The I²C Bus Multiplexer Cabinet selectable ports provides 5 volt power (50 mA), Clock (SCL) and Data (SDA) with 3.3 volt or 5 volt pull-ups.
 

Multiplexer Board Addressing

Each Multiplexer Board within the cabinet is controlled with messages sent to the board's common port via a host computer interface. Each Multiplexer Board has a jumper selectable I²C Bus slave address (0x40...0x4E). An alternate address range is available.
 

Multiplexer Channel Selection

Each multiplexer board has one common I²C Bus port, and 4 selectable ports. The Multiplexer Board accepts single data byte I²C Bus messages sent to its slave address. The single data byte (0, 1, 2, 3, or 4) is used by the Multiplexer Board to connect the its common I²C Bus port to one or none of its selectable channels.
