16) F1_1394/F2_1394 (IEEE 1394 Connectors)
Serial interface standard set by Institute of Electrical and Electronics Engineers, which has features
like high speed, highbandwidth and hot plug. Be careful with the polarity of the IEEE1394 connector.
Check the pin assignment carefully while you connect the IEEE1394 cable, incorrect connection
between the cable and connector will make the device unable to work or even damage it. For
optional IEEE1394 cable, please contact your local dealer. IEEE1394b can approach the maximum
speed to 800Mb/S, but the speed can be achieved only when you use particular IEEE1394b cable.
