NE-4100 Series User’s Manual

Web Console Configuration

If the user wants to send the series of characters in a packet, the serial device attached to the NE-4100 should send characters without time delay larger than Force Transmit timeout between characters and the total length of data must be smaller than or equal to NE-4100’s internal buffer size. The serial communication buffer size of NE-4100 series is 1 Kbyte per port.

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: NE-4100 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: NE-4100 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 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 a connection close request is received. Although the inactivity time is disabled, the NE-4100 will check the connection status between the NE-4100 and remote host by sending “keep alive” packets periodically. If the remote host does not respond to the packets, it treats the connection as being down unintentionally. NE-4100 will then force the existing TCP connection to close.

The Inactivity time should at least be set larger than that of the Force Transmit timeout. 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.
