Introduction
The Chrome “Lite/Plus/Pro” dash is true innovation and excellence in the field of aftermarket dashboards
for motorcycles. Combining a true color TFT display and an onboard processor, this system guarantees
total flexibility to the engineer and end user. As a result, the Chrome has been designed with a main screen
that is most suitable for its users, providing the correct spacing for each indicator. The use of a color screen
also makes it possible to immediately make visible some errors such as battery errors, fuel and oil levels
including the reserves. At the same time this technology allowed for intuitive menus with a large amount of
information. The TFT display chosen by I2M srl for the Chrome range of dashes was specifically to provide
improved visibility in direct light, treated with an anti-reflective coating it eliminates unpleasant side effects
of the sun. The Chrome “Plus/Pro” now also allow the user to select special screens and functions such as
an analogue tachometer.
In order to create the perfect combination of both display and alarm configuration, the Chrome has a total
of 12 configurable LED’s (4 configurable in RGB for the Plus/Pro Units) in order to choose the alarm
configuration that is most preferred, both linked to the RPM (the classic upper LED bar) or for example a
low tire temperature alarm were the black aluminum casing and a seven-segment gear indicator with self-
controlled brightness could complete the aesthetic side of this new dashboard.
The Chrome incorporates lap timing and data acquisition with easy to navigate menus with choosing 20
pre-determined race circuits (which can be modified with a simple import/export function). For each racing
circuit the unit can store up to 500 laps, each divided into 4 different sectors. The system can calculate and
show the user a data summary for each circuit such as; the circuit map, best lap time, the number of laps
completed and the ideal lap keeping the history for the previous sessions and those of the current day to
be able to view the progress of the current day quickly and efficiently. The unit in addition allows you to
view the circuit map directly on the display hence enabling the user to change the finish line position and
split times simply by moving the cursor along the circuit map.
The Chrome support GPS position and speed via an external 10Hz sensor, in addition it supports RPM
reading, front and/or rear wheel speed and has 8 analogue channels (10 on Plus/12 on Pro Unit’s) including
motorcycles equipped with CANBUS. The unit’s data acquisition allows the user to record up to 1GB of
data with sampling up to 100Hz per channel. A practical menu allows you to select the desired sessions,
sorted by race circuit and date. The user can delete or transfer them to a USB stick for PC analysis using
the Danas software, thus drastically reducing download times.
The system has two distinct configurations, BOX and RACE. Each configuration can be adjusted by the
user whether to display the tachometer, speed, temperature, both analog and digital channels, lap timing
and best-lap and ideal-lap time etc. Among the different options available it is also possible to display
nothing in a part/section of the display to reduce distractions whilst racing. If the system is in BOX mode, it
will automatically switch to RACE mode as soon as a set target is crossed and then return to BOX
configuration at the end of the session, this is done automatically.

Before Installation
Read the manual carefully prior starting any installation activities of the Chrome unit. A PDF copy of the
latest user manual can be downloaded from the i2m.it page.
Always install the Chrome unit inline with the installation requirements provided in this user manual.
CAUTION:
The Chrome unit is engineered and designed for race circuit use only, the unit is not approved for
street use. Certain motorcycles display their headlight and turn signal indicators on their OEM
dashboard, these functions will not be available, nor will it be accessible on the Chrome unit.
The Chrome unit is designed to utilize state of the art GPS technology to ensure lap timing and data
acquisition is accurate, therefore the GPS sensor must always have a good signal. It is recommended to
turn the ignition on at least 2-3 minutes prior to enable the Chrome unit to synchronize with the GPS
satellites. If the circuit is one of those in the Chrome circuit library, it will automatically adjust and recognize
the circuit therefore there will be no need to set this manually.
What’s Inside The Box
Once you unbox your Chrome you will find the following as a standard;
• Chrome Dashboard
• 10 Hz GPS receiver
• Standard wiring harness with GPS input connector, female USB output and sensor wiring
connector
• Electrical cable boot with clamp
• Wiring for lambda connection (with Plus and Pro only)
• Lambda O2 Sensor with connector (with Plus and Pro only)
• 2x TPMS sensors (with Pro only)
It is advisable to connect all signal cables (if there is no plug & play wiring harness for your motorcycle
make and model) by soldering and insulating connections.

Installation
Chrome “Lite/Plus/Pro”
The Chrome unit is supplied with a generic wiring harness allowing the user to connect to the supplied GPS
sensor, the motorcycle’s 12V battery and any main sensors the user may want to analyze. It is
recommended prior to starting installation that the motorcycle technician disconnect the following fuses;
• Headlight
• Brake light
• Turn signal indicators
Start with removing the OEM dash (unplug the OEM dash connector) and any fairings, covers, fuel tank (if
required) to provide enough space to route the Chrome wiring harness properly avoiding contact with the
engine case, exhaust or any areas where the harness might be damaged during operation.
Connect the supplied wiring harness to the motorcycle’s battery +/- terminals, do not remove the supplied
protection fuse at any time during the installation, nor shorten or modify any of the supplied wiring harness.
Once the battery is connected and the supplied wiring harness has been routed (cable tied), connect the
Chrome unit. Ensure that the female USB connector is stored in a dry place (this can be under the rider
seat or in the front fairing). Supplied is an electrical rubber boot, ensure once the installation is complete
that all the cables pass through the boot to the rear connectors of the Chrome unit, secure the boot with
the supplied strap and tape the wiring to the boot limiting water and moisture ingress.
Now connect the GPS sensor to the wiring loom supplied. Route the GPS sensor to the rear of the
motorcycle (the subframe). Depending on the motorcycle make and model there might be a need to drill a
small hole in the top part of the tail fairing to properly route and mount the GPS sensor. Secure the GPS
sensor to the top most rear part (this is to allow for better/uninterrupted GPS signal) of the tail fairing with
3M extra strong double-sided tape or equivalent (avoid any metal parts near the GPS sensor).
Note: USB flash drives must have only one partition, be formatted in either FAT32 or exFAT else the
Chrome unit will be unable to connect with the flash drive. For more information on deleting/creating
partitions and formatting drives please visit:
https://www.qualityology.com/tech/properly-delete-a-partition-on-usb-drive-using-diskpart/
https://www.techwalla.com/articles/how-to-format-a-flash-drive-to-fat32
Motorcycle Specific Wiring Harness, CNC Adaptor Plate (P&P Kits)
Depending on the purchase, the Chrome supplied may have included accessories like a CNC adaptor
plate/dash mounting bracket and OEM to I2M P&P wiring harness.
If the P&P CNC adaptor plate is included in the purchase, install the adaptor plate utilizing the OEM dash
mounts on the front fairing stay. The adaptors orientation needs to be verified to insure the dash is able to
mount correctly (upright). Once the adaptor plate is connected and fastened, mount the Chrome unit to the
adaptor plate using the supplied fasteners, grommets, washers etc.
CAUTION:
The Chrome unit must not be fixed to elements subject to vibration such as fairings and frames. The
Chrome unit is equipped with anti-vibration rubber dampers therefore it is advisable to use existing
OEM anchoring dash mounts to reduce vibration to the absolute minimum. Do not remove the rubber
dampers and ensure the Chrome unit is not in contact with any part of the motorcycle other than the
rubber dampers at any given time. If the Chrome unit is incorrectly mounted to the motorcycle and
subject to vibration it can damage the unit thus leading to malfunctions etc.

www.i2m.it/en
9
If the P&P OEM to I2M wiring harness is included in the purchase, the generic installation method would
be to connect the one end to the supplied I2M wiring harness and the other to the original OEM dash
connector and if necessary, to the CANBUS connector (the 2-pole connector supplied to the 20-way
connector on the rear of the Chrome unit).
CAUTION:
For motorcycles equipped with a BUS, failure to connect this 20-Pin connector will impact the functionality
of the Chrome unit as some channels might be lost (not read).
Sensor Connector Wiring Harness (P&P Kit)
Depending on the purchase, the Chrome supplied may have included accessories like a sensor
connector wiring harness and some associated sensors i.e. potentiometers, inductive speed sensor,
brake pressure sensor, infrared temperature sensor etc.
If the P&P sensor connector wiring harness is included in the purchase, the installation method would be
to connect the harness to the Chrome unit (20-Pin BUS connection) however, it is possible to connect the
sensors manually using the pinout provided in this manual. Any additional sensors need to be installed
individually and always ensure that all wiring is correctly routed.
Note: Potentiometers are not supplied with fork/frame/mounting brackets, the same applies to speed and
temperature sensors.
Once the various sensors (channels) are connect to the Chrome, turn on the ignition and access the
Chrome “Configure Inputs” menu. Once accessed the channels can be viewed in real time with the first
screen showing 8x analogue inputs, speed and RPM. Holding the “DN” button for 5 seconds will switch the
screen showing the battery, water, oil, fuel and additional channels EXT1, EXT2 (with Plus only), EXT3 and
EXT4 (with Pro only). The water temperature sensor value may need individual configuration.
Should the installation be done using the generic supplied wiring, keep in mind that signals form the OEM
sensors may need a pull-up resistor to 12V or a pull-down in order for the Chrome unit to read the channel
correctly. Neutral and Oil is most common for requiring a pull-up resistor (2kOhm in most cases should be
enough).

www.i2m.it/en
10
Chrome Inputs
The rear of the Chrome unit is equipped with 2x Multilock female connectors, one with 16 and the other
with 20 pins. In addition to this there is two screwed connectors, one for video input (with Plus and Pro only)
and the other for the TPMS antenna (with Pro only).
The Chrome unit is equipped with a dual power supply, one directly from the motorcycle’s battery and
another from the OEM wiring loom. The unit does not draw current when turned off from either one of the
two power supplies. The direct power supply’s main function is to ensure the unit always closed files
correctly during the shutdown phase. To avoid any startup delays at the racing circuit the unit can operate
in a suspended mode (sleep mode), this can be activated in the options menu. If this function is active, the
unit can still be shut down by holding the “DN” button until the LED is lit above the gear indicator.
The Chrome unit is designed to be versatile and can function without connecting all inputs i.e. GPS
sensor etc. The unit comes equipped with the following inputs;
• 8x analog Inputs
• 2x EXT inputs (with Plus, and 4x on Pro)
• 2x speed inputs
• 1x RPM input
• 1x water temperature input (with onscreen fault indicator)
• 1x oil level input (with onscreen fault indicator)
• 1x fuel level input (with onscreen fault indicator)
• 1x battery input (with dedicated fault indicator, lit below 12.5V)
• 10x channels multiplexed at 1/10 of the sampling frequency
• 5V output for additional analog sensors
• 12V output for additional digital sensors
• GPS channel
• Video input (with Plus & Pro only)
• TPMS input (with Pro only)
CAUTION:
The 5V and 12V outputs can only be used to power any additional sensors that is not directly powered
by the motorcycle. Do not connect the 5V or 12V outputs to any power supplies or sensors directly
powered by the motorcycle. This could create a short-circuit or short to the ground, thus damaging the
outputs beyond repair.
8x Analog Inputs - (0-5V to 10 bit) are mainly used to monitor throttle position, brake pressure,
potentiometers and temperature sensors etc.
2x EXT Inputs – These channels are connected directly to the Analog 1 and Analog 2 inputs. Motorcycles
with CANBUS (see table), channel 1 and 8 are utilized for the TPS and TC directly from CANBUS. With
EXT1 and EXT2 it is therefore possible to connect these inputs if external to the motorcycle. If the
motorcycle does not support CANBUS, these channels will simply mirror Analog 1 and Analog 8 inputs.
CAUTION:
When the OEM dash is removed, some pull-up resistors may be removed too. These resistors play an
integral part to reding sensors correctly i.e. oil or fuel levels. If a OEM to I2M P&P harness is not used,
check the signals as there might be a need to add some pull-up resistors.
2x Speed Inputs – These inputs can be connected to the OEM and inductive speed sensors for both the
front and rear wheel. The number of pulses vary from motorcycle to motorcycle and therefore has to be
configured in the Chrome unit’s menu.
1x RPM Input – This is a dedicated input for the motorcycles engine RPM and obtainable by accessing the
signal sent by the junction box to the OEM dashboard. The number of pulses vary from motorcycle to

www.i2m.it/en
11
motorcycle and therefore has to be configured in the Chrome unit’s menu. The unit is able to receive signals
up to 20V only.
1 x Water Temperature Input – (0-5V) input is used for water temperature. The unit has been
preconfigured for some sensors and 12V is the maximum voltage for this input.
1x Oil Level Input – (0-5V) input is used as an alarm if the oil level is too low. The alarm level must be
configured in the alarm’s management menu and 12V is the maximum voltage for this input.
1x Fuel Level Input – (0-5V) input is used as an alarm if the fuel level is too low. The alarm level must be
configured in the alarm’s management menu and 12V is the maximum voltage for this input.

on the right side of the unit. These buttons can also be operated remotely from a button pod/switchgear on
the handlebar of the motorcycle if connected to the supplied wiring loom connector. The “UP” button allow
navigation to upper entries, the “DN” button to lower entries. If the “UP” button is pressed in the startup
screen the “View Lap Times” menu will appear and if the “DN” button is pressed the main menu will appear.
To enter a specific menu item (one level down), hold the “DN” button (referred to as “LDN”) for 1-2 seconds
to enter the menu item or to modify a parameter. To exit the specific menu (one level up), hold the “UP”
(referred to as “LUP”) button for 1-2 seconds to exit the menu item or the modified parameter. To change
the button configuration, navigate from the main menu to “Options”/ ”Display”.
Editing Alphanumerical Values
As shown above, the Chrome unit makes provision to edit parameter, values and names for inputs or race
circuits. Changes can be made to each individual character using the “UP” and “DN” buttons, use “LDN” to
change from one character to another and the “LUP” to exit the selected item.
Startup Screen
When the Chrome unit is powered up, it will depict a similar main screen as shown above. The top left part
of the screen will indicate GPS connectivity. Once the GPS is connected a connection bar will appear
showing GPS signal strength, if this bar fails to appear check the connection and ensure the sensor is
connected to the unit (he GPS icon will appear red in color if the GPS is connected and awaiting signal
positioning).
When the unit is recording data/video a small icon “REC” will appear directly under the GPS icon. Similarly,
if the WiFi is connected and the heart rate monitor a small icon will appear below the “REC” for “WiFi” and
a red heart below that (WiFi with Plus and Pro, heartrate with Pro only).The main screen layout is completely
configurable, please refer to “Display Configuration”.

OEM to I2M P&P Wiring Harness
Connecting the P&P wiring harness is the best and easiest way to connect the Chrome unit to the
motorcycle. Simply connect the P&P wiring harness between the 12-Pin connector and the OEM dashboard
connector then load the appropriate motorcycle make and model and you are done.
Some motorcycles may have additional connections depending on make and model, cases like these are
listed below;
• Yamaha – the P&P wiring harness includes a male/female connector to be connected in series
with the OEM speed and water temperature (blue cable) sensors. Both have two cables, one of
which is connected to the motorcycles ground (black wire). It is advisable to use a multimeter (or
similar apparatus) to verify which OEM cable is in fact ground prior to termination.
• Suzuki <2017 & Kawasaki 400 – the P&P wiring harness includes a a blue cable to be connected
to the water temperature sensor. It is advisable to use a multimeter (or similar apparatus) to verify
which OEM cable is in fact ground prior to termination.
• Motorcycles with CANBUS – the P&P wiring harness may include a CANBUS connection, the
CAN connector (2-pole AMP) must be connected to the corresponding CANBUS connector on the
Chrome unit (20-Pin connector).
Loading Motorcycle Specific Settings
Once the installation is complete, navigate from the main menu to “Options”/ ”Kind of Bike” and select the
appropriate make and model motorcycle from the list. If the motorcycle, make and model is not present
proceed to select only the related make i.e. “Yamaha” as most of the parameters is preconfigured, if the
case and a BUS connection is present leave the pinion and crown teeth at 1-1.
Acquired Channels
Depending on the motorcycle make and model the Chrome unit might be preconfigured to load preset
channels. Please refer to the channel list for more information.
Unit Configuration
Once the installation of the Chrome unit is complete and all connections have been terminated the user
can personalize the unit by configuring the settings i.e. BOX, RACE, inputs, alarms etc. For configuration
refer to input configuration and as a first step rename/update each channel with the desired name, minimum
and maximum values and selecting manual or automatic modes.
All LED’s are configurable via the “Alarms” menu, the user can configure each LED (including fuel, oil, water
and battery). To configure the RPM LED’s simply select “RPM Mode” and the unit will automatically
configure the 7x white LED’s to illuminate through the selected RPM range. It is recommended to;
• Configure the RPM range for the LED alarm
• Navigate to the “Alarms” menu and deactivate, then reactivate the RPM mode (this configuration
requires the unit to be restarted)
• Return to the display menu once complete and select the RPM range i.e. for a V-Twin with lower
revolutions it is best to set the maximum to 12,000RPM (the same as the OEM dashboard).
The RPM limiter function can be accessed via the “Overrun Flashing” menu, by activating this function the
LED’s will start flashing once the set RPM limit is exceeded.
Gear Indicator
To configure the gear indicator on your Chrome unit (motorcycles not equipped with a BUS and/or no BUS
signal for gear selection) follow this simple procedure;
• Ensure the speed and RPM inputs have been configured

www.i2m.it/en
15
• Go to the “Data Acquisition” menu, change the following parameters; Recording: ACTIVE,
Sampling Frequency: 100Hz, Lower Speed: 20km/h, Autostart Channel: SPD1
• Now start the motorbike, change gears from N,1,2,3,4,5,6 maintaining 20sec intervals (ensure that
the REC icon is active on the startup screen)
• Upon completion, kill the ignition and select the “Inputs & Special Functions/Configure
Inputs/Configure gears (no CAN)”
• Once done you can configure the gear acquisition again if required
The Chrome unit calculates gear indication referring to sessions of the day, therefore the procedure can
simply be performed utilizing a dyno tune facility or a race circuit. Ensure that all the gears are properly
engaged and that the data calculation is done on the same day and location.
Adding a New Circuit
There are two options available for adding new circuits to the Chrome unit;
1) Update the Danas circuit library
2) Modify existing circuit on the Chrome unit
Update the Danas circuit library
To update the current Danas circuit library, open Danas on your personal computer and navigate to
“Online/Configure Chrome Circuits”. The list will have all the circuits available, add new circuits with the “+”
icon (always ensure that the complete list has a minimum & maximum of 20x circuits).
Once all circuits have been selected move the “CircuitInOut.ccr” file to a USB flash drive (FAT32/exFAT
formatting with 1 partition only). Now connect the USB flash drive to the Chrome unit and import the
circuits via the “Chronometer/Export & Import/Import Cicuits from USB” menu.
CAUTION:
The circuits must be exactly 20x in total, do not import less than or greater than 20x circuits as this will
cause the unit to malfunction.
Modify existing circuit on the Chrome unit
• In the Chrome units menu select “Chronometer/Select Circuit” to open the circuit list, proceed to
select the required circuit or select a circuit that is FREE/can be replaced.
• Proceed to navigate to “Chronometer/Circuit Details/Update Name” to change the circuit name and
to manually select the finish line position, change “Update Finish Line Position” to “UPDATE”,
ensure the units position is on the finish line prior to confirmation. Alternatively, select the “AUTO”
function for automatic configuration.
• When the “AUTO” function is selected, the system will automatically set the finish line position when
the motorcycle exceeds a 150km/h thus starting the lap timer at that point.
• Once the session is finished, the user can move the finish line and/or split positions on the “MAP”
in the “Update Finish Line Position” selection.
Exit Standby Mode and Shutdown
If the standby time has been configured the Chrome unit will turn off the display and some peripherals (not
the GPS) in order to reduce power consumption. The unit will automatically shut down after the set standby
time has lapsed. If the user would like to turn off the unit prior, follow the below instructions;
• Turn off the Chrome unit
• Wait until the LED in the bottom right corner flashes
• Press the DN button until the red LED above the gear indicator illuminates
• Release the DN button
• After 2-3 seconds the upper white LED will flash, this indicates that the Chrome has successfully
shut down

Software & Firmware Updates
Prior to updating any software and/or firmware on the Chrome unit, verify if it is required;
Go to the menu “Options” and verify if the currently installed version is older than the latest version available
on the I2M website (https://i2m.it/en/download-list/);
Software Update “Quick Links”
• Chrome “Lite/Plus” - http://www.i2m.it/download/softwarePlusLite.zip
• Chrome “Pro” - http://www.i2m.it/download/softwarePro.zip
Firmware Update “Quick Links”
• Chrome “Lite/Plus” - http://www.i2m.it/download/firmwarePlusLite.zip
• Chrome “Pro” - http://www.i2m.it/download/firmwarePro.zip
If an update is necessary, please proceed as follow;
• Connect a USB flash drive to a personal computer (FAT32/exFAT formatting with 1x partition
only)
• Download the required firmware and/or software version from the I2M download portal
• Extract the ZIP files to the USB flash drive (do not extract both the firmware and software files at
the same time to the USB flash drive, this will need to be done individually i.e. first copy the
firmware file [*.hex], then delete this file from the USB flash drive and copy the extracted software
files to the USB flash drive)
• Connect the USB flash drive to the Chrome unit
• Proceed to the “Options” menu and select “Update Software/Firmware from USB”
• Once selected the update will commence (Firmware updates take 3-5min to complete where
software updates are instant)
CAUTION:
Do not turn off the motorcycle’s ignition (remove power from the unit) at any point in time whilst the
update is in progress, this could cause the unit to malfunction.
• Set the “Standby Time After Shut Down” to 0 hours (if otherwise set) in the “Options” menu
• Shut down the Chrome unit completely
• Restart the unit, then navigate to the “Options” menu to verify if the update was successful (the
firmware and software versions should reflect the update versions)

Chrome Menu
Startup Screen
In the startup screen, press the DN button to open the Chrome unit’s main menu. This menu includes the
main system functions i.e. Chronometer, Display View, Data Acquisition, Video & WiFi, Counters, Inputs &
Special Functions, Alarms and Options. To select a menu item press LDN or to return to the startup screen
press LUP.
Note: This user manual has been developed for the Chome “Lite/Plus/Pro” hence some functions described
below might not be available depending on the purchase made.
The main menu consists of the following;
• Chronometer à
• Display View à
• Data Acquisition, Video & WiFi à
• Counters à
• Inputs & Special Functions à
• Alarms à
• Options à
Each of the above items have their individual sub-menu (sub-directory) tree, these have been mapped
individually for quick reference below to avoid the user having to browse through directories on the Chrome
unit thus familiarizing themselves with the Chrome interface.

Chronometer
(Chronometer sub-menu tree)
The Chrome unit includes a GPS chronometer with a resolution of 1/100s, based on a 10Hz MTK GPS
processor with 66x parallel channels. During startup, once the GPS signal is calibrated, the system
identifies where it is located among the 20x stored circuits then proceeds in identifying coordinates for the
finish line of the identified race circuit. If the coordinates don't match with any of the stored circuits, the
message "Circuit Not Found" will appear on the startup screen.
CAUTION:
The circuit identification is only performed during the startup (boot). If the unit is turned
on before reaching the race circuit, the user has to restart, or manually set the desired circuit.
Thanks to the "Chronometer" menu it is possible to display the lap times, erase them and configure
all the chronometer options. As for the other menus, press the LDN to enter the submenu, or press the
LUP to return to the previous menu.
View Lap Times
It is possible to display the stored lap times from the “Chronometer” menu by pressing the LDN button or
the UP button from the startup screen. The lap times performed in the selected circuit are shown in this
menu (if no circuit is selected a blank screen appears). Lap times are automatically divided by sessions
and each session lists the date and the starting time of the session itself. The displayed lap times are
divided into three columns, corresponding to the three split sectors of each lap, and for each lap the best
speed is reported. The all-time best lap and ideal time for the current circuit are shown in the lower part of
the screen.
ATTENTION: If the position of the split times on the map is changed, the previously stored laptimes still
remain referred to the old position.
ATTENTION: The best and ideal lap displayed in the lower part of the screen refers to the selected circuit
and not only to the shown times. As will be discussed in the section that describes the

cancellation, it is possible to delete lap times leaving the best and ideal lap stored, or vice versa. In both
cases, it would be reasonable to have no more correspondence between the all-time best lap
and the best lap in the list.
Delete Lap Times
The “Delete” menu allows to select which information has to be deleted. Indeed, it is possible to delete only
the best time relative to the selected circuit, or the list of times, the ideal time or all the times stored in the
memory. Keep the DN button pressed to select an option, then follow the instructions on the screen to
confirm the cancellation.
Select Circuit
The “Circuits” menu shows the list of the circuits stored inside Chrome. Chrome is able to store up to 20
different circuits. For each one the best lap, the number of stored laps and the higher speed are collected
in a table. Thanks to the automatic identification of the circuit, Chrome recognizes the circuit where it is
located. Using this menu, it is also possible to choose a different circuit. Press the UP and DN buttons to
scroll through the circuits, keep the DN button pressed to select the circuit, keep the UP button pressed to
return to the previous menu.
Circuit Details
In the “Circuit detail” menu the information about the loaded circuit is reported. In this menu the number of
stored laps, best and ideal lap times and highest speed are shown. The maps, which are automatically
generated by the system, are displayed on the left part of the screen. If there is no corresponding map
stored in the memory, Chrome starts to draw the map the first time the finish line is crossed and it stops
when the finish line is crossed again. If the lap is not completed, the map will not be saved. It is possible to
remove the auto generated maps selecting the “remove map” function.
The configurable parameters for the circuit are shown in the lower part of the screen. The name of the
circuit can be changed using the first line: this option makes possible to modify each letter of the name.
Keep the DN button pressed to switch character, press the UP and DN buttons to scroll through the letters
and keep the UP button pressed to exit. The finish line and splits can be set by using the three subsequent
entries. It is possible to select one of these options to manually set the finish line (in this case the finish line
has to be crossed without stopping) or, if the map is available, to set the finish line or the splits by choosing
the desired position on the map. Indeed, it is possible to move the cursor, through the map, using the UP
and DN buttons until the desired position. The “Auto” option automatically sets the finish line when the 150
Km/h speed is exceeded. The first split can be set only if the finish line was stored. Similarly, the second
split can be set only if the first split was stored.
WARNING: do not use space or special characters in circuit names
Daily Details
The “Daily details” menu summarizes the current day performance. Therefore, it is possible to analyze the
number of performed laps, the highest speed, the best and ideal laps and the spread between the latter
and the all-time best and ideal laps.
Export & Import
Thanks to this menu it is possible to manage the downloading/uploading of data collected during the
chronometer functions. It is possible to download the stored circuits by using a USB flash drive in order to
save the new finish line in a file compatible with Danas. Similarly, it is possible to load a circuit list by using
a USB flash drive, replacing the circuits stored in Chrome. The file must be generated by selecting the
proper option in the Danas software and then transferred using a USB flash drive. Choosing “export lap
times to USB”, a .txt file, including the total and split lap times and the highest speeds, all organized in
sessions, is generated.

Circuit Library
Through the “Circuits library” menu each of the 20 circuits stored in memory can be changed. Simply choose
the circuit to change in the first row. The new circuit voice allows to choose which circuit shall replace the
current one. The circuit will be chosen among those in the library. The latter can be extended by simply
importing it from a USB key. It is possible to download directly the update file from the download area of
the www.i2m.it/en website.
