Asynchronous transmission mode

Asynchronous transmission mode

Asynchronous transmission mode is a mode supported by IEEE 1394 (FireWire). IEEE 1394 supports asynchronous data transmission, which includes receipt datagrams that indicate that the data was transmitted reliably to the 1394 device. Asynchronous data transfers place emphasis on delivery rather than timing. The data transmission is guaranteed, and
retries are supported. An example for an asynchronous transmission mode is the one-shot comand. All cameras receive the one-shot command in the same IEEE 1394 bus cycle. This creates uncertainty for all cameras in the range of 125 µs.
