1.11 Network Termination
The network module LEM (see Fig. 1-19) connects the analyzer with external modules via network.
RJ 45 sockets are serving for network interconnection between analyzer or platform and analyzer
modules (see Fig. 1-8, 1-13, 1-20, 1-23 and 1-31b).
It is necessary to terminate the ends of a twisted pair bus to minimize reflections (see Fig. 1-37).
Failure to terminate the bus will degrade network performance.
Termination will be done via RJ 45 connectors (see Fig. 1-36).
