AEM Performance Electronics CD-7 - AEMnet (CAN Bus) Output; Bus Termination

37
AEMnet (CAN Bus) Output
WHITE WIRE = AEMnet+ / CANH
GREEN WIRE = AEMnet- / CANL
CAN DBC definition files are available at

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+/AEMnet- (or CANH/CANL) at both
physical ends of the bus run.

22 Channel CAN Sensor Module to Dash
Kit Contents
The AEM 22 Channel CAN Sensor Module enables a user to put analog, digital, and frequency signals on to an
AEMnet or CAN bus. The Sensor Module accommodates a wide variety of sensors and is housed in a sealed IP65
weather-resistant enclosure. Sturdy construction, protected inputs, and simple configuration make this the perfect
entry point to get everything required to use an AEM CD-series dash on a carbureted or EFI vehicle. The Sensor
Module supports the Bosch CAN 2.0b standard with flexible CAN configuration jumpers making it compatible with
many third-party devices. Note: The only AEMnet devices that are compatible with the CAN Sensor Module are the
CD-series dash displays.
Features
· Four (4) dedicated 0-5V analog inputs
· Four (4) user-configurable analog inputs, (jumper
selectable; 0-5V, thermistor, or RTD)
· Four (4) temperature (thermistor) inputs
· One (1) dedicated fuel level input (0 to 250 Ohm
range)
