1
The bus power specification assumes that power is provided to the NI 8255R device from the host computer power supply
using the ATX power connector. If power is not supplied through the ATX power connector, camera power is supplied by the
PCIe bus and should be limited to 3 W, shared by both ports.
2
Do not draw more than 100 mA from 30 V isolated outputs. Do not draw more than 50 mA from 5 V isolated outputs.
3
To connect an IEEE 1394a camera to the NI 8255R, you will need a 6-pin to 9-pin cable or a 6-pin to 9-pin adapter.
Getting Started with the NI PCIe-8255R
