• The I2C interfaces in SER A and SER B are both master interfaces
If master controller transmits I2C slave 0xA0, DES A (address 0xC0), with pass through enabled, will forward the
transaction to remote Camera A. If the controller transmits slave address 0xA4, the DES B 0xC2 will recognize
that 0xA4 is mapped to 0xA0 and will be transmitted to the remote Camera B. If controller sends command to
address 0xA6, the DES B (address 0xC2), with pass through enabled, will forward the transaction to slave device
0xA2.
