How to use Labview to control Crown amplifier through network

I want to use Labview to control the amplifier through network, the amplifier is Crown I-T4000.  The Crown company provide a special software named IQwic, users can use this software to control the crown products through network. But how can I make a program by Labview, so I can use it to control the amplifier instead of the IQwic?
Firstly, I want to use ActiveX  to call IQwic in Labview, but  IQwic doesn't support ActiveX.
Secondly, I find the DLL file in IQwic software, so  "Call Library  Function Node " is used, but  I don't know how the functions in this DLL file work. Everytime the program has error report.
Lastly, there are some examples in the Crown company homepage, which use UDP/IQ network control protocol to send special UDP packet to the amplifier's IP address. But the UDP packet in these examples are so strange,  and I don't know how to  make a UDP packet in Labview.

Your advices and suggestions are expected sincerely!!!
