Setup Port Cabling and Pin Assignments
The setup port provides access to the setup port menu for the attached network
module. This menu and the setup parameters are described in the
documentation for the attached network module. Not all network modules
support the setup port. Refer to the DEChub 900 MultiSwitch Owner’s Manual
and the installation and configuration manual for the attached module for
additional information.
You can connect a setup port device (terminal device, personal computer, or
terminal server) to the setup port connector on the single-slot hub using various

9600 baud.
