"VISA Read" doesn't read

-) Yes indeed DCON is for ICP Modules. I use ICP I-7018.

What I write in hyperterminal is "$01M" then I press enter. And get a good answer.

For Labview what I did is convert $01M to hexadecimal and then get the checksum here (http://easyonlineconverter.com/converters/checksum_converter.html) and I get 2E. 

So I should convert 2E in hexadecimal to 3245(ASCII table)? 

In the manual it is written to use termination char 0x0D--> so in my example I write 13 in "termination char" block and set Enable Termination to TRUE.

If you are able to enter $01M and hit enter in Hyperterminal and it works, then you aren't sending any checksum character(s).  So remove it (them).

Look at page 73 of your manual.  It says the checksum is needed when the checksum setting is enabled.  Apparently it isn't in your case if Hyperterminal works.

End your message with \r.  Set your Visa Serial Configure to enable the termination character and be 0D (hex display) or 13 (decimal display).  Then your original VI will work.

If the checksum was enabled, then you'd send the ASCII characters "2" and "E" in the message.

It doesn't work. I have changed the .vi as it should be but it doesn't work well. My hardware is ok because I checked with hyperterminal and with a SW provided by ICP.

Maybe is my block "string to write" that doesn't send what I think i'm sending?my vi

You didn't but the termination character at the end of the message you are sending.

Change the "string to write" to \codes display.  Add \r ad the end of it.

For style points, in your block diagram, move the terminal for the termination character over to the left.  You have your wire running backwards.  In the image it looks more like an indicator than the control that it actually is.

OK now it works!!!

So the problem was I wasn't using "\ Codes display" in my Write string.

Now i get the answer and timeout error (but i think this is because of the "Simple error handler" block. I will get rid of it and thats all.

Thank you all for the help!!

I'm glad to hear it.

PS:  It would be kinder if you marked the message that provided you the solution rather than your own "it worked" message.

Your Enable Termination Char (T) boolean is set to False. This may be the reason that you are still getting a timeout expired error. Try setting it to True.

You know I didn't even notice that because the weird pink color had me thinking it was pressed.
