Manual Switching

The PRO-BUF-1 can be configured manually using the ‘Mode’ pins (also referred to as ‘hard-wiring’) or via the web browser based configuration tool. Manually configuring the PRO-BUF-1 takes priority over the web configuration tool. An internet connection is not required to access the configuration tool. The factory default setting of the PRO-BUF-1 is ‘Buffer Mode 3’.

You will see from the mode table that by connecting the negative power pin to mode pin 1 will set the PRO-BUF-1 to Buffer mode 1.  In this mode, all data at input 1 is sent to all outputs.

If you need to change this to input 2, all the user needs to is move the wire connected to the negative power pin and place it in the positive power pin instead.

This process can be made even easier by placing a switch between the power and mode pins, giving the user full control over which inputs are used.
