Record and Playback
The Record function lets you record up to 150 one-sec-
ond frames of data (75 frames that occur before
pressing the Record function key and 75 frames that
occur after pressing the key). The Playback function
lets you replay recorded data. You can also save and
delete recordings.
Record a Data File
To record a data file, follow these steps:
Figure 3.3: Datastream Screen - Record Function
1 With the Datastream screen displayed, press the Record
function key. This does the following:
• Temporarily shades the Record function key.
• Automatically records the past 75 frames of data that
occurred before pressing the key and continues
recording the next 75 frames of data as they occur.
• Displays a countdown on the status line of the number
of frames left to be recorded (from Recording: 75 to
Recording:1). When the countdown reaches 1, the
recorded data is saved as an Event file and placed in
a Playback folder.
Note: To record less than 150 frames of data, press the
EXIT key at any time. This stops the recording and saves
only the frames already captured.
2 When the recording completes, continue viewing live data
or press the EXIT key to return to the Diagnostic Menu
screen.
3 Refer to the next section for playback steps.
Playback a Data File
To replay a recorded (saved) data file, follow these
steps:
1 Press the MENU key to display the Application Manager
screen.
2 From the Application Manager screen, select Playback.
This displays the Events to Playback screen.
Note: The Events to Playback list holds the recordings.
When the list is full, old recordings automatically delete as you
make new recordings. To prevent a recording from being
automatically deleted, highlight the recording and press the
Save function key. This places a disk icon to the left of the
file name and saves the recording until you delete it. (Use the
Delete function key to delete a selected recording.)
Figure 3.4: Events to Playback Screen
3 Select the recorded event to replay and press the
ENTER key. (The events are identified by the vehicle
description, date, and time of the recording.) The
recorded event displays on either the DTC display screen
or the Datastream screen, depending on the type of
recording (Fault Codes or Live Data).
4 If the Datastream screen displays, use the Left and Right
Direction keys to view the data. The Frame number in the
status line changes as you move through the recording.
Note: There may be a DTC function key you can use to
view a list of any DTCs that existed at the time of the
recording. You can use the To Top function key to move
a selected line to the top of the screen. You can also use
other functions of the Datastream screen, such as Graph,
Print, Zoom, and Sort. Refer to the steps for these on the
next few pages.
5 When you are finished viewing the recording, press the
EXIT key to return to the Application Manager screen.
