WE have bought a PCI 1422 card [labVIEW 6.1, IMAQ 2.5.2,Camera Pulnix TM -1010 ] It doesn't acquire the image, shows error code " no external pixel clock". We have another PCI 1422 which is working without any problems with the same PC [ there are no settings in MAX for the camera/card which could solve this].Please suggest why this could be.
