This section lists the pinouts for the DB-9 connector and RJ-45 port jacks.

Serial (Console) Port Pinouts

The Console port is a standard male DB-9 connector, as shown in Figure 6.2.

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 FastIron GS and a PC or terminal are shown in Figure 6.3.

NOTE: As indicated in Figure 6.2 and Figure 6.3, 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.
