IEEE 1394 Image Acquisition with Digital I/O
IEEE 1394
Specifications
Number of ports..................................
2
These specifications are typical at 25 °C, unless otherwise stated.
Speed .................................................. 100, 200, or 400 Mb/s
Power Requirements
Physical Characteristics
Dimensions.......................................... 10.7 by 17.5 cm
IEEE 1394 bus power1 ......................... 18 W, maximum
(shared by both ports)
(4.2 by 6.9 in.)
Isolated supply2 ................................... 5 to 30 VDC
Camera interface
Weight................................................. 114 g (4.0 oz)
PCI-8254R.............................................. IEEE 1394a
NI PCIe-8255R........................................IEEE 1394b
Environment
The NI 825xR boards are intended for indoor use only.
Operating temperature ....................... 0 to 55 °C
Storage temperature........................... -20 to 70 °C
Relative humidity ................................ 5 to 90%, noncondensing
1The 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.
2 Do not draw more than 500 mA combined from the Viso pins on the 44-pin D-Sub connector.
Do not draw more than 100 mA from 30 V isolated outputs. Do not draw more than 50 mA from
5 V isolated outputs.
