Installation for Series 2 EMS 30-6040 & 30-6300
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
