NPort W2150A/W2250A Series Web Console: Serial Port Settings
8-14
Inactivity time
Default 0 ms
Options 0 to 65535 ms
Description This field specifies the time limit for keeping the connection open if no data flows to or
from the serial device.
0: The connection will remain open even if data is never received. For many applications,
the serial device may be idle for long periods of time, so 0 is an appropriate setting.
1 to 65535: If there is no activity for the specified time, the connection will be closed.
When adjusting this field, make sure that it is greater than the Force transmit time.
Otherwise, the TCP connection may be closed before data in the buffer can be transmitted.
Ignore jammed IP
Default Disable
Options Disable, Enable
Description This field specifies how an unresponsive IP address is handled when there are
simultaneous connections to the serial port.
Disable: All transmission will be suspended if one IP address becomes unresponsive.
Transmission will only resume when all hosts have responded.
Enable: Data transmission to the other hosts will not be suspended if one IP address
becomes unresponsive.
Destination address 1 to 4
Default
Options IP address and port (e.g., “192.168.1.1” and “4001”)
Description This field specifies the remote host(s) that will access the attached device. At least one
destination must be provided. This field supports the use of domain names and names
defined in the host table.
ATTENTION
In TCP Client mode, up to four connections can be established between the serial port and TCP hosts. The
connection speed or throughput may be low if any one of the four connections is slow, since the one slow
connection will slow down the other three connections.
Designated local port 1 to 4
Default
Options 1 to 65535
Description This field specifies the TCP port number that will be used for data transmission with the
serial port.
