MiiNePort E2/E3
1 to 99 min: The MiiNePort automatically closes the TCP connection if there is no TCP activity for the given
time. After the connection is closed, the MiiNePort starts listening for another host's TCP connection.
Inactivity time
Setting
0 to 65535 ms
0 ms: TCP connection is not closed due to an idle serial line.
0-65535 ms: The MiiNePort automatically closes the TCP connection if there is no serial data activity for the
given time. After the connection is closed, the MiiNePort starts listening for another host's TCP connection.
This parameter defines the maintenance status as Closed or Listen for the TCP connection. The connection is
closed if there is no incoming or outgoing data through the serial port during the specific Inactivity time.
If the Inactivity time is set to 0, the current TCP connection is kept active until a connection close request is
received. Although Inactivity time is disabled, the MiiNePort will check the connection status between the
MiiNePort and the remote host by sending "keep alive" packets periodically. If the remote host does not
respond to the packet, the MiiNePort assumes that the connection was closed unintentionally. The MiiNePort
will then force the existing TCP connection to close.
ATTENTION
The Inactivity time should be greater than the Force transmit timeout. To prevent the unintended loss of data
due to the session being disconnected, it is highly recommended that this value is set large enough so that the
intended data transfer is completed.
ATTENTION
Inactivity time is ONLY active when TCP connect on is set to Any character.
Max connection
Setting
1, 2, 3, 4
Max connection is used when the device needs to receive data from different hosts simultaneously.
The factory default only allows 1 connection at a time. When Max Connection is set to 1, the Real COM driver
on the specific host has full control.
Max connection 1: The module will only allow one host's Real COM driver to open a connection to the
module's serial port.
Max connections 2 to 4: When set to two or higher, Real COM drivers for up to the specified number of hosts
may open this port at the same time. When Real COM drivers for multiple hosts open the port at the same time,
the COM driver only provides a pure data tunnel with no control ability. The serial port parameters will use
firmware settings instead of your application program (AP) settings.
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 data back to the driver on the host.
Data will be sent first-in,first-out when data is received by the MiiNePort from the Ethernet interface.
Ignore jammed IP
Setting
Enable, Disable
This option determines how the port will proceed if multiple hosts are connected, and one or more of the hosts
stops responding as the port is transmitting data. If you select Disable, the port will wait until the data has
been transmitted successfully to all hosts before transmitting the next group of data. If you select Enable, the
port will ignore the host that stopped responding and continue data transmission to the other hosts.
