GPIB control Visual Basic 6 comunication error

[Kalimeru]

Hi, I´m trying to communicate with my device by doing a VB 6 program.

I've added the .bas files needed, and instaled the drivers for device.

When I run Measurement  & Automation application I can find my device, and I can send messages to it, using Interactive control.

Ok, I took the example in VB (simple.zip) to try to comunicate the first time with the device, changing to the correct addresses, but I always get the following error when I send "ilclr %Dev" :

                              Unable to clear device

                              ibsta = &H8100

                              iberr = 4 <EARG>

The question is: How to know if I'm really comunicating with my device?? or What I'm doing wrong?

Thank you

Hi Calimeru,

First of all, are you sure the reference "%Dev" is correct for your device? is this the alias name of your device in max?

To know if you are communicating with your device, you can send usual commands as *idn? to see if your device answer your request.

Then, could you try using this example : http://zone.ni.com/devzone/cda/epd/p/id/2258

Let me know,
