FIGURE 90 Console port pin and signalling details
Most PC serial ports require a cable with a female DB-9 connector. However, terminal connections
will vary, requiring a cable with either a DB-9 or DB-25 connector, male or female.
Serial cable options between the BigIron RX Series chassis and a PC or terminal are shown in
Figure 91.
NOTE
As indicated in Figure 90 and Figure 91, some of the wires should not be connected. If you do
connect the wires that are labeled “Reserved”, you might get unexpected results with some
terminals.
