Ethernet wiring considerations
The sonar head and SIM use gigabit Ethernet ports. There are rules, regarding number of pairs of
wire to use, between different Ethernet ports, those rules are:
•
Gigabit to Gigabit
Need all four pairs. If only two pairs used, in an attempt to force the ports to 100BASE-T, the
ports will not negotiate and the result will be no connection. Sometimes it's not obvious if a port
is Gigabit enabled; try connecting unknown ports to a gigabit Ethernet switch and see what
speed it connects at via the status lights on the switch.
•
Gigabit to 100BASE-
T
Two pairs (green and orange on TIA/EIA-568-B wiring) can be used. Be sure to test this with a
modified patch cable (cut the brown and blue pairs) before committing to the chosen Ethernet
equipment as there may be surprises hidden in the equipment.
•
100BASE-T to 100BASE-T:
You can use two pairs.
When connecting to the SIM, use either of the AUX Ethernet ports for the sonar head Ethernet
connection.
