Description of the data path
Serial interface
With FW > 2.03, all Marlin cameras are equipped with the SIO (serial input/out-
put) feature as described in IIDC V1.31. This means that the Marlin’s serial inter-
face which is used for firmware upgrades can further be used as a general RS232
interface.
Data written to a specific address in the IEEE 1394 address range will be sent
through the serial interface. Incoming data of the serial interface is put in a cam-
era buffer and can be polled via simple read commands from this buffer. Con-
trolling registers enable the settings of baud rates and the check of buffer sizes
and serial interface errors.
Base address for the function is: F0F02100h.
