Checking the Ports Assigned for the USB to RS-232 Serial
Adapter
The following procedure is an outline only and will vary according to operating system.
To check the ports allocated for the USB-RS-232 Serial Adapter proceed as follows.
1. Enter the
Device manager
of the computer:
2. Click on the Ports (COM and LPT) option to display allocated ports:
Connect the RS-232 Serial Adapter. After a few seconds four extra ports are
displayed. These are the four ports of the adapter.
3. Make a note of the COM ports allocated.
• When the USB to RS-232 Serial Adapter is connected, the PC assigns four new
ports automatically. Usually the ports are assigned in order, for example if COM1
to COM4 are already allocated in the PC, the new COM ports allocated on the PC
could be COM5, COM6, COM7 and COM8. This would equate directly to the order
of the COM ports on the adapter, that is to COM 1, 2, 3 and 4.
• If the adapter is reconnected at any time to another USB connector on the PC, the
COM port numbers can change. This means that the COM ports do not correspond
to the defined COM ports in the application. Therefore
ensure that the adapter is
always connected to the same USB port on the computer
. If another USB con-
nector is used and the COM ports change, the COM ports must be redefined.
