Frame purchase guide :

• N1 types frames and N101 types frames are NOT compatible with each other
• If you have new N101 type horn, you have to purchase new N101 type frames
• If you have previous N1 type horn, you have to purchase previous N1 type frames

Controlling environment :

• C/C++, C#, Labview, MATLAB, Visual Basic etc. : Download Library
