SC-1 Features 1 Introduction The SC-1 is a sail training tool designed to provide you with the feedback you need to sail faster. instruction manual is for the basic firmware version.
Device Overview 2 Device Overview Displays Speed and heading are displayed in the lower and upper displays respectively in the above figure. The information shown on each display is made clear by an indicator immediately to the left of the numerical display area. There are no indicators for the start-line display. The first decimal point on the upper display is used as an unlock indicator if any of the lock features are enabled. The indicator is not displayed if lock feature is disabled.
Device Overview 3 Buttons The SC-1 is controlled by four different capacitive touch sensors. These touch sensors detect the presence of your thumbs when they are placed on top of the regions shown in the diagram. The captions on the above diagram indicate how the different touch sensors will be referred to in the rest of this manual. Tips on Improving Button Response If you are having difficulty triggering the touch sensors, try covering the entire area of the button with your thumb.
Device Overview 4 Battery Life Indicator The battery life of 20 hrs apply for rechargeable nickel metal hydride (NiMH) batteries. Disposable alkaline batteries will provide approximately 10 hrs of battery life. Also with disposable batteries, there will be a tendency for the life indicator to remain fully illuminated for most of the battery life and only drop down to the lower levels when the batteries are nearly exhausted. The SC-1 will slowly deplete batteries even when it is turned off.
Device Overview 5 GPS Data Storage Whenever your SC-1 is turned on and has a GPS solution (i.e. when it is showing you speed, heading or distance-to-line information) it records GPS trackpoints every 2 seconds. Each trackpoint contains the following information: • Latitude • Longitude • Heading • Speed • Time The SC-1 has room for 20 hours worth of GPS data. When the SC1's memory becomes full, the oldest data on the device are automatically deleted to free up space for new ones.
Device Operation 6 Device Operation This section describes everything you need to know before hitting the water with your SC-1. Inserting Batteries Open the waterproof case and insert 3 AA batteries into the metal clips on the circuit board. Be careful to orient the batteries according to the polarity markings on the circuit board. These markings are circled in red on the photograph above. The SC-1 will work with rechargeable nickel metal hydride (NiMH) batteries or standard disposable AA batteries.
Device Operation 7 Turning Power On/Off The SC-1 Power can be turned on and off without opening the case by following the above procedure.
Device Operation 8 Signal Acquisition The operation of the Velocitek SC-1 relies on low-power radio signals from GPS satellites that orbit the earth at an altitude of approximately 20,000 km. As a result, the SC-1 must be outdoors with a clear view of the sky to function properly. When the SC-1 is first turned on, it must download information from GPS satellites before it can acquire a GPS solution.
Device Operation 9 Operation Modes There are two different operation modes, speed/heading mode and start-line mode. Details on operation in the two modes are described in this section. Speed/Heading Mode In speed/heading mode the lower display will show your speed and the upper display will show your heading. The mode will automatically switch to start-line mode if both pin and committee boat ends are set and the device is under the start-line.
Device Operation 10 Start-line Mode In start-line mode the lower display will show your distance to line and the upper display will show your heading. Mode automatically switches to speed/heading mode if the device is detected to be above the line or further than 100m from the line. Start-line ends are set by holding and releasing plus and minus buttons. Maximum speeds can be displayed by holding the Up button.
Device Operation 11 Automatic Mode Switching To limit user interaction during sailing, the mode switches automatically from speed/heading to start-line as described in the above diagram. If you do not wish to use start-line mode do not define the start-line ends.
Device Operation 12 Displayed Data Speed Speed is Doppler shift speed measured by the GPS unit. It is displayed at an update rate of 2Hz (twice a second). The speed can be displayed in knots, miles/hour, kilometers/hour or meter/second by editing the device settings. The default is to display speed in knots. Heading The heading is the Doppler shift heading measured by the GPS unit. Either true or magnetic heading can be displayed in compass mode by configuring the device settings.
Device Operation 13 Distance to line is the perpendicular distance from the SC-1 to the user defined start-line of the SC-1 in meters. The distance is calculated off of the GPS unit latitude and longitude measurements. Button Locking and Unlocking The Velocitek SC-1 uses touch sensors to accept user input. Splashing water can trigger the touch sensors.
Updating Firmware 14 Updating Firmware Firmware is the program that runs on the SC-1’s microprocessor to control how it operates. Periodically Velocitek releases new versions of firmware to add functionality to the SC-1. These updates are designed to either improve your device's performance or to tailor its functionality towards a specialized application. To perform firmware updates you must connect your SC-1 to a PC with Velocitek Software Package.
Maintenance 15 Maintenance To ensure your SC-1's enclosure remains watertight and the electronics are not destroyed by corrosion, please take the following precautions: • Store your SC-1 with the latches undone and the enclosure partially open. This leaves the gasket decompressed and allows it to expand. This ensures that it will fit tightly when the enclosure is latched and fully closed.
