Com Grouping; Creating A Com Group - Moxa Technologies NPort 5000 Series User Manual

COM Grouping

The "COM Grouping" function is designed to simulate the multi-drop behavior of serial communication over
an Ethernet network. COM Grouping allows you to create a COM Group and redirect data from it to several
physical COM ports on NPort device servers. With COM Grouping, you will be able to control multiple
physical serial ports simultaneously by operating only one COM port.

Creating a COM Group

Follow the steps below to add multiple COM ports into one group:
Select serial port(s) for the group that you are going to create, and right-click to select COM Settings.
1.
2. Select a COM number for this COM group. You may select one of the ports already assigned to a
member of the COM Group. However, once the COM Group is configured, all of the original COM
number(s) within the group will be released simultaneously.
ATTENTION
The COM Grouping function only supports Windows NT, 2000, and later. The maximum number of ports for
each group is 32.
