Hello,
 Tank's a lot for your attention with my problems
The hardware configuration would be :
1. seismometer - signal conditioning - adc - PC industrial + hard disk -GPS.

2. solar panels - charging-12 VDC (battery)-PC (industrial) - etc.

We have short period seismometers model SD-120 and signal conditioning
produced
by Katsujima co, ltd.

We planned to use :
1. ADC type PCL 812 or PCL 818 etc from Advantech co.ltd or another ADC
card.
2. PC industrial : type PCM -5862/ max. power requirements  7 A @ 5 V
from Advantech co.ltd. or type PCM-5892 / power supply voltage + 5 V
and typical power requirements : + 5 V @ 4.2 A from AAEON co. ltd.
3. GPS from where ? I don't know yet exactly.
4. My we are going to chance the signal conditioning.
I would like to let me know  your suggestion about hardware  we have
choosen or do you (psn-ers) have another idea. Using hardware mentioned
above do you have an idea any compatible software for aquisitions and
analysis.
