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.

The “Local TCP port” is the TCP port that NPort 5200 uses to listen to connections, and that other
devices must use to contact NPort 5200. To avoid conflicts with commonly used TCP port
numbers, the default is set to 4001.

The “Command port” is a listen TCP port for IP-Serial Lib commands from the host. In order to
prevent a TCP port conflict with other applications, the user can set the Command port to another
port if needed. IP-Serial Lib will automatically check the Command Port on NPort 5200 so that the
user does not need to configure the program.
