Chapter 6 Touch Screen LCD Operation
6.1 Touch Screen LCD Operation and Function
The Touch Screen LCD can basically do everything that a laptop computer can do. The only real difference is that there is better visibility
of a complete datalog trace on a laptop computer. The LCD allows viewing of datalogs, but due to the smaller screen size, the data must
be viewed in separate screens if the file size is very large. If the LCD is used, all functions of the controller can be programmed without a
laptop computer.
Because of this, the touch screen can be permanently mounted in a vehicle, and be used to control all functions of the Launcher. A stylus
is included that can safely be used to “touch” the screen.
The following icons appear on the main screen. Their functions are described below.
Launcher
– Provides all the functions for the Launcher Controller (described in more detail below)
Setup
– Offers the following functions:
-
Update FW - Used to update firmware. Newer LCD firmware can be loaded on the SD card and loaded via this method.
-
Files
– Allows files to be deleted from the SD card
-
Brightness
– Allows for the LCD brightness to be dimmed or brightened
Slide Show
– Allows for a generic slide show to be viewed. You can put your own images on the SD card and they can be
displayed on the LCD. Images must be a 24 bit, 320 x 240 pixel .bmp format, or they will not be recognized.
Help Menu - Offers information for technical assistance
About Menu
– Shows firmware versions for the LCD display
6.2 Launcher Functions
–
The following overviews the Launcher Functions
Configure
– Allows for all programming of the actual nitrous controller. Programs all functions for the 1-4 stages of nitrous that
can be controlled. A full overview of this follows below.
Purge
– If a stage has been configured as a purge function, this icon can be pressed to activate the purge, rather than hard-wiring
a button.
Monitor
– Shows a “gauge panel” showing engine RPM, A/F ratio, Nitrous pressure, MAP pressure, and the status of each stage.
There are four indicators showing Armed/Active/RPM/Map. When the trigger in
put is set, the “Armed” will show a green indicator.
When the system is activated, the “Active” will show a green indicator. If the high side RPM cutoff is reached, the “RPM” indicator
will turn red. If the “Map” pressure cutoff point is reached, the indicator will turn red. If any indicator is red, the unit will not
activate the nitrous. Also shown are rich/lean cutoff indicators on the monitor.
Logging
– Allows for logging of data to an SD card. This data can then be reviewed on the LCD or a computer. The user must hit
the “start” and “stop” to start and stop logging. An SD card must be inserted to capture the data to.
Controller Information (CtlrInfo)
– Shows the firmware version of the controller and other devices.
Analysis
– Allows for a datalog to be selected from an SD card and viewed. You will be asked to select a log file from the SD
card. After selecting the file, the file will be shown on the screen. About 4 seconds of data is shown at one time on the screen.
Use the forward and backward arrow buttons (double arrows) to move back and forth between screens. The
→│ and │← buttons
will take you to the beginning and end of the data. In order to not clutter the screen, all of the data (RPM, A/F ratio, trigger, etc) is
not shown all
at one time. It can be viewed separately (for the same time period) by hitting the “style” button on the bottom of the
screen. At the top of the screen, whatever data shown is indicated. Data is differentiated by color as shown.
Help Menu
– Offers information for technical assistance.
6.3 Launcher Configuring
The following takes you through the “Configure” portion with the LCD.
The first function that shows up are files on the SD card. You can select one of them and then load it to the LCD display which will
automatically download it to the controller. If you don’t want to download a file, but just modify the current program, select the “X”. If there
are no setup files which will initially be the case on a new unit, select the “X”.
The following options are the same on the LCD as they are in the PC software. These options are described in detail in section 4.2.
Please review this section to understand these options.
