Thank you for your purchase! This instruction

manual will guide you through the installation and

operation of your eLogger.

Please read the entire manual carefully before

proceeding. If, after you read the manual

(including the Troubleshooting sections!) you have

further questions or problems, please visit our web

you important update information.

Key Features

Here are a few of the features of the eLogger:

• Logs pack current to +/- 100 amps (150

amps with MPRV4-LEADS-150) and

voltage from about 5 volts to 80 volts

• Current is measured with a true Hall Effects

Sensor - NOT a power robbing resistance

shunt

• Adjustable logging rate (from 50 samples per

second to one sample every 5 minutes)

• 16 times the logging space of the standard eLogger V3, and lossless data compression. Typically logs all

available sensors for about four hours, at 10Hz.

• All data are logged to permanent memory, which retains the data even when the power is removed

• Fully compatible with our OSD Pro expander

• Includes Y cable for throttle position logging

• Great for bench monitoring of battery charging also!

• Supports the PowerPanel LCD Display

• Accepts optional inexpensive sensors for three Temperatures, RPM (brushless, magnetic or optical), Airspeed,

Altitude, GPS, Servo Current, and more

• Software computes Wattage, mAH, etc. for complete e-flight data.

• Fully Compatible with Windows 7 (32 and 64 bit), Vista, 98SE, ME, Win2K and XP™

• Weighs about 0.8 oz (22 grams). Versions with Wire Leads may weigh slightly more.

• Comes with our state of the art Windows virtual playback display and graphing software

• Powerful Graphing software has advanced charting features, such as amps vs. volts

Page 2 • • • Internet Updatable firmware - as we add new features or (heaven forbid) have a firmware bug, the update is just a download away! No need to ship hardware back and forth. Full support for English and Metric units. Software has built in English, German and Chinese languages. Intended Uses The eLogger was designed for use in Unmanned Radio Controlled models. It is intended to be used exclusively in model planes, boats and cars. Using the eLogger for other purposes is not supported.

Page 3 IMPORTANT: Do not leave your model’s power system connected to the eLogger when the unit is not in use in the field. Always disconnect the battery from your model when it is in storage.
PAGE 4
Page 4 To install our magnets, first find a suitable location on your motor or drive train to attach either one or two small magnets and RPM sensor. Typically, the spinner back plate prop or prop adapter are ideal locations for planes, and a car’s axle shaft is good for car installation. This will of course vary with the construction of the model. Make sure the magnets are mounted on some structure that doesn’t “flop around,” as the magnets could hit the sensor in this case.

Page 5 Several of our customers have been able to use existing RPM sensors, such as governors or turbine sensors, with our products. The following steps must be followed: 1) Determine the “pinout” of the existing sensor. Compatible sensors will have Power, Ground, and Signal connections. The eLogger’s RPM pinout, from left to right, is: Power (black wire), Ground (red wire), Signal (white wire).

Page 6 Installing and Using the Windows™ Software The eLogger V4 is configured, and data is downloaded, using our powerful Windows software. Please read the information below on installation, configuration, and data download. Installing the Windows Software The supplied Windows software is compatible with USB equipped PCs running Windows 7, Vista, XP, Windows 98SE, Millennium, or Win 2K. The software is NOT compatible with Windows 98 Original Edition (Gold), or NT 4, even if the PC has USB support.
PAGE 7
Page 7 Setting up the eLogger with the Windows Software Once the software is installed, run the software as described above. The first time the software is launched, the New Model Wizard will be invoked. The Wizard will prompt you to install the eLogger using the supplied USB cable.
PAGE 8
Page 8 The more items you log, the less record time will be available. A description of the parameters is below: Electric Motor Voltage: If this option is selected, Pack Voltage is logged. Electric Motor Current: If this option is selected, Pack Current is logged. RPM Sensor A: If this option is selected, and you have installed an optional RPM sensor, the eLogger logs the RPM of your model. Temperature 1: Choose this option if you want to record temperature from an optional temperature sensor.
PAGE 9
Page 9 In our experience, if all sensors are connected and logged, and the capture rate is set to 10 Hz, the buffer will fill up in approximately four hours. However, the actual logging time will vary, since lossless data compression is used by the eLogger. A note on record time: The eLogger uses advanced data compression to get the most data recorded as possible.

Page 10 Note: Select the “Metric” checkbox on this dialog if you want values displayed in metric units. Configuring and Calibrating the Throttle Function of the Expander with the Windows Software Calibrating Throttle Movement It is necessary to calibrate the throttle function when logging throttle servo position. The advantages of calibration are that the throttle gauge and graphs will range from zero (closed throttle) to approximately 20 (maximum throttle), as you move your throttle between its extremes.
PAGE 11
Page 11 function test your model once the eLogger is installed to ensure that there is no impact on your system. Make sure that your “antenna down” operating range is within the manufacturer’s specifications. See your Radio owner’s manual for the correct procedure for your equipment. DO NOT OPERATE IF YOUR MODEL DOESN’T PASS THE ANTENNA DOWN RANGE CHECK. Additionally, you need to make sure that your Model’s power system is working correctly after adding any new hardware in-line, like the eLogger.

Page 12 • • Graphical and/or Numeric GPS parameters – The software displays GPS speed, course, altitude, and distance from the operator readings in either gauge or numeric format. Graphical and/or Numeric Speed (Cars Only) – The model’s speed, as computed from the RPM, can be displayed graphically and numerically. Multiple Session Support Depending on the length of your modeling sessions, it is often possible to record multiple runs into the eLogger without having to clear the buffer or overwrite data.
PAGE 13
Page 13 The eLogger’s Data File is compatible with Excel ™ spreadsheet software, and other spreadsheet products supporting space delimited data files. Using Excel™ is useful for graphing the data output from the eLogger. To load in Excel, save the data file from “File->Save Recorder File,” and in Excel™ choose File->Open, and select “All Files” in the “Files of Type” box. Navigate the Excel dialog box to the location where you saved the .FDR data file, and click on the filename.
PAGE 14
Page 14 There are many advanced features included with our software, available via the “Advanced” tab in the software. Some of these are described below: Set Logging Triggers This feature lets you select events that will cause logging to start, such as elapsed time after power-up, or threshold readings for amperage, RPM, Altitude, or when GPS fix is attained. Note that until the selected event occurs, the eLogger will be in “paused” mode, and the LED will flash two blinks in a row.
PAGE 15
Page 15 • Connect the eLogger to the computer and launch the Windows Software. Then, click the “Live Mode” button. Make sure that the RPM gauge is displayed, and spin the magnets, or wave the magnets by hand in front of the sensor. Try both sides of the magnets and both sides of the sensor. See if the RPM reading jumps. Issue: I have a fully charged battery, but the eLogger frequently shows “Low Battery Restart” Notifications when playing back data.
