Console Cable Pin Assignments
In a serial communications connection, generally a computer is DTE (Data Terminal

when you connect a computer to the console port. The following diagrams and chart show the
pin assignments of the console cable.
The pin layout for the DB-9 connector end of the cables is as follows.
