Plug the Deutsch 4-pin DTM connector on the AQ1 Data Logger harness into the
mating connector on othe
r AEMnet compatible devices. See “Using the AQ1 Data
Logger
” for more information on configuring the AEMnet.
INPUT SIGNALS
Analog 1-4 are 0-5V analog inputs with optional pull-up resistor for RTD/Thermistor-
style sensor. Examples: AEM gauges, MAP/pressure sensors, TPS/APP/shock
travel/load cell sensors, analog MAF sensors, any 2 wire RTD or thermistor style temp
sensor.
See “Using the AQ1 Data Logger” for more information on configuring Inputs 1-
4. The corresponding wires in the harness for Analog 1-4 are Yellow and are labeled
INPUT 1, INPUT 2, INPUT 3 and, INPUT 4.
Analog/Frequency 5-8 are analog inputs for that can optionally measure frequency (0-
5 V or 0-16 V) Examples: RPM, vehicle speed, frequency based MAF, injector duty
cycle, boost control solenoid, flow sensor, hall sensor, any 3 wire pressure sensor. See
“Using the AQ1 Data Logger” for more information on configuring Inputs 5-8. The
corresponding wires in the harness for Analog/Frequency 5-8 are Yellow and are
labeled INPUT 5, INPUT 6, INPUT 7, and INPUT 8.
Connection diagrams are shown below for some of the more common sensors/signals
to be used with Inputs 1-4 and Inputs 5-8. See Figure 2.
