Hi everybody,
I am trying to figure out how to control a Vötsch VT4010 climatic chamber with my PC.
I have the pdf file of the protocol (see attached file), but I don't understand the difference between 'ASCII-1' and 'ASCII-2'. Which one should I use?
As I did understand it, you can use either. You just have to decide which one. I would try the ASCII 2 protocol first, because it doesn't use any checksums. So you can use a simple terminal program to make tests.
Can anybody please send me a .vi (Labview file) to control the chamber?
Or just some good tips, 'cause it seems awkward to me to communicate with that chamber.
Sorry I can't help you with Labview Vi's. We are using Labwindows here.
You will have to look into Labviews string manipulation .vis first to build a command string from the parameters
and then send that string with the serial interface control VI to the chamber.
You probably want to control at least parameter 1 ( which is usually temperature), parameter 2 ( usually humidity)
and digital channel 1 ( usually switches the chamber on/off) . For all other values you might be able to use constant values ( except you have additional needs).
