From the Basler A601f-HDR user manual: "Power must be supplied to the camera via the IEEE 1394 cable. Nominal input voltage is +12.0 VDC, however, the camera will operate properly on any input voltage from +8.0 VDC to +36.0 VDC as specified in the IEEE 1394 standard. Maximum power consumption for the A601f-HDR is 1.7 W at 12 VDC. Ripple must be less than 1%." A PCI slot has a single +12V pin. I don't know what its current and ripple ratings are, whether PCI devices share a power budget on the +12V rail. (PCI also has got +3.3V, +5V, -12V power rails. The Agere FW323 link and phy is a 3.3V powered device, so it is at least unlikely that the 1394 controller card itself uses the +12V rail for anything else besides 1394 bus power.) -- Stefan Richter -=====-==-== =-== ---== http://arcgraph.de/sr/ |
