Interface Elements Description
specified period of time.
TCP alive time
If there isn't any TCP activity within schedule time, the
system will automatically send connection detection
message and check whether the TCP connection is valid. If
the reply packet of opposite side hasn't been received after
sending probe packet for 3 times, system will regard the
opposite side as down and forwardly close the
communication connection. If it is set to "0", it means that
this function is not enabled.
TCP timeout
Set the TCP timeout for the serial server's current data
communication link.
TCP Timeout > 0: If there is no data communication
between the server and client, the server and client will
break connection.
TCP Timeout = 0: When there is no data
communication between the server and client, the
server and client will keep in connection status.
Ignore jammed
Enables or disables ignore jammed connections. The
options are:
Enabled: The system ignores blocked network
connections and continues to send data to other normal
network connections.
Disabled: If the network connection is blocked or the
response is lost, the system will wait until the data is
successfully sent to all network connections before
sending the next data.
Queue access
Enable or disable queue access mode. The options are:
Enabled: Multiple hosts can send or receive data from
the serial port at the same time. The serial server
processes the communication data in the order of FIFO
(first in, first out), prioritizes requests from the first host,
and returns the response to the first host.
Disabled: Means that queue access mode is not
enabled.
Response timeout
How long to allow the serial server to respond to each host's
request, the specified time after the arrival of the serial
server and the host that the communication is complete,
