2.7 Configuring the CAN2 DIP Switches
Each output channel has a corresponding DIP switch inside the CAN2-002 module. These DIP switches
labeled S1, S2, S3 and S4 are used to change the reference voltage source from either the internal 5
Volt reference (labeled Internal on the circuit board) oran external voltage reference (labeled External
on the circuit board).
For each output channel you will need to determine if the output needs to use an External or Internal
voltage reference.
This will be discussed in more detail in the gauge wiring section but for most gauges the DIP switch
should be set to external. External reference voltage uses an external voltage reference to generate the
output signal. This external voltage reference is usually the sensor power wire coming from the gauge or
from switched ignition voltage in applications that use ignition voltage as the sensor power signal.
The internal setting is used when the CAN2-002 module will supply a 5 Volt reference voltage for the
signal. This is most often used when connecting the CAN2-002 signal to some other device like a data
acquisition system, a boost or nitrous controller or some other external device.
