4.3.1 Fieldgate Analog
Fieldgate Analog is connected to a public telephone network (PSTN) via the RJ11 socket in its front

the connection to the telephone network socket.

4.3.2 Fieldgate Ethernet
Fieldgate Ethernet is connected to the network card of a computer via a crossed Ethernet cable with
RJ45 connectors or to an Ethernet network via a switch or hub and a standard Ethernet cable with
RS45 connectors. Since the transmission rate is 10 MB/s it is recommended that a switch is used
in preference to a hub.

4.3.3 Fieldgate GSM
Fieldgate requires an GSM external antenna, which can be purchased from Hauser as an
accessory. The antenna cable plugs into the socket on the front of Fieldgate and must be mounted
outside of any control cabinet or field housing. In areas of poor GSM reception, it is advisable to first
test the communication before permanently fixing the antenna.
