NPort 6000 Series Configuring Serial Port Operation Modes
TCP alive check time (default=7 min): This field specifies how long the NPort 6000 will wait for a response
to keep-alive packets before closing the TCP connection. The NPort 6000 checks connection status by sending
periodic keep-alive packets. If the remote host does not respond to the packet within the time specified in this
field, the NPort 6000 will force the existing TCP connection to close. For socket and device control modes, the
NPort 6000 will listen for another TCP connection from another host after closing the connection. If TCP alive
check time is set to 0, the TCP connection will remain open even if there is no response to the keep-alive
packets.
Secure (default=Disable): If you select Enable, data sent through the Ethernet will be encrypted with SSL.
ATTENTION
When establishing a Pair Connection between two serial ports on two different NPort 6000 servers, make sure
that if one side is configured for data encryption, the other side is also set up for data encryption (i.e., both
are yes or both are no).
Destination IP address: The Pair Connection Master will contact the network host that has the specified IP
address. The port will default to 4001. Make sure the port numbers match on both the Pair Connection Master
and Slave.
Pair Connection Slave Mode
TCP alive check time (default=7 min): This field specifies how long the NPort 6000 will wait for a response
to keep-alive packets before closing the TCP connection. The NPort 6000 checks connection status by sending
periodic keep-alive packets. If the remote host does not respond to the packet within the time specified in this
field, the NPort 6000 will force the existing TCP connection to close. For socket and device control modes, the
NPort 6000 will listen for another TCP connection from another host after closing the connection. If TCP alive
check time is set to 0, the TCP connection will remain open even if there is no response to the keep-alive
packets.
Secure (default=Disable): If you select Enable, data sent through the Ethernet will be encrypted with SSL.
TCP port (default=4001): This is the TCP port number assignment for the serial port on the NPort 6000. It
is the port number that the serial port uses to listen to connections and that other devices must use to contact
the serial port. To avoid conflicts with well-known TCP ports, the default is set to 4001. Make sure the port
numbers match on both the Pair Connection Master and Slave.
