NPort 6000 Series Configuring Serial Port Operation Modes

7-22

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.
