Chrome Inputs - I2M Chrome Lite User Manual

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
