USB-5132 ext clock + Trig ?

Question

Hi -
We need ~20 Mhz  for 100mS  samples, 8 bit , high clock accuracy with big (>3kV) isolation. We have been looking at a USB-5132 , with an optical-fiber to USB converter and  supply 5V that floats with the source. We need it to sync with clocks to <10ppm, and while we could run PF1 from our isolated clock system, then we wouldn't have a trigger.We had been hoping to set up the 5132 to acquire whenever it saw a clock pulse, as we can gate or otherwise process our clock signals.  I see from other posts though that the 5133 won't do continuous mode so probably not the 5132, eh ? Triggering from the inputs or in software is not an option, unfortunately (would have to trigger 500mS back) Also I had been hoping to find  programming or detailed user  manuals online but don't see them.  Another option  I suppose would be a 2 ch ethernet digitizer, but the low cost and ease of use makes the 5132 attractive, as this might be the first of a bunch more. Thanks for any input.

Hi Jennifer -
The page Matt pointed to, http://zone.ni.com/reference/en-XX/help/370592​E-01/TOC6.htm , has the outline of a programming guide. Each link points to a valid page there, but I only found a bit  on those pages, e.g. 
 http://zone.ni.com/reference/en-XX/help/370592E-0​1/digitizers/step_3-configuring_your_application/
At the bottom of those pages are links to "resources" with potentially interesting and useful stuff, e.g. from that page,

as do a bunch more down the row. Some work though.  No the whole, not terribly helpful. Myself, I want linux c/c++ drivers and libraries, but if I have to I'll use (yuck) labview.
