Raceclock Wireless
System Receiver

A race director is using a Time Machine to time his race and a Raceclock to display the elapsed time during the race. He would also like to display an athlete's finish time when he or she crosses the finish line. He would like the finish time to only be displayed momentarily - then to go back to displaying the Time Machine's timeclock (elapsed time) in-between finishes. The race director is also using multiple grip switches for recording different athlete categories with the Time Machine - Switch 1 for Men, Switch 2 for Women, Switch 3 for Kids, etc. But he would like to display the finish time for each competitor as they cross the finish line - regardless of category.

This requirement can easily be accomplished by programming the same wireless grip switches used for the Time Machine into the Raceclock Wireless System Receiver. For this application, the grip switches programmed into the Raceclock Receiver are assigned using "Mode 2" operations (see description above). In order to synchronize the Raceclock and Time Machine, either a "Wireless Raceclock Interface" can be used or a a single Grip Switch assigned to start "both" can be used.

This configuration will cause the Raceclock to initially display the elapsed time (Time Machine's timeclock) until one of the wireless Grip Switches are triggerred. When a competitor crosses the finish line and a grip switch is triggered, the Raceclock will momentarily "freeze" the display as it "Enters a Split". At the same time, the Time Machine will record the time in memory, transmit it to a computer and print it. After a couple of seconds, the Raceclock display goes back to showing the elapsed time - which is still synchronized to the Time Machine.

The Raceclock Wireless Interface System can greatly enhance your operation by simplifying the control of your display clocks and by adding increased capabilities to them as well.

As is depicted above, the Raceclock Wireless System Receiver can accept signals from up to four different types of wireless devices at the same time. Several Raceclocks can also be equipped with a Receiver Unit programmed to the same wireless device - giving you the ability to control any number of Raceclocks with the same wireless device simultaneously. The Receiver works with both LED and FLIP-digit type Raceclocks. For more information on the Receiver, click on the image of it above.

Since the Wireless Grip Switches and Gun-Start Transducer can also be used as inputs to the Time Machine, these devices can be used to trigger both Raceclock(s) and Time Machine(s) at the same time. This capability provides the user with ultimate flexibility in configuring their display/timing system to his or her choosing.

By incorporating the appropriate wireless devices into your operation, you can configure your display system to meet any of your specific display requirements or preferences.

Wireless Grip Switches

• Plug-and-Play replacement of the standard “wired” grip switches when used with Time Machine.
• Provides wireless connectivity up to 500 ft or more depending on obstacles.
• Rugged, sealed and waterproof Grip Switches do not require battery replacement.
• Internal battery typically lasts up to 20 years or up to 1.6 million button clicks.
• To avoid interference, each Grip Switch transmits on one-of-ten different RF Channels.
• High resolution timing correction logic delivers the same timing accuracy as wired Grip Switches.
• Can trigger any number of Time Machines or Raceclocks at the same time - both LED and Flip digit types.

Examples of Using Wireless System Devices:

• For Time Machine interface:
       • Each Grip Switch can be assigned to a specific Lane/Chute input - up to 10 can be assigned.
       • Any Grip Switch can be assigned a "Start Only" or "Start-then-Trigger Input" function.

• For Raceclock interface:
       • Each Grip Switch can be assigned to one of two Modes of Operation - up to 10 can be assigned per Raceclock.
       • Mode 1 Operation - Performs Start, Stop and Clear operations for one or more Raceclocks
       • Mode 2 Operation - Performs Start, Enter Splits, Stop, Recall Splits and Clear operations for one or more

Example 1:
Synchronizing Several Raceclocks along a Race Course





A race director is preparing to time a Half-Marathon race. He's using a popular chip timing system to get the results, but would like to give the race participants a view of their progress at various locations along the course. So he sets up a Raceclock to display the elapsed time - one located at every other mile along the course.

In the past, he had to use volunteers to go out with stopwatches and cell phones to coordinate the "setting" and "starting" of each Raceclock - in order to get them synchronized. This was very cumbersome and time consuming. And sometimes errors were made that would confuse and upset some of the race participants.

This difficult logistics problem is now easily solved with the use of a Wireless Raceclock Interface System. The race director equips each Raceclock with a "Raceclock Wireless System Receiver" and uses a Time Machine with a "Wireless Raceclock Interface" to accomplish the task.

After each Raceclock is placed along the course, its power switch is simply turned on. Then at the beginning of the race, the Time Machine is synchronized to the chip timing system (or vise versa). A Wireless Raceclock Interface is plugged into the Time Machine's External Clock Port and it is placed in the "Auto-Sync" mode. The Time Machine is then placed in a vehicle which proceeds to drive along the race course.

As the vehicle approaches each Raceclock along the course, the nearby Raceclock is automatically synchronized to the Time Machine's internal timeclock. Upon completion of the drive along the course, all of the Raceclocks are synchronized to the Time Machine and are therefore synchronized to each other - all displaying the correct elapsed time since the beginning of the race.

A high school coach is using a Time Machine to time his school's track meet and has a Raceclock available to display the race results during the meet. He would like to display the "run time" after each heat is started - and then display the finish results at the conclusion of each heat. He would then like to reset the display and repeat this operation for each successive heat throughout the entire meet.

This display operation can easily be accomplished with the use of a Wireless Raceclock Interface System and a Wireless Grip Switch System. The initial setup for this would be as follows:

• The wireless grip switches are already assigned to the Time Machine's receiver unit and labeled 1-8 (factory defaults).
• The wireless grip switch labeled "Start/1" is assigned to the Raceclock receiver unit using "Mode 1".
• The Wireless Raceclock Interface is plugged into a Finish Results Adapter, which is then plugged into the RS232 port of the
   Time Machine.

The Time Machine and Raceclock are turned on and the "1/100" key on the Raceclock keyboard is pressed in order to display hundredths of seconds. This is indicated by a "Ch:" on the display. Now the first heat is ready to begin.

At the start of the race (heat 1) the "Start/1" grip switch is pressed. This starts the timeclock for both the Time Machine and Raceclock. As soon as the first runner crosses the finish line, a grip switch is pressed to record his or her time. The Time Machine then records, prints and transmits the results. This action causes the Wireless Raceclock Interface to begin sending finish results to the Raceclock receiver. As the other competitors cross the finish line, their times are recorded by line judges pressing their respective grip switches as well.

The Raceclock now begins to display the finish results as follows:

Example 3:
Displaying "Run-Time" plus Finish Results on Raceclock During a Track Meet


At the start of the next race (heat 2) the "Start/1" grip switch is pressed again. This starts the timeclock for both the Time Machine and Raceclock - and the next race is under way.

The above steps are all repeated until the track meet has finished - and the coach is delighted that everything went so smoothly because of the ease of operation with his wireless system.

Place "1" is displayed for 2 seconds followed by the 1st place finish time - displayed for 5 seconds. After this, Place "2" is displayed - which is followed by its finish time. This sequence is repeated for the 1st thru 4th place finish results.

If the coach desired to display more finishes, he could put the Wireless Raceclock Interface into the "Extended Results Mode" by pressing and holding its control switch for 3 seconds - then release it. This will cause all finish results up to 10th place to be sequenced on the Raceclock's display.

After the finish results have been adequately displayed, the coach "presses and releases" the control switch on the Wireless Raceclock Interface. This causes the Raceclock to be reset. He also stops the Time Machine's timer and presses the SET TIME key to reset the Time Machine. The Time Machine automatically advances the heat number for the next race - which is now ready to begin.
