NXC-VAI4 Programming Questions

in AMX Hardware
To begin, I am in the process of programming an NI-4100 with an NXC-VAI4 card installed in the first card slot. This card is intended to control the focus and zoom on a Cannon lens. The first dip switch is on and the others are off for the card frame dip switch set. Under ?DEFINE_DEVICE? I have declared the card as a device as: ?dvLensCont_NI = 13:1:0?. I assume this is correct.

The questions that I have are: How do you calibrate this device? What commands do I use to initialize it? And, what commands do I use to send zoom and focus values to the lens?

Thanks for the help.

    Have you read through the documentation?

    Here is a link to the product page:

    http://www.amx.com/products/NXC-VAI4.asp

    And here is a link to the manual which is found on the above page. The manual lists the SEND_COMMANDs along with the Levels and Channels available for this device:

    Welcome to the forum.

    Yes I did. However, the documentation is limited. Since I am relatively new to AMX programing I was hopping to get a more in-depth discussion on using this card. Please note, while I am new to AMX I do have 15 plus years of programming experience with Microsoft's Visual Basic and recently the .NET environment. So, if anyone could provide in-depth answers to the questions I posted, It would be greatly appreciated.

    Search the AMX Product Information (PI) database.
    It can show you much information about every AMX device :)

    Good luck!
