If you have set the board at a different address then you
will need to inform the software that you intend to run about the
new i/o address.
Using More Than One PC AD1200 Board.
____________________________________
_
Since each PC AD1200 card, can measure up to 16
Analogue inputs and drive 2 analogue outputs, with 8 digital i/p
and 8 digital output lines it is not generally necessary to have
more than one board installed in the PC at any one time.
However, it is possible to have many AD1200 cards, each
controlling its own set of i/o lines, in one PC.
The golden rule to follow to allow this is:- Ensure that each
PC AD1200 card is set to a different i/o address. If more
than one card is performing interrupt or DMA driven i/o
then set the IRQ and DMA jumpers to different channels.
