5700 transmitters in Ethernet networks

You can install the 5700 Ethernet transmitter in star, ring, or daisy-chain networks using
industrial-rated shielded Ethernet cables.
• Make sure that each cable is no longer than 328 ft (100 m).
• Connect the 5700 Ethernet transmitter to the host system via a LAN (Local Area
Network) and not a WAN (Wide Area Network).
• Follow all network security best practices.
