5.3 Connecting to Ethernet
WARNING!
• If Fieldgate SWG70 is installed in a hazardous area Zone 2, you may only connect or
disconnect the antenna and cables in the absence of any potentially explosive atmosphere
or if the Fieldgate is not connected to the power supply.
NOTICE!
• Keep in mind that an access point of the Ethernet network has to be available. The
maximum length of the cable running from the Fieldgate to the access point is 100 m,
depending on the cable type and communication speed.
• Please note that older computers, hubs, switches or routers might not feature automatic
TX/RX detection. In this case, use a crossover cable.
• Ensure adequate strain relief for the cables.
• Pay attention to the bending radii of the cables. Do not drop below the permitted bending
radii.
5.3.1 Connecting the "Modbus" or "Modbus + OPC" versions to
Ethernet
The Ethernet cable is connected directly to the Ethernet terminal block in the Fieldgate.
