Fieldgate FXA320, FXA520
4 Endress + Hauser
Communication interface
Internet connection If the Fieldgate dials into the Internet permanently via an Internet Service Provider, it is also possible for several
users to access the Fieldgate simultaneously when using an analogue/GSM version. The other advantage is that
the respective user does not require a modem as a receiver at the work place.
Ethernet The 10 Base T Ethernet interface with RJ45 plug-in connection can be connected to the local network using a
hub or switch. A standard network cable is used for this. In Ethernet operation, you always have access to the
Fieldgate with a standard web browser, since the device is constantly available in the network. Several PCs can
access the Fieldgate simultaneously.

Telephone network
(analogue)
The Fieldgate is connected to the available telephone network via an RJ11 (PSTN) plug connector. This form
of communication is always a point-to-point connection and only one PC can communicate with the device at
any one time. In this configuration, the Fieldgate has to be selected before each access, so that it is ready for
online operation. For example, the Windows internal telecommunications network can be used for dialling.
After this, the Fieldgate can be accessed with a standard web browser (e.g. Internet Provider).
The Fieldgate is also capable of dialling itself into a central server, in order to deliver periodic measured values
for example. Here, it is also possible to transfer the measured values via the Internet using an Internet Service
Provider.
