USB DEVICE (SPECIFICATION 2.0 COMPLIANT, FULL-SPEED 12 MBPS)
Use this communication port to directly interface a PC via a USB port.
Use a standard USB cable for the connection.
To connect the instrument via the USB device port, the appropriate driver for the operating system used
must be installed on the PC. For the installation, follow the specific instructions.
FIELDBUS CONNECTIONS
As an alternative to the RS485 serial port, some of the most popular fieldbuses are available. Only
one fieldbus can be used, which must be specified when ordering.
ETHERNET CONNECTION
In the lower left part of the instrument there is an RJ45 connector for Ethernet network.
Features:
10 Mbps transmission speed
Network compatible with 10/100/1000 Base-T networks
Ethernet TCP, Modbus / TCP, UDP, IP, ICMP, ARP protocols
TCP server communication mode
Indicator LEDs (2) Ethernet line presence and communication/diagnostics
Buffer size 256 bytes
Connection Timeout Min. 30 seconds - Max. 90 seconds
Link Timeout (cable disconnected) 30 seconds

To connect to the MASTER, use an Ethernet twisted pair cable with the relevant RJ45 connector.
• The RJ45 Ethernet connection cable has a variable maximum length depending on the type of cable.
A common shielded Cat5 cable can have a maximum length of about 180 m.
• It is possible to connect the ethernet communication port directly to the PC, without switching from
other network devices (routers, switches, hubs, lan-bridges or other), but special RJ45 cables, called
“crossovers”, must be used.
• Usually the cables are “direct”, and allow the connection to network devices such as routers or hubs,
but not to directly connect two PCs (although currently there are network cards with auto-sensing
technology, which recognize the type of cable and the type of connection, allowing direct PC-PC
connections even using non-crossover cables).
• The following page shows the diagrams of the two types of cables mentioned above and the related
connection diagram.
