1. Install Batteries in the ShockClock

Remove the back cover of the ShockClock and Install 3 AA Batteries. 

 

Note that the foam mounted on the inside of the back cover should press against the batteries when the cover is reinstalled.  This keeps the batteries from moving under harsh conditions.

 

2. Connect the Transducer to the ShockClock

The transducer should always be connected to the ShockClock when operating to protect the ShockClock circuitry.

 

3. Turn the ShockClock On

To turn on the ShockClock press and hold the “Power” button.  The “Power” and “Temp Calib” lights will go on immediately.  After about 3 seconds the “Record” light will go on.  When this happens release the “Power” button.  The “Record” light will then go out.  You are now ready to record.

 

4. Begin Recording

Press the Record button (or use the Remote Record Switch supplied in the Pro kit).  The Record light will flash a few times and light up.  If you listen closely, you may be able to hear the transducer making a buzzing sound.

 

5. Pump the Transducer Tubes

Pump the tubes in and out for about ten seconds.  Then stop recording by pressing the Record button one more time.

 

6. Connect the Download Cable

Connect the Download Cable from your Computer to the ShockClock.  Make sure the connections are clean.  Use a USB/Serial Adapter if necessary (be sure to install the adapter software driver as well).

 

7. Launch ShockClock Software and Set the COM Port

If you are using a 9-pin Serial Port you probably will use the default setting of COM 1 and it will work perfectly without changing a thing. 

 

If you are using a USB/Serial Adapter you will need to set this up.  Go to Edit, Preferences (Ignore the Vehicle Type for now).

 

Set the COM Port to the correct number.  To find the correct COM port number see 2.4 Determine the COM Port Number.

 

8. Download the File

After setting the COM Port number select File, Download (or use the shortcut Ctrl+D) to start the download.

 

At this point it will check to see that it is communicating properly with the ShockClock. If it isnt, an error message will appear.  If this happens refer to 4.3 ShockClock Problems.

 

If communication between the ShockClock and the computer are working properly, the next screen you will see is Set Air Temperature.  The Air Temperature screen is explained in detail in 5.3 Downloading.  For now, press the OK button to proceed.

 

9. Create a Filename

After the Download Progress Bar completes, you will come to the Create a Filename screen. Create a Filename creates a meaningful filename for your recording while automatically storing the values you choose into the Notes, Clicker Settings Screen.  This is explained further in 5.12 Notes.  

 

For now press the OK button to enter the File Save Screen.  Save the file to any location you want.  

 

We suggest you create a new directory in "My Documents" called "ShockClock Data".  Then make sub-directories with the bike model names to keep your records in.  Example: My Documents\ShockClock Data\06 Honda CR450F

 

> Thats it.  If everything worked correctly your downloaded file was saved to your hard drive and the new file opened up automatically.  You should see a screen similar to the one below.  Feel free to explore the software at this time.
