Selecting The USB Relay Interface

By selecting the USB interface you will be sending commands through the USB port of your computer to the board.  Boards on this page are equipped with a ZUSB communications module that adds USB communications to the board.  A command consists of a few bytes of data in numerical format usually between 2 and 6 bytes.  Once the command has been received, the controller processes the command and the relay activates.
