NPort 6000 Series User’s Manual Configuring Serial Port Operation Modes
7-26
SSH
TCP alive check time (default=7 min): The TCP connection will be closed if there is no TCP
activity for the specified amount of time. If this is set to 0, the TCP connection will remain open
even if the connection remains idle. For socket and device control modes, the NPort 6000 will start
listening for another TCP connection from another host after the connection is closed for being
idle.
Inactivity time (default=0 min): This field specifies how long the NPort 6000 will wait for
incoming and outgoing data through the serial port before closing the TCP connection. The TCP
connection is closed if there is no incoming or outgoing data through the serial port for the
specified Inactivity time. If this field is set to 0, the TCP connection is kept active until a
connection close request is received.
ATTENTION
Inactivity time should at least be set larger than that of Force transmit time. To prevent the
unintended loss of data due to the session being disconnected, it is highly recommended that this
value is set large enough so that the intended data transfer is completed.
Primary and Secondary host address: If specified, the fields designate permanent hosts to which
the terminal will always be connected.
SSH TCP port (default=22): By default, the SSH TCP port number is set to 22, which is the
default SSH port number.
Quit (default=(^E) 0x05): This field configures the quick key used to disconnect the link between
the current terminal session and the remote host. For binary communication, it is unnecessary to
define the quit key.
Break: This field defines the Host key for sending the break signal. For binary communication, it
is unnecessary to define the break key.
Authentication type (default=None): This field allows you to configure the method used, if any,
to verify a user’s ID and authorization.
