Welcome To ShockClock

PDA Prefs
Previous Topic  Next Topic 

> General Prefs

“Prefs” (preferences) greatly simplifies downloading and viewing records. Setup Preferences before Downloading.

 

> Select the "Prefs" button from the "Main Menu".

 

> COM Port

In order for the ShockClock to communicate with the PDA the COM Port must be selected properly.  COM 1 is the standard setting and will work for most PDA's with a serial port.

 

> Auto Erase

By default the ShockClock Software automatically erases the ShockClock following each download.  You can override this feature by un-checking the "Auto Erase" Box (this is mostly used for troubleshooting).  

 


> Vehicle Preferences (Default Vehicle for Next Download)

 

1. Vehicle List

ShockClock Software lets you define up to six different Vehicle Types.  Setting up a Vehicle Type eliminates a lot of typing.  Front and Rear settings stored in Prefs for the Vehicle Type will be automatically applied on the next ShockClock download.  

 

> Create a Vehicle Type

Place your cursor into one of the fields in the Vehicle List and type the description you want to use.  Example: 06YZ250F or 06GSXR600. 

 

2. Select Default Vehicle for Next Download

From "Prefs", tap the “Select Vehicle for Next Download” pull down menu and choose a Vehicle you have named in the Vehicle List. Tap "Setup".

 

Set Maximum Travel, Hard and Soft Bottoming Points, and Laid-Down Transducer Geometry (rear only).  Then when you download a recording from the ShockClock these settings will be automatically applied. Check the Auto Convert Box to convert the Laid-Down Data into Vertical Rear Wheel Data automatically upon download.

 

3. Maximum Available Travel

This is the most critical of all setup numbers.  It affects bottoming counts, controls graph scaling and affects the Average Travel Percentage.  Enter the maximum available travel for the front and/or rear suspension.  Check your Owners Manual for assistance.  Note that sometimes the manufacturers numbers include Top-Out Spring travel for the front end. 

 

Axle position affects the available travel as well. If the axle is mounted forward the travel will be slightly less and if it is mounted to the back the travel will be slightly more. If you want to know exactly you must disassemble the shock, remove the Bottom-out Bumper, reassemble and mount the shock then measure the travel. 

 

4. Bottoming Points Setup

How many times the suspension bottoms as well as how hard it bottoms is critical information. We have invented something called a “Soft Bottom” and a “Hard Bottom”. The idea is that Soft Bottoms can be OK but Hard Bottoms are generally not good.

 

Hard and Soft Bottoming Points are setup as a percentage of maximum available travel.  The standard settings are 90% for the Soft Bottom Point and 95% for the Hard Bottom point.  Feel free to experiment with your own settings.

 

5. Laid-Down Rear Mounting Geometry Measurements

If you are using a Laid-Down Transducer on the rear, input the geometry measurements into the appropriate fields (see Laid-Down Transducer Geometry).  Be sure to do this before riding to check for mounting geometry problems.  Check the "Auto Convert" box to automatically convert the "Laid-Down" data into "Vertical" data upon download.  If you forgot to auto-convert you can download to the PC and apply the laid-down geometry there.  See PDA Rear Laid-Down Mounting for mounting details.

 

 - Data Conversion Test

Input a Laid-Down Transducer Travel (start with a number less than the available transducer travel) and it will display the corresponding Vertical Wheel Travel.  Note that when the Transducer Travel gets too long the Wheel Travel displays "N/A".  This means that at that Transducer Travel the geometry is impossible mathematically.  By inputting different numbers it can show you how much Transducer Travel you need for the Maximum Available Wheel Travel.
