Flat panel sensor

C7942CA-22

4

To operate the C7942CA-22 at full performance, the following system and peripherals are required.

PC: Prepare a PC that meets the specifications of the frame grabber board while taking the required image processing capability into

account.

Frame grabber board: Monochrome 16 bits or more, pixel clock 16 MHz or more, RS-422 interface synchronous signal

Power source: A.vdd = +5.0 ± 0.1 V (1000 mA), D.vdd = +5.0 ± 0.1 V (1000 mA), V(±7.5 V) = ±7.5 V ± 0.5 V (±100 mA)

· 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.

· Please use a low noise series power supply. (Avoid using a switching power supply.)

· Install a noise filter on the AC power input line to prevent surges on the AC line.

· Always ground the ground terminal to avoid the effects of noise from peripheral devices.

Frame grabber board cable (sold separately, see P. 8.): For synchronous signal, video output and external control (see Table 1.)

Power cable (terminated with an FGG.2B.307.CLAD92Z plug at one end and open at the other end; 2 m; see Table 2.)

External trigger cable (terminated with an FFA.0S.302.CLAC37 plug at one end and open at the other end; 5 m; see Table 3.)

Earth cable (AWG18; 4 m)

The image acquisition software and image processing libraries are not included with the flat panel sensor.
