Web Console: Serial Port Settings
7-19
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 TCP connection will be kept active until a connection close request is
received, 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.
Connection Control
must be set to “Any
character/Inactivity time” for this setting to have effect.
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 4 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 3 connections.
