How to write programs for selfdeveloped message based instruments?

[windy]

I developed a message based interface by myself, but I have no experience of developing instrument drivers with Labwindow/CVI. I want to know which commands will be sent to the instruments when power up? It's very strange that when I plug in my instrument, the light of Access of resource mamager keep on lighted and the HP-VISA Assistant can't recoganize all the instruments in the mainfram. I want to know how to let my instrument be recoganized by system. Thank you very much!

What is the VXI controller for your system? What VXI driver is running on the system? You mention HP-VISA, is your VXI controller and driver from HP or Agilent? If so, you will need to contact them on how to get your instrument recognized and working in the system.

To write your instrument driver, I would recommend using VISA commands. Message based instruments have sets of specific commands that they respond to. Generally, one would have to look in the documentation for that instrument to determine the instruments commands.
