    FRStack's View Menu, Global Profile Program Launch Editor. In the editor right click on the list of programs area. The context menu will display "Add USB Relay" / ON | OFF / COM **** List. You will have to know the COM port the USB relay created. You will need to create an 2 entries, 1 for ON and 1 for OFF.  In Windows 10 run window type "device manager". in Device Manager watch the list of com ports as you plug your USB Relay in then out. you will be able to see the COM port come and go. Mine is called "USB-SERIAL CH340".
    Any "LCUS - type 1 USB relay module USB intelligent switch control" that is set by sending its COM port the following HEX sequence A00101A2 for ON and A00100A1 for OFF.
