IMAQdx Error 0xBFF69006 Invalid Address

[eike_sommer]

Hi,

in our company we develop cameras for welding. Since last year we implement GigEVision as the machine vision interface. We got the "compliant" at plugfest. It seemed to be fine. But if I want to use our camera with Labview, we run into problems.The IMAQdx tells me, I have a problem using NI MAX and Vision Assistant. It says "0xBFF96006 invalid address".

If I check the communication with Wireshark, I can see, that NI MAX wants to write to the Message Channel Destination Adress (MCDA) and the Message Channel Port (MCP) registers. Our camera returns "Invalid Adress", because we hadn't implement an message channel and the inquired registers are a not necessary if you don't have a message channel. The "Number of message channels register" has the value 0, but NI MAX doesn't ask for this value (at the Register 0x0900) otherwise NI MAX would "know" that there is no message channel.

My Question is, how can I resolve this error!?

I hope that you can help me.
Kind regards

Eike

Are the bits indicating EVENT/EVENTDATA capability in the GVCP Capability register set? It would seem if you support no message channels those bits should be cleared.

OK. You win! That's it. I set these bits but don't support the message channel. Thanks a lot. Now it works 🙂
