Operation
TM-6710/6710CL High-Speed Progressive Scanning CCD Camera
3.3.6 Progressive 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.
3.3.7 RS-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.
