C7943CA
Flat panel sensor C7942CA, C7943CA I System requirements T o operate C7942CA and C7943CA Flat Panel Sensors at full performance, the following system and peripherals are required. PC: IBM compatible PC running on Windows 98 or later operating system Digital frame grabber card: Monochrome 16 bits or more, pixel clock 16 MHz or more, RS-422 interface synchronous signal (See the frame grabber manual.) The National Instruments IMAQ PCI-1424 (NI parts No. 777662-01) frame grabber with optional memory 64 MB (NI parts No. 920130-64) has been verified to successfully acquire 12-bit digital images from both C7942CA and C7943CA. The IMAQ PCI- 1422 (NI parts No. 777959-01) also acquires satisfactory images from C7943CA. Y ou can utilize the demonstration software that comes with the frame grabber as a simple viewer, to acquire and save an image. T o do so, refer to the frame grabber user’s guide for how to use the camera information file for the demonstration software. plug at one end and open at the other end; 2 m; see T able 2.) comes supplied with C7942CA and C7943CA. An optional 36-pin cable for interface with the 36-pin receptacle (see T able 1) on C7942CA and C7943CA is also available for synchronous signal input, video output and external control. The voltages described above are specified at the flat panel sensor side. The impedance of the power cable attached with the flat panel sensor is low enough but it causes 0.1 V approx. drop. Therefore the voltage at the power source side should be set 0.1 V higher than the voltage specified above. Table 1 Pin assignment of 36-pin receptacle Pin No. Signal Pin No. Signal
