0: Disable the force transmit timeout.

1 to 65535: Forces the NPort’s TCP/IP protocol software to try to pack serial data received during the specified time into the same data frame.

This parameter defines the interval during which NPort fetches the serial data from its internal buffer. If there is incoming data through the serial port, NPort stores the data in the internal buffer. NPort transmits data stored in the buffer via TCP/IP, but only if the internal buffer is full or if the force transmit time interval reaches the time specified as Force Transmit timeout.

Optimal force transmit timeout differs according to your application, but it must be at least as large as 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 required 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 the 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 a series of characters in a packet, the serial device attached to 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 NPort’s internal buffer size. The serial communication buffer size of NPort is 1 Kbyte per port.
