USB interface
The USB socket has an interface for the local connection of an AutoCon-
figuration Adapter (part number ACA 21-USB see on page 38 „Accesso-
ries“). It is used for saving/loading the configuration and for loading the
software.
V.24 interface (external management)
A serial interface is provided on the RJ11 socket (V.24 interface) for the
local connection of an external management station (VT100 terminal or
PC with appropriate terminal emulation) or an AutoConfiguration Adapter
ACA 11. This enables a connection to the Command Line Interface (CLI)
and the system monitor to be made.
The socket housing is electrically connected to the front panel of the de-
vice. The V24 interface is not electrically isolated from the supply voltage.
