 Downloading a program to the K’NEX Interface

Use the K’NEX Computer Control Software to write your control program in the usual manner - for 

more details see the software portion of this user guide. Once the control program has been written,  

it can be downloaded into the K’NEX Interface as follows: 

 

•  Check that interface is connected & powered. If the green power indicator (next to the GO 

button) is flashing, press the GO button once so it stays lit solid green.

 

•  Ensure that a connection is established between interface and the software (the Connect/

Disconnect icon should show Disconnect). 

 

•  Ensure your control program is not being run (the Start/Stop icon should show the green 

arrow). 

To check your control program for suitability prior to download: 

  1.  Select the Download icon from the toolbar.
  2.  Click on the Test compile button.

 

3.  If the status shows as compiled OK then the program is suitable for download. 

   

Note:  When you test compile or compile and download 

your program the memory used indicator 

will show an approximation of the amount of 

memory used

To download the program:

  1.  Select the Download icon from the toolbar. 
  2.  Click on the Compile and download program 

button 

 

3.  A progress indicator will show the program being 

compiled into ‘machine code’ and downloaded.

 

4.  When the status shows as ‘Download complete’ click on Exit.

 

5.  Click on the Disconnect icon and unplug the interface from the computer.

 Running the program while disconnected from the computer

  •  Attach a power source to the interface. 
  •  Press the GO button on interface to run the program, the green LED will 

flash while the program is running. 

When the program has finished running, the green LED will return to being lit 

solid green. 
To run the program again simply press the GO button again.
To stop a program while it is still running (green LED flashing), press the GO button once. 
The interface will hold the compiled program in its memory until a new one is downloaded  

and it is overwritten.
