#16.1 Terms, acronyms and screen names

In alphabetical order. On-screen names in bold, written as the screen writes them; guide terms in regular type.

TermWhat it is
.ftdsExported dashboard, as JSON text with the images in base64. v1: one target, written by the PC (the PC only opens v1). v2: multiple targets, written by the phone and the tablet.
2-Step / 3-StepVCU rev limiters used at the launch.
Activate night mode / EnableSwitch that turns on the night background: Activate night mode on the PC, Enable on the other devices.
Activation modeField of Device (FT700 and Plus), with Activated at 0V and Activated at 12V. It is saved, but does not change the signal: the Input sensor applies.
AlertSection of the reading gauge: mode, Low alert and High alert, in the map's unit. On the Shift, High alert is the shift point, in RPM.
Anti-lagVCU function that keeps the turbo spooled with the throttle closed.
base unitUnit in which the map and the .ftds store scale, alert and limits (km/h, °C, bar, lambda). When you change the unit, enter Minimum and Maximum again.
base64A way of writing an image as text, to fit in the map and in the .ftds. It takes up about 4/3 of the file size.
bracketDrag racing format in which each driver dials in the elapsed time they expect to run (the dial-in). The Time selector edits these times (section 6.5).
BurnoutFunction to heat the tires before the launch.
CAN / FTCAN2.0CAN (the CAN bus) is the data network between the car's modules; FTCAN2.0 is FuelTech's CAN protocol. Both are possible signal sources for an input.
Cancel changesDiscards the changes of all targets and clears the undo history. On the PC it asks for confirmation; in the touch editors, it does not.
canvasThe editor's drawing area, at the target's size.
Chroma keyVideo Overlay option that generates the video with a solid color (green, by default) in place of the image, so that another program can cut out that color.
Color / GradientColor selector: Default, Solid and Gradient (Linear, Radial, Axis), with up to 4 colors.
Conditional visibilityTurns the gauge on by a measurement (Data), in 5 modes (section 17.5). It is not Visibility, which has the Show title and Show value checkboxes.
dashboardWhat the VCU shows: up to 4 screens per target, stored in the map. The screen says dashboard.
Dashboard setupOpens the editor: 6th item of Interface Settings on the PC and 5th on the other devices (on the FT700, the Plus and the tablet the group is Interface). F3 opens it on the PC.
DashG2Internal name of the dashboard, seen on buttons in the Video Overlay Composer.
Data sourceMeasurement selector (about 1,180). When you change it, Reload data?: Yes rewrites the minimum, maximum and decimals with those of the new measurement; No keeps the old ones.
DataSourceId / GaugeTypeFields of the .ftds file: the measurement number (Number column of section 9.2) and the gauge type (0 to 32).
Day background / Night backgroundBackground of each screen, on the Screen tab. On the PC the labels are Day mode background and Night mode background.
Day/night modeVCU function: fixed day or night, dashboard button, external switch or schedule (default: night at 18:00, day at 6:00).
Deactivated / Intra / Extra / Above / BelowAlert modes: no alert; within the range; outside it; equal to or greater than the high one; equal to or less than the low one.
DeviceTab and list on the PC that choose the target. On the phone and tablet: Select target.
Divisions / DividerDivisions + 1 major marks. The divider only divides the labels: 8000 by 1000 gives 8.
Do not importDestination in the import window: the file's screen is not brought in. Screens beyond the fourth, or beyond the target's Number of screens, are not brought in, without warning.
EasingSpeed curve of the entrance animation: it says how the movement speeds up and slows down. Default OutCubic.
ECU ButtonTouch gauge that commands a VCU function, chosen in VCU Command (59 commands). The new button starts with Engine Start/Stop button: change it, because touching it commands the engine start.
Electric gaugePower gauge in both directions, traction and regeneration, for an electric vehicle (section 6.5).
Entrance animation18 effects plus None; plays once, when loading finishes.
Export dashboard to .ftds file / Import dashboard from .ftds filePC icons. Export saves the checked screens of the active target as a v1 .ftds. Import replaces the chosen destination screens entirely, which are already in the open map, without checking target or resolution, and clears the undo history.
FFmpeg / PATHFFmpeg: free video programs that Video Overlay uses to generate the MP4. PATH: list of folders in which Windows looks for programs.
Fill / Centralize / FreePositioning of the background image: stretches to the whole screen; centers; or goes to the Offset X and Y position. Scale (%), from 1 to 1000, only applies in Centralize and Free.
firmwareThe VCU's internal program. This guide covers firmware 00.03.00.54.
frameEach image of a GIF. The screen says frames.
FT700 / FT700 Plus / FT470VCU with a 7" display, with a 12.3" display and with no display. The FT470's dashboard appears on the PC, phone or tablet; in 3.00.54 the editor opens on Media Device: edit Tablet, Mobile or Desktop.
FuelTech VisionThe software on the PC, phone, tablet and the units. VisionFT is the VCU line, not the name of the software.
gaugeEach element of the dashboard. The screen says gauge.
GIFFrame-by-frame animation. It runs on its own or follows a measurement, in Position or Speed (section 17.3).
Group / UngroupGathers gauges into a Group (Ctrl+G; Ctrl+U undoes it, on the PC). Grouping resets the Entrance animation of each item. Pointers inside the Group do not rotate by value.
Hide / ShowHide or show the gauge on the dashboard in use. In the editor, a hidden one appears at 30% opacity.
hysteresisBand between two limits in which the previous state is kept: the light turns on at 100 °C and only turns off below 95 °C.
Initial screenField of Device: screen opened when the dashboard loads. It is not Startup screen selection.
Input ExpanderFuelTech input module connected over the CAN network. Its DashBtn_Switch channel delivers the same measurement as the physical screen-change button.
Input for screen swipeButton on the Device tab (FT700 and Plus) that chooses the input. The Dashboard button measurement is number 240.
InterlockCommand of the VCU's gear shift management.
IP Camera / IP camerasIP Camera is the video gauge. IP cameras is the VCU function where name, address and trigger are registered; the dashboard does not store the address. Change the equipment's factory password.
lambda / AFRMeasurements of the air-fuel mixture. Lambda 1 is the stoichiometric mixture; below 1, rich. AFR is the air/fuel ratio by mass: lambda times the fuel's stoichiometric AFR (section 9.3).
LayersList of the screen's gauges: the top is in front. Each row has an eye, a padlock, duplicate and a trash can.
LockPrevents dragging and moving the gauge. On the PC it cannot be selected by clicking in the work area: use Layers.

Media DeviceReserved target in the Device list: no screen in version 3.00.54 shows it.
MiBMebibyte, 1,048,576 bytes. The map cap, 128 MiB, is about 134 million bytes.
Minimum / MaximumStart and end of the scale, in the map's unit. When you choose the data, the app writes the measurement's default range (Tachometer with RPM: up to 32000).
Navigation ButtonTouch gauge that goes to a screen, chosen in Screen index (section 17.2).
Number of screensField of Device: from 1 to 4 screens (Video Overlay: 1).
OdometerTotal distance measurement, number 1108 (trip: 1109). Number 200 is vacant: old gauges set to it end up with no data.
Pit limitVCU function that limits speed in the pits.
Pivot X / Pivot YThe gauge's pivot, from 0 to 1 of the width and the height; default 0.5, the center.
Plot edge / Plot backgroundBorder and background of the pointer's box. They rotate with the needle and come off by default.
