Description of the data path
Serial interface
All Guppy cameras are equipped with the SIO (serial input/output) feature as
described in IIDC V1.31. This means that the Guppys serial interface which is
used for firmware upgrades can also 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.
