Daq device questions

[js777]

Hi:

I need to syncronize AO and DO on a DAQ device. 
I am thinking about USB-63XX series (for example USB-6341.), which has clocked DO, and probably cheaper than PCI series.

I have checked this example : http://digital.ni.com/public.nsf/allkb/EBD603683446EC13862575B3006A63A2 , which makes DO's clock to be AO's sampling clock.
 (the website shows that example is for PCI-series)

What I am not sure is, is this kind of shared clocks supported by most of the DAQ device with clocked digital output?

Many thanks

Hi js777,

You are referring to sample clock synchronisation as mentioned in the article in your post. This type of synchronisation is supported on most types of DAQ devices. Please refer to the following links for a list of the NI DAQ models that support this form of synchronisation:

http://zone.ni.com/reference/en-XX/help/370466V-01/mxdevconsid/synchronmxsc/

http://zone.ni.com/reference/en-XX/help/370466V-01/mxdevconsid/synchrone/

Please note that as mentioned in here: http://zone.ni.com/reference/en-XX/help/370466V-01/mxcncpts/syncsampleclock/ this form of synchronisation can result in jitter when used with multiplexed DAQ devices.

Thanks and Regards,

I have 7 sensors that their output is mv/Volt and I was said I need to have Ni 9237 module to connect the sensors. I also have a digimatic LVDT that I do not know what kind of module I need to provide for that. This is the LVDT link: http://ecatalog.mitutoyo.com/ABSOLUTE-Digimatic-Indicator-ID-C-Series-543-Standard-Type-C1198.aspx. 

I also have a kollmorgen servomotor that I was said I need to communicate b/w LabView and its programmable unit (AKD) through MODBUS. 

All in all, I need to design a DAQ that can handle 7 sensors with mv/Volts output, 1 LVDT and also can control a servomotor through MODBUS. What kind of modules, Chassis, platform and other stuff I need to build a perfect DAQ?
