Convert pulse won't route to rtsi bus

[mhfracis]

I am trying to share a Convert pulse and a StartSync signal among several NI-6115 cards.  I can get the StartSync pulse to route, but not the Convert.  I am using the Route Signal vi with AI Convert as the signal source and RTSI 1 as the Signal Name.  Any ideas about what i'm doing wrong?

Hi mhfracis-

The reason you can't route the convert clock with your 6115 cards is because there is no convert clock.  S Series cards are simultaneous sampling cards that only make use of scan clocks because there are seperate ADC's per channel.  Therefore there is no need to include a convert clock.

Hopefully this helps-

I need two clocks for my analog to digital conversion, a trigger and a sample clock.  The sample clock is what i'm having trouble getting to go through.  It's hooked up to the PFI2 input, when I use the PFIn as the signal source and 2 as the signal source line number, i get a 10003 errror.  When I used the AI Convert, I didn't get any errors, but the sampling was wrong.

Hi mhfracis-

How are you attempting to route the scan clock from your external pin?  As I mentioned before, there is no AI Convert with the 6115 so it will not be helpful to you.  Are you simply trying to trigger two cards and have them share a sample clock?  Another picture of your code would be helpful.

Thanks-

I am trying to share both a sample and a trigger between two cards.  I just don't want to externally wire up several cards.  I am new to using the rtsi bus, so there may be a better way.  The NI-6115 vi is what I usually use for a single card, the rtsitest2.vi is what I spoke about above.

Thanks

Hi mhfracis-

I found this example that shows how to sync two boards' scan clocks over RTSI.  It should work well for S Series.

You may also want to check out NI-DAQmx- it is considerably easier to work with in situations like this.  The LabVIEW shipping example "Multi-Device Synch-Analog Input-Cont Acquisition.vi" shows how to do this in LabVIEW 7.x.  Check out the NI Example Finder (Help>>Find Examples) and browse to Hardware Input and Output>>DAQmx>>Synchronization>>Multi-Device.

Thanks-
