Watch-Dog -Inline- Timing

System FAQs

Updated 12/06/2007



  • What is the Watch-Dog -InLine/Speed Skate timing system?

  • The Watch-Dog -Inline- timing is a special set of timing sensors and display control console designed track laps and lap times of sports like inline or ice speed skating.

  • How long does it take to get a system?

  • Typically I give my self 2 weeks to build a system from time of order. How ever I expect to have at least 1 -Inline- system built ahead so the wait time may be shorter for some order..

    I do have a couple of systems that could go out in time for X-mass....

  • What Functions may be controlled by remote?

  • One Keyfob type remote control comes standard with each -Inline- Systems.
    From the remote you can Reset the lap count to Zero (Lap Count Reset), Reset the timer to zero (Lap Time Reset), Trigger the race total to be displayed (End Race Total), and Reset the sensor delay (Delay Reset).

  • Can the console be operated by more then 1 remote?

  • Yes.. The console can be operated by more then 1 remote and may be configured to receive signals from up to 15 remotes. This allows more then 1 ref to carry a remote control if desired. Additional remotes may be purchased separately.

  • What is the remote controls range?

  • The remote will operate up to 100ft or more. Building design and console location (floor vs table) can play a roll in the max distance but typical range is over 100 ft.

  • Can the system be run off battery power?

  • The start finish beam requires only a 9v battery for power. An AC/DC adapter is provided standard for powering the system console. How ever the system is designed to run off any 12vDC source. So for example you could run the system with a small car battery. The console uses a standard 5.5mm round power connector with a 1.2mm center pin. Polarity is Center Positive. So you may wire your own connector. Connectors for doing this are available at any RadioShack store. I could also make up an adapter if Requested

  • How are the times displayed?

  • While running lap times are displayed as the lead skater triggers the start/finish beams. For each lap the lap time is displayed in SS.ss format
    S = Second
    s = Sub Second
    Following the end of the race the operator would press the "End Race" button on the console or remote. This will cause the display console to show the race total. Race totals are displayed in MM.SS and S.sss formats. The console will change between showing the 2 times every 3 seconds. So for 3 seconds it will show MM.SS on the display then change to display the reset of the time S.sss This will continue until the console is reset for the next event.

  • Explain the Lap Counter functions?

  • The operator may configure the system to count laps Up or Down, May add or deduct laps from the lap display using the Count Up and Count Down buttons. These would be used to adjust the laps setting the system up before the start of an event

  • Can the emitter enclosure be mounted to a wall?

  • Yes, if needed a 90 deg angle adapter is available (separately) for using the system at locations where the speed skating surface has a wall directly adjacent to the floor. The emitter enclosure can be attached to the wall with tape or other simple fastening method and is only a little over 1" thick when placed vertically on a wall.

  • How wide can the start/finish line be (distance between the beam sensor enclosures)?

  • The system sensors are very high quality long distance through beams. They my be placed up to 20m (65ft) appart. They are typically not effected by sun light and may be used in or outdoors.

  • How does the system automatically count and display lap times?

  • The system has a built in adjustable sensor delay cycle. Setting the delay to a few tenths less your fastest expected lap the system will accurately & automatically track lap times and track lap counts.

  • Can the beams be manually disabled for longer duration events such as 3K sprints where other people (bikes/runners ect) may be using the are between the skater leaving the start and returning?

  • Yes, there is a manual disable/enable button on the console. This may be pressed at any time. But in this example the operator would press this button manually disabling the beams during the delay period following the first triggering of the beams. The operator would press the disable/enable button again just before the skater returns to trip the beams once again. Once tripped the operator would press the End Race/Total button to display the skaters total time.

  • How do you set the delay cycle?

  • The console is equipped with a Delay Test button on the back of the console. The operator would select a delay amount on the delay dial. Reset the system, press and hold the Delay Test button until the timer stops running. The seconds displayed will be the current delay setting. If a longer or shorter delay is desired the operator would rotate the delay dial and repeat the process. Typically the delay would be set to a few tenths of a second faster then the fastest expected lap.

  • Can the delay cycle be manually Canceled/Reset?

  • Yes The operator may cancel the delay cycle by pressing the Delay Reset button on the console. This will cause the system clock to be triggered by the very next object which blocks the beams after pressing the button.

  • Can larger external displays be added?

  • The Standard Universal large displays have 2.5" tall LED numbers. This is an optimal size to keep costs as low as possible. The 2.5" LEDs are very bright making them as easy as possible to read from a distance. Larger displays are available how ever as size increases cost also go up, portability goes down ect.

  • We have been considering buying a system, but would like to see the system in action. Can we get a demonstration of the system?

  • I'm located in Michigan and plan on attending many events this year and could bring a system with me to show.
