AEMnet 

AEMnet is an open architecture software and hardware interface based on the CAN 2.0 specification, 
which provides the ability for multiple AEMnet enabled devices to easily communicate with each other 
through a single cable. The hardware connection is made through a Deutsch 4P DTM connector. 
Devices connected to the AEMnet transmit data through this one connection. Once the AEMnet 
adapter is installed, the Series 2 EMS will be able to send and receive data on the AEMnet. 
Instructions for configuring the Series 2 EMS to output data are included in this manual. Instructions 
on configuring the Series 2 EMS to receive data from other AEMnet enabled products are contained 
in the individual product manuals. Upon completion of these instructions, the Series 2 EMS will be 
configured to output data to an AQ1 Data Logger or other data receiving device.  
 

The following AEM products are currently AEMnet enabled: 
 

Series 2 Engine Management System 
 
EMS-4 Universal Standalone Engine Management System 
 
4-Channel Wideband UEGO Controller 
 
AQ-1 Data Logger 
 
Dyno Shaft On-Vehicle Dynamometer
