Max connection is usually used when the user needs to receive data from different hosts simultaneously. The factory default is 1. In this case, only one specific host can access this port of the NPort IAW5x50A_IO series device server, and the Real COM driver on that host will have full control over the port. Max. connection = 1: Allows only a single host's Real COM driver to open the specific NPort IAW5x50A_IO series device server's serial port. Max connection = 2 to 8: Allows 2 to 8 hosts' Real COM drivers to open the specific NPort IAW5x50A_IO series device server's 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. The serial port parameter will use the firmware settings instead of getting the settings from your application program (AP).
