Web Console Configuration

TCP Client Mode

TCP alive check time

Setting

Factory Default

Necessity

0 to 99 min

7 min

Optional

0 min: TCP connection is not closed due to an idle TCP connection.

1 to 99 min: NPort 5110 automatically closes the TCP connection if there is no TCP activity for the given time.

Inactivity time

Setting

Factory Default

Necessity

0 to 65535 ms

0 ms

Optional

0 ms: TCP connection is not closed due to an idle serial line.

0-65535 ms: NPort 5110 automatically closes the TCP connection if there is no serial data activity for the given time.

This parameter defines the maintenance status as Closed or Listen for the TCP connection. The connection is closed if there is no incoming or outgoing data through the serial port during the specific Inactivity time.

If the Inactivity time is set to 0, the current TCP connection is kept active until a connection close request is received. Although Inactivity time is disabled, the NPort 5110 will check the connection status between the NPort 5110 and remote host by sending “keep alive” packets periodically. If the remote host does not respond to the packet, NPort 5110 assumes that the connection was closed down unintentionally. NPort 5110 will then force the existing TCP connection to close.
