1INTRODUCTION
The data loggers of the HD50 series allow indoor monitoring of various physical quanti-
ties. The data loggers are available for the monitoring of:
•Temperature
•Humidity
•Atmospheric pressure
•Carbon dioxide (CO2)
•Illuminance
The models that measure relative humidity and temperature calculate absolute hu-
midity, Dew Point, wet bulb temperature, mixing ratio and partial vapour pressure.
Models with 4 input channels, with terminal header connections, are available for the
connection of standard analog sensors:
•Transmitters with 0÷20 or 4÷20 mA current output and -50÷50 mV, 0÷50 mV,
0÷1 V or 0÷10 V voltage output
•Pt100 / Pt1000 temperature sensors and K, J, T, N, E type thermocouples
•Sensors with potentiometric output
This allows extending the monitoring capability to countless other quantities, in addi-
tion to those listed above.
The versions with LCD can be equipped with a custom LCD (option L) or with a
graphic LCD (option G).
Three LEDs on the front panel indicate the status of power supply, LAN/WLAN local
network connection and alarm.
The data loggers can be connected to a local network via the Wi-Fi or Ethernet inter-
face. The data logger allows the simultaneous operation of two communication proto-
cols: proprietary and Modbus TCP/IP. The data logger manages up to 10 “TCP/IP Cli-
ent” simultaneously. If the local network is connected to Internet, the data can be
regularly sent to an FTP address, to the Cloud and via e-mail.
For each detected quantity, two alarm thresholds can be set by the user. Exceeding a
threshold is signaled acoustically, by means of the internal buzzer, visually, by lighting
the alarm LED on the front panel, and remotely, by sending alarm e-mails. An alarm
hysteresis and a delay in the generation of the alarm can be configured for each de-
tected quantity.
Thanks to the integrated web server, you can configure the data logger and view the
real time measurements from any PC, tablet or smartphone connected to the same lo-
cal network of the data logger by simply using a web browser.
The PC software HD35AP-S allows configuring the data logger, viewing the real time
measurements, downloading and viewing the data into a database. The HD35AP-S
software allows connecting one data logger at a time. If there are several data loggers
of the HD50 series in the local network, the PC software HDServer1 allows detecting
automatically all the data loggers connected to the network and the simultaneous
connection to all the data loggers, entering the data received by the data loggers into
a database, viewing the data in the database and configuring some basic parameters
of the devices (alarms, logging interval, …). The HD35AP-CFR21 software option
(available with both HD35AP-S and HDServer1) allows the protection of recorded data
and configuration in response to FDA 21 CFR part 11 recommendations.
The internal clock can be regularly synchronized with a NIST reference server.

To configure an input, open the housing of the instrument by unscrewing the 4 front
screws and set the two switches (A and B) and the two jumpers (C and D) located
above the input terminals as shown below. Next, complete the inputs configuration us-
ing the web server feature of the data logger (see the panel SETTINGS >> INPUTS in pa-
ragraph 5.1) or the HD35AP-S software (see the section Data loggers configuration >>

4CONNECTION TO THE NETWORK
The data logger can be connected to the local network via Ethernet (default) or Wi-Fi
(the two interfaces are alternatives, they can not be used simultaneously).
For the Ethernet mode, connect the RJ45 connector of the data logger to a socket of
the local network via a standard Ethernet cable.
The data loggers are preset to get a dynamic IP address from the network DHCP server.
The data loggers with LCD display the IP address (see pag. 5). For the data loggers
without LCD, the IP address can be displayed on the PC by using the HDServer1 soft-
ware, which can automatically detect the data loggers connected to the network. A static
IP address can be set by using the web server feature of the data logger (see chapter 5)
or the HD35AP-S application software.
To connect the data logger to a Wi-Fi network, you must first change the setting of the
data logger interface by connecting the data logger to the PC via Ethernet and using
the web server feature of the data logger (see the panel CONNECTIVITY >> NETWORK
in paragraph 5.3) or the HD35AP-S software. Alternatively, connect the data logger to
the PC via USB through the internal mini-USB connector (open the housing of the in-
strument by unscrewing the 4 front screws, the mini-USB connector is located to the
right of the display) and use the HD35AP-S software.
The data logger can be accessed from any PC of the local network. To download the da-
ta in a database, the HD35AP-S (it allows connecting one data logger at a time) or
HDServer1 (it allows connecting several data loggers simultaneously) application soft-
ware and the MySQL database management system (included in the HD35AP-S soft-
ware package) must be installed.
Thanks to the availability of two TCP/IP virtual ports, each of which can operate with
proprietary (for the connection with HD35AP-S software) or MODBUS TCP/IP proto-
col, and ten sockets (in total, to be divided between the two ports), the data logger
allows the simultaneous operation of two communication protocols (proprietary and
Modbus TCP/IP) and manages up to 10 “TCP/IP Client” simultaneously. The default
setting of the ports is the following:
•Port number = 5100 for proprietary protocol (8 sockets)
•Port number = 502 for Modbus TCP/IP protocol (2 sockets)
If the local network is connected to Internet, the data can be regularly sent to an FTP
address, to the Cloud and via e-mail (as attachments).
Note: if the communication with the Cloud is used, the maximum number of “clients”
with proprietary or MODBUS TCP/IP protocol is nine.
To configure the TCP/IP ports and the sending of data over the Internet, use the web
server feature of the data logger (see chapter 5) or the HD35AP-S software.
Restoring the factory LAN/WLAN configuration:
It is always possible to restore the default LAN/WLAN settings by following these steps:
1) Open the housing of the instrument by unscrewing the 4 front screws.
2) Place the short jumper over the NET RST push-button (to the left of the display)
between the “2” and “3” indications.
3) Press the NET RST push-button.
4) After the reset, replace the short jumper between the “2” and “1 (NORMAL)” indi-
cations.

4.1 HD35AP-CFR21 SOFTWARE OPTION
The HD35AP-CFR21 option allows, in addition to the features of the basic software
(both HD35AP-S and HDServer1), the protection of recorded data and instrument con-
figuration in response to FDA 21 CFR part 11 recommendations. In particular be-
come available:
•The traceability of activities (Audit Trail) performed with the software; for exam-
ple, which users connected and what changes were possibly made to the configu-
ration of the instrument.
•The management of users access for the instrument configuration and viewing of
data in the database. Each user can be assigned a different password for using the
software. There are also three levels of access (Administrator, Super-user and stan-
dard User); for each level, the allowed operations can be defined.
The HD35AP-CFR21 option works with USB hardware key to be connected to any PC con-
nected to the same local network of the PC in which the basic software is installed.
Note: if the HD35AP-CFR21 option is used, the data logger integrated web server allows view-
ing measurements and configuration, but not the modification of the data logger configuration,
because the settings changed via web server can not be traced.

5WEB SERVER
The data logger has an integrated web server through which you can configure the data
logger and view the real time measurements from any PC, tablet or smartphone con-
nected to the same local network of the data logger by simply using a web browser.
To connect to the web server, type the IP address of the data logger in the address
bar of the web browser of your device (PC, tablet, smartphone, …).
Note: the data loggers with LCD display the IP address (see pag. 5); for the data loggers
without LCD, the IP address can be displayed on the PC by using the HDServer1 soft-
ware, which can automatically detect the data loggers connected to the network.
Note: if a port number other than the standard HTTP (80) has been set in the data
logger, the port number must be specified after the IP address (IPaddress:port num-
ber).
In the web server starting window, enter the user name and the password supplied
with the data logger, then press Submit.

•ALARMS panel
Setting of the alarm thresholds for each of the available quantities. The alarm is gen-
erated if the measured value falls below the lower threshold or rises above the upper
threshold. The hysteresis and the delay time of the alarm can be configured.
The amplitude of the hysteresis is in percentage (0...100%) of the difference between the
two alarm thresholds. For example, if the hysteresis is 2%, the lower threshold is 10 °C
and the upper threshold is 60 °C, the hysteresis in °C is equal to (60-10)x2/100= 1 °C.
The alarm is generated after the set delay time (or immediately if the “no delay” op-
tion is selected). If the alarm condition disappears before the delay time has elapsed,
the alarm is not generated.

5.3 CONNECTIVITY MENU
The CONNECTIVITY menu allows configuring the network (Wi-Fi or Ethernet) and the
sending of data via e-mail, FTP or to the Cloud (if the network has an Internet con-
nection). It also allows setting the automatic clock synchronization and the time zone.
•NETWORK panel
Setting of the network interface type (Wi-Fi or Ethernet), of the protocols, of the
TCP/IP ports, of the IP address and of the DNS server address.
Note: if the data logger IP address is changed, the new address must be entered in
the web browser to connect to the web server.
If a port number other than the standard HTTP (80) is set as web server listening
port, the port number must be specified after the IP address in the web browser. For
example, if 40 is set as listening port number of a data logger with IP address
192.168.1.2, in the web browser you need to type 192.168.1.2:40.
The WLAN/LAN module has two TCP/IP ports. For each of the two ports, set the fol-
lowing:
othe protocol : select Proprietary TCP (proprietary protocol) or Modbus TCP.
othe port number : the numbers set by default are 5100 for the proprietary proto-
col and 502 for the Modbus TCP/IP protocol.
othe number of sockets of the port : the number of sockets corresponds to the
maximum number of connections that can be active at the same time through
the port. In total there are 10 sockets to be divided between the two ports
(for example, if 8 sockets are assigned to the first port, the second port can have
a maximum of 2 sockets).
