Flat panel sensor C7942CA-02, C7943CA-02
s System requirements
To operate C7942CA-02 and C7943CA-02 Flat Panel Sensors at full performance, the following system and peripherals are
required.
· PC: IBM compatible PC running on Windows XP
· 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-02 and C7943CA-02. The IMAQ
PCI-1422 (NI parts No. 777959-01) also acquires satisfactory images from C7943CA-02. 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 (1000 mA), V (±7.5) = ±7.5 ± 0.5 V (±100 mA)
Please use of a series power supply. (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.), an external trigger cable (terminated with
an FFA.OS.302.CLAC37 plug at one end and open at the other end; 5 m; see table 3.) and an earth cable (AWG 18; 4 m) comes
supplied with C7942CA-02 and C7943CA-02. An optional frame grabber cable for interface with the 36-pin receptacle (see
Table 1) on C7942CA-02 and C7943CA-02 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.
Install a noise filter on the AC power input line to prevent surges on the AC line.
To supply the synchronous signal through ExtTrgGrb, apply high level of TTL to ExtTrgLemo and IntExt, or leave them without
connection. On the contrary, to use ExtTrgLemo, set high level to ExtTrgGrb and IntExt, or leave them without connection. The
earth terminal must be connected to a stable earth point to eliminate noise from surroundings.
