Send String Text to external device using RS-232

[H2Opolo!]

Hi,

I got introduced to labview a few days ago and I was wondering if someone could help me with the following problem:

In attachment you can find the VI I am working on to try to communicate with an external device connected using RS-232.

I would like to write a string consisting of a text file with different commands to the external device.

The problem I have is that I can't write the linefeed.

I used a Serial port sniffer and notice that the text written to the RS-232 port does not contain linefeeds.

I used the termination character (\n) but this was not recognised.

I must be doing something wrong but I can't figure it out.

Can someone give me an explenation on how to get this working.

Thanks in advance!!!

What does the external device recognize as the end of a command? (Hint: you'll have to use its manual.)

 

Have you worked through the free tutorials on LabVIEW? See the end of this post.
