Termination
The wiring must be done in accordance with Figure 4-2 with 50
Ω
coaxial cable (for example inside the
enclosures, RG 58, for ship’s cabling RG 213 / U, see cabling diagrams). The network is a 10 Mbit
network.
The BNC-T plugs must be connected directly into the Ethernet Module. It is not admissible to connect the
T-plug and the network adapter by means of a coaxial cable.
Proper termination with a 50
Ω
BNC termination plug at both ends of the Ethernet line is very important.
It is not permissible to use cable with a characteristic impedance different from 50
Ω
.
If no cable is connected to the Ethernet connector, it must also be terminated.
