Add carriage return when communicating via USB

[Chknrckd]

Hi all,

so i've run into a problem where i need to add a carriage return (\r\n) to the end of all my commands in my VI.  I've been trying to figure out how to do this.  I found this http://digital.ni.com/public.nsf/allkb/862567530005F09C862565BE005AB500 , which gives a general idea of how do such a thing, but that is for serial connections.  

I made a property node, with TermChar En set to True, and TermChar set to '5'.  what do I hook up 'reference' to, because if I connect it to my resource name in my VI, the property node turns into the device-specific node, with different inputs/outputs.

Any ideas?

use string concatenate with a second string that contains CRLF or in /mode /r/n

what strings would i concatenate though, since I need to add the return for every command

I think a better way to phrase my question is, how do I go about adding that to all the commands?  I'm new to labview so it would be great if you had a step-by-step or a screenshot to help

Hi

You now probably call a vi that sends data to the usb port.

Replace that vi by a subvi that does the same but also adds the CRLF combination before sending.

well what I am doing is running the example VI that came with the drivers.  The example VI's just goes down and calls a series of VI that came with the labview drivers, so I'm not sure if i can (or how) get to the part thats writing to the USB.

Is there something I can add to the main VI which would add CRLF to all the write strings?

Hi

Which instrument driver are you talking to, maybe I can have a look at it.

I'm using a sorensen xg300 DC power supply.  Here is the download link to the drivers for that series of power supply:
