30-2207 GPS Module
AEMnet (CAN Bus) Output
WHITE WIRE WITH BLACK STRIPE = / CANH
GREEN WIRE WITH BLACK STRIPE = AEMnet- / CANL
The AEMnet output is suitable for output to AEM devices such as the CD Dash, AQ-1 data logger, or Infinity ECU. The
following CAN configuration and message definition information is provided below to facilitate interface with third-party
devices.
Bus Termination
All AEMnet/CAN networks must be terminated to have an
equivalent of approximately 60 Ohms of resistance.
Generally, this means a 120 Ohm resistor connected in
parallel to /AEMnet- (or CANH/CANL) at both
physical ends of the bus run. The unit does not have any
internal termination and is intended to be connected to a
pre-existing, properly terminated network. Please refer to
the Bosch CAN2.0B specification for further detail.
