Hi!
I try to communicate with SL512EC and SIUDI-IN under BorlandDelphi 7.0. It's problem. I write in .pas:

function DasHardCommand(command: Integer; param: Integer; blok: Integer): Integer; external 'DasHard.dll' name 'DasHardCommand';

and then:

Code: Select all

Result := DasHardCommand(1,11,0);

But i have Result = 0 after this command.
I think, i must have Result = 11

What's wrong?

Hello,

Coult you try to do :
Result := DasHardCommand(1,0,0); to open the first interface
Result := DasHardCommand(101,0,0); to open the second interface
or
for i=0 i<10 i++
Result := DasHardCommand(1+100*i,0,0); to open the # i interface

If the 2 interfaces are pluged, SIUDI-IN can be the first and SIUDI-EC can be the second (or inverse !)
It's why it's better, to keep second param equal to 0
and test all the USB ports.

When you write
Result := DasHardCommand(1,11,0);
it means that you look for a SIUDI-EC as the FIRST plugged.
