About Serial Port Cabling

The Digi CM simplifies cabling. The RJ-45 8-pin configuration matches all

SUN and Cisco RJ-45 console port configurations, enabling CAT 5 cabling

without pinout concerns. Three DB-25 and one DB-9 adapters come in the

package. A DB-25 male, a DB-25 female, and a DB-9 adapter support console

management applications. A DB-25 male adapter provides a modem

connection. See the cable adapter information that follows later in this chapter.

Note: The cable length restrictions common to RS-232 cables apply to the Digi CM

serial cable as well.

Serial Port Pinouts

The Digi CM uses an RJ-45 connector for serial ports. Pin assignments are

listed in the following table.
