NE-4100’s serial ports provide a 16-byte FIFO both in the Tx and Rx directions. Disable the FIFO setting when your serial device does not have a FIFO to prevent data loss during communication.

TCP Server 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: NE-4100 automatically closes the TCP connection if there is no TCP activity for the given time. After the connection is closed, NE-4100 starts listening for another host’s TCP connection.

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: NE-4100 automatically closes the TCP connection if there is no serial data activity for the given time. After the connection is closed, NE-4100 starts listening for another host’s TCP connection.

This parameter defines the maintenance status as Closed or Listen on 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 value of inactivity time is set to 0, the current TCP connection is maintained until there is a connection close request. Although inactivity time is disabled, the NE-4100 will check the connection status between the NE-4100 and remote host by sending “keep alive” packets
