Serial interface
With FW > 2.03, all Marlin cameras are equipped with the SIO (serial input/
output) feature as described in IIDC V1.31. This means that the Marlin’s serial
interface 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
camera buffer and can be polled via simple read commands from this buffer.
Controlling registers enable the settings of baud rates and the check of buffer
sizes and serial interface errors.
Base address for the function is: F0F02100h.
