gpib and interface select problem

[Donkey Rubarb]

Hi,

Max gives me the following:
-primary address: 7
-secondary address: none
-gpib interface number: 1

If I try to communicate with the instrument in labview using the the gpib write.vi with "1: 7" as the address string I get error 30.
Why?

However writing to the instrument in Max is no problem.

Bye.

Change your address string to "1:7", instead of "1: 7".
