Hi
To monitor the I2C bus you need to connect wires to your video capture card
I2C bus then run those wires to the parallel port of a different computer.
The main website with the program you use on the monitoring computer along
with a wiring diagram please look at:
http://warmcat.com/milksop/cheapi2c.html
However my video capture card would not work properly when using this circuit,
so if your card stops working when you plug the i2c bus into the parallel
port you could try the circuit shown on the following page:
http://ivtv.writeme.ch/tiki-index.php?page=Monitoring+I2C+Bus
To locate the I2C bus you need to download the data sheet of one of the chips
on your capture card and then look for SDA and SCL.
Obviously there is some risk in this and there is the possibility you could
damage your capture card or PC, so the best of luck.
Best Regards
