NPort 5100A Series Web Console Configuration
NPort 5100A 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 baudrate. 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 the NPort
5100A should send that series of characters during a time interval less than the Force transmit timeout for the
NPort 5100A, and the total length of data must be less than or equal to the NPort 5100A’s internal buffer size.
The serial communication buffer size for the NPort 5100A is 1 KB per port.
Local TCP port
Setting Factory Default Necessity
1 to 65535 4001 Required
The “Local TCP port” is the TCP port the NPort 5100A uses to listen to connections, and that other devices must
use to contact the NPort 5100A. To avoid conflicts with well known TCP ports, the default is set to 4001.
Command port
Setting Factory Default Necessity
1 to 65535 966 Optional
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 the NPort 5100A so that the user does not need to configure the
program.
