Hi again,
   
  Thanks John and Alan for your quick response. 
   
  I absolutely agree about the cost..! Even being in the "low cost" range of NI devices, it is not cheap at all. But having it at hand I wanted to consult you just in case.
   
  Yes, I have got involved with the Dataq modules in the past for other application and they are no comparable in cost and very straight forward, but I would like to use a higher resolution if possible (let's say, 16 bits). 
   
  In that sense, in case I were going to design the AD card, what should be the serial data at the output to properly interface with AmaSeis?
   
  Should it already integrates UTC information (taken, lets say, from a GPS), or only the data measured from the filter?
   
  Many thanks again,
   
  Alex

  No, AmaSeis does not support the National Instruments USB 6009. The DATAQ devices are very cheap. Why not use one of them?

On laptop computers with only USB ports, we've had success using a 
USB to Serial adapter.  They are not very expensive.  This works when 
the ADC is of one of the types the AmaSeis knows about.

Each ADC has a unique format that AmaSeis must know about.  I'll bcc 
Alan Jones to see if he knows about the NI 6009 ADC.

Cheers,
John
