Ethernet Network Topologies
Star Topology
A star topology is a network configuration in which all the LTMT main units are directly connected to an Ethernet switch.
Point-to-Point Topology
A point-to-point topology is a network configuration in which the LTMTCUF control operator unit connects the LTMT main unit to the PC.
Example of Wiring Diagram
The wiring diagram below indicates how to connect LTMT main units installed in withdrawable drawers to the Ethernet network through the RJ45 connector and hardwired cables.
