0 to 99 min

0 min: TCP connection is not closed due to an idle TCP connection.

1 to 99 min: The NPort automatically closes TCP connection if there is no TCP activity for the given time. After the connection is closed, the NPort starts listening for another Real COM driver’s connection from another host.

Max Connection is usually used when the user needs to receive data from different hosts simultaneously. The factory default only allows 1 connection at a same. When Max Connection is set to 1, the Real COM driver on the specific host has the full control.

Max. Connection 1:

Allows only 1 host’s Real COM driver to open the specific NPort serial port.

Max Connection 2 to 4:

Allows 2 to 4 host’s Real COM drivers to open the specific NPort serial port, at the same time. When multiple hosts’ Real COM drivers open the serial port at the same time, the COM driver only provides a pure data tunnel without control ability. That is, this serial port parameter will use firmware’s settings, not depend on 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 data comes into the NPort from the Ethernet interface.

ATTENTION

When Max connection is set to 2, 3, or 4, this means that the NPort will be using a “multi connection application” (i.e., 2, 3, or 4 hosts are allowed access to the port at the same time). When using a multi connection application, the NPort 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 NPort’s console setting, data communication may not work properly.

Ignore jammed IP

Setting

Factory Default

Necessity

No or Yes

No

Optional

 

 

 

Previously, when Max connections > 1, and the serial device is transmitting data, if any one of the connected hosts is not responding, it will wait until the data has been transmitted successfully before transmitting the second group of data to all hosts. Currently, if you select Yes for “Ignore jammed IP,” the host that is not responding will be ignored, but the data will still be transmitted to the other hosts.
