Common to every box

Four things are true of every MUXEN box on the bus, whatever it is and whatever firmware it carries: the identifiers it answers with, how it is addressed, how it is updated, and the single system LED.

They are described here once rather than repeated in each product's manual. Where the product lines genuinely differ — and on these topics they do — each chapter gives a table of every line's answer instead of stating one as universal.

• Overview — what is here, and the product lines it covers
• The identifiers a box carries
• How a device is addressed
• Loading and updating a firmware
• The system LED

For what a particular box does — what it connects, how it is wired, how it is commissioned — go to that product's own manual under Products.
