Using cabling provided by Tritech International Ltd it is possible to connect the
Ethernet Port K or Port L into an IT infrastructure also (if for example the Gemini
Sonar is on the other side of a network hub or switch). These cables are designed
such that the power output from the connector is disabled so it is safe to connect into
a router or other network device.
