buffer is full or if the Force transmit time interval reaches the time specified under Force transmit timeout.

The optimal Force transmit timeout depends on your application, but it must be at least larger than one character interval within the specified baud rate. For example, assume that the serial port is set to 1200 bps, 8 data bits, 1 stop bit, and no parity. In this case, the total number of bits needed to send a character is 10 bits, and the time required to transfer one character is

( 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, so in this case, it must be greater than or equal to 10 ms.

If the user wants to send a series of characters in the same packet, the serial device attached to NPort 5110 should send that series of characters during a time interval less than the Force transmit timeout for NPort 5110, and the total length of data must be less than or equal to NPort 5110’s internal buffer size. The serial communication buffer size for NPort 5110 is 1 KB 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: NPort 5110 automatically closes the TCP connection if there is no TCP activity for the given time. After the connection is closed, NPort 5110 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: NPort 5110 automatically closes the TCP connection if there is no serial data activity
