Page 2 10-2906-0 AQ1 Harness Instructions RevA 110707.doc
The 30-2906-0 AQ1 Data Logger Harness Plug and Pin Kit is designed for applications
requiring a custom harness or for applications not using the hard wired analog,
analog/frequency, or switch-to-ground inputs. The plug and pin kit harness comes with
the necessary AEMnet, Power/Ground, RS232, USB, and CAN leads. The pin locations
for the analog, analog/frequency, and switch-to-ground inputs are not populated. A bag
of 20 terminals is included for connecting the analog, analog/frequency, and switch-to-
ground inputs.

AEMnet
AEMnet is an open architecture software and hardware interface based on the CAN 2.0
specification, which provides the ability for multiple enabled devices to easily
communicate with each other through a single cable. The hardware connection is made
through a Deutsch 4P DTM connector and contains 12 volt switched power and ground
(2A max) as well as the CAN data lines. Devices connected to the AEMnet transmit
data through this one connection and most of these devices receive power from this
same connection as well.
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
Plug the Deutsch 4-pin DTM connector on the AQ1 Data Logger harness into the
mating connector on other AEMnet compatible devices.
