- The DT3000 series is Data Translation's attempt to make a PCI
- data acquisition board. The design of this series is very nice,
- since each board has an on-board DSP (Texas Instruments TMS320C52).
- However, a few details are a little annoying. The boards lack
- bus-mastering DMA, which eliminates them from serious work.
- They also are not capable of autocalibration, which is a common
- feature in modern hardware. The default firmware is pretty bad,
- making it nearly impossible to write an RT compatible driver.
- It would make an interesting project to write a decent firmware
- for these boards.
-
- Data Translation originally wanted an NDA for the documentation
- for the 3k series. However, if you ask nicely, they might send
- you the docs without one, also.
