0 to 65535 ms

0 ms

Optional

0: Disable the force transmit timeout.

1 to 65535: Forces the NPort 5110’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 5110 fetches the serial data from its internal buffer. If data is incoming through the serial port, NPort 5110 stores the data in the internal buffer. NPort 5110 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 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.

Local TCP port

Setting

Factory Default

Necessity

1 to 65535

4001

Required

The “Local TCP port” is the TCP port that NPort 5110 uses to listen to connections, and that other devices must use to contact NPort 5110. 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 NPort 5110 so that the user does not need to configure the program.
