1.3 Interfaces
The Ethernet Modbus interface offers the
same form of communication with a data
acquisition system as does a serial interface.
Furthermore this interface enables to connect
the analyzer to a network, providing web-
browser access.
This interface is electrically isolated from the
unit’s electronic components and enables
the construction of a network of several ana-
lyzers.
All supported Modbus parameters are listed
in chapter 9.
Information about web-browser access is
provided in chapter 7
1.3.3 Modbus Interface, Ethernet
Fig. 1-4: Ethernet Interface Marking
A serial interface with the Modbus protocol
allows communication with external data
acquisition systems. The interface enables
the exchange and modication of measure-
ment and analyzer signals, analyzer status
monitoring as well as remote activation of
procedures.
The serial interface is electrically isolated from
the unit’s electronic components. RS 485 fa-
cilitates the construction of a network of seve-
ral analyzers. RS 232 interface only supports
communication between two end devices.

Note!
All analyzers provide 2 Ethernet connectors:
the upper marked "2" is congured to be used
for network connection. The lower, marked "1"
is for service purpose only!
Simultaneously connecting Ethernet and se-
rial interface is not supported!
1.3.5 USB Interfaces
Fig. 1-6: USB Interfaces
Two USB connectors enable connecting
• storage devices to the bigger port for
external data and analyzer conguration
storage
• external computers to the smaller Mini
USB port.
Chapter 7 provides more information on how
to use USB ports.
