V1.0

CONNECTION TO THE LOCAL NETWORK

The instrument can be connected to the local network via Ethernet interface (optionally

Wi-Fi, on request; the two interfaces are alternatives, they cannot be used simultane-

ously).
To connect the instrument to an Ethernet network, connect the RJ45 connector of the

instrument to a socket of the local network via a standard Ethernet cable.
The instrument is preset to get a dynamic IP address from the network DHCP server. A

static IP address can be set by using the web server feature of the instrument or the

HD35AP-S application software. The IP address is displayed at the end of the list of

quantities that can be scrolled by using the “up arrow” key.
To connect the instrument to a Wi-Fi network (optional), you must first change the set-

ting of the instrument interface by connecting the instrument to the PC via Ethernet and

using the web server feature of the instrument (see the panel CONNECTIVITY >> NET-

WORK in paragraph 5.3) or the HD35AP-S software. Alternatively, connect the instru-

ment to the PC via USB through the front mini-USB connector (unscrew the protective

cap) and use the HD35AP-S software.
The instrument 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 instrument at a time) or

HDServer1 (it allows connecting several instruments 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 listening 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 instrument al-

lows 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 or the HDServer1 software 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 instrument or the HD35AP-S software.

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.
