|Multi-Channel I2C Bus Multiplexer Cabinet|
|I2C Bus Device Addressing Conflicts? Product Testing Problems?
We have the solution.
Our I2C Bus Multiplexer Cabinet is a multi-channel I2C Bus interface cabinet capable of delivering up to 32 independent and multiplexed I2C Bus channels.
The cabinet consists of one or more Host Computer Interfaces (USB, RS-232, or Ethernet), one or more I2C Bus Multiplexer Boards (#IP-201), power supply, power switch, power lamp, I2C Bus indicator lamps, and interconnecting cabling. All assembled into a single 19-inch 3U high rack mount cabinet.
Up to 32 separate
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
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.
The Multi-Channel I2C Bus Multiplexer Cabinet is available in many different configurations:
Part # IP-201T-YxZ-X
T = Host Computer Interface Type (U=USB, R=RS-232,
Y = Number of Host Computer Interfaces (1...8)
Z = Number of I2C Buses (4...32)
X = 5v or 3.3v Pull-Up Option (5 or 3)
