Console port connector
A DB-9 (female) connector is used for console connection. The console port has a stan-
dard RS-232 DCE interface, and utilizes the following settings: asynchronous mode,
9,600 baud speed, 8 bits per character, 1 stop bit, no parity. Use a direct cable for connec-
tion to a PC COM port.
!
An RTS signal from the managing terminal to the device console port must
be provided when connecting the console.
It is recommended to use the following cable diagrams:
