10 (bits) / 1200 (bits/s) * 1000 (ms/s) = 8.3 ms.
Therefore, you should set Force Transmit timeout to be larger than 8.3 ms. Force Transmit timeout
is specified in milliseconds and must be larger than 10 ms.
If the user wants to send the series of characters in a packet, the serial device attached to the NPort
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 the NPort’s internal buffer size. The
serial communication buffer size of the NPort is 1 Kbytes per port.
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: The NPort automatically closes the TCP connection if there is no TCP activity for the
given time. After the connection is closed, the NPort 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: The NPort automatically closes the TCP connection if there is no serial data activity
for the given time. After the connection is closed, the NPort starts listening for another host’s TCP
connection.
This parameter defines the maintenances 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.
