6 Installation
Instruction book, IQAN- XT2
CAN connection
The module has a CAN interface that can be used to connect to SAE J1939 or similar
bus for communication between IQAN-XT2 and other systems.
Connecting to CAN interface
The interface is connected from the engine’s SAE J1939 interface to the CAN2_H and
the CAN2_L.
Reference voltage, VREF
The IQAN-XT2 module is internally equipped with two voltage regulators to generate
the reference voltages VREF and VREF_EGAS. The standard reference voltage will
feed different kinds of sensors. The EGAS reference voltage is intended to supply an
electronic throttle device.
VREF positions.
NOTICE
Maximum load for the VREF and VREF_EGAS is different according to 12/24 Vdc
power supply, see Appendix A, on page 23.
EXAMPLE
Connect the SAE J1939 CAN_H and CAN_L pins to the CAN2_H, position 26 and
the CAN2_L, position 40 on the IQAN-XT2.
