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.

When Max Connection is not 1, it also means that NPort will be in “multi connection application”. In the “multi connection application”, when one of two to four host close the COM port, NPort will suspend to receive or send serial data until the host successfully close the COM port.

In multi connection application, NPort will use the serial communication parameters set in console. If the host open COM with different parameters to NPort’s console setting, data communication may not work properly

Once the NPort receives both delimiters through its serial port, it immediately packs all data currently in its buffer and sends it to the NPort’s Ethernet port.

Delimiter 2 is optional. If left blank, then Delimiter 1 alone trips clearing of the buffer. If the size of the serial data received is greater than 1K, the NPort will automatically pack the data and send it to the Ethernet. However, to use the delimiter function, you must at least enable Delimiter 1. If Delimiter 1 is left blank and Delimiter 2 is enabled, the delimiter function will not work properly.
