Trying to use a Serial - USB adapter to interact with instrument

Hi there!

 

I'm pretty new to Labview and I am trying to see if I can use it to interact with one of my instruments in my lab.

 

I have this device with a serial port that - in theory - can be used to control it remotely (give commands and read data). The instruction manual shows the example of using Hyperterminal to perform the remote operations, but nothing more. I attached an extract from it with the protocol info, to help whomever is reading this.

 

I read online that you can use a USB - Serial adapter with Labview, together with the VISA drivers, to perform the same tasks. I tried to put together a VI (which I attached to this post) but as I "write" something, I don't see anything coming out in the "read".

 

What am I doing wrong? I'd like to learn more about this!

 

Thanks a bunch!

 

Paolo
