- 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:
-
- Word0:
- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
- ! | | | ! | | | ! | | | ! | | | !
- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
-
- Word1:

- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
- | | | | | | |
- +------+------+ | | | | +-- Digital input (??)
- | | | | +---- 10 us settling time
- | | | +------ Suspend acquisition (last to scan)
- | | +-------- Simultaneous sample and hold
- | +---------- Signed data format
- +------------------------- Correction offset low
-
- Word2:
- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
- ! | | | ! | | | ! | | | ! | | | !
- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
- | | | | | | | | | |
- +-----+ +--+--+ +++ +++ +--+--+
- | | | | +----- Expansion channel
- | | | +----------- Expansion gain
- | | +--------------- Channel (low)
- | +--------------------- Correction offset high
- +----------------------------- Correction gain low
- Word3:
- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
- ! | | | ! | | | ! | | | ! | | | !
- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
- | | | | | | | | |
- +------+------+ | | +-+-+ | | +-- Low bank enable
- | | | | | +---- High bank enable
- | | | | +------ Hi/low select
- | | | +---------- Gain (1,?,2,4,8,16,32,64)
- | | +-------------- differential/single ended
- | +---------------- Unipolar
- +------------------------- Correction gain high
-
- 999. The card seems to have an incredible amount of capabilities, but
- trying to reverse engineer them from the Windows source is beyond my
- patience.
