Flat panel sensor C7921CA
s System requirements
To operate C7921CA 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 7 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 has been verified to successfully acquire 12-
bit digital images from C7921CA. The IMAQ PCI-1422 (NI pats No. 777959-01) also acquires satisfactory images from C7921CA.
You can utilize the demonstration software that comes with the frame grabber as a simple viewer, to acquire and save an image.
To do so, refer to the frame grabber user’s guide for how to use the camera information file for the demonstration software.
Power source: A. Vdd = +5.0 ± 0.1 V (700 mA), D. Vdd = +5.0 ± 0.1 V (800 mA), V (±7.5) = ±7.5 ± 0.5 V (±100 mA). Use of a series
power supply is recommended. (Avoid using a switching power supply.) A power cable (terminated with an FGG.2B.307.CLAD92Z
plug at one end and open at the other end; 2 m; see Table 2.) comes supplied with C7921CA. An optional 36-pin cable for interface
with the 36-pin receptacle (see Table 1) on C7921CA 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.
