User Manual

Delimiter 2 is optional. If left blank, then Delimiter 1 alone trips clearing of the buffer. If the size
of the serial data received is greater than 1 KB, the NPort 5200 will automatically pack the data
and send it to the Ethernet. However, to use the delimiter function, you must at least enable
Delimiter 1. If Delimiter 1 is left blank and Delimiter 2 is enabled, the delimiter function will not
work properly.

0 to 65535 ms 0 ms Optional
0: Disable the force transmit timeout.
1 to 65535: Forces the NPort 5200’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 time interval during which NPort 5200 fetches the serial data from
its internal buffer. If data is incoming through the serial port, NPort 5200 stores the data in
the internal buffer. NPort 5200 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 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 5200 should send that series of characters during a time interval less than the Force
transmit timeout for NPort 5200, and the total length of data must be less than or equal to
NPort 5200’s internal buffer size. The serial communication buffer size for NPort 5200 is 1
KB per port.
