MAX displays text in hex...

[michaelg]

When I communicate with my device with MAX, the scan for instruments displays the string "IPM488", but when I use communicate with instrument, it starts displaying the text in hex ascii value... "IPM488" become "49 50 4D 34 38 38". How can I make it displays the string like when using scan for intruments?

Thanks,
Michael

This is an unusual error. I'm not sure why it is that way? Could you attach a screenshot?

Here is the screenshot of the NI-488.2 Communicator with string display in hex ascii and NI Spy that displays the string correctly.

The applet scans for any character that seems to be binary data. The alphanumeric, carriage-return and line-feed characters are not considered binary data. However, the null character is considered binary. Thus any string ending with a null character is considered binary.

The solution would be to use the VISA Interactive Control (VISAIC.exe) utility instead.
