Chrome includes the following connections:
-
8 analog inputs
-
2 speed inputs
-
1 RPM input
-
1 water temperature input (with a dedicated warning light that turns on when the
temperature exceeds 110°C)
-
1 oil level input (with a dedicated warning light)
-
1 fuel level input (with a dedicated warning light)
-
1 battery input (with a dedicated warning light that turns on when the battery voltage drops
below 12.5V)
-
5V output for powering analog sensors that are not powered by the bike
-
12V output for powering digital sensors that are not powered by the bike
-
GPS channels
ATTENTION
:
The 5V out and 12V out power supplies can be used to power any additional sensor that is not
directly powered by the bike. DO NOT CONNECT the “5V out” or the “12V out” to any power
supply provided by the bike or to any sensor that is already powered.
ATTENTION:
Ensure that the 5V and 12V power supply does not create a short-circuit or become shorted to
ground, this could indeed damage them beyond repair leading to incorrect readings of the analog
inputs.
Analog 1-8:
these are 10-bit, 0-5 V analog inputs, to be connected to various sensors such as
throttle position, brake pressure, tire temperature, suspensions, etc...
RPM:
this input is specifically intended to record the engine RPMs, obtainable by tapping into the
signal sent by the junction box to the dashboard. Attention: the number of pulses for each engine
turn varies from bike to bike and MUST BE CONFIGURED in the dedicated menu. The system is
able to receive signals up to 20V from the RPM input.
Speed:
connect these inputs, for example, to the speed sensors on each wheel. These can be ad-
hoc inductive sensors or, for the rear wheel, the signal can be taken directly from a factory-
mounted sensor that counts the RPMs of the pinion or, in some cases, of an internal shaft directly
connected to the pinion. Warning: the number of pulses for each turn varies from bike to bike and
MUST BE CONFIGURED in the dedicated menu.
Water temperature:
0-5V input used to read the water temperature. The system has been
preconfigured for some standard sensors. 12V is the maximum voltage for this input.
Oil-level:
0-5 V input used as alarm of the oil level. The alarm level must be configured in the
dedicated “alarms management” menu. 12V is the maximum voltage for this input.
Fuel-level:
0-5 V input used as alarm of the fuel level. The alarm level must be configured in the
dedicated “alarms management” menu. 12V is the maximum voltage for this input.
