         TFG1 EVAL KIT SPEC SHEET  REV B    (c)2002 MVS




INTRODUCTION
------------

Vision is no longer limited to WINDOWS based desktop platforms!  The MVS
TFG1 is a true frame grabber capable of digitizing and buffering color and
monochrome digital camera pictures up to 640x480 pixels.  Both serial and
parallel versions (TFG1s/TFG1p) are available for use with a micro or a PC. 
It has a full frame buffer unlike competitive SX, USB, and PCI types which
store only one line at a time.  Pictures can be captured instantly and
downloaded later at any time at any rate with no blurring.  It is capable
of running at the full speed of the camera (60fps) for fast processors like
the MV1200, MV8515, or MVMEG6.  A composite analog output is available via
the RCA jack for simultaneous viewing on a CRT or LCD monitor.

The TFG1 is the only low cost true frame grabber for micros currently
available on the market.  Applications include parts inspection, alarm
systems, robotics, ID badges, motion detection, barcode, etc..  The small
"half-104" form factor and data bus mean it is easy to upgrade most
projects that are based on the ISA/104 bus standard.  The TFG1 is plug-in
compatible with MVS cards like the Mini-PC series (MVSBC1/2, MVSEX1/2) and
the RISC based Credit Card Computers (CCC1/2/3).  It is also easily
interfaced to the MVS Single Chip Computers and small third party micros
like the PIC, 8051, Stamp, Z80, AVR, HC11, etc..  The serial version is
perfect for those tiny 8 pin micros that have few bits to spare.  Demo
source code examples are provided in C, BASIC, and Assembler.

MVS has available three low cost cameras: 320x240 monochrome (MV320m),
320x240 color (MV320c), and 640x480 monochrome (MV640m).  Generally the 320
monochrome is best for pattern recognition and navigation because less data
need be tranferred and processed.  Color 320 is good when realistic photos
are required.  640 is for controllers that have lots of memory and super
fast processing ability.  Note that monochrome is 5 times more sensitive
than color (.5 lux vs.  2.5 lux).  The TFG1 can also be used with third
party camera sensors that supply parallel video with clock and sync like
those from Agilent, Phillips (Jam Cam, Nick Click), SG, Atmel, Conextant
(WonderEye), etc..  Y (mono), YUV (YCbCr), and RGB formats are supported at
QCIF (160), NTSC/PAL (320), and VGA (640) resolutions.


TRIAL RUN
---------
To test the parallel version attach an MV320m or MV320c camera module, plug
into the PC printer port (378h EPP), and connect a PC floppy power cable. 
Make sure to line up pin 1 on the card and power cable (red).  Enter
"tfgbmp" at the real mode DOS prompt to download a screen as a BMP file and
then display by typing "vpic 0.bmp" or view with WINDOWS PAINT.

The serial version can be tested by connecting to PC COM1 then entering
"tfgasm" to create a BMP file.  It can also be checked out with a simple
terminal program.  Enter "mvterm 3f8 1" then hit '`' and 't'.  Characters
coming back are not graphic but patterns can be seen which correlate with
the graphic data.  Fast PCs may use hex mode (alt-h, 2 characters/byte).
