C-Com WP can be configured to communicate in one of two ways:

• Direct serial port connection from a PC to the ECU
• Internet connection from a remote PC to another PC connected directly to the ECU

Direct Serial Port connection

• Make sure the ECU is connected to the PC using the provided communication cable, and that the ECU is powered up.
• From the pulldown menu, select COMMUNICATION/SETUP.
   
  
  
• The communications setup window should now appear.  Under the "General" tab, select "Direct Connection" for the ECU communication method.
  
  
  
• Click on the "COM Port" Tab.  From this screen, select the appropriate COM port for your PC.  (On most laptop computers this is COM1.)  Click "OK" when finished.
  
  
  
• From the pulldown menu, select COMMUNICATION/CONNECT.
  
  (The hot key for this operation is F2.)
  There should be a progress bar at the lower right of the screen, and the word "Online" should appear at the bottom left corner when the progress bar finishes.

If the "Online" message appears, the communication setup directions may be skipped from now on.  If the "Online" message does not appear, make sure that the ECU is properly connected to the ECU and verify that the COM port is functional and properly configured.  The COM port configuration settings are located in the Windows Device Manager.

Internet Connection from a remote PC to another PC connected directly to the ECU

One of the two PCs must be directly connected to the ECU as described above.

From the PC connected to the ECU:

• Establish a connection to the Internet.  
• Start C-Com WP (if not already running) and have the serial cable connected to the ECU, but keep the software in offline mode.  Select COMMUNICATION/START SERVER from the pulldown menu.  At this point, you will be prompted to select from the available IP addresses that C-Com WP detects as available.  Select one of these IP addresses.  You should see a chat window like the one below, signifying that C-Com WP is ready to communicate with another PC over the internet. You may use this chat window to communicate with the other PC.

From the remote PC:

• Establish a connection to the Internet.  Once this connection has been established, start C-Com WP.
• From the pulldown menu, select COMMUNICATION/SETUP.
  
  
  
• Under the "General" tab, select "Network" for the ECU communication method.
• Click the "Network" tab.  On this screen, enter the IP address of the PC connected directly to the ECU.
  
  
  
• If you are able to communicate successfully over the Internet, a chat window will appear as shown above.  You may use this chat window to communicate with the other PC.
• Once the connection has been established, the remote PC will be able to view and change parameters within the ECU.
