Figure 2: Assembly with Sensor-Interface (9.1756.x0.100)
The datalogger DLx-MET is a complete measurement system serving for the acquisition and
storing of at minimum 10 meteorological parameters (e.g. temperature or radiation). Additionally in
the version 9.1756.x0.100 a so-called Sensor-Interface (SIF, see Figure 2) printed circuit board
with several measuring channels is connected to the serial interface COM2. Optional measuring of
other parameters or special sensors with serial output can be done by connecting the so-called
Sensor-Interface or a serial sensor to the serial interface COM2 or COM3 (RS485 2W, 2-Wire, halfduplex). The serial interfaces COM1 (used for commands and data output) and COM2 are
adjustable from operation mode RS232 to RS485-4W (4-Wire, full-duplex). See below Figure 3 for
a overview of all interfaces.

The instrument is battery-operated (12V), thus allowing it to be set up according to model and
sensor equipment at site without any mains supply for some hours or even days (applies not for
sensors measured by the Sensor-Interface). The exchangeable storage battery is situated in the
data logger case. With an optional 12V solar panel it is possible to load the battery.
Additionally a mains power supply (230VAC) can be used, which also supplies (24VAC) the heating
of sensors and the Sensor-Interface (apply only for 9.1756.x0.100). In this case the battery serves
for bridging in case of power failure. The following figure shows the supply possibilities.
Figure 4: Block diagram supply
In order to protect the accumulator against discharging the measurement of the sensors is
interrupted in case the voltage is below 10,5 V (thus the current consumption is minimized). Then,
6 - 56 021579/06/09
Page 7
the voltage is measured every 5 minutes; when it is higher than 11,0 V the normal measuring
routine is continued.
An integrated lithium battery buffers the contents of the data memory and the clock operation when
no other power supply is available. This means that the saved values and the time are not lost even
when there is no additional power supply.
The housing can be locked, is impermeable to jet-water (IP65), and is a very stable construction.
For shielding against electromagnetic fields the housing is made of stainless steel. In addition,
operation is guaranteed for temperatures ranging from – 30 °C to 60 °C.
The instrument can be easily operated either by means of three keys, via serial interface COM1 or
via USB. The three keys are referred to in the following as"<∆>", "<∇>"ON, and "<ENTER>" (see
Figure 5). A three-line, alphanumeric liquid crystal display (LCD) serves as indicating instrument.

The scanning of the measuring values is selectable in the range from 1 second to 60 minutes. For
each of the 10 internal sensors the scanning, and further processing can be switched on or off
separately. The optional sensors connected to the Sensor-Interface are processed if the datalogger
receives a telegram over the serial interface COM2 (apply only for 9.1756.x0.100).
The measuring values are stored in a memory (CMOS-RAM) with a storing rate of 1 to 60 minutes
for mean values and 1 minute to 6 hours for extreme values. The memories are organized as socalled ring memory with a capacity of 1.4MB (mean) and 0.5MB (extreme) . If the capacity of the
ring memory is exhausted, the next step is to overwrite the oldest record. The reading-out of the
data can be carried out via the serial interface COM1, USB or via a Secure Digital Memory Card
(SD Card, see chap.5.2 for working types).
There is a so-called switch output available for the supply of an optional GSM-modem; by means of
this contact output the modem can be supplied at up to 6 selectable times a day.
It is possible to synchronize the internal time automatically by means of a separately connectable
DCF77-receiver module (reception range up to 2000km around Frankfurt(Main)/Germany).
For checking the sensors or the measuring inputs the datalogger can be turned into the
maintenance-mode. While this mode is active the measuring values of all the sensors cannot get
into the memory. I.e. values detected during the maintenance-mode are displayed, however, are
not taken into consideration for the calculation of mean- or extreme values.

2.1 MOUNTING
The datalogger is designed for wall-mounting or installation on a mast.
For proper protection against lightning strikes we strongly recommend to connect a preferably short
cable (≤1m) with a cross section greater than 6mm² between the case (see Figure 1, Grounding
Earth) and the mast (if used) with an earth terminal (e.g. grounding bound or main equipotential
bonding conductor). This connection is also necessary when mains (230VAC) is connected to the
datalogger.
It exists two case variants:
• 9.1756.10.x00x (case version A)
• 9.1756.00.x00x (case version B)
For the mast-installation of case version A seven different pipe clips with a diameter from 46 to
137mm are available. For mast-installation with case version B see chap. 2.1.2

2.1.3 Cable gland
In order to carry out an EMC-compatible installation the cable screen (excepted the supply cable,
which is normally not shielded) is to be connected to the contact spring of the screwed cable gland
(see Figure 10) For wiring plan ref. to chap. 7.
1. With the Standard Contacting (see Figure 10-1)
- Strip back the outer sheath and screen (shielding)
- Make a round cut in the outer sheath approx. 15 mm along but do not remove the sheath
- Guide the cable through the cable gland
- Pull off the outer sheath
- Pull back the cable until the connection is made between the cable screen and contact spring
- Turn shut… and it is ready for use!
2. With thin Wires without an Inner Sheath (see
- Strip back the outer sheath
- Pull back the screen braid approx. 15-20mm over the outer sheath
- Insert the cables into the cable gland until the contact is made between the cable screen and
contact spring
- Turn shut ….and it is ready for use!
3. When Routing the Cable Screen to another Connection (see
- Expose the screen braid approx. 10 mm

2.1.4 Accumulator
The accumulator or battery is to be connected always. It is absolutely necessary to pay attention to
the specified polarity (red -> + ,black -> -)!
Remark:
When changing the accumulator, or with active power- or solar-supply please take care
that the red cable is not in contact with the housing parts (danger of short-cut)
During the installation please take care that all connections are voltage-free, and
that people and/or instruments are not endangered!
When replacing the accumulator with active power supply please take care that the red cable has
no contact with any part of the housing (danger of short-circuit).
A replacing or loading is necessary at the latest when the indicated accumulator voltage decreases
below 9.0V. However, a discharge of the accumulator below 11,0 V should be avoided, as no
considerable capacity is available any more. With operation below 10,5 V the life time of the
accumulator is reduced considerably! The new accumulator should be newly charged before
mounting, because, possibly, it might not have its maximum capacity due to self-discharge (approx.
3 % per month). The stored data are being secured during the replacement. Before disconnecting
the accumulator, the data should be saved. Without accumulator no measurements are being
carried out.
2.1.5 Mains supply
Safety Notes if using mains supply:
Attention! High Voltage. Mortal Danger!
The instrument must be mounted and wired only by qualified personnel, who
knows and observes the generalities of techniques, and applicable regulations
and norms.
Please keep in mind the local safety instructions.
Before carrying out any installation or service isolate unit from the mains supply!
in chapter 2.1.
When a Sensor-Interface(SIF, see Figure 2) board is installed (9.1756.x0.100), it is necessary to
swing open it to connect the 230V-power supply to the transformer or to check the fuses (see
Figure 1). When the both screws at the head of the SIF-board are removed you can turn the board.
When the 230V-power supply cable is installed, and connected, a red LED is active at the
datalogger between clamps 1 and 2 for the function control of the charging connection. In case this
LED does not light, the fuses of the 230VAC-input and the 16VAC-output of the transformer should
be checked.
13 - 56 021579/06/09
Page 14
Additionally a red LED lights up between clamp 67 and 68 for control the 24VAC supply (normally
used for heating of sensors). In case of malfunction check the fuses 230VAC and 24VAC.
Remark for 9.1756.x0.001:
The 26Vac output has no fuse, but a 135°C thermal trip switch which breaks the
primary supply.
2.1.6 Solar panel
Electric Connection:
The connection of the optional solar panel is to be carried out according the wiring plan
(see chap. 7). We recommend to earth the panel for protection against lightning strikes.
The integrated 12V solar regulator generates a temperature-controlled voltage for a
optimum load of the battery. The maximum power of the panel should not exceed 20W,
otherwise the regulator could be damaged. Due to the temperature-controlling the battery
should be always in the case of the datalogger.
Alignment:
• Direction: Always align the panel pointing to the sun at noon (south on the northern
hemisphere and vice versa) for an optimum performance. If necessary, refer to a compass.
• Angle: The optimum tilt angle (angle between the horizontal plane and the solar panel, (see
Figure 11) depends on the latitude of the site. If the datalogger is to be used all the year
round, we recommend a tilt angle for optimum winter performance :
Tilt Angle = Latitude + 15° (apply not for Arctic / Antarctic region, maximum tilt angle 90°)
• Nearby obstacles (trees, sensors etc.) should not block the sun at the panel.
Maintenance:
• Dirt, snow, leaves etc. on the panel reduces the amount of light and decreases the energy
yield. Therefore regularly clean the glass of the panel depending on the vicinity.

2.1.7 DCF-Active Antenna (9.1760.00.000)
For installation of the optional DCF-Active Antenna (9.1760.00.000) it is necessary to notice the
following:
Generally, please take care that the position of the antenna is optimal. It should be aligned
horizontally to, and across the direction of the transmitter (situated near Frankfurt/M., N 50° 01’, E
09° 00’). The antenna should have a minimum distance of 1m from sources of interference such as
power lines, and a 20cm-distance from metal obstacles. For other information on the alignment of
the antenna ref. to chap. 3.2.7 .
2.1.8 Remove Front Plate
For changing or checking of the jumpers for the digital input (ref. to chap. 2.1.9) or for the resistors
of the serial interfaces (ref. to chap. 2.1.10) the front plate (see Figure 5) has to be removed.
First remove the 4 recessed head screws of the front plate. Then move the plate carefully because
otherwise the ribbon cable for the three keys can be damaged.
Before you tighten the screws check the 3 keys of the front plate. When the keys are not working
anymore you had to insert the ribbon cable into the 4-pin connector of the printed circuit board.

2.1.9 Setting Digital Input
The digital input „Event / Length of time” (Sensor 10) can be configured for two possibilities with the
Jumper P2:
* The corresponding switching levels are listed in the technical data (see chap. 6)
** Note that with jumper in position 3 the logic level is reversed by the electronic.
The jumper P2 is situated 2 cm above clamp 13 (see Figure 12). To change or check the position it
is necessary to remove the front plate (see Figure 5, ref. to chap. 2.1.8).

Page 17
2.1.10 Setting Resistors Serial Interfaces
There are three multi-pin connectors for the serial interfaces when used in RS485 mode. To get the
lowest current consumption and no negative impacts when COM1(P5) or COM2(P4) are in the
RS232 mode all respective jumpers must be open. COM1 and COM2 are adjustable by firmware
between RS232 and RS485 (ref. to chap. 3.1 Baudrate setting). COM3 is always in the operation
mode RS485-2w (half-duplex).
To change or check the position of the jumpers it is necessary to remove the front plate (see
Figure 5, ref. to chap. 2.1.8). Figure 13 show the position of the multi-pin connectors:
COM1: 10-pin connecter P5 (above the 9 pin D-plug)

3 OPERATION
When the accumulator is connected, the datalogger starts automatically with the so-called
Bootloader (uploads new Firmware), and re-initialises itself. The Bootloader waits 30 seconds and
start the actual Firmware automatically. After the first activation, time and date should be
controlled.
3.1 DISPLAY OPTIONS
The display is switched on through the button <∇> (press half a second at the most). The display
deactivates itself automatically, if – for 4 minutes – no button was pressed or no signal was sent or

3.2 CHANGING PARAMETERS
All display values which are output with a "*" to top left can be changed.
In order to be able to edit the displayed value, first simply press the <ENTER>-key and then the
<∇>-key. The value to be changed is then indicated by the flashing cursor. Now you can release
both keys. With the <∆> key the value can be raised, or decreased with the. <∇> key. If the set
value is o.k., simply press the <ENTER>-key again in order to leave the edit mode or to proceed to
the next changeable value.
3.2.1 STATION NAME
Station name identifies the measuring station. If several data loggers are in use, then each logger
should be given a different name. All letters and digits can be set as well as the underlining "_" and
the space key.
When the station name is changed in the second line the output language is displayed, and can be
selected through the arrow key.
3.2.2 DATE
If an invalid date is entered (for example.: 31.4.00), it is corrected automatically.
3.2.3 SENSOR CONFIGURATION
For changing the sensor configuration, it is necessary – after pressing the <ENTER>- and <∇> -key
at the same time – to proceed as follows:
The second line is cancelled, and an interrogation mark is output. Afterwards, press the <∇>- and
<∆> -key at the same time for 10 seconds. The „countdown“ is shown on the display. After the
„countdown“ has finished you can change the values as usual.
3.2.4 MEASUREMENT / STORE CYCLE
The measurement cycle indicates the time intervals at which the analogue sensor values are
measured by the data logger and the serial sensors (e.g. sensor-interface SIF) are requested. The
measurement cycle can be changed during operation without the preceding data being lost. All
digital inputs (wind speed, wind direction (every second) and precipitation) are continuously
measured independently from the measured value set.
There are 23 different measurement intervals available:
seconds: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30
minutes: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
The mean storing cycle indicates time interval for storing the measuring values. For this, the
A mean value is calculated from 600 measuring values, and stored. The calculation of the mean
value is carried out as arithmetic mean with „normal“ sensors. Exceptions are the wind direction
(vectorial mean), and precipitation (formation of sums).
Remark:
When adjusting the measuring cycle the cycles of mean value memory and
extreme value possibly have to be corrected to an integral multiple!
The mean storing cycle influences the storing time period of the mean values (see following Table
4 for 9.1756.x0.000 without additional serial sensors (10 channels))
The extreme storing value cycle gives the time point when the extreme values are saved.
The extreme storing value cycle is selectable in 16 steps:
Minutes: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30
Hours: 1, 2, 3, 4, 6
The extreme value cycle influences the extreme value time period (see following Table 4 for 10
channels).
The storage period is the period of time until the old data are overwritten. The data logger has two
ring memories. Both time periods depend on the number of measured channels. Additionally the
time period of the mean value memory depends on the mean storing cycle set. The time period of
the extreme value memory depends similarly on the extreme storing value cycle set.
For other number of channels you can use the following formulas.
[ ]: means rounding down to integer
Calculation of quantity of mean ring memory dataset:
That denote in this case the mean time period is 23.76 days (= 34216 / 1440) when the mean
storing cycle is 1 minute.

3.2.5 ADJUST SERIAL INTERFACES MODE
According to following Table 5 COM2 and COM3 can be switched off (lowest power consumption)
or adjusted for the input of serial sensors and output of telegrams. It is not possible to set both
serial interfaces to the same priority (e.g. COM2 to SIF001 and COM3 to SIF002). With this settings
the number of channels can be changed and in this case the ring memories (mean and extreme)
are new initialised.
To start the setting with the keys the procedure like sensor configuration (ref. to chap. 3.2.3) has to
be done.
Remarks:
Before change this settings save the measuring data of the logger!
In case of changing the number of channels the old mean and extreme data
is no more available!
The baudrate and mode (RS232 or RS485) parameters of a sensor must be same
as the corresponding serial port of the datalogger (COM2 or COM3).
31 - 56 021579/06/09
Page 32
If more than one sensor is selected, the order of the sensor values in the display and memories is
done according the priority in the following table. The sensor with the lowest priority value is output
first. E.g. when Sonic (priority 1) and SIF(priority 3) are set, the values from the Sonic are given out
before the data of the SIF.
The index of the table below shows the values needed for programming via the serial interface
(command “Cs”, ref. to chap.5.5).
To get the lowest power consumption it is necessary to switch COM2 and COM3 off.

The THIES SONIC sensors (“Ultrasonic Anemometer 2D” with software version 3.09 and higher)
are connectable to the datalogger on COM2 (RS485-4Wire, full-duplex) or COM3 (RS485-2Wire,
half-duplex), if the following settings are done:
The data of the SONIC are requested with the command “00TR00002” (VDT-telegram: Wind
speed, wind direction, acoustic-virtual temperature). With the command “SO2”(ref. to chap. 5.5) it
is possible to send a command to the sensor.
32 - 56 021579/06/09
Page 33
3.2.5.2 SENSOR-INTERFACE SIF
In the case of model 9.1756.X0.100 is a so-called sensor-interface SIF build in and is connected to
COM2 (9600Bd 8N1, RS232 mode) of the datalogger. Available are different SIF which separate
between number and type of channels. The data are requested with the command “mm”. The
command “SI2” (ref. to chap. 5.5) can be used to send a command to the SIF.
The timer activates up to 6 daily time slots for an externally connected GSM-modem.
By setting small time slots (for ex. 5 min) the average current consumption of the modem per day
(operating current approx. 200 mA) can be kept down.
During a data transmission via a timer-controlled modem, the remaining power-on-time is fixed on 5
min, thus a re-logging-in in case of a failure is guaranteed within this period.
In the edit mode all timers can be set in turn .
Selectable are the daily starting time, and the minimum power-on-period.
TIMERx: HH:MM
ONLINE: NN min
x = 1,2,3,4,5,6
„HH:MM“ indicates the starting time of the respective timer slot in the format hour:min.
The power-on-period is selectable in minute-increments from 5 to 31. When the power-on-time is
set to 0, the respective timer is deactivated.
Remark:
Only timer 1 is activated even if the discharge-protection for the accumulator is
active (voltage < 10.5V).

DCF77 Test: --
DCF-antenna on DCF-antenna off
This display serves for controlling and setting of the DCF77-antennna.
„ss“: indicates the seconds (0-60, with overflow „??“), after the minute mark has been
identified
„nn“: cycle counter (0-99) of the received second marks.
„D:D.Ds“: time difference of the second marks in seconds (ideal: 1.0s, except for the second
60 (minute mark): 2.0s)
„L:NN B“: length of the second marks in 10ms(NN).
B indicates the binary decoding (L= 6..13[10ms] -> „0“, L= 16...23[10ms] -> „1“,
other lengths are output with “?”)
After this output has been activated, the following values appear for example:
DCF77 Test: ??
2 D:1.0s L:19 1
The minute mark has not yet been identified („??“). The 2. second mark received has a length of
190 (19*10)ms.
The length of the second mark (optimal: L=10 resp. L=20, the length is shorter with weak reception)
is well suited for the optimal alignment of the antenna.
After the minute mark has been recognized (D:2.0s und L: 7...13[10ms]) „ss“ is output and is raised
every second up to a maximum of 60. When the reception is correct, “ss” and “nn” run almost
synchronously. A difference of more than 1 means, that error pulses or not enough pulses have
been received; thus a decoding of the DCF77 time information is impossible.
DCF77 Test: 32
32 D:1.0s L:08 0
Remark:
If the reception is very weak in the daytime, the antenna should be aligned at
night (broader reach). Never try to align the antenna during sunrise or sunset (site
of transmitter and receiver/datalogger) !
Possibly, there are several alignments (neither horizontal!) allowing a reception
(reflections).
The transmitter can be inactive for several hours (thunderstorm close to the
sender).

DCF-antenna on DCF-antenna off
This display serves for switching on and off the DCF-antenna, indicates the last time of
synchronization (third line) and the manual start of synchronization.
When the DCF-antenna is active, it tries to receive a time telegram at night from 01:30 h (max. 10
minutes) because of the better reception. This time telegram is sent during standard time as CET
(“Central European Time”, CET=UTC+1h), and during daylight saving time as CEST (“Central
European Summer Time”, CEST=UTC+2h). This time telegram is converted in UTC, and the
internal clock is synchronized.
In the edit mode the antenna can be activated and deactivated. Additionally in the third line the last
synchronised DCF77-Time is given out:
*DCF: 1
s = 0 CET/standard time
30.04.09 03:33 s
s = 1 CEST/daylight saving time
With active DCF-antenna, and sufficient reception, when you wait approx. 2 minutes or longer, the
DCF time telegram is displayed, and the internal clock is synchronized (provided that no error
occurs).
Example: Reception of a time telegram (year not yet received)

4 MEASURING VALUE ACQUISITION
For reasons of current consumption the display, and other control parts are switched off in case
that for 4 minutes no button has been pressed, or no data communication over COM1 or USB has
been proceeded.
When the display is on (display mode) all configured internal channels are scanned every second.
In the pure measuring mode (display off) the configured analogue measuring channels are
measured, depending on the set measuring cycle ( 1 second to 1 hour). The digital measuring
channels are measured every second.
The following figures will make clear the process of the measuring value acquisition:

5 DATA OUTPUT
On principle, there are three interfaces existing at the datalogger for the data output:
serial interface COM1 (RS232/RS485)
serial interface USB
SD-Card (Secure Digital memory Card)
With the serial interfaces COM1 and USB it is possible to query the data of the datalogger via a
cable from another computer. Via the both serial interfaces it is possible to wake-up the datalogger
(Display on), with sending a byte, therefore it is not necessary to wake-up with the "<∇>"ON -key.
The serial data output can be carried out manually (only COM1) or by remote-control (ref. to chap.
5.5 for commands).
For the reading out of data you can use a usual terminal program (e.g. “Terminal” of WINDOWS,
general settings for COM1see following Table 6). For communication via USB also a terminal
program can be used, but here a configuration is not necessary (ref. to chap. 5.4)
The serially transmitted data are output as ASCII-files (clear text). Thus, you are in a position, to
see your data records with word processors, as well, to process them and to print them out.
Herewith, you are also in a position to follow up your data via the ASCII-interface with standardsoftware such as spread sheet, data bases etc.
Furthermore it is possible to upload a firmware over COM1.
The data written on the SD-Card are saved in the same ASCII form as over the serial interfaces.

Serial (COM1):
As above but without SD-card in socket (number 2 and 9 do not apply).
Additional information’s for the using of SD-Cards:
The data files are stored on the SD-Card in the following tree structure:
The data on a CD-Card is always written into the “00”-file. If a “00”-file is present in the subdirectory
the datalogger tries to append only the new data. Whenever the “00”-file is greater then ten million
bytes, the “00”-file is renamed to a not existing “01”- till “99”-file. Unless the renaming is possible,
the output of the data will be breaked.
Remarks:
The datalogger do not delete any data on the SD-Card.
The user is responsible to use a SD-Card with enough free memory and the
deleting of the old “01”- to “99”-files.
The write-protect tab of the SD-Card is not used by the datalogger.
We strongly recommend to backup the data on alternative media.
Do not eject the card while writing the data. Press the “ENTER”-Key for breaking
the output.
Liability is excluded for loss of data.
Refer to chapter 5.2 for recommended SD-Cards.

5.2 RECOMMENDATIONS ON SD-CARD
To display the so-called “Card Identification Register”(CID: MID, OID, PNM, PRV) of the SD-Card
refer to chap. 3.1 (Baudrate COM1 / SD-Card). The data of the CID is necessary to differ the
cards, since the label on the card is normally of no relevance.

5.4 USB
For the communication via USB it is required to have a VCP (Virtual COM Port) driver on the used
PC. Virtual COM port drivers cause the USB device to appear as an additional COM port available
to the PC. Application software can access the USB device in the same way as it would access a
standard COM port.
The driver is available from FTDI (FT245R): http://www.ftdichip.com/Drivers
In addition installation guides for several operating systems can be downloaded from there.
The USB cable between PC and datalogger is a common so-called AB-plug-cable.

The data are output in tabular form with fixed telegram length. Separator is at least one space
(ASCII 32). Lines are concluded with "CR LF". Decimal separator is the point. Erroneous values are
marked by one or several "?" respectively “!”. Non-configured internal channels are marked by one
or more “-“. The end of the serial (COM1 and USB) data output is identified with the End Line (not
on SD.Card, ref. to chap. 5.6.3)
Remark:
The date and time in the data line refers to the end of the measurement.
