HD33[L]MT.4 - 2 - V4.1

1 INTRODUCTION

The HD33[L]MT.4 data logger is specifically designed for use in weather stations. Many types
of sensors can be connected thanks to its standard terminal header inputs. The data logger is
equipped with:

• 4 analog independently configurable inputs (0…50 mV, -50…+50 mV, 0…1 V, 0…10 V,

0…20 mA or 4…20 mA, Pt100, Pt1000, thermocouple, potentiometer, pyrgeometer).

• 2 voltage-free counting contact inputs (e.g. a tipping bucket rain gauge and a cup

anemometer can be connected).

• One RS485 port with Modbus TCP/IP (via an optional module for the connection to

an ETHERNET network) or Modbus-RTU protocol, configurable as "Master" or "Slave".

• One SDI-12 “Master” port compatible with version 1.3 of SDI-12 protocol.

• 2 voltage-free contact alarm outputs.

On request, input with M12 connector for relative humidity and temperature with NTC sensor
combined probe or, alternatively, for temperature only probe with NTC sensor.

Optional custom LCD display.

Thanks to 4G / 3G / GSM(2G) / GPRS transmission, the user will not have to remove the data
logger from its position or reach the place where the data logger is installed to download the
data measured with the PC: the instrument can send the data via e-mail or FTP and can
upload the data on an HTTP server (Cloud, for example the Delta OHM portal
“www.deltaohm.cloud”). The data logger can be controlled remotely either by sending
commands via SMS messages or by establishing a direct TCP/IP connection via mobile network
with a remote PC connected to the Internet.

For each detected quantity, the user can set two alarm thresholds (high threshold and low
threshold), the alarm hysteresis and a delay in the generation of the alarm. The overrun of the
thresholds can be signaled by alarm e-mails or SMS messages. Two voltage-free contact alarm
outputs are also available.

HD35AP-S PC software, downloadable free of charge from the Delta OHM website, allows
configuration of data logger, displaying measurements in real time both in graphical and
numerical format, data download. The data transferred to the PC are entered into a database.

The internal clock of the data logger has high accuracy and is extremely stable in the whole
operating temperature range of the instrument. It supports the automatic time
synchronization with an HTTP reference server.

The optional 12 V / 3.4 Ah rechargeable backup battery to be installed inside the case
prevents the loss of recordings in case of no external power supply. The battery charger is
integrated in the instrument. The data logger can be powered by a solar panel and is designed
to be low power: can operate for weeks even in absence of battery recharging from the solar
panel. Power supply 18…30 Vdc if the rechargeable battery is used or 7…30 Vdc (without
ETHERNET module) / 12…30 Vdc (with ETHERNET module) if the rechargeable battery is not
used.

A switched power supply output allows powering the sensors only when measurements have to
be taken.

Power supply:

To power the data logger with a solar panel, connect the panel to the +VPanel and GND terminals.
To power the data logger with a direct voltage power supply unit, (for example HD32MT.SWD),
connect the power supply unit to the +Vdc and GND terminals.

ATTENTION: connect the PE terminal to ground through the cable gland at the
bottom of the housing.

If a direct voltage power supply unit is used and the data logger is equipped with a rechargeable
lead battery, the battery can be charged by shorting the +Vdc and +Vpanel terminals (provided
that +Vdc is within the range 18…27 Vdc).

Analog inputs:

Each analog input can be configured as a Pt100/Pt1000, thermocouple, 0/4…20 mA (shunt
resistance inside), 0…50 mV, -50…50 mV, 0…1 V, 0…10 V or potentiometric input. A
pyrgeometer can also be connected.

The current input accepts any value in the range 0 to 20 mA.

The switched power supply output +Vsw2 can be used to power the sensors and can be
configured as always active, active only during measurements acquisition or always disabled (if
only passive sensors are used). When active, it has the same value as the battery voltage if
the data logger is powered by a solar panel (+Vpanel input), while it is equal to the voltage of
the +Vdc input if the data logger is powered by a direct voltage power supply unit (+Vdc input).

SWIN2 contact input: connect the output contact of the sensor between the terminals
SWIN2 and GND. The default contact state can be configured: Normally Open (NO) or
Normally Closed (NC). The open state is logged as 1, while the closed state is logged as 0. The
logged contact state depends on how long the contact remains in the non-default state during
the logging interval. If the contact remains in the non-default state for more than a given time
(configurable and expressed as a percentage of the logging interval), the non-default state is
logged. Vice versa, if the contact remains in the non-default state for less than the set time,
the default state is logged.

Example 1: if the contact default state is Normally Open, the logging interval is 30 seconds
and the time set for the contact state change is 50% of the logging interval, 0 is logged
(contact closed, non-default state) if the contact remains closed for more than 15 seconds
during the logging interval, otherwise 1 is logged (contact open, default state).

Example 2: if the contact default state is Normally Closed, the logging interval is 1 minute and
the time set for the contact state change is 10% of the logging interval, 1 is logged (contact
open, non-default state) if the contact remains open for more than 6 seconds during the
logging interval, otherwise 0 is logged (contact closed, default state).

On request, the SWIN2 contact input can be factory set up for connecting a cup
anemometer.

Serial port:

In “Master” mode, the port allows reading the measurements of the sensors with RS485
MODBUS-RTU output connected to the data logger serial port. In “Slave” mode, the data logger
can communicate the measurements detected by the sensors connected to the other inputs to
the "Master" unit of the MODBUS network.

Connect the signals DATA+ and DATA – from the network of sensors to the terminals TX+ and
TX- respectively. Connect the ground of the network of sensors to the terminal GND.

Through an optional module connected to the serial port, the data logger can be connected to
an ETHERNET network and communicate with MODBUS TCP/IP protocol.

The switched power supply output +Vsw1 can be used to power the sensors and can be
configured as always active, active only during measurements acquisition or always disabled.
When active, it has the same value as the battery voltage if the data logger is powered by a
solar panel (+Vpanel input), while it is equal to the voltage of the +Vdc input if the data logger is
powered by a direct voltage power supply unit (+Vdc input).

SDI-12 port: there is only one port, the two SDI-12 inputs are in parallel to facilitate the
connection of multiple sensors.

In “Master” mode, the port allows reading the measurements of the sensors with RS485

OUT1 / OUT2 alarm outputs: the instrument is equipped with 2 voltage-free contact alarm
outputs that can be handled automatically by the data logger or manually. When handled
automatically, the alarm conditions that activate the outputs can be configured by using the
HD35AP-S software (see the instructions of the software). When handled manually, the alarm
output states can be additionally configured via display and/or SMS commands.

WARNING:

Use the switched power supply output +Vsw only to power sensors having a maximum power
supply greater or equal to:

• the battery voltage, if the data logger is powered by a solar panel (+Vpanel input);

• the +Vdc input voltage, if the data logger is powered by a direct voltage power supply unit
(+Vdc input).

SIM holder block

7 SIM CARD

In order to use the mobile network functionalities, a SIM card enabled for data transmission
must be inserted into the data logger. The card should be requested to an operator that has an
adequate coverage of the mobile network in the place where the data logger will be installed.
To insert the card, proceed as follows.

1. Disconnect the power supply.

2. Open the housing.

3. Push the metal block of the SIM tray in the direction of the arrow OPEN, and rotate the tray

upward.

SIM card

reference

4. Insert the SIM card into its tray so as the SIM card contacts face down and correspond to

the contacts on the electronic board. The SIM has to be inserted between the metal block
and the plastic part.

5. Put the SIM tray back in place and push the metal block in the direction of the arrow LOCK.

6. Close the housing.

Through the HD35AP-S software, set the necessary information for mobile network operation:
SIM PIN, name of the APN access point, e-mail account and addresses, FTP address, telephone
numbers, data transmission mode, etc. (see section “Mobile network settings” of the software
online help).

Note: the switch located on the left of the SIM card must be set upwards. The downwards
position and the PWRKEY button are used to update the firmware of the mobile communication
module.

The connection symbol (CONN) on the display is ON when the instrument is connected to the
mobile network (the symbol blinks while connecting).

Among the information that you can scroll on display with the button in the lower part of the
data logger, there is also the strength RSSI (Received Signal Strength Indication) in dBm of
the mobile network signal received.

HD33[L]MT.4 - 19 - V4.1

8 USB CONNECTION

The data logger can be connected to a PC through the mini-USB connector located at the
bottom of the housing. Remove the connector protective cap and connect the CP23 cable.

USB connection doesn’t require the installation of drivers: when the data logger is connected to
a PC, Windows® operating system automatically recognizes the instrument as an HID device
(Human Interface Device) and uses the drivers already included in the operating system.

The data logger must be powered separately, it is not powered by the PC USB port.

When the data logger is not connected to the PC, replace the mini-USB connector protective cap
to ensure the watertight integrity of the instrument.

9 HD35AP-S SOFTWARE

The HD35AP-S software, downloadable free of charge from the Delta OHM website, allows:

• Configuring the data logger: measurements to be displayed, alarm thresholds and hystereses,

logging and transmitting intervals, date and time, etc. (see chapters “HD35ED… data loggers
configuration”, “Alarms configuration”, “GSM/3G/4G settings” and “Clock setting” of the
software online help).

• Transferring stored data to PC (see chapters “Data download” and “Data download from

FTP” of the software online help).

• Displaying measurements in real time, also in graphic format (see chapter “Monitor” of the

software online help).

• Managing the graphical representation, print and export of acquired data (see chapter

“Displaying data in the database” of the software online help).

• Calibrating the sensors (see chapter “Calibration” of the software online help).

For the connection of the data logger to the HD35AP-S software see chapter “Connection” of the
software online help.

11 TCP/IP CONNECTION VIA MOBILE NETWORK

It is possible to interact with the data logger by establishing a direct TCP/IP connection via
mobile network with a remote PC connected to the Internet.

The connection can be of two types:

1) Data Logger = Client , PC = Server

The data logger acts as TCP client and requests the connection to the PC, the PC acts as
TCP server and waits for the connection request. The server IP address (PC or Router)
must be public and can be either static or dynamic; if the IP address is dynamic, it is
convenient to register the server to a DDNS (Dynamic Domain Name System) service.

2) Data Logger = Server , PC = Client

The PC acts as TCP client and requests the connection to the data logger, the data logger
acts as TCP server and waits for the connection request. The server IP address (data
logger) must be public and static.

Connection Data Logger = Client , PC = Server

1. Open a port (port forwarding) in the Modem/Router through which your PC connects to

Internet (follow the instructions of your Modem/Router).

2. Connect the data logger to a PC USB port and perform the connection procedure with the

HD35AP-S software.

3. In the HD35AP-S software select Instruments setup >> GSM options >> GPRS TCP/IP client

settings and set the server IP address or domain name and port number (number of the port
opened in the Modem/Router).

4. Disconnect the data logger from the USB port.

5. In the HD35AP-S software select Tools >> Type of connection, select the TCP server option

and set the number of the port opened in the Modem/Router.

6. In the HD35AP-S software, select the Connect icon.

7. Send to the data logger the SMS command TCP-CLIENT-ON.

If the connection is not established within 30 minutes after sending the SMS command TCP­CLIENT-ON, the command must be sent again.

Alternatively, the server IP address or domain name and port number can be set in the data
logger without connecting the data logger to the PC and without the HD35AP-S software by
using the SMS commands TCP-SERVER-ADDRESS and TCP-SERVER-PORT.

Connection Data Logger = Server , PC = Client

1. Open a listening port in the data logger by using the SMS command TCP-LISTEN-PORT

(for example, TCP-LISTEN-PORT=2020).

2. Send to the data logger the SMS command TCP-SERVER-ON.

3. The data logger replies with a first SMS to confirm that the command has been accepted.

Wait for a second SMS with the confirmation that the TCP server functionality has been
activated and with the IP address (and port number) assigned to the data logger.

4. In the HD35AP-S software select Tools >> Type of connection, select the TCP client option

and set the IP address and port number of the datalogger.

5. In the HD35AP-S software, select the Connect icon.

If the connection is not established within 1 hour after sending the SMS command TCP­SERVER-ON, the command must be sent again.

HD33[L]MT.4 - 24 - V4.1

12 MODBUS

The complete list of MODBUS registers for “Slave” mode is shown below. Depending on the
system configuration, some of the listed registers could not be present if not significant for that
particular system (for ex., atmospheric pressure measurement will not be available if it is not
measured by the data logger). If you try to read a register that is not present, the instrument
returns the fixed value 32767.

The following conventions have been used in the tables:

o Type: b = bit, B = 8 bits (Byte), W = 16 bits without sign (Word), SW = 16 bits with sign
o (x10) = decimal value expressed as an integer (e.g., if the content of the register is 184,

the value is to be intended as 18,4).

o (x100) = centesimal value expressed as an integer (e.g., if the content of the register is

500, the value is to be intended as 5,00).

The commands for requesting units of measurement return an index according to the
correspondence indicated in the table below:

Scalar average: the average intensity is calculated as average of intensities. For the calculation of the

Wind speed when the measurement is below the minimum threshold of the sensors:

0=0 m/s, 1= threshold value in m/s

Coil description

average direction, also called “prevailing direction”, the velocity versor (unit vector having the same
direction of the velocity vector) is considered for each measurement, and the versor coordinates along the
measurement axes are calculated, then the average of the coordinates along each axis is calculated. The
two average coordinates determine the average versor and therefore the average direction.

Vector average: for each measurement, the coordinates of the velocity vector along the measurement
axes are calculated and then the average of the coordinates along each axis is calculated. The average
intensity and the average direction are those determined by the two average coordinates.

(2)

The wind direction measuring range, normally 0…359.9°, can be extended to 0…539.9° in order to avoid

the oscillation of the measurement between initial and full scale if the direction continues to slightly
fluctuate around 0° (the change 0359.9° takes place, but not the change 359.90°). If 539.9° value is
exceeded in extended mode, the output goes to 180°.

(3)

If using HD51.3D… and HD52.3D… series ultrasonic anemometers, the type of average and the wind

direction measuring range can be set directly in the anemometer.
