Real COM Mode
TCP alive check time
Setting | Factory Default | Necessity |
0 to 99 min | 7 min | Optional |
|
|
|
0 min: TCP connection is not closed due to an idle TCP connection.
1 to 99 min: NPort automatically closes TCP connection if there is no TCP activity for the given time. After the connection is closed, NPort starts listening for another Real COM driver connection from another host.
Max connection
Setting | Factory Default | Necessity |
1, 2, 3, 4 | 1 | Required |

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, and the Real COM driver on that host will have full control over the port.
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 hosts’ 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.
