9.
In the AutoPatch USB Bridge Properties dialog box, select the General tab.
10. Make note of the COM port number assigned to the AutoPatch USB Bridge. This port number must
be entered when setting a connection in a software program or a terminal emulation program. The PC
will always associate a specific USB connector with the assigned virtual COM port. The PC will not
recognize the module if you disconnect and reconnect using a different COM port on the PC.
However, it will attempt to install a new virtual COM port using the new port. If completed, the new
port will be assigned a different COM number.
Important:
You must identify the virtual COM port assigned to the USB connector to enable
communication between the Control PC and the module.

USB connector on the PC that was used previously, and (4) reopen the software.
