  • Page 11 ANALOG/FREQUENCY 5-8 INPUTS The analog/frequency 5-8 pages are similar to the Analog 1-4 pages. In addition to measuring voltage signals, Analog/Frequency channels 5-8 are also capable of measuring pulse based signals. Some examples of pulse based signals are engine rpm, MAF, vehicle speed, wheels speed, and driveshaft speed. The analog/frequency channels can also measure signals up to 16.5 volts.
  • Page 12 Figure 14. Digital 1 Page with Inverted Input BATTERY VOLTAGE The Battery Voltage page is shown below in Figure 15. The battery voltage is measured on the red switched ignition wire (SWIGN). See the section on “Power Connections” for wiring information. Figure 15.
  • Page 13 The sample rate is the rate at which the AQ1 Data Logger records the data. When logging the data stream from an AEM EMS, the input mode must be set to AEM EMS. The baud rate must be set to 19200. Figure 17 below shows the AQ1 Data Logger configured to log an AEM EMS.
  • Page 14 AEMnet The AEMnet page is used to select what parameters are logged from the AEMnet. Devices connected to the AEMnet are automatically detected and require no configuration. The AEMnet page is shown below in Figure 18. Figure 18. AEMnet Page LOG NOTES User notes can be entered in the Log Notes page.
  • Page 15 LOG FILES Log files are automatically stored on the SD card with an “.AQ1” file extension. Before viewing the data, the “.AQ1” files must be downloaded to your hard drive where they are saved as “.DAQ” files for viewing in AEMdata. The files will be automatically downloaded when you connect to your device with the AQ-1 software as shown in Figure 20.
  • Page 16 A user may configure the location where the log files are downloaded and saved to on the ‘Log Files’ page as shown in Figure 21. In addition, there is a command button to manually download logs from source folders other than the AQ-1; for example, an SD card mounted in an external card reader.
