timing is required (s. Chap.
19.3.7). The interval length must be at least 15sec to make sure that the measurement
and transmission cycle can be completed. Shorter interval could cause the device to stay
in transmission state without starting a new measurement.
The joint operation with other sensors in an UMB network is possible, but it has to be
considered that each telegram (even when addressed to another device) will cause the
Smart Weather Sensor to wake up for at least several seconds, thus increasing the total
power consumption. The minimum interval length must be hold up under consideration of
the telegrams with other addresses. Mixed operation of devices in power saving mode 2
with devices in normal operation and fast request rates within the same UMB network is
not possible.

Note: Model WS30x-UMB and WS401-UMB are not heated.
The rain sensor and wind meter settings must be adjusted in the respective configuration
mask. The examples show the wind meter setting.
10.5.1 Automatic
In this operating mode, the sensor is maintained constantly at the control temperature,
generally in order to prevent the effects of snow and ice.
Setpoint Temp.: The heating controls at this temperature (in °C)
The settings for the other values are not relevant.
10.5.2 Off
In the ‘Off’ operating mode heating is completely disabled. Winter operation is not possible in
this operating mode because any icing might prevent the correct operation of the rain sensor
or wind meter.
The value settings are not relevant.
10.5.3 Mode 1
In ‘Mode 1’ operating mode heating is only enabled when the outside temperature falls below
the HeatingMode1 temperature (in °C). In this mode power consumption can be reduced in
frost-free situations with no great restriction on winter operation.
Setpoint Temp.: The heating controls at this temperature (in °C)
Heating mode1 Temp.: Threshold temperature (in °C) with effect from
which air temperature heating is enabled
The ‘Eco Mode1 follow-up time’ setting is not relevant.
Operating Manual Smart Weather Sensor

10.5.4 Eco-Mode 1
Eco Mode1 is an advanced energy saving mode.
Heating is only switched on when the following conditions are met:
The outside temperature is below the threshold temperature and precipitation was
detected. Heating then runs at the control temperature for 30 minutes (after the last
precipitation event).
When the outside temperature lies constantly below the threshold temperature and there
was no heating for more than 20h, heating is switched on for 30 minutes as a
precautionary measure in order to thaw any icing.
However, the precautionary 20h-heating only runs if the outside temperature was measured
at below the threshold temperature for the entire period and conditions were constantly
bright for at least 3 hours.
Setpoint Temp.: The heating controls at this temperature (in °C)
Heating mode1 Temp.: Threshold temperature (in °C) with effect from
which heating is enabled
Eco mode1 follow-up time: Follow-up time (in minutes)
Examples:
Outside temperature constantly below 5°C; no precipitation for more than 24h
Outside temperature constantly below 5°C; with precipitation

11 Firmware Update
To keep the sensor in accordance with the latest state-of-the-art, it is possible to carry out a
firmware update on site with no need to remove the sensor and return it to the manufacturer.
The firmware update is carried out with the aid of the UMB-Config-Tool.
The firmware update of the WS100-UMB is carried out with ConfigTool.NET.
The description of the firmware update can be found in the instructions for the UMB-Config-
Tool. Please download the latest firmware and UMB-Config-Tool from our website
www.lufft.com and install it on a Windows® PC. You can find the instructions here:
Note: When a firmware update takes place, under certain circumstances the absolute
precipitation quantities are reset (channel 600 – 660).
There is one firmware for the entire product family (except WS100-UMB) which supports all
models (WSx_Release_Vxx.mot).
The firmware for WS100-UMB is named WS100_Release_Vxx.bin.
Important Note: please read the included text file in WSx_Release_Vxx.zip; it contains
important information about the update!
12 Maintenance
In principle the equipment is maintenance-free.
However, it is recommended to carry out a functional test on an annual basis. When doing
so, pay attention to the following points:
Visual inspection of the equipment for soiling
Check the sensors by carrying out a measurement request
Check the operation of the fan (not on WS200-UMB)
In addition, an annual calibration check by the manufacturer is recommended for the
humidity sensor (not on WS200-UMB). It is not possible to remove or replace the humidity
sensor. The complete Smart Weather Sensor must be sent to the manufacturer for testing.
Cleaning of the glass dome at regular intervals is suggested for devices with global radiation
measurement. The length of the interval should be adapted to the local degree of pollution.
Devices with precipitation measurement by rain gauge (WS401-UMB, WS601-UMB): The
rain gauge funnel needs to be cleaned at regular intervals (see below). The length of the
interval should be adapted to the local degree of pollution.
Operating Manual Smart Weather Sensor
G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany 45
Figure 24: WS601-UMB
with removed funnel
12.1 Maintenance of the Rain Gauge
The function of the rain gauge will be significantly influenced by pollution of the funnel or the
tipping bucket mechanism. Regular check and, if necessary, cleaning is required. The
maintenance interval depends very much on local conditions and also on seasons (leaves,
pollen, etc.) and therefore cannot be exactly defined here (it may be in the range of weeks).
Only clean when obviously polluted
Avoid moving the tipping mechanism (otherwise wrong counts will occur)
Use water, soft cloth and / or a soft brush for cleaning
Unlock funnel by turning it to the left and lift it off
Clean funnel, specially the sieve slots
Check the inside of the rain gauge module for pollution, especially for spider webs
and insects, if necessary, clean it
Check tipping bucket for pollution, if necessary wash carefully with clean water.
Caution: each movement of the bucket generates a counting pulse and thus may
cause faulty precipitation amounts
Check water drain, clean if necessary
Put funnel back in place and lock it by turning it to the right

appears too low
Check the operation of the fan on the underside of
the device.
Wind direction values are incorrect
Device is not correctly aligned check that the
device is aligned to the North.
Device transmits error value 24h
(36d)
A channel is being polled that is not available on this
device type; e.g. Channel 200 = humidity is being
polled on a WS200-UMB.
Device transmits error value 28h
(40d)
The device is in the initialization phase following
startup the device delivers measurements after
approx. 10 seconds.
Device transmits error value 50h
(80d)
The device is being operated above the limit of the
specified measuring range.
Device transmits error value 51h
(81d)
The device is being operated below the limit of the
specified measuring range.
Device transmits error value 55h
(85d) during wind measurement
The device is unable to execute a valid
measurement due to the ambient conditions.
This may be due to the following reasons:
- The device is being operated well above the limit of
the specified measuring range
- Very strong horizontal rain or snow
- The wind meter sensors are very dirty clean
sensor
- The wind meter sensors are iced over check
heating mode in the configuration and check
heating function / connection
- There are foreign objects within the measuring
section of the wind meter
- One of the wind meter’s sensors is faulty return
device to manufacturer for repair
The quality of the wind
measurement is not always100%
In normal operation the device should always
transmit 90 – 100%. Values up to 50% do not
represent a general problem.
When the error value 55h (85d) is transmitted this
value is 0%.
If the device permanently transmits values below
50% this may mean that there is a fault.
Device transmits an error value not
listed here
This may be due to a number of reasons contact
the manufacturer’s technical support department.

18 External Sensor
18.1 External Temperature and Precipitation Sensors
18.1.1 Connection of Temperature and Precipitation Sensors
Additional external sensor can cover the requirements of special measurement requirements
or extend the functionality of Smart Weather Sensors.
Currently the accessory list includes external temperature sensors and the precipitation
detection by tipping bucket rain gauge.
One input is available for this extension, so alternatively one temperature sensor or one
precipitation sensor may be used.
The connection uses the standard connector plug of the Smart Weather Sensor, so normally
the external device will be connected at the end of the cable included with the delivery, in the
control cabinet. As this cable is part of the measuring line care shall be taken when
designing the cabling to avoid parasitic coupling etc. The cable should be as short as
possible. In special cases, e.g. when the external sensor is mounted near to the Smart
Weather Sensor while the control cabinet is distant, the installation of an additional
distribution box should be considered.
The external sensor is connected to pins 5 and 6 of the connector plug, i.e. the grey and pink
wires of the standard cable.
All currently available sensors are unipolar, so the connection sequence is not relevant.
The Smart Weather Sensor must be configured for the selected type of external sensor
(temperature or precipitation) to enable the correct evaluation of the measurement data. The
selection of the sensor type is done through the UMB Config Tool.
If the data from the channels of the sensor type currently not selected are requested, the
device will respond with “invalid channel”.

Figure 39: Example
WS501-UMB and
WTB100
18.1.2 External Temperature Sensor
All models of the WS family (except WS100-UMB) can be used with an external temperature
sensor.
For different application various types of NTC sensor are in supply:
WT1 for temperature acquisition of devices and surfaces
WST1 for mounting in the road surface (road surface temperature)
Mounting / installation of the temperature sensors is shown in the sensor manual.
18.1.3 External Rain Gauge
All models of the WS family without integrated precipitation detection can be used with an
external rain gauge. Models WS100-UMB, WS400-UMB, WS600-UMB, WS401-UMB,
WS601-UMB, WS700-UMB, WS800-UMB with R2S sensor resp. integrated tipping bucket
cannot be equipped with an external rain gauge.
The measurement values of the external rain gauge are on the same channels as the data of
the internal precipitation sensors of WS100-UMB, WS400-UMB, WS600-UMB, WS401-UMB,
WS601-UMB, WS700-UMB and WS800-UMB.
The external rain gauge WTB100 uses the same technology as the integrated rain gauge of
models WS401-UMB and WS601-UMB.
The resolution of the rain gauge WTB100 can be modified by the reduction ring delivered
with the sensor from 0.2mm to 0.5mm.
In principle, all rain sensors with bounce-free reed contact (normally open or normally
closed) and with a resolution of 0.1 mm, 0.2 mm, 0.5 mm or 1.0 mm can be used.
Note: To get the correct amount of rain this “mechanical” selection must be also be set in
Smart Weather Sensors configuration.
The setting is done with the UMB Config Tool by the same procedure as with WS401-UMB
and WS601-UMB (s. Chap.10.2.8).
The WS601/401-UMB’s advices for installation (Chap.7.3.4) and maintenance (Chap.12.1)
are as well valid for the external rain gauge.
Example with WS501-UMB and WTB100 without reduction ring:

19.3.2 Addressing with Class and Device ID
Addressing takes place by way of a 16 bit address. This breaks down into a Class ID and a
Device ID.

ID = 0 is provided as broadcast for classes and devices. Thus it is possible to transmit a
broadcast on a specific class. However this only makes sense if there is only one device of
this class on the bus; or in the case of a command, e.g. reset.

19.3.3 Examples for Creating Addresses
If, for example, you want to address WS400-UMB with the device ID 001, this takes place as
follows:
The class ID for the Smart Weather Sensor is 7d = 7h;
the device ID is e.g. 001d = 001h
Putting the class and device IDs together gives the address 7001h (28673d).
19.3.4 Example of a Binary Protocol Request
If, for example, a Smart Weather Sensor with the device ID 001 is to be polled from a PC for
the current temperature, this takes place as follows:
Sensor:
The class ID for the Smart Weather Sensors 7 = 7h;
The device ID is 001 = 001h
Putting the class and device IDs together gives a target address of 7001h.
PC:
The class ID for the PC (master unit) is 15 = Fh;
the PC ID is e.g. 001d = 01h.
Putting the class and device IDs together gives a sender address of F001h.
The length <len> for the online data request command is 4d = 04h;
The command for the online data request is 23h;
The version number of the command is 1.0 = 10h.
The channel number is in <payload>; as can be seen from the channel list (page 69), the
current temperature in °C in the channel is 100d = 0064h.
The calculated CRC is D961h.

Interpretation of the response:
<status> = 00h device o.k. (≠ 00h signifies error code; see page 74)
<typ> = Data type of the following value; 16h = float (4 bytes, IEEE format)
<value> = 41B40000h as a float value corresponds to 22.5
The temperature is therefore 22.5°C.
The correct data transmission can be checked with the aid of the check sum (22C6h).
Note: Little Endian (Intel, low byte first) applies when transmitting word and float variables of
addresses or the CRC, for example. This means first the LowByte and then the HighByte.

53h (83d)
54h (84d)
Error in measurement data or no valid data available
55h ( 85d)
Device / sensor is unable to execute valid measurement due to ambient conditions
19.3.6 CRC Calculation
CRC is calculated according to the following rules:
Norm: CRC-CCITT
Polynomial: 1021h = x16 + x12 + x5 + 1 (LSB first mode)
Start value: FFFFh
You can find further information in the description of a CRC calculation in UMB Protocol.
19.3.7 Data Request in Power Saving Mode 2
When in power saving mode2 the processor of the Smart Weather Sensor will be usually in
sleep state. For the acquisition of measurement data a certain command sequence and a
certain timing is required:
„Wake Up“ bei sending a <Break>, any character or any telegram (a telegram will
not be properly detected and get no response, because the UART is just starting)
1000msec pause for the processor start up
Activation of the measurement cycle by (any) valid telegram addressed to this
device
2000msec pause for the execution of the measurement sequence
Request of the measurement results
Example of a Request Sequence:

19.4 Communication in ASCII Protocol
Note: UMB-ASCII protocol is not recommended for new projects. New features and
sensors will not be implemented for this protocol for devices newer than device
version 223 (WS100-UMB device version 04).
Text-based communication with devices is possible using ASCII protocol.
To do this, in the device configuration, interface settings, the protocol mode must be set to
ASCII (see page 33).
ASCII protocol is network-compatible and serves exclusively for online data requests. The
device will not respond to incomprehensible ASCII commands.
Note: The use of binary protocol is recommended for lengthy transmission routes (e.g.
network, GPRS/UMTS), as ASCII protocol is unable to detect transmission errors (not CRC-
secured).
Note: TLS channels are not available in ASCII protocol.
19.4.1 Structure
An ASCII command is introduced by the ‘&’ character and completed by the CR (0Dh) sign.
There is a space character (20h) between the individual blocks in each case; this is
represented by an underscore character ‘_’. Characters that represent an ASCII value are in
ordinary inverted commas.

19.4.3 Online Data Request (M)
Description: By way of this command, a measurement value is requested from a specific
channel.
Request: ‘&’_<ID>5_‘M’_<channel>5 CR
Response: ‘$’_<ID>5_‘M’_<channel>5_<value>5 CR
<ID>5 Device address (5 decimal places with leading zeros)
<channel>5 Indicates the channel number (5 decimal places with leading zeros)
<value>5 Measurement value (5 decimal places with leading zeros); a measurement
value standardized to 0 – 65520d. Various error codes are defined from
65521d – 65535d.
Example:
Request: &_28673_M_00100
By way of this request, channel 100 of the device with address 28673 is interrogated (Smart
Weather Sensor with device ID 001).
Response: $_28673_M_00100_34785
This channel outputs a temperature from –50 to +60°C, which is calculated as follows:
0d corresponds to -50°C
65520d corresponds to +60°C
36789d corresponds to [+60°C – (-50°C)] / 65520 * 34785 +(-50°C) = 8.4°C
Note: TLS channels are not available in ASCII protocol.

19.5 Communication in Terminal Mode
It is possible to communicate with a device in a very simple text-based manner using the
terminal mode.
To do this, in the device configuration, interface settings, the protocol mode must be set to
terminal (see page 33).
Note: In the case of communication in the terminal mode, only one single unit may be
connected to the interface, as this protocol is NOT network-compatible. It is used for very
simple measurement value requests.
Note: The use of binary protocol is recommended for lengthy transmission routes (e.g.
network, GPRS/UMTS), as it is not possible to detect transmission errors in terminal mode
(not CRC-secured).
Note: In the terminal mode, measurement values are not available in all units. Furthermore,
status and error messages are not transmitted.
19.5.1 Structure
A terminal consists of an ASCII character and a numeric character. The command is
completed with the <CR> sign. There is no echo on entry.
The individual values in the response are separated by a semi-colon (;). The response is
completed with <CR><LF>.
An invalid terminal command is acknowledged with ‘FAILED’. Control commands are
acknowledged with ‘OK’.
The command to which the response relates is given at the beginning of each response.
Note: No response times are specified in the terminal mode.

19.6 Communication in SDI-12 Mode
The communication in the SDI-12 mode of the Smart Weather Sensor is conforming to the
standard defined in ‚SDI-12 A Serial-Digital Interface Standard for Microprocessor-Based
Sensors Version 1.3 January 12, 2009‘ . The device may be operated in bus mode together
with other SDI-12 sensors, connected to one SDI master (logger).
19.6.1 Preconditions for SDI-12 Operation
As the interface settings defined in the SDI-12 standard are significantly different from the
UMB default settings the related parameters have to be set properly by the UMB Config Tool
(latest version!).
The protocol mode of the device has to be set to “SDI-12”. This will automatically set the
baud rate to 1200.
Measurement data can be transmitted alternatively in metric or US units. The selection is
done by the UMB Config Tool.
Metric units US units
Note: Please observe drawings on next page and notes on page 27 when connecting a
SDI12 data logger!

When operating the device in SDI-12 mode it is basically no more possible to access the
device with the UMB Config Tool, due to the different interface parameter settings. To enable
configuration access nevertheless the interface is operated in standard UMB mode (19200
8N1) for the first 5 seconds(*) after reset / power on. During this time the UMB device ID, if
unequal 1, is set to 200, so access will be possible even if the device ID is unknown. If a
valid UMB telegram is received within this 5 sec, the device will stay in UMB mode for the
configured time out (several minutes) so that the configuration can be modified.
Connect the PC to the Smart Weather Sensor through an RS-485 converter
Start the UMB Config Tool and create a WSxxx-UMB with the address (1 or 200) of
the actual device and activate at least one sensor. Start the measurement (will
report connection error at first)
Reset the device (Power off / on)
When measurement values are received the measurement can be terminated, the
interface is now open for configuration.
(*) Remark: The 5 seconds UMB communication are available from program start. Under
consideration of the operating system start, where no communication is possible, the device
will be ready for SDI12 requests after 7.0 – 7.5 seconds.
This timing only applies in case of cold start after power on or reset. This phase will not
occur after “wake up” in Power Saving Mode 2. In this case the device will respond within the
time defined by the SDI12 standard.

The composition of the minimal and the full basic data set depends on the variant (WS100-
UMB ... WS800-UMB) of the device in question (see below). The same applies to the
availability of the additional measurement commands (aM1!, aC1! etc.)
Due the applied measurement processes the devices of the WS family will, different from
other sensors described in the SDI-12 document, in normal operation mode always
measure continuously. This causes some special properties while in this mode:
The device does not need a “Wakeup” and does not have a sleep mode. So the
reactions to “Break” signals and any related timings are inapplicable. “Break” will be
ignored by WS devices.
Data requested with M- or C- commands are always available immediately. The
device will always respond with a000n resp. a000nn. This means the device will not
send any service request and will ignore measurement abort signals. The logger
should request the data immediately.
M- and C- command only differ in the number of values made available in the buffers
(in both cases the maximum permitted by the standards of 9 resp. 20).
We recommend to use the commands for continuous measurement (R-commands)
to request the data.
When in power saving mode 2 the device will wake up by a „Break“ signal. Other
functions of the „Break“ signal are not implemented.
When in power saving mode 2 the device responds to M or C commands with
a002n resp. a002nn and holds the data available within 2 seconds. It will not send a
service request, signals to abort the measurement are ignored.
For the reduced data set in power saving mode 2 a unified data buffer structure for
all device models has been defined. Depending on the individual model unused
channels will be set to the “invalid” marker 999.9.

19.6.3 Address Configuration
UMB Device-ID and SDI-12 Address are connected, but the different address ranges and the
fact, that UMB ID’s are integer numbers, while SDI-12 addresses are ASCII characters, have
to be considered.
The SDI-12 address is built from the UMB device ID as follows:
UMB Device ID 1 (default) corresponds to SDI-12 Address ‘0’ (SDI-12 default).
Changing the SDI12 address by SDI12 setting command also modifies the UMB device ID
accordingly.
Valid Address Ranges:

19.6.4 Data Messages
In the interest of simplified evaluation the assignment of measurement values to data buffers
‘0’ ... ‘9’ has been defined unified for all measurement commands. For this reason the
responses to C-requests have been restricted to 35 characters, not using the 75 characters
permitted for these requests
Currently buffers ‘0’ to ‘4’ are in use.
As with M-requests max. 9 values may be transmitted; the base data set of 9 values has
been assigned to buffers ‘0’ and ‘1’. Buffers ‘2’ to ‘4’ contain further measurement values.
This definition guaranties the compatibility to loggers designed according to older versions of
the SDI-12 standard.
The buffer assignment depends on the device variant (WS100-UMB ... WS800-UMB).
The complete set of measurement values, as defined for the UMB protocol has been made
available also in the SDI-12 environment. They can be accessed using the additional M and
C commands (aM1! ... aM8!, aMC1! ... aMC8!, aC1! ... aC8!, aCC1! ... aCC8!) (see below).
If the measurement value is not available for some reason, e.g. sensor failure, this is
indicated by a value of +999.0. or -999.9 The logger can then evaluate the reason of failure
by a aV! Verification request. The following tables show the measurement values in the
sequence they are arranged in the telegram (see example).
Depending on the configuration of the device the values will be transmitted in metric or US
units.
Note: The configured system of units is not indicated in the data messages. The logger may
request this setting with the I-command and adjust the evaluation of the data messages
accordingly

19.6.5 Additional Measurement Commands
With the additional measurement commands
aM1! … aM8!
aMC1! … aMC8! (M-Command, data transmission with CRC)
aC1! … aC8!
aCC1! … aCC8! (C- Command, data transmission with CRC)
The complete data sets of the Smart Weather Sensor, as defined for the UMB protocol are
available in a SDI-12 environment as well.
The measurement values are ordered according to sensor types.
Equally to the base data sets max. 9 values can be requested with an additional M
command, while an additional C request allows for up to 20 values.
The buffer assignment as documented in the following paragraphs has consequently been
structured in a way that with each M command the buffers D0 and D1 are used. If the
respective sensor type has more values available the buffers D2 up to D4 will be occupied if
required.
M1 / C1 Temperature M: 9 Values C: 9 Values
M2 / C2 Humidity M: 9 Values C: 13 Values
M3 / C3 Air Pressure M: 9 Values C: 9 Values
M4 / C4 Wind M: 9 Values C: 14 Values
M5 / C5 Compass M: 1 Values C: 1 Values

WS100-UMB: Drop Diameter Distrib. M: --- C: 17 Values
Others: Global Radiation M: 4 Values C: 4 Values
M8 / C8 Ext. Temperature M: 1 Value C: 1 Value
If the sensor type requested with the measurement command is not available with the actual
variant of the Smart Weather Sensor (WS100-UMB ... WS800-UMB) the device will respond
with
a0000<CR><LF> resp.
a00000<CR><LF>

The device responds to the identification request with following message (example for SDI-

0I!
013Lufft.deWSx00ynnn
x: device type (4, 5, 6, 2, 3 )
y: Metric / US units ( m = metric, u = US )
nnn: Software version
i.e. for a WS600-UMB, configured for US units:
0I!
013Lufft.deWS600u022
19.6.7 Message Verification
The command verification aV! is used to evaluate status information of the device. The
device responds with
a0005<CR<LF> WS700/800-UMB: a0006<CR<LF>
to the request, i.e. 5 (6) values are available in the buffers.
The first 3 (4) “measurement values”, transmitted in buffer ‘0’ contain the status information
of the measurement channels.
The status data of the channels are assembled to form “fake measurement values”, where
each digit represents one status. See below for the coding of states. Generally each sensor
has two status values, one for the direct value and another for the measurement value buffer
used for the evaluation of the average, min, and max values.
The last two values, transmitted in buffer ‘1’, show the heating temperatures of wind and
precipitation sensor.

19.7 Communication in Modbus Mode
For a simpler integration of WS family Smart Weather Sensors into a PLC environment the
Modbus communication protocol has been made available.
Measurement values are mapped to Modbus Input Registers. The range of values available
is basically the same as for the UMB protocol, including different unit systems.
In the interest of simple and safe integration the use of register pairs for floating point values
or 32 bit integers, which is not part of the Modbus standard, has not been applied. All
measurement values are mapped to 16bit integers using suitable scaling factors.
19.7.1 Modbus Communication Parameters
The Smart Weather Sensor can be configured for MODBUS-RTU or for MODBUS-ASCII.
The base configuration has to be done using the UMB Config Tool.
When selecting MODBUS RTU or MODBUS-ASCII with the UMB Config Tool,
communication parameters 19200 Bd, even parity, will be preselected.
Modbus operating modes: MODBUS-RTU, MODBUS-ASCII
Baud rate: 19200 (9600, 4800 or lower)
Interface Setting 8E1, 8N1, 8N2
NOTE: The Modbus communication has been tested for a poll rate of 1 sec. The proper
function of the Smart Weather Sensor with higher Modbus poll rates has not been tested.
We suggest to set the poll rate to 10 sec or slower, as, with the exception of the channels
„wind speed / wind directions fast“, which are provided for special purposes, the update rate
of the data is >= 10sec. Anyway for most of the weather data significant changes have tob e
expected more in the range of minutes.
19.7.2 Addressing
The Modbus address is deducted from the the UMB device ID (see Chap. 19.3.2).
A device with UMB device ID 1 also has the UMB address 1, etc..
The valid address range of Modbus from 1 to 247 is smaller than that of the UMB device IDs.
If a UMB device ID > 247 has been selected, the Modbus address will be set to 247.
19.7.3 Modbus Functions

applicable for the Smart Weather Sensor, i.e. all functions operating on register level.

19.7.3.2 Function 0x06 Write Holding Register, 0x10 Write Multiple Registers
By writing into the holding registers selected parameters of the Smart Weather Sensor can
be adjusted through Modbus.
Register assignment see19.7.3.1
Local altitude, compass deviation and averaging intervals are set by writing the new values
into the related registers. Depending on the selected register the value has to be scaled by
the factor given in the table:
Example: for compass deviation the table shows a scaling factor of 10.0. If the deviation is
4.8° a value of 48 shall be written into register 2 (reg.addr. 1).
The transmitted values will be checked for plausibility. Illegal values will not be accepted and
cause a Modbus exception.
When writing the value 0x3247 (12871d) to register no. 8 (reg. addr. 7) the stored absolute
rain amount will be set to 0. Subsequently a device reset will be initiated.
When writing the value 0x3247 (12871d) to register no. 9 (reg. addr. 8) a device reset will be
initiated.
Setting of the heating mode:
The wind sensor heating mode is coded into the high byte of the 16bit register no. 7, the
precipitation sensor heating mode into the low byte of this register
Example :
Heating mode wind: Mode 1 (Code 1)
Heating mode precipitation: Off (Code 2)
Write to register 7 (reg. addr. 6): 0x0102 (=258d)
Operating Manual Smart Weather Sensor
126 G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany
Setting for minimum power consumption, both heatings off (Code 2):
Write to register 7 (reg. addr. 6): 0x0202 (=514d)
The factory setting for a WS600-UMB is automatic mode for both heatings, i.e. 0x0000.
When attempting to set a heating mode not supported by the individual device variant, e.g.
activating the precipitation heating of a device without precipitation sensor, the device will
automatically adjust the value written to the register, so that the value read back from the
register might be different from the written value.

19.7.3.3 Function 0x04 Read Input Registers
The input registers are containing the measurement values of the Smart Weather Sensor
and the related status information.
The measurement values are mapped to the 16bit registers using scaling factors (0 … max.
65530 for unsigned values, -32762 … 32762 for signed values).
Values 65535 (0xffff) resp. 32767 are used for the indication of erroneous or not available
measurement values. A more detailed specification of the error can be evaluated from the
status registers.
The assignment of values to the available register addresses (0 … 124) has been arranged
in a way so that the user can read the most frequently used data with few (ideally only one)
register block requests
Following blocks have been defined:
Status information
Frequently used values which are independent of the unit system (met./ imp.) in use
Frequently used values in metric units
Frequently used values in imperial units
Other measurement values
When using the metric unit system the first three blocks can the supply all data usually
required with one request.
There is no difference in the register assignment between the sub types of the WS family. If,
dependent on the type, some value is not available, this will be indicated by setting the
register to the error value.
For detailed information about measurement ranges, units etc. please refer to the related

Sensor Status:
Each register hoIds 4 sensor status coded with 4 bits per status, so that together they build
one 16bit number. The sequence defined in the table above is to understand as from most
significant half byte to least significant half byte. Most of the sensors have two status values,
one for the sensor itself and the current measurement value, another one for the buffer, from
which average, min. And max values are evaluated.

Configuration XDR
19.8 Communication: XDR Protocol
Note: XDR protocol is not available for WS100-UMB.
The XDR protocol allows to transmit a selected data set of the Smart Weather Sensor in a
NMEA compatible format. The data telegram can be transmitted on request, or the Smart
Weather Sensor can be set into auto transmit mode, where the data telegram will be
triggered automatically at an selectable interval.
A set of ASCII configuration messages allows to apply some configuration settings without
leaving the XDR protocol.
For configuration settings exceeding this command set use the UMB Config Tool. To change
into the UMB protocol a UMB message must be addressed to the device within 5 seconds
after power up or reset.

Termination Characters
The command data field always starts with the 2-character command identifier, optionally
followed by a parameter, starting with '='.
Currently implemented commands are
P9 single measurement XDR format
PP start continuous measurement XDR format
PB single measurement PWSD format
PC start continuous measurement PWSD format
GW option: add MWD sentence (wind data) to XDR format
MI continuous measurement interval

BR baud rate
ID unit ID
NH message prefix
If the device receives an invalid command (missing start or termination character, invalid ID,
invalid structure etc.), it will not respond.
If a setting command contains an invalid parameter value, the device will not respond.
Setting commands must usually be preceded by the “Write Enable” command EW. This
command does not generate a response, and may be, different from other commands,
transmitted without message terminators (<CR><LF>). I.e. the write enable and the set
command may be concatenated without terminators between the commands.
Example:
0100EW*0100J3=1<CR><LF>
and
0100EW<CR><LF>*0100J3=1<CR><LF>
are both valid command sequences for setting the pressure mode.
Setting commands not requiring a preceding write enable are marked in the command
description.

19.8.4 Message Format for Measurement Data MWD
The P9 / PP measurement data transmission can be optionally extended by a MWD
sentence containing wind data. The MWD sentence follows the definition for NMEA WI
(weather instrument) messages.
This option can be activated or deactivated by the GW command.
The JW command selects between spot value and average value output of wind data.
The message is field oriented, with variable length. The fields are separated by ','.

19.8.5 Message Format for Measurement 0R0
The 0R0 sentence format is a proprietary format similar to NMEA 0183 rules. The 0R0
sentence contains essential measurement values of the compact weather station and is
designed for compatibility with existing installations.
The sentence is requested by the PB command for single measurement and PC for cyclic
transmission.
If certain measurement values are not available for the subtype of the individual weather
station the related value will be replaced by 999999. The same applies for measurement
values with status not “OK”.
The message is field oriented, with variable length. The fields are separated by ','.
