IE-CS(T)-2TX-xRS232/485 Web Console Configuration
5-12
TCP alive check time
Setting Factory Default Necessity
0 to 99 min 7 min Optional
0 min: TCP connection is not closed due to an idle TCP connection.
1 to 99 min: the IE-CS(T)-2TX-xRS232/485 will automatically close the TCP connection if there is no TCP
activity during this given time. After the connection has closed, the IE-CS(T)-2TX-xRS232/485 will start
“listening” for another Real COM driver connection from another host.
Max connection
Setting Factory Default Necessity
1, 2, 3, 4, 5, 6, 7, 8 1 Required
Max connection is usually used when the user needs to receive data from different hosts simultaneously. The
factory default is 1, this means that only one specific host can access this IE-CS(T)-2TX-xRS232/485, and the
Real COM driver on that host will have full control over the port.
Max Connection 1:
Only a single host’s Real COM driver can access the specific IE-CS(T)-2TX-xRS232/485 serial port.
Max Connection 2 to 8:
Allows two to eight host’s Real COM drivers to access the specific IE-CS(T)-2TX-xRS232/485 serial port at the
same time. When multiple hosts’ Real COM drivers access the serial port at the same time, the COM driver only
provides pure data tunneling without control ability. This means that the serial port will use the parameter of
the firmware’s settings and not those of your application program (AP).
Application software that is based on the COM driver will receive a driver response of “success” when the
software uses any of the Win32 API functions. The firmware will only send the data back to the driver on the
host.
Data will be sent first-in-first-out when the data is received by the IE-CS(T)-2TX-xRS232/485 from the
Ethernet interface.
ATTENTION
When "Max connection" is set greater than 1, this means that the IE-CS(T)-2TX-xRS232/485 will be using a
“
multi connection application” (i.e., up to eight hosts are allowed access to the port at the same time). When
using a multi connection application, the IE-CS(T)-2TX-xRS232/485 will use the serial communication
parameters set in the console. All of the hosts connected to that port must use the same serial settings. If one
of the hosts opens the COM port with parameters that are different from the IE-CS(T)-2TX-xRS232/485’s
console setting, data communication may not transmit properly.
Ignore jammed IP
Setting Factory Default Necessity
No or Yes No Optional
If you select “No” when Max connections is > 1 and the serial device is transmitting data, in the event one of
the connected hosts is not responding, the second group of data will not be sent until all the data from the first
group has been successfully transmitted. If you select “Yes” for “Ignore jammed IP,” hosts that are not
responding will be ignored, but the data will still be transmitted to all the other hosts.
