Serial works in Hyperterminal and MAX but not Labview

[DJKleffner]

I am trying to serially communicate with a AR Kalmus Power Amplifier.
I have successfully done writes and reads using both Hypterminal and MAX, but when using LabVIEW nothing has worked yet.
The parameters are 9600 baud, 8 data bits, 1 stop bit, no parity, Flow Control is XON/XOFF.
In MAX I found out I need CR termination character (\r)

In LabVIEW I configured the VISA port to use a termination character, and that it's 0xD.
Still when I do one of the commands that worked in both Hyperterminal and MAX, it does nothing in LabVIEW.

Any ideas?
Thanks,
Daniel

A termination character in VISA is a character that stops (terminates) a reading (don't know about writing) process. If you take \0D, you'll get a single line from the device.
VISA DOES NOT ADD THIS CHARCTER WHEN WRITING!
So you have to append it to your string yaourself.

Hi Daniel:

Right click on the string you are sending into the VISA write and select '\'Codes Display. The just add \r to the end of you command.

Have a great day!
