Cabling the LX Series

Cabling Considerations

Standard cabling items available from MRV Communications allow you to

connect to any serial device that uses male or female DB-25 or DB-9

connectors. All you need is the appropriate modular cable (crossover cable

for connecting to a DTE device, straight-through cable for connecting to a

DCE device), and the correct modular adapter (male or female DB-25

connector), which is essentially an RJ-45-to-DB25 adapter.

Serial Device Connectors

The signal assignments of the 8-pin jacks are shown in Figure 18.
