IEEE 1394 Image Acquisition with Digital I/O
IEEE 1394
Number of ports.................................. 2
Speed .................................................. 100, 200, or 400 Mb/s
Specifications
These specifications are typical at 25 °C, unless otherwise stated.
Power Requirements
IEEE 1394 bus power
1
......................... 18 W, maximum
(shared by both ports)
2
Isolated supply ................................... 5 to 30 VDC
Camera interface
PCI-8254R.............................................. IEEE 1394a
NI PCIe-8255R........................................IEEE 1394b
The bus power specification assumes that power is provided to the NI 825xR boards from the
host computer power supply via the ATX power connector. If power is not supplied through this
connector, camera power is supplied by the PCI bus and should be limited to 5 W, shared by
both ports.
