https://ni.lithium.com/t5/LabVIEW/Serial-625kbaud-Communication-Problem/m-p/1130785#M498787 <P>Hello</P><P>I would like to use the standard VISA write/read&nbsp; vi's to support communication with a baudrate up to <STRONG>625kbaud</STRONG> (no parity, 8bits, no data control). It works </P><P>fine with <STRONG>312kbaud</STRONG> so far but not with any higher baudrate. As interface I am using an express card which supports the desired speed and works fine with&nbsp;</P><P>an external terminal program.&nbsp;</P><P>What are the maximal baud rates supported from the VISA write/read? Is there any "special" settings which needs to be considered?</P><P>&nbsp;</P><P>Thanks in advance</P><P>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </P> Mon, 17 May 2010 14:02:53 GMT Norick_17 2010-05-17T14:02:53Z https://ni.lithium.com/t5/LabVIEW/Serial-625kbaud-Communication-Problem/m-p/1130785#M498787 <P>Hello</P><P>I would like to use the standard VISA write/read&nbsp; vi's to support communication with a baudrate up to <STRONG>625kbaud</STRONG> (no parity, 8bits, no data control).
