1 INTRODUCTION 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 (CO • Illuminance The models that measure relative humidity and temperature calculate absolute hu- midity, Dew Point, wet bulb temperature, mixing ratio and partial vapour pressure.

4 CONNECTION 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.
ETHERNET connection Wi-Fi connection 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: •...
5 WEB 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, …).
5.1 SETTINGS MENU The SETTINGS menu allows viewing the data logger general information and configuring the Modbus address, the user code, the belonging group, the logging parameters, the alarms and the units of measurement. It also allows choosing the measurements to be stored in the internal memory and displayed in real time (Monitor) and in what order.

• MEASURES panel Selection of the quantities to be displayed cyclically on the data logger display. For each quantity, a custom name can be defined. In the panel, the resolution and the unit of measurement of each quantity are also indicated. The quantities available de- pend on the data logger model type.
Page 14
• 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. Enable/Disable Buzzer Upper...

If a Mapped input type is selected, additional fields appear to define the correspon- dence between the input signal and a physical quantity. Select the unit of measurement and the resolution of the physical quantity associated to the input. Enter in the fields X1, X2, Y1 and Y2 the coordinates of the linear relation between the input signal and the physical quantity: X1 = value of input signal in the first point (e.g.
5.2 MONITOR MENU The MONITOR menu allows viewing the real time measurements, both in graphic and table form. The measurements and the corresponding date/time are updated at inter- vals equal to the logging interval. The measurements acquired by the Monitor function can be saved in a log file and exported in CSV format.

Note: if the communication with the Cloud is used, the maximum number of “clients” with proprietary or MODBUS TCP/IP protocol is nine. Note: actually, the number of MODBUS TCP/IP connections that can be active at the same time is equal to the set number of sockets less one, because a socket is always kept free to accept new connection requests (if all the sockets are active, the socket corresponding to the oldest request is released when a new connection is accepted).

• EMAIL panel Setting of the e-mail account used to send data and alarms via e-mail, of the e-mail adresses of the recipients and of the e-mail data uploading modes. The data can be sent automatically at regular intervals or you can manually request the data memorized within a determined interval of time.
Page 23
In the Files section of the EMAIL panel: o Select the Periodic Upload check box to enable the periodic sending of data via e- mail, then choose the data sending interval in the Period field. The available in- tervals are: 15 min, 30 min, 1 hour, 2 hours, 4 hours, 8 hours, 12 hours, 1 day, 2 days, 4 days, 1 week.
