VIEW LIVE RESULTS!

Register and be able to view live timing! You may also view previous results for analysis.

Each timing system has a unique serial ID and password which is required when creating an online account. Thereby only accepted persons are able to view live timing from your timing system.

SUBSCRIPTION

View accounts are free. This type of account is meant for people associated with the athtletes. You define your account type when registering.

An athlete account has a subscription fee of 49,- NOK (Norwegian krone) monthly. A unique athtlete ID will be generated and is entered by the skier at start of the slalom course.

An athlete account also have access to view both live timing and previous results.

Technical Specifications
Weight400 grams
DimensionsEnclosure: 210 x 100 x 38 mm^3; Antenna length: 180 mm
Radio physical layerIn mesh network mode: Frequency Hopping Spread Spectrum (FHSS), GFSK modulation, narrowband channels with high sensitivity receiver, 17 channels (FHSS) @ 869 MHz ISM band, 25 mW ERP, radio collision avoidance (Listen Before Talk).
Radio protocol layer Full mesh network. Supports up to 6 jumps in any possible jump path (example: Start ⇒ IM1 ⇒ IM2 ⇒ IM3 ⇒ IM4 ⇒ Finish ⇒ wiTimer).

Radio packet validness check (CRC-16). Handles reception of simultanous impulses from up to 6 wiNodes.
Radio transmission range wiTimer to wiNode: * 1.5 km to 14 km. wiNode to wiTimer 14 km (see wiNode specs.). Typically, wiNode modules are positioned at the top of every pitch throughout the slope. This ensures that the wiTimer is always within reach of at least one wiNode - which is sufficient.

(1.5 km is a conservative result based on the '2-Ray ground reflection model' where modules are placed 2 m above ground level. A more than adequate fade margin of 14dB is used in the model. 14 km is based on the FRIIS model where each module is placed very high above ground level [like mountain top to mountain top]).
Intermediate/Split restrictionsNone. Unique arrival window for each split intermediate. Next athlete can enter his/her BIB# and start immediately, even before other skiers on course have passed intermediates.
Unique IDFactory set unique ID for each timing set. Prevents interference impulses from all other timing systems.
Impulse acknowledgment wiNodes continuously evaluate neighbour wiNodes (direct wireless contact) and expect them to re-transmit (relay) impulses (MESH). If this fails to happen, a new radio channel is selected and the same impulse is transmitted again. This happens until all neighbour wiNodes have relayed the impulse.
Reflector status Realtime photocell reflector status on wiTimer display. If any reflector falls out of focus with the photocell, a corresponding warning icon on the wiTimer display is lit. Poor, though functional, focus is also indicated for early warning.
Impulse controlManual impulse manipulation when stray skiers pass photocells while arrival window (pace) is open.
Impulse accuracywiNode to wiNode/wiTimer: ± 0.2 ms
Time base26 MHz TCXO (Temperature Compensated Crystal Oscillator), ± 1 ppm stability vs. temperature, ± 2 ppm initial tolerance, ± 1 ppm/year aging
Operating temperature-20 C° to +50 C°
Power supplyInternal 2500 mAh Li-po battery with intelligent internal charging circuit. Battery temperature monitor, short circuit protection and overvoltage protection. Rechargable. Also rechargable by USB Power bank.
Battery life12 to 20 hours of continuous use. Battery level indication shown on TFT display. Battery levels for all wiNodes also shown on wiTimer display.
Microcontroller32 Bit. 1024 kByte FLASH. RTOS.
User interface Waterproof 10-button keypad. Sunlight readable 320x240 pixels TFT display. Easy user interface. The 3 most recent full time resuls with up to 4 intermediates shown on display with +/- time comparisons (individual and all vs. all). A fourth column for scrolling through all results, with BIB#-Lock for quick access. All time results are selectable with arrow buttons for various manipulations, including: Change BIB#, Select correct impulse (stray skier), Manual DNF, Set IM1/2/3/4 and finish to DSQ (disqualify), False start and False event.
Memory16 sessions, each with up to 511 results including up to 4 intermediates per session. A total of 49 056 results + 104 848 impulse events. Memory retention after power down. SDRAM and FLASH.
Cable connectionsOutput impulse connector available on request.
Water protectionIP65

Tips


Did you know that all the wireless nodes (intermediates, start and finish), also act as wireless repeaters?


Did you know that you can place all your intermediate nodes in the slalom course in order to benefit from the wireless repeater feature (mesh technology), even though you only plan to solely use start and finish?


Did you know that you don't define a common radio frequency channel for the timer and the nodes? The system uses frequency hopping spread spectrum (FHSS) which means that the timer and the nodes are changing radio channels many times every second. This is very beneficial when channels are bussy or experience interference!
