    Hello Shmuel,

    Yes this is possible, what you will need to do is use the slave alias registers in the datasheet to alias the similar address on each remote bus. Your procedure should look something like the following:

    1. Set register 0x4C to write to RX port 0 register page.

    2. Set register 0x5D to address of remote device

    3. Set register 0x65 to unique address on local I2C bus

    4. Set register 0x4C to RX port 1 register page

    5. Repeat for all four port register pages but choosing register 0x65 to be something totally unique each time.

    Regards,

    Nick
