DVD128.04 New DATALOGGER Signal Grouping Feature (SSM54458)

Introduction

Jaguar Land Rover Service Diagnostics would like to announce the introduction of a new Datalogger Signal Grouping (DSG) feature.

In reaction to user feedback regarding the difficulty and complexity involved with using the datalogger interface, a simple strategy has been introduced on DVD128.04 that greatly improves this interface by reducing tedious processes while allowing users to explore the full functionality available.

DSG allows users to create unique signal groups conforming to individual user's needs that can be recalled over an over again when needed with only a few quick mouse clicks.

Overview

There are a few new processes techs must understand to begin using the DSG feature.

• Creating new signal groups
• Recalling existing signal groups
• Transporting/backing up signal group files.

Creating New Signal Groups

No special training is required to create new signal groups. Using the existing datalogger interface, select and configure up to 16 datalogger signals for viewing live. You may also change the signal order, scaling, display type, triggers etc and create the "perfect" arrangement of signals as you see fit for a given purpose.

Once you have the live display set-up and working to meet your needs, use the new "Save Signals" button (file cabinet with arrow down icon) just above the "start/stop" live display button in the datalogger button bar at the right side of the screen.

When the "save file" dialog window appears, select a meaningful file name that will allow you to recognize the purpose of that signal group. Files will be saved in the required "default" location, the "My Documents" folder in Windows ®.

New DSG files created by users are automatically assigned to the model/MY range of the vehicle specs for the current session. (see full explanation below)

Recalling Existing Signal Groups

Recalling existing signal groups for viewing live data is accomplished with even fewer steps. When viewing the signal selection screen, locate and click the new "Recall Signals" button (file cabinet with arrow up icon) near the top of the button bar at the right side of the screen. This will pop-up a list of available "DSG" files for the current vehicle specification, found by datalogger in the "default" location, the "My Documents" folder in Windows ®. (see full explanation on page 3 of this document) Select the desired DSG file and the signal group will get loaded into the live display viewer within datalogger, with all the saved signal order, scaling, display type, triggers etc. Click the "play" button and begin viewing live data.

DSG signal recall and display allows the user to display previously configured signals with only a few on-screen clicks, making the datalogger environment a much more user friendly and faster process!

Transporting / Backing-Up Signal Group Files

DSG files are saved to the "My Documents" folder by default, with the file name assigned by the user. DSG Files can be identified by the "DSG_" preceding the user assigned name, as follows. "DSG_< user assigned name >.XML"

At the initial launch of the DSG features within datalogger, there are no automated DSG file export/import functions. Users that desire sharing DSG files across multiple IDS laptops must manually export/import DSG files from/to the My Documents folder.

Likewise when any IDS laptop requires a static restore and full system recovery, DSG files must be manually backed-up and exported to a flash drive BEFORE executing a Phoenix Recovery/Static Restore process.

DSG File Associations And Vehicle Model Lines

When new DSG Files are created, the correct compatible vehicle model line is automatically assigned by datalogger to that file. When recalling DSG files datalogger will only present files compatible with the current vehicle specification.

Users must create unique DSG files for each vehicle variant for any given list of datalogger signals. (see chart on last page of this document)

For example, if one decides to create a DSG file for oxygen sensors and fuel trim values, to cover all "Range Rover Sport" vehicles, a total of 3 files would need to be created, one to cover 2006 > 2009 MY vehicles, another to cover 2010 & 2011 MY, and a third to cover 2012 MY. And if one wanted to expand this to cover LR3/LR4, 3 more DSG files would be required.

Remember datalogger automatically assigns these model/MY ranges to any new DSG files created. When selecting signals to be recalled, only the correct files will be offered. So regardless of the fact Jaguar Land Rover mfg's several vehicles with a similar 5.0L Engine and ECM, files created for 5.0L Engine signals on a LR4, will not be offered for other 5.0L equipped vehicles.

Another point to remember is that when a DSG file is loaded that includes specific datalogger signals that are not applicable to the current vehicle due to "optional equipment" such as a Rear Differential Control Module, those signals will be ignored and will not be added to the live display. Under these circumstances, SDD is expected to inform the user regarding this conflict using a pop-up message window. The remaining applicable signals will be added to the live display.
