Tech Link Software Installation

1. For a prior installation - Save away any constant files you want to keep.  Uninstall the Current
   version of Tech Link.  Use the Control Panel Add/Remove Software facility.

3. Run the setup program by double clicking on it and follow the instructions on the screen.
   NOTE: You should keep the install path the default value of "c:\Program Files\Tech Link V1.1"
   or you will have to manually copy over the applications software (e.g. TH-2, CCPM etc.)
    
4. Copy the Tech Link Icon to your desktop (from the start menu).
   
    

USB Driver Installation

1. Plug the Tech Link device (or just the FCPU-1 board) into a USB port.
    
2. A "New Hardware Found" dialog box should open.  Tell it the driver is located
   at "c:\Program Files\Tech Link V1.1\Driver" using the Browse feature.
    
3. Future updates to Tech Link will not require a new driver installation.

Error Handling and Reporting
 

• Error notification - An error condition is indicated when:
  
   

  USB connected	USB disconnected and application running
  Yellow and green LED's are ON	Yellow and green LED's are blinking alternately

  
  
  An non-error condition is indicated when:
   

  USB connected	USB disconnected and application running
  Green LED is ON only	Yellow and green LED's are OFF

  
   

• Error handling and reporting - Tech Link displays the current error status by clicking on View Error on the Tools
  menu. The error status is set upon each power up cycle only when the USB cable is disconnected.  This
  means you must apply power to the unit without having the USB cable attached to "set" the error code.  You then
  must connect the unit to the USB cable and use Tech Link to display the current error code.
