How-To save an images to an external firewire hard drive

[SC1]

I'm looking for some Labview samples on how-to save an images(*.avi) to an external firewire hard drive? I have a CVS-1450. I also need to know if there is any special configuration steps for connecting an external firewire hard drive to the CVS-1450.

Thanks,

SC1

Correction - I have CVS-1456 not CVS-1450.

Hello SC1,

While you cannot use AVI functions directly on your CVS, you may stream the data over a network or onto an external hard drive. You can then use the AVI VIs on a Windows machine to read and process the images (see “Can I Use the AVI Functions on My Compact Vision System (CVS)?” http://digital.ni.com/public.nsf/allkb/5C7A6FE2C2D49BE286256FE8007FDC35?OpenDocument).

To use a Firewire hard drive in this manner, you must ensure that the NI-1394 External Drive Support driver is installed (see “Firewire (IEEE-1394) Hard-drive Enclosure Compatibility with Real-Time Controllers” http://digital.ni.com/public.nsf/websearch/513DA08F2D674C6B86256F9600566D80?OpenDocument). The driver and instructions for configuring the system are here: “NI-1394 External Drive Support” http://zone.ni.com/devzone/cda/tut/p/id/3690

I hope this helps you out.

David,

Thanks for your reply. Now, how do i go about streaming the data over a network or onto an external hard drive? Can you point me to a LabView samples?

Thanks,

Hello SC1,

Once you have configured your system according to the “NI-1394 External Drive Support” page at http://zone.ni.com/devzone/cda/tut/p/id/3690, check out the IP address information under “Using NI-1394 External Drive Support” for instructions on how to call the drive over NI-FTP server. You can then send the data over a virtual server from the CVS to the FireWire drive using the “Simple Data Server.VI” example.

Alternately, you could use the “AVI Read Write With Data Example.VI” to save the .AVI file to a target drive. Simply specify the drive letter or IP address with drive letter for the FireWire device as the target.

Both examples are included in LabVIEW with NI-VISION. Please take a look at these examples and let me know if this works for your application. Thanks!

David,

Thanks again. I'll try it out as you recommended and keep you posted later.
