MiiNePort E2/E3
TCP alive check time
Setting
0 to 99 min
0 min: The TCP connection is not closed due to an idle TCP connection.
1 to 99 min: The module automatically closes the TCP connection if there is no TCP activity for the given time.
After the connection is closed, the module starts listening for another host's TCP connection.
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 one 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 2 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.
ATTENTION
When Max connection is greater than one, the MiiNePort module will use a multiple connection application
(i.e., two to four hosts are allowed access to the port at the same time). When using a multi-connection
application, the module will use the serial communication parameters as defined here in the web console, and
all hosts connected to the port must use identical serial settings. If one of the hosts opens the COM port with
different serial settings, data will not be transmitted properly.
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.
NOTE Ignore Jammed IP is only active when Max connection is greater than 1.
Allow driver control
Setting
Enable, Disable
This option determines how the port will proceed if driver control commands are received from multiple hosts
that are connected to the port. If Disable is selected, driver control commands will be ignored. If Enable is
selected, control commands will be accepted, with the most recent command received taking precedence.
NOTE Allow driver control is only active when Max connection is greater than one.
