Cabling the LX Series
Modular Adapters (RJ-45 to DB-25)
You can obtain adapters with male and female DB-25 connectors from
MRV Communications. These adapters direct signals from the RJ-45
connector on the cable to the correct pin on the DB-25 connector. Figure 22,
Figure 23, and Figure 24 show how devices are cabled when you use these
adapters.
