KEYBOARD CONFIGURATION

Note: The White Button (DISPLAY RATE) is a shift key. Press it first, and hold it down, while pressing another button to execute the function that is printed in white letters.

INSTALLATION / CONNECTIONS

The Data Logger is installed in series with your Digatron instrument and sensors. Connect the short pigtails on the DT-41 to your tach and mph sensors. It is not necessary for both sensors to be connected to the Data Logger, but all sensors on the Digatron instrument must be connected. Connect the long pigtails on the Data Logger to your Digatron instrument pigtails. Connect the marker switch to the pigtail with the white band on the Data Logger.

POWER ON

If you do not want to begin recording data when the engine starts, turn the Data Logger on by pressing the POWER ON button before the engine is started. Recording will not start until you press either the remote MARKER switch or the START/PAUSE button on the Data Logger.

A low battery (Lo b) indicator will appear on the DT-41 display about five hours before the battery needs to be replaced.

SETUP (CONFIGURING INSTRUMENT)

To enter the setup mode, press and hold the FASTER button and press the START/PAUSE button. The display will show a S , a 7 ¯ , or a 7 ¯ S. Press the FASTER button to select the desired operating mode.

While still in the setup mode, press the DISPLAY RATE button to change the display from input setup to record rate setup. The current record rate will be displayed. Press the FASTER button to change your record rate. Your record rate affects how often data is updated, how precise your markers are, and how long the instrument will record date.

Time Available (Min: Sec)

Press the START/PAUSE button to exit the setup mode. The display should show 0:00.0 with the colon and decimal blinking. This indicates that the instrument is ready to record.

RECORDING DATA

To AUTOMATICALLY begin recording data, start the engine before the DT-41 is turned on. To MANUALLY start recording data, turn the Data Logger on before the engine is started. Press the remote MARKER switch or the START/PAUSE button to begin recording data.

During the data recording session press the remote MARKER switch to mark points in the recording stream that you want to look at later (e.g. entering or leaving a corner). There are no restrictions on the number of markers that you can place while recording data. When a marker is placed, the unit displays the time between markers. This function allows the data logger to be used as a lap timer.

Use the START/PAUSE button to start and stop recording. Recording will stop automatically when the maximum record time has been reached. When the START/PAUSE button is used during the data recording session, the time displayed will equal TOTAL RECORDING TIME only. The displayed time will not relate to the actual time of the session.

WARNING: All previously recorded data is lost when you enter record mode and start recording at 0:00.0. There are two ways to lose your data. If your engine starts while the Data Logger is off, all old data is lost. Data can also be lost by pressing the START/PAUSE button while the instrument is in record mode. Either method will cause the DT-41 to start recording data and erase all old data.

LAP TIMER

When markers are set while recording, the data logger displays the time between markers. This allows you to use the data logger as a lap timer, if you press the MARKER at the same point on the track each time around. For the most precise lap times use the 1/10 second record rate. The data logger will continue to show the lap time until you press the DISPLAY RATE button, which returns the display to elapsed record time.

RESETTING the RECORD MODE

To reset the time to zero while recording, first pause the instrument. Then press and hold the START/PAUSE button and then press the SLOWER button. When you begin recording again it will write over all previous data.

SELECTING RECORD / PLAYBACK MODES

To enter the playback mode, first press and hold the DISPLAY RATE button and then press the REC/PLBK button. When you are in the playback mode an ARROW will appear in the upper left corner of the display window. Press the same buttons to reenter the record mode and the ARROW in the display will disappear.

PLAYBACK OF DATA

When in playback mode, press the START/PAUSE button to view the recorded tach and/or speedometer data saved during the last session. The recorded data will be displayed in the appropriate window of your Digatron instrument.

At any time during playback you may freeze the display of data by pushing the START/PAUSE button. This will stop the playback until you push the START/PAUSE button again.

The ARROW in the upper left corner will blink when the playback time reaches a location where a marker was placed during record. If you wish to go to the next stored marker, press and hold the DISPLAY RATE button and then press the GO TO MARKER button. The data logger will display the time between markers as long as you hold these buttons down. When you release the buttons the time of the marker placement will be displayed.

RESETTING the PLAYBACK of DATA

To reset the time to zero and view the information from the beginning, press and hold the START/PAUSE button and then press the SLOWER button.

PLAYBACK DIRECTION

You can choose to view the recorded information either forward or backward. Initially the data will be displayed with time going forward. To change playback direction, press and hold the DISPLAY RATE button and then press the « button.

PLAYBACK SPEED

While in Playback mode, press and hold the DISPLAY RATE button to show the current playback speed of the unit. Press the FASTER button to increase the playback speed of the instrument. Press the SLOWER button to decrease the playback speed.

The playback speeds are 1/8x, 1/4x, 1/2x, 1x, 2x, 4x, 8x, 16x, 32x, and 64x the recorded speed of the data.

NOTE: It is possible for data playback to occur so fast that your instrument may not properly display the stored information. If this occurs, choose a slower playback speed.

TURNING UNIT OFF

The Data Logger must be paused before it can be turned off. Press and hold the FASTER and SLOWER buttons. The unit will turn itself off automatically after 10 minutes if no tach input, mph input or button presses are detected.

All the recorded data will be retained when the DT-41 is turned off, but it will be lost if the engine is turned on again before turning the Data Logger back on.

NOTE: If the unit is connected to an engine, the unit will not turn off while the engine is running.
