Operation
3.3.6Progressive Scanning
The TM-6710 uses a state-of-the-art CCD called a “Progressive scanning interline transfer CCD” which scans all lines sequentially from top to bottom at one frame rate 120 Hz or (60 Hz) with dual channel output. Like a non-interlace computer screen, it generates a stable crisp image without alternating lines and provides full vertical TV resolution of 484 active lines. The interline transfer architecture is also important to generate simultaneous shuttering. This is different from full frame transfer architecture which requires a mechanical shutter or strobe light in order to freeze the object motion.
The TM-6710 outputs the progressive scanned image with an electronic shutter in two different formats:
1.Progressive scanning quad speed output (normal mode)
Straightforward signal output equivalent to non-interlace VGA format (120 Hz). This is real-time CCD output through Camera Link, digital RS-644 output, and normal analog video processing into 75ohms 1Vp-p output format.
2.Partial scanning output (Rear switch.... 100 lines,.... 200 lines) TM-6710 only
By setting the switch to 100 line partial scan, the TM-6710 outputs 100 lines of video. It repeats the same rate with the fast dump blanking. The asynchronous reset and electronic shutter functions are maintained at each partial scan. When 200 line partial scan is selected, 200 lines of video are output. The partial scan maintains the same resolution as full progressive scan, although with a narrower field of view. It also maintains the same image center between partial scan and normal images.
3.3.7RS-232C (or Optional RS-485) Control and Camera Link Serial Communication
The TM-6710’s built-in microcomputer chip (CPU) can be controlled by an external RS-232C interface. The internal CPU controls TM-6710 operation mode and DSP parameter changes. Contact PULNiX for the TM-6710 software diskette. Camera Link control is implemented via Camera Link serial communication. We recommend that you use PULNiX control software (.dll), part number 69- 0062.
