Chapter 3 Signal ConnectionsNI PCIe-8255R User Manual 3-8 ni.comCablingIEEE 1394 Camera CablesYou can connect cameras to the NI 8255R using standard 9-pin IEEE 1394cables. IEEE 1394 cables provide both a data path and power to yourcamera. You can use a 6-pin to 9-pin cable or adapter with IEEE 1394acameras to connect the cameras to the IEEE 1394b ports.I/O Terminal BlockNational Instruments provides an I/O terminal block for the NI 8255R,which can be mounted either horizontally or vertically. The I/O terminalblock breaks the signals out into easy-to-use screw terminals and comeswith a cable that connects directly to the 44-pin D-SUB connector on theNI 8255R.Note TRIG 0, TRIG 1, and TRIG 2 signals are not accessible through the standard 44- to37-pin cable and I/O terminal block.NI Vision I/O Terminal Block and Prototyping AccessoryUse the NI Vision I/O Terminal Block and Prototyping Accessory totroubleshoot and prototype digital I/O applications for the NI 8254R,NI 8255R, and the NI CVS-1450 Series compact vision system. TheNI Vision I/O Terminal Block and Prototyping Accessory providesscrew terminals for easy connections and LEDs for each signal.43 30 ISO Input 10 General-purposeinputTrigger ChangeDetector,General-purposeinput44 31 ISO Input 11 User shutdown General-purposeinput* TRIG 0, TRIG 1, and TRIG 2 are not available on the 37-pin terminal block or the NI Vision I/O Terminal Block andPrototyping Accessory. If you need access to these signals, you can get them directly from the 44-pin D-SUB connector.Table 3-2.
