VISA Serial Read

[raddack]

Hi ,NG!

I've got a problem concerning the VISA Serial Read VI:

I have to transmit binary data from a ?C to the PC. That means I don't
transmit ASCII characters. Some strings are also transmitted but that's
not the point.

While the ?C tries to send a binary value 0A (hex-decimal) Labview
changes the incoming byte into two bytes 0D and 0A. That means: Labview
thinks there's a Carriage Return at the serial port and changes it
into Carriage Return + Line Feed on a Wondows machine. I used Init Serial
VI and changed the termination character but without any effect...

What can I do?

please help

Thanks Radek

Radek:

If you are using LabVIEW 6.1, this should not be a problem. If you are using LabVIEW 6.0x, the implementation of the Init function is incomplete. You also need to set the VISA property Serial End Mode for Reads to None (0).
