NPort W2150/2250 Plus Series User’s Manual Web Console: Serial Port Settings
7-14
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.
Max Connection
Default
1
Options
1 to 4
Description
This field specifies the maximum number of connections that will be accepted
by the serial port.
1: Only a single host may open the TCP connection to the serial port.
2 to 4: This serial port will allow the specified number of connections to be
opened simultaneously. When multiple connections are established, serial data
will be duplicated and sent to all connected hosts. Data from hosts will be sent
to the attached serial device on a first-in-first-out basis.
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.
