- This card was obviously never intended to leave the Windows world,
- since it lacked all kind of hardware documentation (except for cable
- pinouts, plug and pray has something to catch up with yet).
-
- With some help from our swedish distributor, we got the Windows sourcecode
- for the card, and here are the findings so far.
-
- 1. A good document that describes the PCI interface chip is 9080db-106.pdf
- available from http://www.plxtech.com/products/io/pci9080
-
- 2. The initialization done so far is:
- a. program the FPGA (windows code sans a lot of error messages)
- b.
-
- 3. Analog out seems to work OK with DAC's disabled, if DAC's are enabled,
- you have to output values to all enabled DAC's until result appears, I
- guess that it has something to do with pacer clocks, but the source
- gives me no clues. I'll keep it simple so far.
-
- 4. Analog in.
- Each channel in the scanlist seems to be controlled by four
- control words:
