Destination Address

IP address and port (e.g., “192.168.1.1” and “4001”)
Description
This field specifies the IP address for the NPort at the opposite end of the Pair
Connection, and the TCP port number for communication with the serial port.
The port number must match with that serial port’s TCP port setting.
TCP Port
Default
4001
Options
0 to 9999
Description
This field specifies the TCP port to use for communication with the attached
serial device. The serial port at the opposite end of the Pair Connection must use
this port number to establish the connection.
Settings for Ethernet Modem Mode
When
Application
is set to
Ethernet Modem
, the NPort will accept AT commands such as “ATD
192.127.168.1:4001” from the serial port. A TCP connection will then be requested from the
specified remote Ethernet Modem or PC. When the remote unit accepts this TCP connection, the
NPort will return the “
CONNECT
{
baudrate
}” signal to the serial port and will then enter data
mode. Please refer to Appendix C for details on Ethernet modem commands.
TCP Alive Check Time
Default
7 min
Options
0 to 99 min
Description
This field specifies how long the NPort will wait for a response to “keep alive”
packets before closing the TCP connection. The NPort checks connection status
by sending periodic “keep alive” packets.
0: The TCP connection will remain open even if there is no response to the
“keep alive” packets.
1 to 99: If the remote host does not respond to the packet within the specified
time, the NPort will force the existing TCP connection to close.
