7. Disconnect the DPR from the computer.
8. Turn all power settings (such as throttle) to OFF on your R/C craft before connecting to the DPR.
9. Connect the DPR to the load (ESC) first, then power source (battery).
10. The red LED should quickly flash twice to show it is getting power and is ready to record.
11. The DPR is factory set to begin recording five seconds after it is connected to a power source.
12. The green LED will light when the recording mode is activated and during recording mode.
13. After you have completed recording a mission, disconnect the power from the DPR.
14. To record another mission, reconnect a power source to the DPR.
15. To view the data, disconnect the DPR from the power source and load, and connect it to the computer with the proper USB cable.
16. Run the DPR-Graph software. It should appear as an airplane icon on your desktop.
17. The DPR-Graph software will automatically search the COM ports for the DPR and connect.
18. Click “Get Data”. The software will now attempt to download the mission data from the DPR. This will take about 3-5 seconds.
19. After the mission data has been downloaded, all recorded missions will be displayed.
20. You can now analyze the data, view any or all missions, change the display parameters, zoom in, view timespecific (or overall) statistics, add notes, and save the mission data.
CAUTION: The DPR–50 and DPR–100 are capable of measuring up to 30 Volts input at 50 or 100 Amps respectively. Working with high Voltage and Current levels can be very dangerous, or lethal. Necessary safety precautions must be taken when working with high power.

GETTING STARTED
Before you begin using your new DPR, you will need to add connectors to the red and black wire leads that correspond to your source and load connectors. These were not included since there are so many different connector options in use. It is very important to match the positive and negative leads to the corresponding leads (+ to + and - to -). The red wire leads from the DPR represent the positive (+) leads, and the black wire leads represent the negative (-) leads.
Typically, the connections should be red-to-red and black-to-black, but you should confirm the polarity of your source and load connection leads before connecting to the DPR. It is very important to make strong, solid solder joints on the connectors. We recommend you also use heat shrink tubing on the solder joints to help prevent any possible electric short between the connector leads.
The DPR was designed so that it does NOT matter which red/black pair goes to the source or which red/black
pair goes to the load. The DPR circuitry automatically detects the source and load.
Figure 2 shows a typical diagram for connecting the DPR to a battery (source) and ESC (load).

You may also connect the DPR between your charger and your batteries to analyze how the batteries are being charged. When doing this, the charger automatically becomes the source and the batteries become the load. Figure 3 shows a typical diagram for connecting the DPR to a charger (source) and batteries (load). When connecting to a charger and batteries you must take precautions to stay within the Voltage and Current parameters specified for the
DPR.

HIGH VOLTAGE CONFIGURATION
For advanced, high Voltage configurations utilizing two battery packs (OF EQUAL VOLTAGE AND CHEMISTRY) wired in series, the DPR can be connected as displayed in Figure 4. This will allow the DPR to be used in systems up to 60 Volts. With this configuration the DPR will record the full Current load, and half the total Voltage. The DPR-
Graph software can compensate for this by doubling the recorded Voltage. To do this, open the “Display Parameters” window and check “Double Voltage”. All displayed Voltage amounts will now be doubled.
NOTE: Do not connect the DPR directly to Voltage levels above 30 Volts.
Battery 1:
Up to
7s Lipo
Battery packs must be of equal Voltage and chemistry.

LOADING THE SOFTWARE
The DPR CD-ROM includes the powerful graphing software (DPR-Graph), the USB support files and a soft version of this manual. Insert the DPR CD into the CD-ROM drive. If you do not have a CD-ROM drive, you may download
the software, USB support files and DPR manual on the World Wide Web at www.bnbproducts.com. Follow the on-screen instructions to download. The CD should automatically begin to load when inserted into the computer’s
CD-ROM drive. If it does not load, click on the start/run selections at the bottom left corner of the desktop screen.
Browse to the CD-ROM drive, click on DPR-SETUP and RUN. The software should begin loading. It will attempt to create and load the DPR-Graph software and USB support files into a new folder located at C:\DPR. You may change this folder location if desired. Follow the on-screen instructions to complete the process. The default file location for saving missions is C:\DPR\MISSION FILES.
After you have installed the DPR-Graph software, you will need to install the USB support files. DO NOT run the
DPR-Graph software for this step. Connect the DPR to the computer with a proper USB cable to install the USB driver. Connect the large end of the USB cable to your computer’s USB port, and the small end to the mini USB connector on the DPR. DO NOT connect an external power source to the DPR for this step. All the necessary
power to the DPR is received through the USB cable. After connecting the DPR to the computer, a window should pop up stating “New Hardware Found”. Follow the onscreen instructions. If the installation cannot locate the USB support file, you may select “Manual Browse”. The necessary files are called DPR_2K.INF (for Win 2000) or
DPR_XP.INF (for Win XP). The default directory location is C:\DPR\USB SETUP FILES. The USB driver should install, and can now connect to the DPR.
CHANGING THE DPR RECORDING PARAMETERS (optional)
The DPR is factory set to record missions when you receive it. It is not necessary to change the recording parameters before you begin recording missions, but you have the ability to do so through the DPR-Graph software. There are five recording options you may change. These options include the recording sampling rate, channels to record, recording resolution, recording trigger, and LED alert, as described below.
5
Note: The settings for sampling rate, channels to record, and recording resolution directly affect the amount of
recording time available.
Recording Sampling Rate: The DPR is capable of recording data samples from 1 to 50 times per second. To achieve longer recording times, set the samples-per-second to a lower sampling rate. To achieve more precise sampling (or for shorter recording times), set the samples-per-second to a higher sampling rate. The DPR is factory set to record 4 samples-per-second, which should be adequate for most users.
Channels to Record: The DPR is capable of recording four base channels: Voltage, Current, Temp1 and Temp2.
Elapsed time is always recorded, and all other channels are calculated from one or more of these. Note: Current
must be set to record to view the charge used. Current and Voltage both must be set to record to view Power.
The DPR is factory set is to record the Voltage and Current.
Recording Resolution: The recording resolution sets the resolution of the channels being recorded. The resolution mode can be set to “Standard” or “High” resolution. Setting the resolution to “High” will allow the DPR to record the
Current at 2x and Voltage at 4x the “Standard” resolution. The DPR is factory set at “Standard” resolution. To activate “High Resolution”, check the box next to “High Resolution”.
Recording Trigger: The DPR recording trigger tells the DPR when to begin recording after it is connected to a power source. It can be set to begin recording at the first current load (from 3 to 20 Amps), or at a specific elapsed time after it is connected to a power source (from 2 – 129 seconds). The DPR is factory set to begin recording 5 seconds after it is connected to a power source.
LED Alert Settings: The LED alert settings may be used with the optional temperature probe / LED Alert Indicator
(TMP-LED). You may select alert levels for Voltage, Current and/or temperature. When any of these are activated, the LED probe will flash when the levels are reached.
To change any of the recording parameters, connect the DPR to the computer as previously explained and run the DPR software. The software will attempt to connect to the DPR COM port. If it is unable to connect to the DPR, you can manually select the COM port or “scan” in the “port” menu at the top of the screen. After connected, the screen will display “Digital Power Recorder (DPR) found on COM port X”. Click the “Recording Parameters” button.
The software will attempt to download, and display, the current recording parameters from the DPR. You may change any parameter, then click “Update” to set the new recording parameters. If the DPR is not connected, a message will display stating “Not Connected to DPR”, all fields will be locked, and the last known values will be displayed.
Note: The DPR recording parameters may only be updated when the DPR memory is empty. If you attempt to open the Recording Parameters window while the DPR still has missions stored, you will be instructed to clear the stored data before updating is possible.
RECORDING MISSIONS
Make sure all control settings on your R/C device (such as throttle) are set to OFF. Connect the electronic speed control (ESC) “load” first, then the power source (battery) to the DPR. Always connect the load first and the power
source last. Once the power is connected, the red LED will quickly flash twice to indicate it is getting power. It will continue to flash, indicating how much recording time is remaining - one flash/pause (0% - 25% full), two flashes/pause (26% - 50% full), three flashes/pause (51%-75% full), constant flashes (76% - 99% full), constant
on (100% full). When the LED is constant on, the memory is full, and it can no longer record additional data until the stored data is uploaded to a computer or manually cleared using the jumper (discussed later).
After the DPR is connected to the “load” and power “source” and the recording is triggered, the green LED will light.
It is now recording. The DPR is factory set to begin recording five (5) seconds after power is connected. It will continue to record data until the battery is discharged below 7 Volts, the power source is disconnected, or the memory is full. The green LED will remain on until the recording is stopped.
6
After you have completed a mission, unplug the power source from the DPR. The data will not be lost when you
disconnect the power from the DPR. To record another mission, reconnect a power “source”, and trigger the recording mode as before. The DPR will automatically separate each recorded mission. You will be able to graph each mission separately, or all missions side-by-side for comparisons.
Note: The DPR needs at least 7 Volts input to activate the recording trigger. If the input Voltage drops below 7
Volts while recording, the data may become increasingly inaccurate or erratic. Because of this, the DPR is programmed to go into “sleep” mode and stop recording if the input Voltage drops below 7 Volts (without the
USB connected). If this occurs, both LEDs will turn off and the power source must be disconnected to reset the unit before continuing to record.
USING THE USB CONNECTION WHILE RECORDING (Bench Testing)
You may record the battery Voltage down to 0 Volts with the DPR if you connect the USB cable to the computer and the DPR as a secondary power source. First, connect the DPR to the computer as previously discussed. The red LED should flash to indicate the amount of memory available. When you are ready to begin recording, connect the “load” then the power “source” to the DPR. Trigger the recording mode as before to begin recording.
Note: It is not recommended to discharge a battery completely to 0 Volts. This could permanently harm the
battery. See your battery manufacture’s specifications for the suggested minimum discharge Voltage.
USING THE SOFTWARE
GRAPHING THE DATA
Once you have acquired the data in the DPR, you may then upload the data to your computer for graphing. Connect the DPR to the computer with the USB cable as previously described.
Note: The first time you run the DPR-Graph software, you will be asked which model you are using (DPR-50 or
DPR-100). It is important to select the correct model. Selecting the incorrect model will result in incorrect
Current graphs, Current trigger, and Current alerts. When a mission is saved, the model configuration is also saved with the mission data file. If you are using the software only to view sample or saved mission files, it is unnecessary to configure the model. When viewing saved missions, the configuration will automatically adjust to the mission being opened.
Run the DPR-Graph software. The software will attempt to connect to the DPR COM port. If it is unable to connect to the DPR, you may manually select the COM port or select “scan” from the “Port” menu at the top of the screen.
After connected, the screen will display “Connected to DPR”. Select “GET DATA”. The computer should now download the stored information from the DPR. The memory in the DPR will also now be cleared and ready to record more data. The data will download within approximately 3-5 seconds. Once the download is complete, all recorded missions will be displayed side-by-side. If multiple missions were recorded, a gray vertical line will divide each mission. You may also view any of the missions independently by clicking on the “VIEW MISSION” drop-down list.
A drop-down list box will appear. Select “ALL”, or one of the missions listed. The selected mission(s) will be displayed in the graph window.
NOTE: Once the data has been uploaded to a computer, it will be stored in a temporary file, and the memory in the
DPR will be automatically cleared and ready to record a new mission. You will have the option to save the mission on the computer. You can manually save the mission to the computer by selecting the “File/Save As” menu at the top of the page. The software will also ask you to save the data upon exiting if you did not manually save the data. The temporary mission files are saved as C:\DPR\mission files\tempmissionfile.dpr.
CHANGING THE DISPLAY PARAMETERS
The DPR software also allows you to view/change the Display Parameters, as discussed below. The “Display
Parameters” button is used to view/change the settings of the display data. These options include:
7
Channels to View: You may select to graph any, or all, of the recorded channels. This includes the Current, Voltage,
Temp1, Temp2, and Power. Click on the box next to the appropriate channel to toggle ON/OFF. Select “Update” to update the graph. You may also toggle the channels by clicking on the item in the legend. Current must be set to record to view the charge used. Current and Voltage both must be set to record to view Power. Elapsed time is always displayed.
Change Graph Colors / Line Thickness: You may change any of the graph’s line colors or line thickness. To change a line color, click on the word “color” next to the desired channel. A color box will appear. Click on the desired color and click “Update”. To change the line thickness, adjust the “line thickness” slider bar and click “Update”.
View Power in 10X mode: The Power is calculated by multiplying the Voltage by the current. Because of this, the
Power graph numbers are typically much higher than any of the other channels. This may make the overall graph more difficult to read. To compensate for this, you may select to view the Power graph in 10X mode. This will divide all Power amounts by 10 to lower the numbers for easier viewing. Click on the box next to “Power 10X” to toggle ON/OFF and select “Update”. The default setting is OFF.
View Double Voltage: For high Voltage configurations as discussed on page 5, the Voltage recorded will be half of the actual Voltage used. Select the “Double Voltage” option to compensate for this. This will double the graph levels of the recorded Voltage. NEVER CONNECT MORE THAN 30 VOLTS DIRECTLY TO THE DPR.
Temperature F/C: The temperature readings may be displayed in Fahrenheit or Celsius. Select the desired choice and click “Update”. The default setting is Fahrenheit.
SAVING THE DATA
You may save the mission data by selecting the “File / Save As” option. The software will always save the file as a
*.DPR file. You will have the option to also save the file as a *.TDL file. The *.TDL file represents a Tab-Delimited file. The *.TDL file may be opened by spreadsheet programs, such as Excel, or a text editor. You also have the option of saving only the mission being viewed, or all missions together.
ZOOM
If you are viewing a graph with a long time frame, the minute changes may become increasingly more difficult to view, or invisible. To compensate for this, you may zoom into any specific area of the graph. Click the left mouse button on the graph and a vertical cursor will appear as the zoom starting point. You may drag the cursor to the desired point by holding down the button before releasing. The cursor will be set when you release the mouse button.
Repeat for the ending zoom point. The graph will zoom into the area specified. You may use the scroll bar at the bottom of the screen to scroll the graph left or right. Clicking the scroll arrows will scroll ¼ page and clicking the area next to the scroll tab will scroll ½ page. Return to normal viewing by clicking the right mouse button. You may also quickly zoom into a 1-second time frame by double-clicking the left mouse button on the graph.
STATISTICS WINDOW
The statistics window is displayed on the left side of the screen and is always on when viewing a graph. It gives all of the statistics for the total missions or individual mission being displayed. The statistics only displays the values for
the area being displayed. If a channel was not recorded, “N/A” will be displayed for that value.
Following is the list of statistics displayed in the Statistics Window:
Time of mission
Rate SPS (samples per second)
Charge (mAh) used
Battery Efficiency
Max Power, Avg Power
Max Current, Avg Current
Max Voltage, Avg Voltage, Min Voltage
Max Temp1, Avg Temp1
Max Temp2, Avg Temp2
8
“Battery Efficiency” may be used to help you determine how the battery Voltage changes at different current loads.
As the Current load increases, the Voltage available from the battery typically decreases. Some batteries may hold their Voltage output better than others at higher Current loads. The Efficiency Statistic takes the Voltage level at the point of the max Current load, and divides that Voltage by the max Voltage recorded to give you the percentage of the full Voltage at that point.
For example, consider the following possibilities:
Max recorded Voltage is 12 Volts,
Max recorded Current load is 20 Amps,
Voltage at 20 Amp Current load is 9 volts.
(9 / 12) x 100% = 75%
This indicates that your batteries are operating at 75% of max Voltage at a 20 Amp Current load. This should only be used as a general guide, and not as an exact representation of the batteries actual performance capabilities. Consult your battery manufacture’s data specifications for exact battery capabilities and limitations.
TIME-SPECIFIC STATISTICS
You may also view time-specific statistics. To do this, hold down the ALT button and click on a point on the graph with the left mouse button. When you click the mouse, a vertical cursor will appear. You may drag the cursor to a specific point by holding down the left mouse button. The cursor will set and the statistics window will appear when the button is released. This will open a window showing the statistics at that specific point in time.
Click OK to close window.
The Time-Specific Statistics window displays the Elapsed Time, Power, Current, Voltage, Temp1, Temp2, and Charge
(mAh) at that specific time. “N/A” will be displayed after any statistic that was not set to record.
ADDING NOTES TO MISSIONS
You may add notes - such as the date, battery type/configuration, and electronics used to any of the missions being displayed. Type the notes in the white box provided at the top of the screen. The notes will be saved along with the data when saving. Notes may be saved for EACH available display option in the “View Mission” drop-down list box.
MANUAL MEMORY CLEAR
Each DPR unit includes a jumper connector. The jumper can be used to manually clear the memory from the DPR.
To manually clear the DPR memory, disconnect the power source from the DPR. Connect a jumper to either the top or bottom two pins of the 4-pin connector. Connect the power source (battery) to the DPR. When the red and green
LEDs flash, the memory will be cleared. You must disconnect the power source from the DPR for at least one second to reset the unit to continue. NOTE: This will clear ALL of the stored missions in the DPR.
RECORDING TIME
The DPR is capable of recording over 9 hours of data. The length of recording time available is determined by the sampling rate, the recording resolution, and the number of channels set to record.
For example, if the DPR is set to record only one (1) channel at one (1) sample per second, with resolutions at
“standard”, it will be capable of recording 32,704 seconds (9.08 Hours) of data.
On the other extreme, if the DPR is set to record all 4 channels (Voltage, Current, Temp1, Temp2) at 50 samples per second, and resolutions set at “High”, it will be capable of recording 215 seconds (3.58 minutes) of data.
The DPR is factory set to record 2 channels (Voltage and Current) at 4 samples per second with resolutions set to “Standard”. This should be adequate for most users and allows for 4088 seconds (68.13 minutes) of recording time.
