The Relay is programmed by sending it MIDI System Exclusive programming commands from a computer with a

Upon receipt of a programming command, the Relay's MIDI indicator LED flashes rapidly for about one second to
indicate that the setting has been stored. Settings are retained after power is removed, and the unit can then be
inserted wherever it is required in your MIDI setup.
The Relay's MIDI Indicator LED will light as soon as the sending device is turned on, and flashes whenever MIDI data
passes through the unit. The Relay will respond to incoming MIDI messages according to its programmed settings.
All MIDI messages appearing at the MIDI In are passed to the MIDI Out.
