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. KIT CONTENTS 1 x AQ1 Data Logger Harness Plug and Pin Kit 1 x Bag of 20 Terminals WIRING Power Connections RED (PERM PWR)- Connect to a fused (5 Amp) constant 12 volt power source. RED (SWIGN) – Connect to a fused (5 Amp) switched 12 volt power source. BLACK (BATT GND) – Connect to a clean power ground. (Do not connect to a sensor ground) 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.
Page 3 10-2906-0 AQ1 Harness Instructions RevA 110707.doc 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 1. Figure 2 below shows the connection for an engine speed signal using an AEM Twin Fire CDI. Figure 1. AEM Pressure Sensors(Left) AEM Temp Sensor (Right)
Page 4 10-2906-0 AQ1 Harness Instructions RevA 110707.doc Digital 1-3 are switched to ground digital inputs, 16.5 V MAX tolerance. Examples: Clutch/brake/cooling fan ground switch, nitrous solenoid ground or ground switch input to start/stop Logger (Ground activated input). Figure 3 below shows wiring diagrams for an on/off activation switch and a nitrous solenoid. The corresponding wires in the harness for Digital 1-3 are Brown and are labeled SW 1, SW 2, and SW 3. SENSOR POWER The AQ1 Data Logger has an internal low current 5 volt power supply that is used for powering sensors that require a 5 volt excitation. The corresponding wires in the harness are Red and are labeled 5 VOLTS. SENSOR GROUND The AQ1 Data Logger also has an internal low current sensor ground that is used for sensors that require a signal ground. The corresponding wires in the harness are Black and are labeled SIG GND. Figure 2. Engine RPM Signal From CDI Figure 3. Activation Switch (Left) and Nitrous Solenoid (Right) Connections
Page 5 10-2906-0 AQ1 Harness Instructions RevA 110707.doc RS 232 The RS232 serial input on the AQ1 Data Logger is configurable to read either a standard NMEA GPS data stream or the data stream from an AEM EMS. See “Using the AQ1 Data Logger” for more information on configuring the RS232 input. The AQ1 Data Logger harness comes with a male DB9 connector. When connecting to an AEM EMS, the male DB9 connector plugs directly into the mating connector on the back of the AEM EMS. The pinout for a GPS connection is shown below in Figure 4. AEM recommends using one of the Garmin GPS models listed below. Garmin GPS 18x PC – 1 Hz model with DB9 connector and 12 volt power adapter Garmin GPS18x 5Hz- 5 Hz OEM model, some wiring required. CAN BUS 2 Not used with AQ1 Data Logger PN 30-2500 USB The AQ1 Data Logger has two USB ports for easy connection and programming. The AQ1 Data Logger receives low voltage power from the USB port, allowing users to access the SD card and make configuration changes at all times, 12 volt power is not necessary. The black remote mount USB port in the harness is designed for easy in vehicle programming and data downloads. The USB port on the back of the enclosure allows for easy bench top programming and data downloads when the module is removed from the vehicle. See Figure 5 below. Figure 4.
